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

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 22,496 MMBtu 27,399 MMBtu
Electricity from on-site renewables 1,253 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) 42,810 MMBtu 39,529 MMBtu
Total 66,559 MMBtu 66,928 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, 2003 June 30, 2004

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 building energy consumption FY2004 baseline was chosen because Sightlines data analysis for facilities and GHG emissions started in that year. This baseline is used throughout relevant credits in the Operations section.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 802,800 Gross Square Feet 801,895 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 0.08 MMBtu / GSF 0.08 MMBtu / GSF
Source energy 0.14 MMBtu / GSF 0.16 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 6,200.80 Degree-Days (°F)
Cooling degree days 1,080 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 22,100 Square Feet
Healthcare space 0 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
859,000 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
10.64 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):

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

The College uses a digital building automation system (BAS) for most buildings on campus. Hampshire does have setback policies that shut down cooling after 8PM, on the weekends and during scheduled shutdown periods. Energy policy seats the cooling setpoint at 74 to 78 degrees, and the heating setpoint at 68 to 71 degrees.

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

A comprehensive LED lighting program has been underway for 5 years, replacing both indoor and exterior lighting with LED. Corridors and stairwells have been retrofit with bi-level lighting that senses occupancy, dimming to minimum code-required levels when these spaces are vacant.

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

The 250-bed Merrill Dorm was renovated in summer 2015, replacing its electric resistance heat with variable-flow refrigerant (VRF) air-source heat pumps.

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

Two 35-year-old cogeneration units, located in Dakin Dorm, had to be dismantled as part of the solar project. This was due to a technicality and unfortunate interpretation of the state's net metering laws. These units were still operating until May 2017, at 82% overall efficiency, making electricity and domestic hot water for two dormitories and a dining hall.

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):

Hampshire College is committed to stewarding its facilities. Given the age of campus buildings, many critical building component lifecycles are coming due. As a result, the College is reinvesting in its buildings and where possible improving campus energy efficiency in the process.

Hampshire participated in the Massachusetts Green Colleges initiative, a paid-from-savings program to install LED lighting and variable speed drives on HVAC units.

Additional documentation to support the submission:

Laboratory area is 2.5 floors of the Cole Science Center. Other energy-intensive space is the natatorium.

Solar PV on-line in FY2017 includes Liebling Center (5.4 kW), Arts Village (39.6 kW), president's house (14 kW), CSA Barn (17 kW), and Kern Center (99 kW). One large solar field (1797 kW) was partially on-line for two months.
