1.0 INTRODUCTION

1.1 OVERVIEW As part of a larger commitment to the reduction of operating costs, as well as greenhouse gas emissions, the Lunenburg County Lifestyle Centre (LCLC) commissioned a Detailed Energy Audit in July of 2020. (Appendix A). We are now soliciting proposals for Design, Tender and Project Management services to implement the recommendations resulting from the Detailed Energy Audit.

The LCLC views the scope of work detailed in this document as Phase One. Phase Two will be the addition of an integrated dehumidification solution for the arena. We are not seeking proposals for dehumidification at this time however we will want to understand how modifications in the current Phase of the project will lend themselves to the dehumidification solutions in Phase Two.

The LCLC has worked with Efficiency Nova Scotia (ENS) to secure an incentive funding estimate based on the calculated energy savings through implementation of measures detailed throughout this document. The successful proponent will be required to meet ENS Custom Program requirements in the Measurement and Verification (M&V) in order to ensure that the realized savings match the projected savings.

1.2 BACKGROUND

The LCLC is a multi-purpose facility opened in 2013. The sport, recreation, and community facility houses an NHL-size arena (Clearwater Seafoods Arena) with a capacity to seat 1,200 spectators; an aquatic centre (BMO Financial Group Aquatic Centre) suited to both leisure and competitive users; a therapeutic pool; and a public library. Other multi-purpose spaces include administrative offices, community and cultural spaces, and areas capable of hosting meeting, exercise classes, senior citizens’ activities, and many other functions.

The exterior of the building consists of metal cladding walls with a built-up roof. Estimated insulation values of R-12 and R-25 have been attributed to the walls and roof respectively. The windows are aluminum frame double pane glass type with an estimated insulation value of R-2.5.

Mechanical Systems

A number of circulating loops provide heating and cooling for the facility. The facility is mainly heated by one (1) low-grade heating loop (at 105°F) and one (1) medium-grade heating loop (at 135°F). There is a rink cooling loop (20°F) and a chilled water loop (45°C) serving the ice rink and air handling unit cooling loads respectively, and a geothermal field water loop provided heat source and sink to the facility as required throughout the year. There is also a heat recovery loop which can be open to any of the above-mentioned loops (low-grade loop, medium-grade loop, chilled water loop, geothermal field loop, and ice rink cooling loop) used to share energy within the facility.

The low-grade heating loop operates at 105°F and is supplied by the heat rejection of the ice plant and serves the in-floor heating and all the air handling unit heating coils except for the pool AHU-3. If the heat rejected by the ice plant is greater than the demand for AHU heating and in-floor heating, the excess heat from the low-grade loop is rejected first to the heat recovery loop and as second stage to a cooling tower. If additional heat is required for the


SEPTEMBER 2020

low-grade loop when the ice rink is satisfied, the ice plant can operate to transfer heat from the heat recovery loop to the low-grade loop. Due to the intermittent operation of the ice plant, the low-grade loop constantly switches from having to reject heat to the heat recovery loop and to the cooling tower and from requiring additional heat from the heat recovery loop. The lack of water volume storage for the low-grade loop prevents the ice plant and the low-grade loop from operating in unison based on steady load demand.

The medium-grade heating loop operates at 135°F and is heated by the condenser heat rejection of a Multistack chiller which simultaneously provides cooling to the chilled water loop which operates at 45°C. The Multistack chiller operates between a chilled water buffer tank and a medium-grade buffer tank. The medium-grade heating loop provides heating for the pool water heating (all three pools), the perimeter radiator heaters, the pool AHU-3 heating coil and also provides domestic hot water preheat for the Zamboni water and main domestic hot water systems. The Multistack operate to maintain the loop requiring the most demand between the chilled water and medium-grade loops. If excess heat is supplied to the medium-grade loop, the excess heat is rejected to the heat recovery loop and if additional heat is required for the chilled water loop, additional heat is provided by the heat recovery loop. An electric boiler is connected to the medium-grade heating loop for supplemental and backup heating capability, but according to the operational staff, the electric boiler does not require to operate often.

There is also a heat pump loop which connect directly to the heat recovery loop and supplies a number of distributed heat pumps that provide heating and cooling for the library and office areas of the facility. A geothermal field water loop is directly connected to the heat recovery loop and provides heat addition and rejection capability for the loop depending on the heating/cooling equilibrium of the facility. It was found that the geothermal loop operates almost continuously during the year and that the geothermal loop temperature is relatively high throughout the year suggesting that overall there is a yearly surplus of heat from the facility that continuously rejects to the geothermal field. As all the loops are openly interconnected via the heat recovery loop, all circulating loops utilize 40% ethylene glycol as a fluid medium. 40% ethylene glycol is required for freeze protection of the ice rink cooling loop and for the air handling units heating coils. The ice plant consists of a packaged CIMCO plant utilizing three (3) 40 ton capacity screw type compressors. The ice rink is controlled by an infra-red temperature sensor and the rink slab pump cycles as required to provide cooling for the ice pad. Zamboni uses 160°F hot water and requires on average 100 gallon of water per flood. The rink humidity is controlled by four (4) desiccant electric dehumidifiers.

The pool area is ventilated, dehumidified and heated by a mixed air rooftop unit (AHU-3). The AHU-3 has DX cooling to provide dehumidification and the excess heat from the dehumidification is used to heat the pools. Each pool has a filter pump that operates continuously to provide water filtration and chemical treatment. A rooftop solar water heater provides preheating for the lap pool. Ventilation for the rest of the facility (other than the pool area) is provided by five (5) rooftop air handling units. AHU-1 is a mixed air unit providing heating and cooling to the lobby area of the building, AHU-2 is a 100% outside air unit with heat recovery providing ventilation to the pool change rooms, AHU-3 serves the pool as described above, AHU-4 and AHU-5 are 100% outside air units with heat recovery providing ventilation to the ice rink and rink changing rooms.

2.0 SERVICE REQUIREMENTS

2.1 PROJECT SCOPE

The detailed energy audit outlined six measures to conserve water, energy and improve operations. For the measures listed below, the proponents will work with the general manage of the LCLC to ensure the final design details meet the operational needs of the facility. The proponent will prepare a detailed design in line with the

energy saving outlined in the energy audit. Following that, the proponent will create tender documents for the LCLC to review and post. The Proponent will provide Engineering Services throughout the build phase for each of the following measures.

2.1.1 GROUND LOOP FLUID REPLACEMENT AND ISOLATION Scope of work

The facility uses a number of separate water loops to provide heating and cooling for the building and its process loads including two separate cooling loops for the ice pad and AHU cooling coils, two heating loops for the in-floor heating, AHU heating coils and DHW and pool water heating, one heat recovery loop which can tie in to any of the above-mentioned loops and a geothermal field loop. As all the circulating loops are directly interconnected, the fluid medium are currently the same for all loops and satisfy the most critical freezing protection scenarios of any of the loops. The current fluid medium for the circulation loops is a mixture of 40% ethylene glycol which provides freeze protection down to -23°C (-10°F) which can be encountered at the AHU coils during extreme cold days.

For this measure the consultant will design, tender and project manage work as required to :

1) isolate this loop from the remainder of the building and replace the existing hydraulic separator;

2) serve the geothermal loop with a new heat exchanger that will act to isolate the geothermal loop fluid from the rest of the building loops. Ethylene Glycol will be removed and a new fluid medium for the geothermal loop consisting of 25% propylene glycol will be put in its place.

The addition of the new heat exchanger will result in additional pressure drop for the heat recovery loop and the geothermal loop, however this increase in pressure drop will be mitigated for the geothermal loop as the 25% propylene glycol solution has better heat transfer properties and lower viscosity which will generate pumping savings for the geothermal loop.

3) As part of this measure, new variable speed drives will be installed on the geothermal pumps to balance the system and allow variable flow through the geothermal loop to meet demand from the system while generating pumping energy savings.

2.1.2 ICE PLANT OPTIMIZATION AND HOT WATER STORAGE TANK Detailed Scope of Work

The facility uses a number of separate water loops to provide heating and cooling for the building and its process loads including two separate cooling loops for the ice pad and AHU cooling coils, two heating loops for the in-floor heating, AHU heating coils and DHW and pool water heating, one heat recovery loop which can tie in to any of the above-mentioned loops and a geothermal field loop.

The ice plant operates primarily to satisfy the ice pad cooling load and is currently controlled via an infrared temperature sensor monitoring the surface temperature of the ice. Upon a signal from the infrared sensor during resurfacing of the ice, the plant operates at high capacity to freeze the ice as quickly as possible until the ice surface temperature returns to setpoint. During this high capacity operation, large amount of heat is rejected to the low-grade loop which serve the in-floor and AHU heating. This energy rejected in most times surpasses the heating


SEPTEMBER 2020

capacity of the low-grade loop, thus excess heat is rejected to the geothermal field and through the cooling tower. Once the ice plant turns off when the ice temperature is satisfied, the low-grade heating loop loses all heating sources. To serve the heating low-grade loop when the ice pad does not require cooling, the ice plant is required to operate to ‘cool’ the geothermal loop thus providing heating to the low-grade loop. This imbalance in cooling and heating loads between the ice rink and the low-grade loop and the lack direct storage water volume on the low-grade heating loop results in additional energy use resulting from having to constantly transfer energy to and from the geothermal loop via the ice plant compressors.

Based on the annual energy use of the ice plant, there is constantly an annual surplus of heat available from the ice plant heat rejection to more than satisfy the heating load of the low-grade loop.

For this measure the consultant will design, tender and project manage work required to:

a) install a new storage tank on the low-grade loop sized to store all the heat rejection of the ice plant during a resurfacing cycle in order to use the energy directly by the low-grade loop once the ice plant shuts off. This would prevent the ice plant from having to constantly operate open to the geothermal loop in order to satisfy the heating demand of the low-grade loop. The new storage tank would have to be between 6,000 to 8,000 gallons in water volume capacity in order to store the entire heat rejection of the ice plant during an ice resurfacing cycle. The new storage tank would be insulated and installed outside by the existing cooling tower.

2.1.3 HEATING LOOPS PIPING MODIFICATIONS AND MERGING Detailed Scope of Work

Currently, there are two (2) separate heating loops serving the facility. There is the low-grade heating loop which is served by heat rejection of the ice plant and serves the air handling units heating and in-floor heating and operates at 105°F. There is also the medium-grade heating loop which is served by the Multistack chiller and serves pool heating, DHW preheat and perimeter heating and operates at 135°F. Currently, energy sharing between the two loops is only achievable through the geothermal loop system. There is continuously excess heat being rejected from the low-grade loop to the geothermal field, and simultaneously, the Multistack constantly operates to provide heat to the medium-grade loop via the geothermal field. This simultaneous heat rejection and extraction from the geothermal field through pumping and compressor energy of the chillers and ice plant results in additional energy.

In this measure the consultant will:

1. Design, tender and project manage the work required to : merge the two heating loops together to be able to take advantage of energy sharing directly between the two loops without the use of the geothermal field and Multistack chiller.

2. Convert the 135°F loop to 105°F and then directly connect the two low-grade loops. This would minimize the use of the geothermal field and thus the use of the Multistack chiller. The Multistack chiller would then primarily be used to provide cooling for the chilled water loops and occasionally some heat to the low-grade loop only during peak heating periods.

This measure would include the replacement of the AHU-3 heating coil, and the pool water heating heat exchangers to operate at 105°F at design condition.

2.1.4 AHU COILS FLUID REPLACEMENT AND ISOLATION Detailed Scope of Work

The facility uses a number of separate water loops to provide heating and cooling for the building and its process loads including two separate cooling loops for the ice pad and AHU cooling coils, two heating loops for the in-floor heating, AHU heating coils and DHW and pool water heating, one heat recovery loop which can tie in to any of the above-mentioned loops and a geothermal field loop. As all the circulating loops are directly interconnected, the fluid medium are currently the same for all loops and satisfy the most critical freezing protection scenarios of any of the loops. The current fluid medium for the circulation loops is a mixture of 40% ethylene glycol which provides freeze protection down to -23°C (-10°F) which can be encountered at the AHU coils during extreme cold days.

After the implementation of measure 2.1.1- Ground Loop Fluid Replacement and Isolation, the geothermal field would be isolated from the rest of the building loops. After the implementation of measure 2.1.2 - Ice Plant Optimization and Storage tank, the ice pad cooling loop can be isolated from the heat recovery loop as the ice plant would not require to ‘cool’ the geothermal loop to provide heat to the low-grade loop. As such, having the geothermal loop and the ice pad cooling loops isolated from the rest of the circulation loops, the only freeze protection remaining would be the water going to the AHU coils.

For this measure the consultant will design, tender and project management work required to :

1) isolate the AHU coil water from the remainder of the building by installing new heat exchangers for each AHU coil and new coil circulation pumps. The AHU coil loops would utilize a solution of 40% propylene glycol to provide freeze protection and the rest of the building loops (both heating loops, the heat recovery loop and the chilled water loop) can now utilize water as the fluid medium. Using water instead of the existing 40% ethylene glycol for the building loops will result in significant pumping energy savings as water has far superior heat transfer properties and lower viscosity than ethylene glycol.

2.1.5 HIGH GRADE HEAT PUMP FOR DHW AND THERAPY POOL Detailed Scope of Work

After implementation of measure 2.1.3 -Heating Loops Piping Modifications and Merging, all heating loops would operate at 105°F which would not be hot enough to provide for the heating of the domestic hot water and of the Therapy Pool. These heating loads would have to be provided by electric DHW tanks and electric boiler respectively.

In this measure the consultant will design, tender for and project manage the installation of a new high grade heat pump that would operate to produce 160°F water from the 105°F loop which would serve the high grade loads of the building including the DHW heating and the Therapy pool heating. The new heat pump would operate at a coefficient of performance (COP) of 4 which would be four times more efficient than electric elements.

2.1.6 Building Automation System (BAS) OPTIMIZATION AND ANALYTICS Detailed Scope of Work

Currently the facility is controlled by a combination of a Cimco Direct Digital Control system controlling the ice plant and a Building Automation System (BAS) controlling the space heating, air handlers and heating and cooling pumps. The pool dehumidifiers have stand-alone digital controls.

The consultant will re-commission some of the sequences to implement enhanced energy saving strategies with the


SEPTEMBER 2020

9

existing Direct Digital Control systems. The strategy and changes proposed include:

• Enhanced time of day scheduling for air handlers. • Re-commissioning of critical control devices including CO2 sensors, pressure sensors, damper actuators, etc. • Temperature reset based on demand for the chilled water and hot water loops.

• Ice temperature reset based on activity level. The retrofit opportunity will require an automated method of identifying whether the BAS is consistently controlling the systems optimally or per design conditions once the site is retrofitted for a seasonal changeover. The goal will be to optimally utilize the infrastructure and setup rules to ensure continued operation and optimization over the life of the assets.

Analytics solutions will provide for optimal resets to occur to achieve the energy savings as outlined and also notify the staff in the event the systems are not reacting as expected given the conditions.

2.1.7 MEASUREMENT AND VERIFICATION METHODOLOGY

The consultant will be required to submit a Measurement and Verification Plan which shall adhere to Efficiency Nova Scotia (ENS) custom program requirements and the International Performance Measurement and Verification Protocol. The following is shown for reference and verification purposes. The contractor is expected to verify the savings shown below in their modelling prior to installation. The savings will be verified during the commissioning phase of this project.

1 BUILDING SUMMARY

The purpose of this feasibility study is to identify and analyze energy efficiency and conservation

opportunities, which could result in energy savings for the facility. There is potential to improve

energy efficiency through upgrades and integrating technology advancements in the following areas:

• Energy efficient lighting technology;

• System Re-piping & Energy Sharing Optimization;

• Controls Optimization; and

• Variable Flow Pumping Technology.

To improve the facility’s operation and performance, energy conservation opportunities have been

identified that will reduce energy consumption and demand. An overall summary of the building’s

energy usage and proposed energy program is summarized in Table 1.1 – Building Energy Usage and

Savings Summary. A more detailed summary of the savings opportunities for all energy conservation

measures is presented in Table 1.2 – Energy Conservation Measure Summary. Section 5 – Energy

Efficiency and Conservation Measures summarizes the recommended improvements that have been

identified for Lunenburg County Lifestyle Centre.

The energy savings associated with the recommended program represent an 18.1% reduction in

annual energy consumption from the existing usage. The program has the benefit of reducing the

facility’s average energy intensity from 33.8 ekWh/ft²/year to 27.7 ekWh/ft²/year and the utility cost

intensity from $4.90 per ft²/year to $4.12 per ft²/year. Implementation of the proposed program will

eliminate 460 tonnes of eCO2 per year which is an 18.1% greenhouse gas emissions reduction.

ENERGY AUDIT REPORT


2 BACKGROUND AND METHODOLOGY

2.1 OBJECTIVES

The objective of this ASHRAE Level II energy audit was to provide the Lunenburg County Lifestyle

Centre with a comprehensive plan to outline, evaluate, and report on the following:

• The current state of energy usage within the audited facility;

• Opportunities for “Greenhouse Gas Reductions”;

• Measures for improving energy efficiency and conservation;

• Measures for reducing the cost of energy and providing equipment renewal;

• The financial impact of implementing the energy efficiency and conservation measures (ECM),

including capital cost and projected annual savings; and

• Provide guidelines for making future decisions related to capital investments and operational

changes which impact energy usage.

The project approach included preliminary planning sessions, meetings with key personnel identified

by the client, site work, and a full energy consumption analysis for the facilities. Our methodology

included continuous communications with key client contacts. The process explained in subsequent

sections was followed to ensure a systematic and comprehensive approach to the project.

2.2 ENERGY AUDIT AND ANALYSIS METHODOLOGY

In order for audit results to be both meaningful and reliable, a strategic approach was taken. All

energy consuming systems were evaluated in conjunction with the intended use of the building. The

proposed measures bring value from both an energy reduction and a building operation standpoint.

The purpose of the energy audit is to identify current condition of the facility, building equipment,

mechanical and electrical systems, and the potential improvements that would result in energy and

energy cost savings. The facility’s equipment and systems were reviewed to evaluate and confirm

current conditions, remaining useful life, operating profiles, efficiencies, methods of control and the

quality of maintenance.

Site Visits and Interviews

A site visit was carried out on May 27, 2020 to review the building systems. Interviews were

conducted with building operation and maintenance staff to obtain an understanding of the building

systems operations, occupancy patterns, existing problems, past upgrades and renovations and

energy challenges. Building drawings, maintenance manuals and energy consumption information

were collected.


ENERGY AUDIT REPORT


Lighting Audit and Analysis

The purpose of the lighting study is to conduct an audit of the existing lighting systems and its

controls, to evaluate the potential savings opportunities and to report the recommended lighting

retrofits or replacement for the facility. The audit process included a general walk through of the

buildings. An inventory of the current lighting systems of each room was documented and factors

such as the type and quantity of the lighting system installed, their hours of operation and the level

of lighting they provided in the area they serve were noted. The analysis of the lighting systems

consisted of entering the inventory into a database where possible measures were determined.

Note that a full lighting audit has not been completed for the facility and lighting consumption and

potential savings were approximated based on a lighting fixture count from the original

construction drawings and compared to similar facilities. It is recommended that a detailed lighting

study be completed and measure savings updated prior to implementing any lighting upgrades.

Mechanical Audit and Analysis

The purpose of the mechanical study is to conduct an audit of the existing mechanical systems and

its operations, to evaluate the potential savings opportunities and to report the recommended

mechanical improvements for the facility. The mechanical audit consists of an on-site review of the

buildings and key process equipment, mechanical and electrical system components.

The audit process included the collection of information such as equipment schedules, condition and

control settings. An inventory of the major electrical and mechanical systems was documented.

Operational review of the existing energy management control system (EMCS) was used to provide

insight into how systems operated. The analysis of the mechanical systems consisted of entering the

gathered data into an energy modeling program where possible measures were determined.

Note that at the time of the audit, most equipment were not operational including the ice plant as

the ice was removed and two of the three pools were drained for yearly cleaning. As such, a number

of assumptions were applied to model the operation of the building when fully operational. It is

recommended to revisit the site to gather operational information once the ice plant is in use and

to make any adjustments to the energy model accordingly prior to implementing any upgrades as

outlined in this report.

Energy Analysis Methodology

Energy modeling provides a thorough review and evaluation of the energy use profiles of the facility.

This analysis established a baseline of energy consumption from which savings were measured and

serves as a guide to investigate certain building systems and operations exhibiting energy saving

potential.

The energy analyses were carried out based on the gathering of building equipment data and

information on the hours of operation for all building equipment through system schedules,

discussion with building operators and site observations. The energy consumption for each system

was calculated and the breakdown of the energy consumption and demand was determined.


ENERGY AUDIT REPORT


Once the model is reconciled with the actual energy consumption, the total energy use is broken

down into the relative proportion of the overall use for each main system. The energy use analysis is

conducted to summarize the total energy use and cost and is used to assist in the identification of the

measures.

For most projects, the value used for energy consumption analysis is the Energy Utilization Index

(EUI), an industry approved method of estimating energy consumption for all fuel sources. The EUI

represents the equivalent kilowatt hours/per square feet (ekWh/ft2). The EUI helps to understand

how the facility is consuming energy, as well as an indicator of the potential for energy savings for the

future.

Measure Selection Criteria

Once the energy analysis and reconciliation was completed, Energy Conservation Measures (ECMs)

were developed on the basis of looking at each of the energy consuming systems and, in conjunction

with the information gathered on how the facility is used, determining the most energy efficient way

of operating the facility.

As well as the obvious choices of either replacing or retrofitting inefficient equipment, the impact of

each ECM on the operation of the facilities, its maintenance programs, applicability and

constructability was considered.

Measures proposed for implementation on this project were selected based on the viability of the

measure against the following criteria:

• costs and savings within overall payback;

• condition of existing systems and requirements for short term equipment renewal;

• cost to retrofit the existing system compared to the cost to replace the system;

• overall impact on occupants and general acceptance of changes; and

• equipment approval by facilities personnel.

Cost Estimation Methodology

Costs were determined from data from previous projects, not theoretical pricing. In some

circumstances, the measures were reviewed with equipment suppliers before finalizing our cost

estimates. It is our intent to provide accurate pricing; however, the pricing provided should be used

as budgets only and not fixed prices. Pricing summary tables does include professional fee budgets

for engineering and construction management.

Savings Methodology

The savings for lighting and mechanical measures were calculated by customized spreadsheets and

databases wherein existing and proposed energy use can be tabulated. Savings estimates are based

on engineering calculations.


ENERGY AUDIT REPORT


Cost / Benefit Analysis

Retrofit alternatives were evaluated and measures were selected to yield a positive net present value.

Measures were evaluated on simple payback, return on investment and net present value. More

3 BUILDING AND SYSTEMS DESCRIPTION

3.1 GENERAL FACILITY DESCRIPTION

Facility Name: Lunenburg County Lifestyle

Centre

Facility Location: 135 N Park Street

Bridgewater, NS

Building Type: Multi-Purpose Recreation &

Cultural Centre

The Lunenburg County Lifestyle Centre is a multi-purpose facility opened in 2013. The sport,

recreation, and community facility houses an NHL-size arena (Clearwater Seafoods Arena) with a

capacity to seat 1,200 spectators; an aquatic centre (BMO Financial Group Aquatic Centre) suited to

both leisure and competitive users; a therapeutic pool; and a public library. Other multi-purpose

spaces include administrative offices, community and cultural spaces, and areas capable of hosting

meeting, exercise classes, senior citizens’ activities, and many other functions.

The address of the facility is 135 N Park Street, Bridgewater, Nova Scotia.

The exterior of the building consists of metal cladding walls with a built-up roof. Estimated insulation

values of R-12 and R-25 have been attributed to the walls and roof respectively. The windows are

aluminum frame double pane glass type with an estimated insulation value of R-2.5.

The facility is mostly occupied from 6 am to 10 pm Monday to Sunday.

Lighting Systems Description

The Lunenburg County Lifestyle Centre is currently utilizing mostly a combination of T8 fluorescent

lighting complete with electronic ballasts.

The lighting levels in most of the above areas were reported as being adequate by facilities staff. In

general, the original luminaires in this facility are nearing 6 years old and are in relatively good

condition.

The high bay luminaires that are presently illuminating the arena ice surface are T8 technology. These

luminaires have switching abilities.

More details on the lighting systems can be found in Appendix A – Lighting Retrofit Summary Sheet.

Mechanical Systems

A number of circulating loops provide heating and cooling for the facility. The facility is mainly heated

by one (1) low-grade heating loop (at 105°F) and one (1) medium-grade heating loop (at 135°F). There

is a rink cooling loop (20°F) and a chilled water loop (45°C) serving the ice rink and air handling unit

cooling loads respectively, and a geothermal field water loop provided heat source and sink to the

facility as required throughout the year. There is also a heat recovery loop which can be open to any

of the above-mentioned loops (low-grade loop, medium-grade loop, chilled water loop, geothermal

field loop, and ice rink cooling loop) used to share energy within the facility.

The low-grade heating loop operates at 105°F and is supplied by the heat rejection of the ice plant

and serves the in-floor heating and all the air handling unit heating coils except for the pool AHU-3. If

the heat rejected by the ice plant is greater than the demand for AHU heating and in-floor heating,

the excess heat from the low-grade loop is rejected first to the heat recovery loop and as second stage

to a cooling tower. If additional heat is required for the low-grade loop when the ice rink is satisfied,

the ice plant can operate to transfer heat from the heat recovery loop to the low-grade loop. Due to

the intermittent operation of the ice plant, the low-grade loop constantly switches from having to

reject heat to the heat recovery loop and to the cooling tower and from requiring additional heat

from the heat recovery loop. The lack of water volume storage for the low-grade loop prevents the

ice plant and the low-grade loop from operating in unison based on steady load demand.

The medium-grade heating loop operates at 135°F and is heated by the condenser heat rejection of

a Multistack chiller which simultaneously provides cooling to the chilled water loop which operates

at 45°C. The Multistack chiller operates between a chilled water buffer tank and a medium-grade

buffer tank. The medium-grade heating loop provides heating for the pool water heating (all three

pools), the perimeter radiator heaters, the pool AHU-3 heating coil and also provides domestic hot

water preheat for the Zamboni water and main domestic hot water systems. The Multistack operate

to maintain the loop requiring the most demand between the chilled water and medium-grade loops.

If excess heat is supplied to the medium-grade loop, the excess heat is rejected to the heat recovery

loop and if additional heat is required for the chilled water loop, additional heat is provided by the

heat recovery loop. An electric boiler is connected to the medium-grade heating loop for

supplemental and backup heating capability, but according to the operational staff, the electric boiler

does not require to operate often.

There is also a heat pump loop which connect directly to the heat recovery loop and supplies a

number of distributed heat pumps that provide heating and cooling for the library and office areas of

the facility. A geothermal field water loop is directly connected to the heat recovery loop and provides

heat addition and rejection capability for the loop depending on the heating/cooling equilibrium of

the facility. It was found that the geothermal loop operates almost continuously during the year and

that the geothermal loop temperature is relatively high throughout the year suggesting that overall

there is a yearly surplus of heat from the facility that continuously rejects to the geothermal field.

As all the loops are openly interconnected via the heat recovery loop, all circulating loops utilize 40%

ethylene glycol as a fluid medium. 40% ethylene glycol is required for freeze protection of the ice rink

cooling loop and for the air handling units heating coils.


ENERGY AUDIT REPORT


The ice plant consist of a packaged CIMCO plant utilizing three (3) 40 ton capacity screw type

compressors. The ice rink is controlled by an infra-red temperature sensor and the rink slab pump

cycles as required to provide cooling for the ice pad. Zamboni uses 160°F hot water and requires on

average 100 gallon of water per flood. The rink humidity is controlled by four (4) desiccant electric

dehumidifiers.

The pool area is ventilated, dehumidified and heated by a mixed air rooftop unit (AHU-3). The AHU-3

has DX cooling to provide dehumidification and the excess heat from the dehumidification is used to

heat the pools. Each pool has a filter pump that operates continuously to provide water filtration and

chemical treatment. A rooftop solar water heater provides preheating for the lap pool.

Ventilation for the rest of the facility (other than the pool area) is provided by five (5) rooftop air

handling units. AHU-1 is a mixed air unit providing heating and cooling to the lobby area of the

building, AHU-2 is a 100% outside air unit with heat recovery providing ventilation to the pool change

rooms, AHU-3 serves the pool as described above, AHU-4 and AHU-5 are 100% outside air units with

heat recovery providing ventilation to the ice rink and rink changing rooms.

Controls Systems

Most of the buildings ventilation, heating and cooling systems are controlled by a modern building

automation system. The CIMCO ice plant and the pool dehumidifier are controlled each by their

individual stand-alone controller.

Domestic Water System

Domestic hot water is provided by a combination of preheat tanks from the medium-grade loop, and

electric tank heaters. The washrooms generally uses low flow fixtures.

4 UTILITY USE AND COST SUMMARY

4.1 ENERGY CONSUMPTION

MCW Maricor was provided with utility data from the client. The data was compiled and entered into

an energy accounting database in order to conduct a utility bill analysis. The analysis is based on the

most representative year, selected from the data received. Energy usage was analyzed for the

following periods:

• Electricity: January 2016 to December 2018

• Water: January 2016 to December 2017

The following figures illustrate the monthly profiles for the representative utility usages. The yearly

profiles and monthly consumption summaries are found in Appendix B – Energy Utility Data.

Figure 4.1.1 – Electrical Consumption Profile

The above electrical consumption profile shows no correlation with the heating degree day (HDD)

profile which is typical for this type of building as the major energy usage of the building (pool and

rink energy) are not affected much by the exterior environment. Throughout the summer months

(June and August), the consumption is reduced due to the removal of the ice and subsequent shut off

of the ice plant.

5.2 SHORT TERM MEASURES (IN)

5.2.1 ECM A01: LIGHTING RETROFITS

Detailed Scope of Work

The Lunenburg County Lifestyle Centre is currently using a variety of fluorescent luminaires complete

with T8 lamps and electronic ballasts for their main source of interior lighting.

The luminaires within this complex were found to be rather new and in very good condition. It is

recommended that the complex go through a re-lamp and re-ballast of these fixtures. This measure

would include re-lamping with new 15 watt LED tubes and low ballast factor electronic ballast.

The high bay luminaires that are presently illuminating the arena ice surface are T8 technology. These

luminaires have switching abilities.

It is recommended that the existing T8 luminaire technology in the arena, illuminating the ice surface,

be replaced with new high bay LED luminaires. This measure will lower the power requirement within

the space and will hold the existing light level on the playing surface. With this new LED system we

recommend a new controller for the arena lighting, which will have the ability to set light levels for

different activities on the ice surface. It is recommended that this new controller be located in a more

convenient location than the existing system as discussed with the operations staff. Energy savings

will be realized by giving the operators the ability to control this system from a much more convenient

location.

Note that a full lighting audit has not been completed for the facility and lighting consumption and

potential savings were approximated based on a lighting fixture count from the original

construction drawings and compared to similar facilities. It is recommended that a detailed lighting

study be completed and measure savings updated prior to implementing any lighting upgrades.

Impact on Maintenance

Although it is difficult to put an actual number in place for maintenance savings, there will be a certain

degree of maintenance savings by applying these measures. With the guarantees from the

manufacturers on the application of new linear fluorescent lamps, as well as the long life expectancy

of new LED technology, the measures will represent an estimated annual maintenance savings of

several days.

The proposed retrofit will have the short term benefit of delaying the need for replacement of lamps

and ballasts. Because LED’s lumen output depreciates over time rather than instant failures, the

facility can choose to embark on a group re-lamping program in the future, where all lamps in a

section of the building are changed, once typical lumen output has depreciated to ~70% original

output; this is a common industry practice.


ENERGY AUDIT REPORT


Expected Service Life of Measure

From the time the work has been performed the new LED tubes and electronic ballasts come with a

six year manufacturer’s guarantee and the new luminaires have a warranty of five years with a life

expectancy of 20 years.

Assumptions & Calculations

The following assumptions were applied:

• Estimates for hours based on talks with building staff.

• Pre and post wattages used gathered from fixture manufacturers.

Heating penalty and cooling credit are calculated using engineering calculation spreadsheets.

5.2.2 ECM B01: GROUND LOOP FLUID REPLACEMENT AND ISOLATION


The facility uses a number of separate water loops to provide heating and cooling for the building and

its process loads including two separate cooling loops for the ice pad and AHU cooling coils, two

heating loops for the in-floor heating, AHU heating coils and DHW and pool water heating, one heat

recovery loop which can tie in to any of the above-mentioned loops and a geothermal field loop. As

all the circulating loops are directly interconnected, the fluid medium are currently the same for all

loops and satisfy the most critical freezing protection scenarios of any of the loops. The current fluid

medium for the circulation loops is a mixture of 40% ethylene glycol which provides freeze protection

down to -23°C (-10°F) which can be encountered at the AHU coils during extreme cold days.

Ethylene glycol typically is not used for geothermal loop application as it is poisonous and pose a risk

to the underground water aquifers in the event of leaks, etc. The CSA C448 item 5.7.1.1.2 specifically

states that: “Potassium acetate or ethylene glycol shall not be used within heat transfer fluid solutions

in ground source heat pumps systems”. Acceptable anti-freeze fluids include ethanol, propylene

glycol, and methanol solutions.

In order to comply with the local codes and standards and to reduce the environmental risk associated

with the use of ethylene glycol solutions for the geothermal field loop, it is recommended to isolate

this loop from the remainder of the building and to use an acceptable anti-freeze solutions for the

geothermal loop. It is proposed to replace the existing hydraulic separator 2 serving the geothermal

loop with a new heat exchanger that will act to isolate the geothermal loop fluid from the rest of the

building loops. It is proposed to use a new fluid medium for the geothermal loop consisting of 25%

propylene glycol, which would provide freeze protection down to -6°C (21°F) which is suitable for

geothermal applications. The addition of the new heat exchanger will result in additional pressure

drop for the heat recovery loop and the geothermal loop, however this increase in pressure drop will

be mitigated for the geothermal loop as the 25% propylene glycol solution has better heat transfer

properties and lower viscosity which will generate pumping savings for the geothermal loop. As part

of this measure, new variable speed drives will be installed on the geothermal pumps to balance the

system and allow variable flow through the geothermal loop to meet demand from the system while

generating pumping energy savings.


The addition of a second type of glycol anti-freeze will add to the maintenance and result in additional

stored products.

5.2.3 ECM B02: ICE PLANT OPTIMIZATION AND HOT WATER STORAGE TANK





recovery loop which can tie in to any of the above-mentioned loops and a geothermal field loop.

The ice plant operates primarily to satisfy the ice pad cooling load and is currently controlled via an

infrared temperature sensor monitoring the surface temperature of the ice. Upon a signal from the

infrared sensor during resurfacing of the ice, the plant operates at high capacity to freeze the ice as

quickly as possible until the ice surface temperature returns to setpoint. During this high capacity

operation, large amount of heat is rejected to the low-grade loop which serve the in-floor and AHU

heating. This energy rejected in most times surpasses the heating capacity of the low-grade loop, thus

excess heat is rejected to the geothermal field and through the cooling tower. Once the ice plant turns

off when the ice temperature is satisfied, the low-grade heating loop loses all heating sources. To

serve the heating low-grade loop when the ice pad does not require cooling, the ice plant is required

to operate to ‘cool’ the geothermal loop thus providing heating to the low-grade loop. This imbalance

in cooling and heating loads between the ice rink and the low-grade loop and the lack direct storage

water volume on the low-grade heating loop results in additional energy use resulting from having to

constantly transfer energy to and from the geothermal loop via the ice plant compressors.

Based on the annual energy use of the ice plant, there is constantly an annual surplus of heat available

from the ice plant heat rejection to more than satisfy the heating load of the low-grade loop. It is

proposed to install a new storage tank on the low-grade loop sized to store all the heat rejection of

the ice plant during a resurfacing cycle in order to use the energy directly by the low-grade loop once

the ice plant shuts off. This would prevent the ice plant from having to constantly operate open to

the geothermal loop in order to satisfy the heating demand of the low-grade loop. The new storage

tank would have to be between 6,000 to 8,000 gallons in water volume capacity in order to store the

entire heat rejection of the ice plant during an ice resurfacing cycle. The new storage tank would be

insulated and installed outside by the existing cooling tower.


The addition of a storage tank will have marginal impact on the maintenance of the facility.

5.2.4 ECM B03: HEATING LOOPS PIPING MODIFICATIONS AND MERGING


Currently, there are two (2) separate heating loops serving the facility. There is the low-grade heating

loop which is served by heat rejection of the ice plant and serves the air handling units heating and

in-floor heating and operates at 105°F. There is also the medium-grade heating loop which is served

by the Multistack chiller and serves pool heating, DHW preheat and perimeter heating and operates

at 135°F. Currently, energy sharing between the two loops in only achievable through the geothermal

loop system. Currently, there is continuously excess heat rejected from the low-grade loop to the

geothermal field, and simultaneously, the Multistack constantly operates to provide heat tot the

medium-grade loop via the geothermal field. This simultaneous heat rejection and extraction from

the geothermal field through pumping and compressor energy of the chillers and ice plant results in

additional energy.

As such, it is proposed to merge the two heating loops together to be able to take advantage of energy

sharing directly between the two loops without the use of the geothermal field and Multistack chiller.

It is proposed to convert the 135°F loop to 105°F and then directly connect the two low-grade loops.

This would minimize the use of the geothermal field and thus the use of the Multistack chiller. The

Multistack chiller would then primarily be used to provide cooling for the chilled water loops and

occasionally some heat to the low-grade loop only during peak heating periods.

This measure would include the replacement of the AHU-3 heating coil, and the pool water heating

heat exchangers to operate at 105F at design condition.


The reduction in yearly runtime for the Multistack chiller and associated pumps will prolong the useful

life of the equipment and will have a maintenance benefit for the building.

medium for the circulation loops is a mixture of 40% ethylene glycol which provides freeze protection

down to -23°C (-10°F) which can be encountered at the AHU coils during extreme cold days.

After the implementation of measure B01 - Ground Loop Fluid Replacement and Isolation, the

geothermal field would be isolated from the rest of the building loops. After the implementation of

measure B02 – Ice Plant Optimization and Storage tank, the ice pad cooling loop can be isolated from

the heat recovery loop as the ice plant would not require to ‘cool’ the geothermal loop to provide

heat to the low-grade loop. As such, having the geothermal loop and the ice pad cooling loops isolated

from the rest of the circulation loops, the only freeze protection remaining would be the water going

to the AHU coils.

It is recommended to isolate the AHU coil water from the remainder of the building by installing new

heat exchangers for each AHU coil and new coil circulation pumps. The AHU coil loops would utilize a

solution of 40% propylene glycol to provide freeze protection and the rest of the building loops (both

heating loops, the heat recovery loop and the chilled water loop) can now utilize water as the fluid

medium. Using water instead of the existing 40% ethylene glycol for the building loops will result in

significant pumping energy savings as water has far superior heat transfer properties and lower

viscosity than ethylene glycol.

5.2.7 ECM C01: BAS OPTIMIZATION AND ANALYTICS


Currently the facility is controlled by a combination of a Cimco DDC system controlling the ice plant

and a Building Automation System (BAS) controlling the space heating, air handlers and heating and

cooling pumps. The pool dehumidifiers has stand-alone digital controls.

It is proposed re-commission some of the sequences and to implement enhanced energy saving

strategies with the existing DDC systems. The strategy and changes proposed include:

• Enhanced time of day scheduling for air handlers;

• Re-commissioning of critical control devices including CO2 sensors, pressure sensors, damper

actuators, etc.

• Temperature reset based on demand for the chilled water and hot water loops.

• Ice temperature reset based on activity level.

MCW believes this proposed retrofit opportunity will require an automated method of identifying

whether the BAS is consistently controlling the systems optimally or per design conditions once the

site is retrofitted for a seasonal changeover. The goal will be to optimally utilize the infrastructure

and setup rules to ensure continued operation and optimization over the life of the assets. The BAS

performance is reliant on Operators visually analysing performance on the graphics, or via trend logs

or automated alarms where programmed. Practically, this approach is limited by the time Operators

can dedicate to constantly monitor the graphics to find situations where the BAS cannot meet the

design requirements. Trend logs and triggered alarms programmed into the BAS are intended to catch

excursions, but without proper insight into what events lead to excursions the programming is

iterative and costly.

Analytics will allow for optimal resets to occur to achieve the energy savings as outlined and also

notify the staff in the event the systems are not reacting as expected given the conditions.

MCW proposes that this measure utilize a Building Performance Monitoring & Analytics system to

optimize and maintain performance of the opportunity. The recommendation is to utilize a new

Cooper Tree data analytic platform.

Data collection is achieved through a physical or virtual device, depending on the situation. Physical

data acquisition devices, can be connected locally to the BAS with manual or automated uploads.

Alternatively, a virtual device can be created and connected to the BAS. The data is uploaded to cloud-

based software platform, aggregated into a single database, and analyzed with algorithms.

The software will offer automated application of pre-defined smart rules to the BAS information

captured from site. MCW will create fault detection and diagnostic (FDD) algorithms from a library of

insights to capture excursions in operations by the BAS or building equipment. The advent of ‘big-

data’ storage and automation allows for visibility of the entire BAS and connected equipment.

Predicted faults (performance excursions) include:


ENERGY AUDIT REPORT


• Systems that are commanded to be disabled, but are showing status due to starters being in

hand.

• Ongoing drift associated with the operation of a motor, whether its current is deviating from

normal levels.

• Whether speed is changing as a function of expected load (potentially indicative of poor set-

point or sensor placement).

• System input values that have not changed over hours, based on COV reporting (indicative of

faulty sensors).

• Execution of calibration routines to assess whether the mixed air dampers are holding shut

through temperature monitoring during full recirculation morning warm-up.

• Assessment of leaking valves through the application of differential temperature

measurement while valves are closed.


Building analytics is a method of identifying long-term trends to optimize energy usage and

implement fault detection diagnostics. A Data Acquisition Device (DAD) pulls up to 5000 data points

from the BAS, such as AHU supply air temperature, building return water temperature or valve

position, every 15 minutes and stores it on an internal hard drive and if enabled, uploads it to a secure

server. At this point, the analytics engine process this data into actionable insights which deliver

critical information identifying energy and maintenance savings opportunities. Initially showing up as

trends, this data provides significant insight into how the BAS systems are operating.

This information is served to users in a series of dashboards, reports and alerts to help users take

charge of their building performance. This insight allows for an in-depth view of how the building

HVAC systems operate and clearly outlines inefficiencies and highlights opportunities for improved

performances.

5.3 LONG TERM MEASURES (OUT)

5.3.1 ECM B06: RINK DEHUMIDIFICATION UPGRADE


The arena seating area is equipped with 4 electric powered dehumidification units. These units are

set to maintain space conditions in the arena. The capacity of the installed units is significantly

deficient to provide the required dehumidification capacity for a fully occupied ice event in summer

design conditions.

It is proposed to install a new rink dehumidification unit to replace the four (4) existing electric

desiccant dehumidifiers. The new rink dehumidifier would provide the ventilation requirement for

the rink area, thus existing AHU-5 and AHU-6 air handlers would be re-balanced and re-duct to only

supply the change rooms Level 1 areas. The new dehumidification unit would have twice the

dehumidification capacity of the exiting dehumidifiers and would operate as a desiccant wheel,

however the new unit would utilize low-grade water from the existing 105°F loop for regeneration of

the desiccant wheel. There is currently an access of heat rejection from the plant that could be used

for regeneration.

Even though the new rink dehumidifier would be more efficient than the existing dehumidifiers, it

would still consume more energy than the existing system in order to properly dehumidify the space

and prevent fog build-up on the ice. This measure would have to be considered as an improvement

to the condition and comfort of the ice rink rather than an energy reducing measure.


The addition of a new rooftop rink dehumidifier to replace the existing four dehumidification will

result in an increase of maintenance requirement.


The new rink dehumidifier will have the capacity to properly dehumidify the rink area under a fully

occupied ice event even during the peak summer months.




Rink Desiccant Dehumidifier AHU: 25 years

Assumptions


• Existing Electric Desiccant dehumidification regeneration provided by electric coil at an

5.3.2 ECM D01: SOLAR PV INSTALLATION


There is currently no solar generation onsite. Roof space is available for the installation of solar

photovoltaic panels.

Photovoltaic (PV) is the conversion of light into electricity. Solar Photovoltaic modules (panels)

generate electricity from the sun’s rays. Inverters are used to convert the Direct Current (DC)

electricity generated by Solar PV panels into Alternating Current (AC) electricity. Two types of

inverters are available for installation and have been compared in this report:

• String inverter with Solaredge technology optimization system

• Enphase micro-inverter based system

In general, Solar PV panels offer the following benefits:

• Low maintenance

• Long lifecycle

• Visibility for public awareness

• Silent operation

• Sustainable performance maintained at 80% over the system’s lifecycle

In order to harvest solar energy, individual solar panels must be arranged in an array and strategically

oriented for maximum solar exposure. In order to angle the array of panels to maximize exposure,

they must be mounted on a stable, durable racking system of sound structural integrity in order to

withstand wind, hail and corrosion over decades. A structural stand will tilt the PV array at a fixed

angle to obtain the highest annual solar energy harvest. PV arrays can be installed in a variety of

locations as the racking system and stand can be engineered to accommodate many different types

of footing. The most typical installations are rooftop mounted and ground mounted.

It is also important to understand that renewable energy production does not always follow the

facility’s energy demands. During a sunny weekend, the on-site energy generation may exceed the

building energy requirements In the case of this hospital, 50 kW of PV would be utilized and directly

synced into the building.

6 CONCLUSION

As part of their initiative to reduce energy consumption and the environmental footprint, the

Lunenburg County Lifestyle Centre commissioned MCW Maricor to conduct an energy study of the

facility.

Having conducted a site review and analyzed the existing systems, energy efficiency and conservation

measures (ECM) were developed which, if implemented, will provide both consumption and financial

savings in addition to reducing the environmental footprint of the facility.

The more attractive ECMs proposed result in an energy performance improvement project requiring

a capital investment of $1,024,248 and will reduce annual energy consumption by 574,524 kWh of

electricity consumption and 740 kW of electrical demand. This represents a financial savings of

$72,676 (based on current energy pricing) and a payback of 14.1 years, not including any incentives

and carbon reduction credits. It is our opinion that these measures be pursued in order to reduce

energy consumption and improve the overall performance of the facility.

Like many building owners and managers, the Lunenburg County Lifestyle Centre must now include

energy efficiency and conservation in the equation when making decisions on facility renewal and

operation. The implementation of this report should be considered as a stepping-stone towards a

continued focus on reducing energy consumption. This opportunity will allow the Lunenburg County

Lifestyle Centre to reap the financial and operational benefits of improved energy performance while

demonstrating leadership in environmental responsibility.
