Grid-purchased electricity 37,679.37 MMBtu 35,737 MMBtu
Electricity from on-site renewables 208.01 MMBtu 208.01 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) 108,908 MMBtu 105,666 MMBtu
Total 146,795.38 MMBtu 141,611.01 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year June 1, 2016 May 31, 2017
Baseline Year June 1, 2006 May 31, 2007

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):

Past HWS President Mark Gearan signed the ACUPCC in September of 2007. Based on this, HWS established fiscal year 2007 (FY07), the year just prior to signing the commitment, as the standard baseline year for all sustainability indicators for which data is available.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 1,523,838 Gross square feet 1,446,386 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 0.10 MMBtu per square foot 0.10 MMBtu per square foot
Source energy 0.15 MMBtu per square foot 0.15 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 5,683 Degree-Days (°F)
Cooling degree days 898 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 96,690 Square feet
Healthcare space 0 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
1,725,368 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
12.93 Btu / GSF / Degree-Day (°F)

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):

HWS Eco Reps host a number of events promoting the competition and encouraging students to reduce their electricity usage. From board game nights to environmental-themed movie showings and a “Lights out on the Night Out” event encouraged students to turn off their electronics and lights in residence hall rooms. In previous years, the Colleges have participated in the New York Negawatt Challenge, a three-week competition among schools in the New York Six Consortium to reduce electricity usage. We hope to restart this program next year.

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

The Colleges’ campus-wide Building Automation System (BAS) maintains a heating set point policy of 68-72 degrees and cooling set point policy of 74-78 degrees.

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

Since 2016 100% of all light-bulb replacements are done with LED lights when possible. When fixtures or ballasts are not compatible the most efficient fluorescent bulbs are used. The Colleges’ LED program has also replaced numerous fixtures. LEDs are considered for every lighting upgrade. In 2014 and 2015, LEDs were installed in 578 emergency lights, 240 fixtures in student rooms, 25 exit lights, 18 parking lot pole lights, and 40 troffer style lights in the library archive. The Gearan Center for the Performing Arts, which opened in January 2016, includes interior and exterior LEDs.

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

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


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 Colleges conduct a building re-commissioning program aimed at improving mechanical system performance and reducing energy consumption on an annual basis. Most buildings use more energy than necessary to provide a safe and comfortable environment for the occupants. Over time, building systems typically become less efficient as components wear out and building usage changes. A re-commissioning improves a building’s energy efficiency.
