Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 1,181,055 MMBtu 1,093,808 MMBtu
Electricity from on-site renewables 252 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) 1,644,402 MMBtu 1,561,655 MMBtu
Total 2,825,709 MMBtu 2,655,463 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2017 June 30, 2018
Baseline Year July 1, 2009 June 30, 2010

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):

Our baseline matches our Emissions Reduction Plan Baseline of FY2010.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 20,600,321 Gross Square Feet 17,134,498 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.14 MMBtu / GSF 0.15 MMBtu / GSF
Source energy 0.26 MMBtu / GSF 0.29 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:

Degree days, performance year (base 65 °F / 18 °C):

Heating degree days 4,491 Degree-Days (°F)
Cooling degree days 1,373 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 1,273,873 Square Feet
Healthcare space 3,358,102 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
29,968,375 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
16.08 Btu / GSF / Degree-Day (°F)

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):

In 2016 the University Facilities Management Division contracted with Cenergistic, Inc. to optimize the building operations. Cenergistic Energy Specialists work on-site with Facilities Management employees to monitor energy usage in campus facilities, find conservation opportunities and implement energy savings strategies.

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

The University operates a 24/7 Building Automation center known as the Delta Room. Space temperatures are controlled between 74 and 68 degrees year round, with occupants generally having control within that range. After hours and on weekends or holidays, temperatures ranges are widened to 60 and 80 degrees for energy conservation. A similar system is used for the Medical Center Physical Plant, but temperature ranges are dependent upon healthcare and research requirements. The energy policy is published on the Utilities and Energy Management website. Occupancy sensing is also being added during lighting retrofits and new construction.

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

All new construction is using LED technologies, and standards have been written that prohibit using anything other than LED if a suitable LED solution exists. We have also started retrofitting LED fixtures with integrated occupancy sensors in common spaces to maximize the savings opportunities.

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

One passive solar-thermal array is situated on the roof of the Poundstone Regulatory Services Facility. This 8-panel system provides heating for the building domestic hot water supply and has a peak output of approximately 256,000 BTU/day. Two small solar PV arrays also exist on campus, of approximately 26kW and 56kW peak production each.

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

Cogeneration is not currently in use on the campus, but is listed as an option for exploration in Phase 2 of the Greenhouse Gas Emissions Reduction Plan (FY21-FY25).

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 University is aggressively renovating multiple existing buildings, including Commonwealth Stadium, Gatton School of Business, and The Student Center. Renovation and new construction usually include a third-party retro-commissioning agent to ensure the highest quality construction per design. Additionally, multiple renovations are performed by the Campus Physical Plant to increase energy efficiency and save money, such as lighting retrofits. The energy program has also installed various smart thermostats and plug load controls for stand-alone HVAC systems (i.e. window air conditioners, campus owned houses) that allow for remote scheduling without extensive capital investment.
