"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 154,093.60 MMBtu 100,010 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 100,245 MMBtu 86,748 MMBtu
Total 254,338.60 MMBtu 186,758 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Jan. 1, 2018 Dec. 31, 2018
Baseline Year Jan. 1, 2013 Dec. 31, 2013

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

In 2009 we began placing our electrical services lines underground. This moved the measuring meters for consumption from 16 buildings to one primary meter. To manage this energy and the resultant demand charges it became apparent that we needed to manage our HVAC and lighting systems more effectively. By putting our HVAC systems under control we have been able to not only manage our demand charges but, have been successful in reducing the energy required to climate control the affected buildings.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
---

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

We use time of day scheduling to operate some buildings with occupied/unoccupied temperature settings. Timers are software logic to manage equipment settings.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

LED Lighting has been incorporated into new construction standards and installed at Baskin, Dickens, Horrell Hall, and McAfee. New garages have LED lighting installed, and LED retrofits have been completed in both the North and CEC Garages. The primary sports arena was retrofitted for LED lighting. Exterior LED conversions are in progress. The Ayers Academic Center, Russell Hall (a residence hall) and the new Tall Hall (a residence hall) are LED. In August 2015, the new Johnson Center Building was opened with all LED lighting with centralized controls. The Jack Massey Center was renovated in 2015 and opened with new LED lighting and central controls as well. All centralized lighting controls are web-based.
During 2016 the Curb Center Garage and North Garage were both completely retro fitted to LED technology.
Comprehensive lighting controls have been incorporated into all spaces at the Ayers, Johnson, and Jack Massey Centers.
Dorms and other LED installs utilize stand-a-lone sensors to turn lights on/off automatically.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Classrooms and lobby spaces in the Ayers Academic Center are designed around the perimeter of the building in order to maximize passive solar lighting.
Our Baskin Law School Building and Johnson Academic Center are both designed with Geothermal heating and air-conditioning systems. These geothermal systems are operated to maximize heat retained in the building during winter months and reject heat to the ground during cooling seasons. This attention to where heat is rejected reduces the amount of heat rejected to the atmosphere along with reducing the amount of work (energy) required by individual equipment in the building.


A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):

The Hitch Science building has been retrofitted with energy efficient VRF air conditioning and heating along with LED lights and stand-alone lighting controls. The Massey Business Center was retrofitted with high efficiency boilers and LED lighting. The Maddox residence hall was retrofitted with a high efficiency chiller and a new high efficiency boiler system was installed in 2016. Our Bunch Library received a Chiller upgrade which improved operating efficiencies, reducing energy consumption while improving occupant comfort levels. Our Massey Performing Arts Center received a chiller replacement which also improved operating efficiencies, reduced energy consumption and improved occupant comfort levels. These equipment upgrades greatly improved reliability of optimal operating conditions.
We also replaced a 1960's diesel powered generator with a generator that utilizes natural gas as the fuel source. This initiative has reduced our scope 1 emissions at that source point.
