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 10,481,492 Kilowatt-hours 35,762.85 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) 63,761 Kilowatt-hours 217.55 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):
MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy 105,874 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
141,854.40 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

Baseline period

Start and end dates of the baseline year (or 3-year period):
Start date End date
Baseline period June 1, 2006 May 31, 2007

A brief description of when and why the energy consumption baseline was adopted:
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.

Source energy

Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.09 MMBtu per square foot 0.14 MMBtu per square foot
Baseline year 0.10 MMBtu per square foot 0.15 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:
4.23

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
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:
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:
Hobart and William Smith are participants in the NYSEG Energy Efficiency Program, established by the New York State Public Service Commission (PSC) to create an Energy Efficiency Portfolio Standard to reduce the state’s overall energy consumption and encourage wise energy use. In 2019, staff from Franklin Energy, a certified contractor with the NYSEG program, joined Residential Education and the Office of Sustainability to install upgrades in every student housing option on campus. A total of 185 inefficient lightbulbs were removed and replaced with LEDs that consume only 9 watts of electricity

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. Further, during first-year student move-in, free LED replacement bulbs are given out for use in personal lamps. 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:
The Finger Lakes Institute at HWS is regulated by a geothermal heating and cooling system. A total of 20 wells, drilled to the depth of 100 feet, were installed to use the earth's constant temperature, 55 degrees F, as a heat source or heat sink, depending on the season.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
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.
