Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 63,623.36 MMBtu | 66,126.70 MMBtu |
| Electricity from on-site renewables | 365.98 MMBtu | 451.89 MMBtu |
| District steam/hot water (sourced from offsite) | 132,287.55 MMBtu | 133,020.95 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 146,861.07 MMBtu | 150,568.07 MMBtu |
| Total | 343,137.96 MMBtu | 350,167.61 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, 2014 | June 30, 2015 |
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):
FY 2015 is the most complete and recent year KSC has submitted consistent energy data for the entire campus for our Greenhouse gas inventory.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 149,224.70 Gross square meters | 149,224.70 Gross square meters |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 2.30 MMBtu per square meter | 2.35 MMBtu per square meter |
| Source energy | 3.39 MMBtu per square meter | 3.47 MMBtu per square meter |
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 | 6,430 Degree-Days (°C) |
| Cooling degree days | 409 Degree-Days (°C) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 8,900.94 Square meters |
| Healthcare space | Square meters |
| 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):
We use our BAS systems to regulate temperatures based on occupancy hours in many of our buildings.
In some of our older buildings, we use timers for managing exhaust fans.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
We are using LED lighting in many buildings, as appropriate. We have installed them in outdoor parking lot lighting, in hallway recessed lighting, in classrooms and in meeting rooms. We are trying a variety of applications to learn more about how and where the products work the best. The Sustainability and Energy coordinators offices are utilizing the LED technology, including optimal color spectrum for learning.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The College opened its first geothermal heated/cooled residential hall in August of 2016, which is outside of this reporting period. We look forward to reporting its data in our next STARS submission.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
The Co-Generation of electricity is heat-load based. We produce high pressure steam to turn the generator which in turn reduces the steam pressure to 45 lb. This medium pressure steam heats water and air to heat campus buildings. The generated power is consumed on campus.
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):
Keene State is engaged with its building operations contractor, Honeywell, to retro-commission its controls across campus to check and confirm that those systems to perform as they should for optimal building performance. When we launched this effort late in 2014, our intention was to deploy this effort in at least three campus buildings each year. Honeywell has already made recommendations for needed upgrades to achieve increased efficiencies in six campus sites.
This project was inspired by USGBC LEED standards that require 5-year rotations of retro-commissioning for new buildings, a standard KSC welcomes in its existing buildings, many of which have never been commissioned since their construction.
