Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 14,570.70 MMBtu | 29,339 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) | 43,912 MMBtu | 59,465 MMBtu |
| Total | 58,482.70 MMBtu | 88,804 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | Jan. 1, 2015 | Dec. 31, 2015 |
| Baseline Year | Jan. 1, 2005 | Dec. 31, 2005 |
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):
The Climae Actuion Plan uses 2005 as the baseline for all energy and emissions metrics.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 1,747,298 Gross square feet | 1,652,587 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 | 0.03 MMBtu per square foot | 0.05 MMBtu per square foot |
| Source energy | 0.05 MMBtu per square foot | 0.09 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 | 6,135 Degree-Days (°F) |
| Cooling degree days | 637 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 36,855 Square feet |
| Healthcare space | 10,660 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):
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Clark University policy is to set temperatures at 78 degrees for cooling, 68 degrees for heating and 130 degrees for domestic hot water. During the heating season, the temperature in residence halls and houses will be set at 68 degrees during the day and 65 degrees at night. Academic and office buildings will be set at 68 degrees during the day and 62 degrees at night. Unoccupied buildings, which are buildings not in use, will have a temperature of 55-60 degrees at times such as semester breaks and any holidays numbering three days or more. The daytime temperature setting refers to 6:00 a.m. to 5:00 p.m. on weekdays for academic and office buildings and 6:00 a.m. to 10:00 p.m. for residence halls and houses throughout the week. During weekends and holidays of two days or less, temperature for office and academic buildings will be set at 60 degrees. An advanced Schneider Energy Management System, with sensors on all floors in all buildings, is monitored 24/7.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Dorm room desk lights and library study carrell lighting is LED strip lighting where possible. Laboratory equipment, appliances, etc. LED equipped where supplied. Exterior lighting is all LED's. Where possible, fixtures have been adapted to LED andall newly installed fixtures are LED. Theater and visual arts are now all LED, too.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
Ground-breaking in its time, Clark's old cogeneration engine cranked faithfully away underneath Jonas Clark Hall from1982-2012, producing electricity for central campus and capturing the waste heat from electrical generation in a complex water loop that provides thermal energy — heat — to many campus buildings. In 2010, the cogen switched from oil to natural gas, greatly reducing greenhouse gas emissions and improving the engine's efficiency a little, but still not to modern standards. A recent incentive program allowed Clark to upgrade the old cogen to a larger and much more efficient 2.0 MW engine, in full operation January 2013. The new cogen is already making a difference, operating with efficiencies 50% greater than previous, reducing particulate matter, and expected to reduce GHG emissions from co-gen operations due to its more efficient use of fuel.
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):
We are 3/4 of the way through a full set of investment-grade building audit recommendations, which included retrocommissioning all large academic and residential buildings.
