Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 723,551 MMBtu | 720,443 MMBtu |
| Electricity from on-site renewables | 14.80 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 783,044 MMBtu | 828,013 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 98,078 MMBtu | 104,555 MMBtu |
| Total | 1,604,687.80 MMBtu | 1,653,011 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2016 | June 30, 2017 |
| Baseline Year | July 1, 2010 | June 30, 2011 |
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):
2011 was the year of the University's 2nd Greenhouse Gas inventory, and was selected as a baseline as we believe the data set was more accurate than that used for the previous inventory.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 10,232,691 Gross square feet | 9,447,142 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 | 0.16 MMBtu per square foot | 0.17 MMBtu per square foot |
| Source energy | 0.32 MMBtu per square foot | 0.36 MMBtu per square foot |
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):
| Degree days (see help icon above) | |
| Heating degree days | 4,650 Degree-Days (°F) |
| Cooling degree days | 1,037 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 2,536,066 Square feet |
| Healthcare space | 0 Square feet |
| Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
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):
Sustainability Plan with the full-throated endorsement of the Chancellor released on December 8, 2017 which has goals to reduce energy use by 50% by 2030.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The University's standard indoor air temperature setpoints are as follows:
a. Winter Indoor Air Dry Bulb Temperature
i. All occupied spaces: 70º F ± 2º F with nighttime and weekend setbacks to 60º F
ii. Labs housing and caring for animals: As required by the current edition of “Guide for Care and Use of Laboratory Animals.”
iii. Unoccupied spaces (such as storage rooms, vestibules, etc.): 55ºF ± 5º F
iv. Unoccupied spaces (such as mechanical equipment rooms, electrical equipment rooms, etc.): 55ºF minimum.
v. Unoccupied spaces (such as toilet rooms): 68º F ± 2º F.
vi. Elevator equipment rooms: 40°F minimum and 90º F maximum.
b. Summer Indoor Air Dry Bulb and Wet Bulb Temperatures:
i. All occupied spaces: 74º F ± 2º F with maximum 57º F WB with nighttime and weekend setbacks to 80º F
ii. Labs housing and caring for animals: As required by the current edition of “Guide for Care and Use of Laboratory Animals.”
iii. Unoccupied spaces (such as storage rooms, vestibules, etc.): 80ºF ± 5º F with maximum 62º F WB.
iv. Unoccupied spaces (such as mechanical equipment rooms, electrical equipment rooms, etc.): 90ºF maximum, non-condensing conditions at all times.
v. Unoccupied spaces (such as toilet rooms): 78º F ± 2º F with maximum 57º F WB.
vi. Elevator equipment rooms: 40°F minimum and 90º F maximum, non-condensing conditions at all times.
University standards require vacancy sensor to be used to control lighting in all spaces where occupants may want lights off when occupied (e.g., offices, classrooms, and labs); occupancy sensors are required in all spaces where lights must be on when occupied (e.g., restrooms and corridors); photocells or timeclocks are required to control all outdoor lighting; even emergency lighting is required to be automatically shut off when spaces are unoccupied (generator transfer devices are used to automatically turn emergency lights on when normal power is lost).
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
LED lighting has recently been installed in several significant locations within the University, and is planned for several large renovations in the near future. For example, the University's two largest lecture halls were retrofitted with LED lighting in FY15. The University carefully considers and tests new technologies prior to large-scale implementations to ensure suitability and performance. As LED technology has improved, the number of installations is increasing. LED lighting is now deemed acceptable for most new installations and retrofits.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A small solar array is installed and active at the Swanson School of Engineering and is used primarily for educational and research purposes.
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 University has recently expanded its retro-commissioning group who is charged with periodic retro-commissioning in existing facilities in order to ensure that buildings are operating optimally and to identify areas for energy and operational improvements. In addition, building commissioning (often enhanced commissioning) is performed by independent third parties for major construction and renovation projects. Major recommissioning efforts have been recently completed for the University's two main chilled water generation facilities, and a utility meter retro-commissioning project was completed in FY16. Significant savings have been recognized in several recent retro-commissioning projects.
An Energy Master Plan and Energy Conservation Plan were completed in September 2017. Implementation of identified Energy Conservation Measures (ECMs) began shortly thereafter and will continue until all viable ECMs are completed.
In December 2017 the University issued a Sustainability Plan with a goal to reduce energy use by 50% by 2030 from a 2003 national average baseline.
