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

To stay consistent with GHG tracking in AASHE STARS. As a state agency, the Seattle Colleges (including South Seattle College) are required to report annual greenhouse gas emissions in compliance with the State Agency Climate Leadership Act. This act, passed in 2008, established greenhouse gas baseline dates and greenhouse gas reduction targets for all state agencies (2005 baseline for Seattle Colleges). However, we have set our GHG and energy baseline as 2008 for STARS considering the following; 1) this act was not passed until 2008, 2) we did not actively track or take any significant actions to mitigate our GHG emissions or utility usage until 2008, and 3) data reporting and tracking was not systematized until 2008.


Source-site ratio for imported electricity:
3.14

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.08 MMBtu / GSF 0.18 MMBtu / GSF
Baseline year 0.09 MMBtu / GSF 0.20 MMBtu / GSF

Percentage reduction in total source energy consumption per unit of floor area from baseline:
9.41

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

We have photocell LED technology in the cafeteria area in the main building. A major LED retrofit project was complete in Broadway Edison building (457,017 sq. ft.). The project estimated 624,132 kWh savings annually (2018). In Science and Math building, we have lighting sensor using Lumen technology. The parking garage has LED lighting for exit signs and for the bike locker area.
