Esby Gymnasium and Recreation Center HVAC Study MARCH 7, 2014

1.0 EXECUTIVE SUMMARY

Rowan University engaged Burns Engineering to perform a study to evaluate existing temperature and

humidity control issues in the Esby and Recreation Center Gymnasiums as well as in the aerobics and

free weight rooms on the second floor of the Recreation Center.

The Aerobics Area/Free Weights Room HVAC system was determined to be undersized and has

inadequate ventilation air as does the Esby Gymnasium HVAC System. While the total capacity of the

three AHUs serving the Rec Center gymnasium are adequate, neither the Rec Center units (Unitary

Water Source Heat Pumps (WSHPs)) nor the constant volume, 2-pipe Air Handling Units (AHUs) provide

the humidity control necessary for the high latent and variable occupant loads common for health club

and gymnasium type spaces. Additional concerns regarding the existing two pipe changeover systems

were noted as a 100 gpm booster pump that was originally furnished with an incorrectly sized Heat

Exchanger is installed in series with the larger 200gpm dual temperature pumps and is currently not

energized.

To address both ventilation and humidity control problems prevalent in all three spaces we recommend

the following:

• Rec Center (Aerobics Room/Free Weights): Replace existing WSHPs with new packaged rooftop,

water cooled heat pump. Unit should include Variable Air Volume (VAV) fan control, modulating

compressors and modulating hot gas reheat as well as energy recovery. CO2 sensors should also

be included to control ventilation air amounts. Order of Magnitude Cost: $265,000

• Rec Center Gymansium: Replace (3) modular AHUs with new units of similar size. New units

should include VAV system to allow for passive dehumidification during part load conditions.

Order of Magnitude Cost: $190,000

• Esby Gymansium: Replace (2) constant volume AHUs with (1) new rooftop AHU with 2 pipe

changeover coil. New unit should include VAV to allow for passive dehumidification during part

load conditions and an energy recovery wheel. Add CO2 sensors to control ventilation air

amounts. Order of Magnitude Cost: $330,000

Refer to Appendix C for breakdown of costs. Evaluation of the roof structure, electrical capacity required

and any modifications required to the hydronic systems to accommodate the increase in load were not

evaluated as part of this study and should be investigated further.

If the two pipe changeover pumps, piping or heat exchangers are required to be replaced to

accommodate the increase in load, the University should investigate converting the system over to a

four pipe system as the current two pipe system does not allow for easy changeover from heating to

cooling during the shoulder months. A four pipe system would also allow for reheat in the Rec Center

and Gymnasium AHUs to provide active humidity control though this would require steam in the

summer months. Other methods of active dehumidification such as series dessicant wheels or recovery

of condenser water heat from the water source heat pumps for reheat could also be considered.

2.0 INTRODUCTION

Rowan University engaged Burns Engineering to perform a study to evaluate existing temperature and

humidity control issues in the Esby and Recreation Center Gymnasiums as well in the aerobics and free

weight rooms on the second floor of the Recreation Center.

Both the Rec Center Gymnasium (1994) and Esby Gymnasium (1961) suffer from high humidity and

warmer than expected temperatures. HVAC units for both spaces are served by a two pipe, heating and

cooling changeover system. Chilled water supply serving both buildings is from a plate and frame heat

exchanger and constant speed pump located in the Rec Center basement with the cold side of the heat

exchanger supplied from the campus chilled water loop. The workout areas on the second floor are

served by Water Source Heat Pumps (WSHPs). Condenser water for the WSHPs is also supplied through

a plate and frame heat exchanger located in the basement of the Rec Center Gym with the heat rejected

to the campus chilled water loop. The cold side of the two (2) plate and frame heat exchangers are

arranged in series with incoming campus chilled water supply flowing through the first heat exchanger

serving the 2 pipe system (43EWT-48LWT) and then through the second heat exchanger to remove the

heat rejected from the WSHPs (48EWT).

The Rec Center and Esby Gymnasiums also contain Natatoriums, racquetball courts, locker rooms and

administrative spaces that are not included in the scope of this study. The findings and observations

discussed in the following sections are based on Burns visual inspection of the HVAC systems during our

site visits on 1/29/14.

3.0 RECREATION CENTER - WORKOUT AREAS

3.1 EXISTING CONDITIONS

The aerobics and free weight rooms (9,500sf) in the Rec Center contain treadmills, resistance

training machines, free weights and other equipment typical to a health club type occupancy.

Cooling is provided by seven (7) WSHPs varying from 3 to 3.5 tons of total capacity. The condenser

water loop rejects its heat to the campus chilled water system as described above. A 100% Outside

Air, Heating and Ventilating (H&V) Unit provides ventilation air to these spaces as well as the

adjacent racquetball courts. While the ventilation air is directly connected to the return ductwork of

the WSHPs serving the racquetball courts, the ventilation supply to the units serving the workout

areas is discharged into the ceiling return plenum and is not directly coupled with the units.

It is our understanding that these areas have experienced both high temperature and humidity

issues. In attempts to remedy the situation, the University has added solar reducing tint to the

windows and skylights and has recently replaced the WSHPs in kind with little result.

3.2 SYSTEM SIZING AND EVALUATION

Burns reviewed the original building architectural and engineering drawings by Daniel F. Tulley

Associates (1991). The exterior walls were brick exterior with an air gap, 6 inches of batt insulation

and gypsum board finish on the interior. Windows appeared to be double pane insulated glass and

had since been furnished with solar reducing tint. Roof construction consists of metal deck and 3

inches of rigid insulation. Occupant Density was modeled based on data logged by the University for

maximum occupancy in the workout areas at 200 people. Based on these parameters and design

internal summer conditions of 75F/60%max RH, we calculated the following performance

requirements using Carrier’s Hourly Analysis Software (HAP) and compared the results to the

existing equipment capacities (See Appendix B for Load Calc Summary Pages):

• Aerobics/Weight Room: 13,500 cfm @ 60 Tons Total Coil Load (0.59 SHR)

o Ventilation Air Required: 4,570cfm based on 200 people (2009 IMC)

• Existing Units Total: 9,750cfm @ 23 Tons Total Coil Load

o Ventilation Air: 1,500cfm

It was determined that the existing units are undersized based on a peak occupancy during a design

cooling day. Even if sized properly, however, this type of unitary equipment is not adequate for the

variable occupancies or high latent loads of a health club environment. This is because with constant

volume units and single stage compressors, the cooling cycle is either on or off. Since HVAC

equipment predominantly operates at part load conditions most of the year, the compressors cycle

on and off and as they cycle off, they lose their ability to dehumidify the air. On a mild day with

limited sensible load from the outside but maximum occupants working out inside sweating, the

compressors would cycle on and off to maintain space temperature only, though humidity control

would still be required. Exacerbating the problem is that cooling coils are most inefficient at

dehumidification when they startup because the dewpoint temperature of the coil hasn’t dropped

low enough to effectively dehumidify the air. Frequent cycling doesn’t allow time for the cooling

coils to operate in the lower temperature range necessary for humidity control. Also, as the supply

fan continues to run, any condensation that does form on the coil is reabsorbed by the

unconditioned air and the condensed water effectively returned back to the space to be

dehumidified twice.

The ventilation air quantity is also inadequate based on the anticipated space occupancy and in

compliance with current codes (2009 International Mechanical Code (IMC)). The ventilation

effectiveness of the existing air quantity is also questionable since it is not directly coupled with the

units.

3.3 RECOMMENDATIONS

Burns determined that replacing the existing system “in kind” with larger capacity unitary heat

pumps was not appropriate for this type of occupancy for the reasons describe above. It is also our



4

understanding that the existing units are already difficult to maintain above the ceiling with mimial

maintenance access to the components due to clearances with the structural steel.

Therefore we recommend a packaged rooftop heat pump to serve the workout areas of both

spaces. We recommend that the unit be Variable Air Volume(VAV), with a modulating compressor

and modulating hot gas reheat coil for humidity control. CO2 sensors and demand controlled

ventilation (DCV) is required by ASHRAE 90.1-2007 for spaces with an occupant density above 40

people/1000sf such as a health club environment.

The VAV system will help to provide passive dehumidification to the space by reducing the supply

airflow volume during part load conditions. Since the cooling coil is still active, dehumidification is

still being performed as opposed to a constant volume system with On-Off control of the

compressor. The modulating compressor keeps the compressor running at part load conditions to

avoid compressor cycling as described above. Though this approach alone would only provide

“passive” dehumidification since the unit will be running to maintain space temperature setpoint

only, a modulating hot gas reheat coil recycles waste heat from the compressor and would allow for

active humidity control by using hot refrigerant gas from the compressor to reheat the air for both

precise temperature and humidity control. Reheat is allowed by ASHRAE 90.1-2007 where system

airflows can be reduced by 50%(or to the minimum ventilation rate whichever is greater) or is

provided by site recovered energy as with the hot gas reheat approach. Due to the high latent load

of the space, a low leaving wetbulb temperature is also required (51F, refer to Appendix B load

calcs) to increase the latent capacity of the supply air. While it is not part of the scope of this report,

the condenser water heat exchanger, pumps and piping system will need to be evaluated to verify

they can accommodate the increased heat rejection load (appx. 50 gpm increase at equivalent delta

T). An energy recovery wheel was included in the preliminary equipment selections to limit the

increase to the condenser water loop.

Evaluation of the roof structure, the increased electrical capacity required for the new unit and the

adequacy of the condenser water loop was not evaluated as part of this study and should be

investigated further during preliminary design.

4.0 RECREATION CENTER - GYMNASIUM


The Rec Center Gymnasium (24,000sf) is a 30 foot tall structure and contains multiple basketball

courts on the first floor and has a running track and concourse area for access to the racquetball

courts and adjacent spaces on the second floor. Cooling is provided by three (3) modular air

handling units hung in the ceiling of the gym with 2 pipe changeover coil for heating/cooling. Return

air for the center unit is in the ceiling of the second floor concourse area while return air for the two

end units are at the court level which is typical for air distribution with a high bay ceiling. The units

are 6,000 cfm each (1,500cfm OA) and are arranged for economizer control (free cooling). Three (3)



5

6,000cfm exhaust fans in the gym roof provide exhaust during economizer control, with (1) fan

running during normal operation. The 2 pipe changeover loop is supplied by a plate and frame heat

exchanger in the summer as described above with heat supplied from a separate heat exchanger

supplied by the campus steam loop.

Heat from the Electrical Equipment Room 136 and Storage Room 134 is exhausted into the

gymnasium at 3,000cfm.


issues in the summer.


Burns reviewed the original building architectural and engineering drawings by Daniel F. Tulley

Associates (1991). The exterior walls for the gymnasium are a face brick exterior with 2 inches of

rigid insulation and CMU on the interior. Windows and skylights appeared to be double pane

insulated glass with solar reducing tint. Roof construction consists of metal deck and 3 inches of rigid

insulation. Occupant Density was assumed to be approximately 50 people on the basketball courts

and 20 people on the track level above at a high activity level. Based on these parameters, including

the 3,000cfm of exhaust from adjacent equipment spaces and design internal summer conditions of

75F/60%max RH, we calculated the following performance requirements using Carrier’s Hourly

Analysis Software (HAP) and compared the results to the existing equipment capacities (See

Appendix B for Load Calc Summary Pages):

• Rec Center Gym: 18,250 cfm @ 60 Tons Total Coil Load (0.65 SHR)

o Ventilation Air Required: 7,200cfm based on 0.30cfm/sf for gym areas (2009 IMC)

• Existing Units Total: 18,000cfm @ 60 Tons Total Coil Load

o Ventilation Air: 4,500cfm

It was determined that the existing units appear to be sized adequately for the total coil load,

however, the constant volume two pipe changeover system does not provide adequate humidity

control of the space during part load conditions. As described above for the WSHPs, a constant

volume AHU with a chilled water coil will operate in much the same way during part load conditions.

The chilled water coil will begin to shutdown to match the space temperature setpoint regardless if

humidity control is still required. As chilled water flow to the coil is reduced because the space

temperature is satisfied, the leaving coil temperature increases. This increase in dewpoint of the coil

and wetbulb temperature of the supply air effects the dehumidification capacity of the system. A

two pipe changeover system can also make things difficult during the shoulder months because

once the system is turned over to heating, cooling may no longer be available but humidity control is

still required.

The ventilation air quantity would be inadequate based on current codes (2009 IMC), however, the

ventilation rates may have complied with code at the time of construction.

It is also our understanding that when the series plate and frame heat exchangers were first

installed that the heat exchanger for the 2 pipe changeover system was undersized and did not

account for the 2 pipe changeover coils added to the Esby Gymansium H&V units. This was

confirmed by our review of the Concord Engineering drawing M-201 (2006) which had the building

chilled water flow scheduled at 110gpm/11deg delta T (56EWT-45LWT) and the primary chilled

water supply at 240gpm/5deg delta T (42EWT-47LWT). A new plate and frame heat exchanger was

furnished and installed in late 2012/early 2013 with minimal effect. We reviewed the JJ White HX

submittal (dated 10-10-12) and verified that the new HX-1 had the building chilled water flow

scheduled at 185gpm/12deg delta T (56EWT-44LWT) and the primary chilled water supply at

240gpm/11deg delta T (43EWT-54LWT). Based on our review of the original Daniel F. Tulley

Drawings H-6 and H-8 (1991), the scheduled chilled water flow required to the Rec Center and Esby

Gym 2 pipe changeover system is actually 216gpm/12 deg delta T (44EWT-56LWT), a 16%

difference between the scheduled flows of the HX-1 and the building chilled water demands.

Additionally, Concord Engineering drawing M-201 notes an 110gpm circulation pump labeled P-1

that is not noted in the Scope of Work from JJ White to be dual temperature pumps P-3 and P-4

noted on the Tulley design drawings and rated at 200gpm. Series pumping usually involves two

pumps at similar flow rates to boost the total head of the system. If the original booster pump was

sized on an incorrect flowrate, it may be limiting the system flow due to its installation in series with

the larger building pumps.

4.3 RECOMMENDATIONS

Based on our evaluation described above it appears that the air handling equipment serving the

space is sized adequetley for the space loads of the Rec Center Gymnasium at peak conditions,

however, the constant volume system provides no means for humidity control at part load

conditions. Also, various descrepancies between original design chilled water temperatures and

flows raise questions regarding the current system operation and balancing.

We recommend the following: (1) Rowan verify the system balancing and analyze the two pipe

changeover system hydraulics to verify that the existing building pumps are adequately sized for the

scheduled flow and pressure drop and if the in-line circulation pump is required or should be

resized. (2) The three (3) modular AHUs serving the Rec Center gymansium be replaced with VAV,

two pipe units. By varying the airlow in relation to space temperature instead of the chilled water

flow, the system supply air temperature remains low or even lower during partload conditions

allowing for passive dehumidification. The existing AHUs serving the space are now approximately

20 years old and nearing the end of their useful life. If the heating/cooling system was converted to

a 4 pipe system, reheat could be added for active humidity control in the space. Lowering the

supply air temperature can further increase the latent capacity of the new units but should be

reviewed with the hydronic system modifications required.

Demand controlled ventilation is not required for this gym since there is no spectator seating and

therefore not a high occupant density.

5.0 ESBY GYMNASIUM


The Esby Gymnasium (25,500sf) is a 30 foot tall structure and contains multiple basketball courts

similar to the Rec Center Gymansium. The gym can be divided into two separate sections: Courts

1&2(17,600sf) and Courts 3&4 (7,920sf) by a fabric moveable partition. The larger courts 1&2 also

contain fixed bleacher seating for spectators during recreational activities such as NCAA Div. III

Basketball games. Cooling is provided by two (2) Air Handling Units (AHUs) in a penthouse

mechanical room adjacent to the courts. The units appear to have been replaced in kind in 1991

with the construction of the Rec Center while the return fans are original construction. The units are

essentially replacements of the original H&V units containing steam preheat coils with 2 pipe

changeover coils for heating/cooling added in the discharge ductwork of both units. AHU-1 serves

Esby Gym courts 3&4 and is 7,500cfm. AHU-4 serves Esby Gym courts 1&2 and is 13,000cfm.

Supply air is distributed at the roof level with low return grilles to limit stratification in the high bay

space. Return air is then distributed via direct buried transite piping below the gymnasium slab and

up through a shaft to the penthouse mechanical room. Existing ventilation rates were not scheduled

for the cooling coils but based on the cooling coil selection of 80F entering air temperature, a 30%

outside air amount can be assumed (91.5F design outdoor/75F indoor). The 2 pipe changeover loop

is supplied by a plate and frame heat exchanger as described in the Section 2.0 above.

Six (6) auxiliary rooftop exhaust fans are sized for 38,400cfm (6400cfm ea.) for Courts 1&2 and four

(4) fans at 22,400cfm (5600cfm ea.) for Courts 3&4. These appear to have been sized for appx

2.5cfm/sf or 12 air changes per hour (ACH) for summer ventilation with direct makeup coming from

the outside or adjacent spaces.


issues in the summer.


Burns reviewed the original building engineering drawings by Kelly and Gruzen (1961). The exterior

walls for the gymnasium are similar to the Rec Center with a face brick exterior and CMU on the

interior. No Windows or skylights are installed in this gym and the roof construction was assumed to

be consistent with the Rec Center. Occupant Density was based on the maximum number of

spectators/occupants that could occupy the fixed bleacher seating (1380people) at a seated activity

level. Ventilation requirements were calculated by dividing the court into two zones: (1) spectator

area and (2) play area for calculation of the outside air requirements in conformance with current

codes. Based on these parameters, and design internal summer conditions of 75F/60%max RH, we

calculated the following performance requirements using Carrier’s Hourly Analysis Software (HAP)

and compared the results to the existing equipment capacities (See Appendix B for Load Calcs):



8

• Esby Gym: 20,100 cfm @ 100 Tons Total Coil Load(0.60 SHR)

o Ventilation Air Required: 17,000cfm based on 0.30cfm/sf for gym area and 1380

people for the spectator area (2009 IMC)

• Existing Units Total: 20, 500cfm @ 58 Tons Total Coil Load

o Ventilation Air: 6,150cfm (based on 30%OA)

It was determined that the supply air volume from the Esby Gym units appears adequate for the

space sensible loads (the increase in total load for the new unit is related to the increased load from

the higher ventilation air quantity required) but the constant volume system with two pipe

changeover coils offer no means for humidity control at part load conditions as described in

previous sections. We also noted that since the cooling coils were retrofitted into the existing

discharge ductwork that abrupt transitions prior to and after the coil may also be reducing their

effectiveness along with the potential hydronic flow concerns noted in Section 4 above.

The ventilation rate is also inadequate. When the system was originally designed the auxiliary roof

exhaust fans would run to furnish additional ventilation air in the summer or the H&V unit would

operate at 100% outside air during the winter as the heating coils are adequately sized for this

arrangement. When mechanical cooling was added, however, the ventilation requirements for the

space during the summer were never addressed and the cooling coils sized for only 30%OA as noted

above. Running the exhaust fans during the summer to increase ventilation to the space would only

increase infiltration of unconditioned and humid air leading to condensation. The gymnsium should

be maintained at a slightly positive pressure to its surrounding environment to limit infiltration from

the outdoors as well as its proximity to the Natatorium which should be maintained negative to its

surrounding environment.

5.3 RECOMMENDATIONS

We recommend that a new VAV, two pipe rooftop unit AHU be installed to replace the two existing

20 year old constant volume units. The new VAV unit will allow for passive dehumidification during

part load conditions. Due to the occupant loading on the bleachers, the system requires almost 80%

Outside Air(OA). An energy recovery wheel is required by code due to the high ventilation air

volume as is Demand Controlled Ventilation. One unit was selected in lieu of two as was originally

designed for cost savings.

The existing rooftop exhaust fans should be removed as the new AHU would provide the full

ventilation requirements to the space. Due to the increase in load, the chilled water system flow will

be required to increase by appx. 40gpm to the Esby gym. The incoming chilled water piping and

Heat Exchangers should also be evaluated to verify they can accommodate the additional load

though conversion of the system to a 4 pipe system would allow for the addition of reheat and

therefore active humdity control in the space. Lowering the supply air temperature can further

increase the latent capacity of the new unit but should be reviewed with the hydronic system

modifications required.
