Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 35,296.36 MMBtu 32,561.57 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) 37,226.50 MMBtu 38,547.90 MMBtu
Total 72,522.86 MMBtu 71,109.47 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, 2016 June 30, 2017

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 Climate Leadership Network commitment began around 2007-2008 and serves as the baseline. The college is currently conducting a carbon emissions inventory, has an Energy Star purchasing policy, and is working with an energy service company to develop an energy conservation project. The college also participated in a Consortium-wide analysis of utilities consumption over the past 20 years.


Gross floor area of building space:

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):

Story House has developed thermostat “set‐point” protocols for the various buildings on campus, and thermostats can be adjusted only within the range provided. In addition, for building safety and energy conservation reasons, each building’s HVAC system should be the only method of heating or air conditioning the building. Occupancy sensors exist in most buildings.


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

CMC underwent a campus-wide lighting ballast conversion in 2011. Conversions to LED fixtures continue with 70 outdoor lighting poles converting from high-pressure sodium lamps to LEDs that use 76% less energy.


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

n/a


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

n/a


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):

In May 2007, the college adopted a policy requiring that all new construction achieve LEED Silver certification or higher. A campus housing energy efficiency retrofit program was implemented in fall 2007.
