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

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 48,001 MMBtu 49,795 MMBtu
Electricity from on-site renewables 2,923 MMBtu 2,138 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) 140,993 MMBtu 144,398 MMBtu
Total 191,917 MMBtu 196,331 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, 2004 June 30, 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):
Energy data is available back to 1990. FY 2005 was chosen as a modern base year in our last submission and will continue to be used.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 2,114,320 Gross square feet 1,683,474 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 0.09 MMBtu per square foot 0.12 MMBtu per square foot
Source energy 0.14 MMBtu per square foot 0.18 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 6,115 Degree-Days (°F)
Cooling degree days 641 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 111,867 Square feet
Healthcare space 10,803 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
2,359,660 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
12.04 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):
Through the Sustainability program and the Eco-reps, energy conservation is a major education initiative among students and faculty/staff. The Eco-reps run an annual energy competition in the residence halls and provide eco-orientation to all new faculty and staff which includes information on energy use. The College provides free LED bulbs for task lighting for all students, faculty and staff.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Campus wide use of Building Automation Systems including: Andover Controls and Automated Logic Systems are used for building occupancy scheduling. MHC's Heating and Cooling Policy details target daytime and nighttime heating temperatures for academic and administrative areas and residence halls. The master space schedule is used to program heating and cooling times in each space throughout the day depending on occupancy.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The campus has a site lighting replacement plan which includes replacing lights with LED lighting. This plan is currently deployed at approximately 25% for interior lighting. Exterior building lighting is at 98% LED.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Solar hot water was installed on our newest residence hall and provides about 30% of the hot water needs of the hall. Solar hot water is also being installed on the new Community Center currently under construction.

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
Backpressure steam turbine is a co-generation system using steam created by oil or natural gas to generate electricity before being distributed for heating purposes.

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):
The new Community Center under construction will consolidate our 6 current dining locations providing new energy efficient equipment for dining operations and retiring 20 year old inefficient equipment. Additionally refrigeration at the new facility with be a central rack compressor system improving efficiency over the typical single compressor per unit and all exhaust hoods with be variable velocity controlled by heat and smoke sensors.

As mechanical equipment is replaced due to failure it is routinely replaced with energy efficient equipment.
