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

Oldest data available, attempting to have consistent baseline throughout report

A brief description of any building temperature standards employed by the institution:

A brief description of any light emitting diode (LED) lighting employed by the institution:

Over 1600 screw in (medium base) lamps deployed in the last 3 years. Several hundred recessed LED fixtures install since 2010. Approx. 900 T-10 LED tube lamps installed FY13/14.

LED exit signs were installed in John M. Green Hall. They had to be custom ordered because these signs were built into the existing millwork in an architecturally-sensitive location

A brief description of any occupancy and/or vacancy sensors employed by the institution:

Approx. 10% of space has occupancy sensors.

A brief description of any passive solar heating employed by the institution:


A brief description of any ground-source heat pumps employed by the institution:


A brief description of any cogeneration technologies employed by the institution:

3.5 MegaWatt Solar Centaur 40 gas combustion turbine that supplies all of Smith's heat and a large portion of its electricity.

A brief description of any building recommissioning or retrofit program employed by the institution:

Most recently retro commissioning approx. 1,300,000 gsf in 12 buildings FY 13/14

A brief description of any energy metering and management systems employed by the institution:

Automated logic building controls in approx. 2/3's gsf. Electric and water meters in approx. 2/3's gsf. Gas meters in all buildings with gas. Steam and Chilled water meters in 20% gsf.

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

Smith College encourages the use of "Energy Star" appliances and purchases them for its operations.

Energy Star Policy:

A brief description of any energy-efficient landscape design initiatives employed by the institution:

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

Vending machines must be Energy Star.

A brief description of other energy conservation and efficiency initiatives employed by the institution:

Smith College has an MOU with National Grid, its electricity supplier, to reduce consumption by 15% over 3 years.

Students, faculty and staff changed the settings on their computers in order to save energy in The Million Monitor Drive campaign. Each individual contribution added up to savings of $60,000 and 520 tons of carbon dioxide each year.
