Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):
kWh MMBtu
Imported electricity 18,686,147 Kilowatt-hours 63,757.13 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 0 Kilowatt-hours 0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 33,568 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
97,325.13 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
1,222,329 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period July 1, 2013 June 30, 2014

A brief description of when and why the energy consumption baseline was adopted:
The energy consumption baseline was adopted in January of 2015 when the university entered into a contract with Cenergistic for energy management. The 2013-2014 fiscal year was the most recent complete data set at the time of the contract.

Source energy

Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.06 MMBtu per square foot 0.14 MMBtu per square foot
Baseline year 0.08 MMBtu per square foot 0.18 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:
25.52

Optional Fields 

Documentation 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:
Initiatives to change energy practices include messaging through announcements, articles, direct contact (ex. residential life emails, texts, etc.) and through interaction at students activity fairs, giving presentations to various user groups and by being a guest presenter in classes.

A brief description of energy use standards and controls employed by the institution:
Campus wide energy guidelines have been put in place that include heating and cooling setpoints of 68°F and 75°F. Occupancy schedules on automated buildings have also been streamlined to reflect actual class and event schedules. Occupancy sensor have been installed in new construction and retrofitted in some existing buildings.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The university has achieved about a 90% conversion of all indoor fluorescent lighting to LED replacement bulbs and/or fixtures. Exterior lighting has been replaced with LED as fixtures have failed or become low performing. All new construction is built using only LED.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The Student Recreation Center (Hollis Center) utilizes roof mounted panels that help supplement the heating of the swimming pool, reducing the amount of natural gas required.

A brief description of co-generation employed by the institution:
---

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The university has made a substantial investment to serve buildings with centrally produced chillwater, replacing hundreds of independent air-cooled chillers and refrigerant cooled compressors throughout the campus and reducing the overall consumption of energy. The central chillwater plant currently supplies to HVAC equipment serving just under 1,000,000sqft. Expansion will occur in the next performance year to serve both new construction and existing buildings.
Most computer labs have been converted from individual computers to virtual interfaces, reducing consumption and heat load in each area.
