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

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 64,811.32 MMBtu 69,513.22 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) 65,427.44 MMBtu 85,030.19 MMBtu
Total 130,238.76 MMBtu 154,543.41 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2015 June 30, 2016
Baseline Year July 1, 2008 June 30, 2009

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 baseline year of FY2009 was decided up on as this was the year that the Climate Action Plan and Sustainability Plan were being developed.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 932,912 Gross Square Feet 932,912 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 0.17 MMBtu / GSF
Source energy 0.29 MMBtu / GSF 0.33 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):
Degree days (see help icon above)
Heating degree days 6,051 Degree-Days (°F)
Cooling degree days 571 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 32,490 Square Feet
Healthcare space 0 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
1,083,296 Gross Square Feet

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

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):

CLC sends out biweekly Sust'y eBlast emails in which faculty and staff share their own personal stories about what they are doing or contributing to make the college more sustainable. Messages often include initiatives to remind people to turn their computers and printers off at night, and especially during breaks.

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

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

CLC has been replacing metal hallide and flourescent lighting with LED fixtures. This is an incremental process, beginning with our oldest buildings being renovated and in the new construction areas. Currently we received a grant to help fund conversion of lighting in parking lots and internal roadways to LED.

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

CLC is currently rolling out its master plan construction. In the fall 2016, our gothermal heat exchange system came on line, with 80 wells drilled 500 ft deep. In the fall 2017, we expect 47 new wells to come on line to heat and cool the new Science Building, when it opens.

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):

CLC has been working with SEDAC for retro-commissioning reports on our HVAC systems. These reports help facilities staff to decide when and where to install upgrades to make our systems more efficient.
