ENERGY METRICS BREAKDOWN

The electrical usage1 for each building in this survey was analyzed to find the energy use intensity (EUI). Buildings

with the greatest energy usage per square foot are considered high priority buildings for energy conservation

measures. It is important to note that no weight is given to the building usage type. Calculation is based solely on

measured energy consumption per square foot of conditioned space.

LIGHTING UPGRADES

The Lighting Upgrades ECM entails upgrading the existing fixtures in each building to comparable LED fixtures, where

applicable. Depending on the fixture type, lamp type, and burn hours, retrofit or fixture replacement may be

proposed. In a retrofit application, the existing fixture is used to house the new LED lamp. Retrofit allows for many

of the same benefits as fixture replacement (e.g. energy savings, reduced operations and maintenance cost, longer

lamp life) while reducing first cost. LED replacement can reduce over fixture energy usage between 50-70% and

have a 4 to 5 times longer useful life.

APPLICABLE BUILDINGS

The Lighting Upgrades ECM is applicable to the following building(s) based on information provided by campus

personnel and information gathered during the preliminary walkthrough.

VARIABLE REFRIGERANT FLOW SYSTEM (VRF)

A VRF system uses variable speed compressors, refrigerant flow controllers, and variable speed blowers to optimize

the system energy performance across an entire building. Typically, a system has multiple outdoor units with branch

refrigerant circuits run to AHUs, FCUs, or wall or ceiling-mounted cassettes. Depending on the system type, outdoor

air requirements can be met through individual indoor units or through a dedicated system. VRF systems are ideal

for dormitory-style residence halls.


The Variable Refrigerant Flow System ECM is applicable to the following building(s) based on information provided

by campus personnel and information gathered during the preliminary walkthrough.

FACILITY GSF


DETAIL

The Appleby Complex includes two dormitory-style residence halls. A single, 130-ton air-cooled chiller and three (3)

HHW boilers provide heating and cooling to both buildings. Individual dorms are heated and cooled via 4-pipe fan

coil units (FCUs) with manual thermostats. The existing chiller is nearing the end of its useful life, and, according to

facility personnel, the FCU actuators are beginning to fail. A VRF system would provide the following benefit:

- A connected system would allow heat recovery across each building throughout the day.

- Compressors are only present in the outdoor units.

- Individual indoor units can be controlled or setpoint limited wirelessly.

- Individual indoor units can be combined with occupancy-based controls to setback when no occupants are

present.

- VRF systems have high part-load efficiency.

- VRF systems typically consume between 20-40% less energy than an air-cooled chilled water system.



8-17-19 Page 6 of 14

WATER-SOURCE HEAT PUMP SYSTEM (WSHP)

A Water-Source Heat Pump system uses condenser water as a heat rejection or injection medium for zone-level heat

pump systems. Condenser water is most typically passed through a cooling tower for waste-heat rejection.

Individual zone air handlers have refrigerant-based heat pumps. Depending on the climate of the installation site, a

HHW boiler could be used for heating backup when the outdoor air temperature is too low for the heat pumps to

properly function.


The Water-Source Heat Pump System ECM is applicable to the following building(s) based on information provided


FACILITY GSF



DETAIL

The following section provides detail on the existing and proposed systems applicable to this ECM.

APPLEBY COMPLEX




facility personnel, the FCU actuators are beginning to fail.

Due to the need for individually-controllable, zone-level heating and cooling, a WSHP system would reduce the

overall energy consumption of the building by allowing for a reduced compressor load during times of partial

occupancy as compared to the current constant-speed, air-cooled chiller.

FINE ARTS ANNEX

The Fine Arts Annex is a converted elementary school building located across from the main campus. The building

is currently heated and cooled by a combination of split systems, rooftop package units, wall-hung BARD units, and

window units. All units are individually controlled via manual thermostats.

Due to the need for zone-level heating and cooling, a WSHP system would reduce the overall energy consumption

of the building by switching from a majority air-cooled, less efficient system to a more efficient water-cooled system.

Also, zone units could be installed with BAS-style control to allow for occupancy scheduling and setpoint limiting

control.

RECREATION CENTER

The Recreation Center is a relatively new building. The facility is cooled by two (2), air-cooled chillers serving three

(3) CHW/Elec AHUs with 555 kW of heat. Some individual spaces are served by PIUs with electric heat. PIUs have

individual DDC thermostats.



8-17-19 Page 7 of 14

GROUND-SOURCE HEAT PUMP SYSTEM (GSHP)

A Ground-Source Heat Pump system uses condenser water as a heat rejection or injection medium for zone-level

heat pump systems. Condenser water is most through a deep ground wells for waste-heat rejection. Individual zone

air handlers have refrigerant-based heat pumps.


The Ground-Source Heat Pump System ECM is applicable to the following building(s) based on information provided


FACILITY GSF


DETAIL

The Fine Arts Annex is a converted elementary school building located across from the main campus. The building

is currently heated and cooled by a combination of split systems, rooftop package units, wall-hung BARD units, and

window units. All units are individually controlled via manual thermostats.

Due to the need for zone-level heating and cooling, a GSHP system would reduce the overall energy consumption of

the building by switching from a majority air-cooled, less efficient system to a more efficient water-cooled system.

Also, zone units could be installed with BAS-style control to allow for occupancy scheduling and setpoint limiting

control. Ground wells could be dug under the recreational field near the campus. A GSHP system would provide

the following benefit:

- A connected system would allow occupancy-based setbacks and setpoint limitation.

- Compressors are smaller and are sized to the space served.

- Individual indoor units can be controlled or setpoint limited wirelessly.

- Water-cooled systems have high efficiency as compared to air-cooled systems.

CHILLER UPGRADES

Chiller Upgrades are typically recommended for buildings with existing chilled water systems that are nearing or at

the end of their useful life. Upgrades can encompass strategies such as one-to-one replacement, efficiency

upgrades, or even variable-speed chillers. When a chiller is upgraded, it is most beneficial to implement a control

system for the building along with the upgrade if it is not already in place to allow for maximum energy savings and

lifetime out of the new chiller.


The Chiller Upgrades ECM is applicable to the following building(s) based on information provided by campus


FACILITY GSF


DETAIL




facility personnel, the FCU actuators are beginning to fail. Chiller Upgrades would provide the following benefit:

- Efficiency of the existing chiller has likely diminished due to age. A variable-speed, air-cooled chiller would

allow for a significant increase in performance efficiency under full and part-load conditions.

- The upgraded chiller should be connected to a BAS to allow for monitoring and control to optimize run-time

efficiency.

OCCUPANCY-BASED THERMOSTATS

Occupancy-Based Thermostats are typically recommended for buildings with individually-zoned systems that serve

areas with unscheduled occupancy. In this case, residence halls are an ideal application for these thermostats due

to the unpredictable nature of occupancy in each dorm room. Occupancy-based thermostats typically use

microphonic and infrared technology to detect occupancy. In an occupied room, the HVAC unit will function per

setpoint; however, when the room is left unoccupied for a pre-determined amount of time, the unit is set back to

preprogrammed setpoints. This can lead to significant energy and maintenance savings, especially when each room

unit has a fan and compressor.


The Occupancy-Based Thermostats ECM is applicable to the following building(s) based on information provided by

campus personnel and information gathered during the preliminary walkthrough.

ROLLINS

The Rollins residence hall is a dormitory-style residence hall. It is served by a water-source heat pump system with

backup HHW boilers. Individual dorms are heated and cooled via WSHP units with manual thermostats. The existing

system is towards the end of its useful life, and, according to facility personnel, has had several unit compressors fail

over the years.

HILLGROVE

The Hillgrove residence hall is a dormitory-style residence hall. It is served by a water-source heat pump system

with backup HHW boilers. Individual dorms are heated and cooled via WSHP units with manual thermostats. The

existing system is towards the end of its useful life.



8-17-19 Page 10 of 14

THERMOSTAT SETPOINT CONTROLS

Thermostat Setpoint Controls are typically recommended in facilities with HVAC systems that have a high degree of

occupancy influence over temperature setpoints. In residence halls, user setpoint controls can be especially energy

intensive if unrestricted. Smart thermostats can be installed which can, among other advanced features, limit the

degree of user control over the temperature setpoint to prevent excessive heating or cooling in a dorm room. Many

smart thermostats also have wireless communication technology to allow for mass temperature resets,

unoccupied/occupied modes, etc.

PROGRAMMABLE THERMOSTATS

Programmable Thermostats are typically installed on HVAC units with single-zones of predictable occupancy.

Depending on the initial investment, programmable thermostats can range from stand-alone thermostats which

have to be individually updated to wireless thermostats which are connected to a central online hub for observation

and control.


The Programmable Thermostats ECM is applicable to the following building(s) based on information provided by


FACILITY GSF

Library 31,451

Dining Hall 18,492

Clegg 32,661

Goolsby 41,354




DETAIL

The thermostats observed in each building listed above typically fell into one of two categories:

- Manual, stand-alone thermostat

- Programmable, stand-alone thermostat

In instances where a programmable thermostat was present, the large majority were not programmable to an

effective schedule for heating and cooling the building based on current occupancy patterns. By installing or

implementing programmable thermostats to setback or shutdown HVAC equipment during unoccupied periods,

energy costs in each building can be significantly reduced with a relatively small initial investment cost.

HVAC UPGRADES

The HVAC Upgrades ECM is a general measure to encompass necessary upgrades of equipment as they reach the

end of their useful life, either through age or maintenance issues. Upgraded equipment implementation can range

from a 1:1 replacement method to full design of replacement equipment based on the altered state of the facility

from its original design intent. HVAC Upgrades can also encompass energy efficiency upgrades.

DETAIL

Specific detail as to the HVAC configuration of each building can be found in the Building Summaries workbook in

the Appendix. The list below contains a selection of observed equipment with brief upgrade suggestions. Further

engineering analysis should be performed to determine the viability of each upgrade.

- Duckworth (Library): Upgrade existing split systems with high SEER split systems

- Dining Hall: Upgrade existing split systems with high SEER split systems

- Maxwell: Upgrade existing CT

- Clegg: Replace or remove existing window units

- Goolsby: Upgrade existing RTUs serving classrooms with high SEER RTUs

- Hillgrove: Upgrade non-functioning Hall Way units

- Pruitt-Barrett: Upgrade existing CT

- Fine Arts Annex: Upgrade all existing HVAC equipment nearing end of life to high SEER equipment.

BOILER UPGRADES

Boiler Upgrades typically refer to the replacement of existing boilers with new high efficiency boilers. This ECM can

also refer to the replacement of a facilities existing heating system with a modular boiler system if the facility has

varied occupancy throughout each day in the heating season.


The Boiler Upgrades ECM is applicable to the following building(s) based on information provided by campus


FACILITY GSF

Goolsby 41,354


DETAIL

GOOLSBY CENTER

The Goolsby Center is an academic building with classroom and lecture hall space. The facility also contains the two-

story “Black Box Theater”. A variety of units provides heating and cooling as detailed below.

- Three (3) DX/HHW AHUs (Black Box Theater)

- RTUs serving classrooms and lecture hall

- PIU(HHW-R) in each classroom with manual tstats

- Propane HHW boiler

The Goolsby Center boiler is nearing the end of its useful life and should be upgraded to ensure facility operation.

The boiler should be replaced with a new, higher efficiency propane boiler.

RECREATION CENTER

The Recreation Center is a relatively new building. The facility is cooled by two (2), air-cooled chillers serving three

(3) CHW/Elec AHUs with 555 kW of heat. Some individual spaces are served by PIUs with electric heat. PIUs have

individual DDC thermostats.

Due to the electric rate for the complex, a HHW system may reduce energy costs. Further engineering analysis is

required to verify this ECM. If a HHW system is installed, a modular boiler system is recommended based on the

varying occupancy of the facility as well as the range of activities that take place on a given day.



8-17-19 Page 14 of 14

COOLING TOWER UPGRADES

The Cooling Tower Upgrades ECM is recommended for buildings that require a cooling tower as part of their existing

HVAC system. A cooling tower that is past its useful life can have a negative effect on the energy consumption of a

water-source heat pump system.


The Cooling Tower Upgrades ECM is applicable to the following building(s) based on information provided by campus


FACILITY GSF


DETAIL

The Pruitt-Barrett building is heated and cooled by a water-source heat pump system with a HHW boiler backup.

The system is original to the building, and the cooling tower is nearing the end of life. The cooling tower fill is in

need of replacement, and the tower itself is leaking and has to be filled with makeup water regularly.

By upgrading the cooling tower, the efficiency of heat transfer, and therefore energy usage, of the entire system can

be improved.
