o Reliability o Sustainability o Responsibility

Energy efficiency can increase profitability through lower costs and consumption. Traditional corporate realism, defined through the bottom line, provides a compelling case for efficiency.

HOTEL ENERGY EFFICIENCY Value Proposition

4

Hotel energy efficiency - the nexus of realism and altruism

SourceOne A Veolia Energy Company

In the hotel industry there is added incentive for energy efficiency. Increasingly educated consumers expect it. Corporate purpose and values are increasingly central to attracting and motivating employees, customers, and partners. Corporate realism is beginning to merge with altruism.

Sustainability is responsibility

Effective energy efficiency requires planning. Understand your budget and your goals. Smart resource planning can result in smart energy.

Planning is key


5

Energy Efficiency offers the best opportunity to save


Energy efficiency is the most effective way to address cost and consumption.

Savings 10% to 30%

Energy Efficiency 5% to 15%

Energy Procurement 1% to 5%

Tariff Analysis 1% to 3%

Utility Bill Payment 1% to 2%

Utility Bill Auditing 1% to 3%

Utility Bill Processing and Reporting 1% to 2%

What is the process?

HOTEL ENERGY EFFICIENCY Data

7

Meters provide data

Meters capture the data

Data is shared with end users

Users manage usage and cost


Energy is consumed

Better understanding means better management

Better data lays the groundwork for better monitoring and verification

HOTEL ENERGY EFFICIENCY Data


Understanding where you are is the first step to planning where you go

ASHRAE Level 1: Preliminary Audit A high level walkthrough assessment that provides a big picture of energy options.

HOTEL ENERGY EFFICIENCY Understanding and Insight

9

Determine the level of engagement


Crawl Walk Run

ASHRAE Level 2: Energy Survey and Analysis An in-depth assessment that digs deeper into proposed equipment and operational improvements and their potential savings and cost.

ASHRAE Level 3: Investment Grade Audit Detailed assessment of specific recommendations that will require significant investments of capital, personnel, or limited resources.

Understand your budget and your goals Do you know where you are?


10

Different levels of Energy Conservation Measures (ECMs)


Quick Payback

• Easy to implement • Examples: LED lighting, motor change-outs, building

envelope, plug load controllers, aerators, BAS optimization, T-stats etc.

Moderate Payback

• Require significant engineering and capital • Examples: BAS installation, VFD’s, chillers, boilers,

fan coil units, CHP plants, etc.

Long Payback

• Facility Improvement Measure (FIM) with little to no energy savings and payback

• Windows, elevators, roof replacement, energy management systems, etc.


11

ECMs are recommended



12

ECMs – Quick Payback


ECM Savings Cost Payback

Lighting Fixture Alteration $10,000 $18,000 1.8

Manually Stage Pumps 12-1 and 12-2 $11,974 $0 0


13

ECMs – Medium Payback



VFDs on (2) Primary CHW Pumps $6,200 $43,840 7.1

TAB & Repair AHU 3 hot/cold deck $2,358 $12,400 5.3


14

ECMs – Long Payback



Calibrate/Replace Temp & press Sensors $360 $6,820 18.9

Install Cooling Coil $1,004 $17,950 17.9


15

Example #1: Building Automation Systems


Benefits o Demand Based Control

Efficiency Maximization Concerns o Sequence of Operation Optimization

• Staging Criteria

• Setpoints and Setbacks

o Up-to-date vs. Deferred Maintenance

o Auto vs. Manual Mode

o Accuracy of Graphics

Building Automation Systems can increase efficiency IF designed and commissioned appropriately.


16

Example #2: Variable Speed Drives


Installing or optimizing Variable Speed Drives can increase efficiency IF installed and commissioned correctly.

Benefits o Demand Based Control

Efficiency Maximization Concerns o Sequence of Operation Optimization

• Process Variable

• Minimum Speeds

o Auto vs. Manual Mode

o Base loading of equipment

HOTEL ENERGY EFFICIENCY Action

17

What ECMs are implemented?


Actions are determined through balancing your budget with your goals

Fixed Budget

Budget is the driver

Capital Cost is no issue

Payback is the driver

Goal of 20% GHG Reduction by 2020

Goal is the driver

HOTEL ENERGY EFFICIENCY Action

Sustainability Report and manage energy consumption

Energy Economics Budget through precise allocation

Reliability Improve reliability through understanding

Energy Efficiency Implement & track conservation measures

Utility Invoice Data

Benchmarking Comparison and analysis

EMS


Continuous commissioning and verification An energy management system (EMS) is not an ECM, but can be a valuable energy management tool
