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 14,164,826 Kilowatt-hours 48,330.39 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 15,067.30 MMBtu
Imported steam, hot water, and/or chilled water 18,869 MMBtu

Total site energy consumption, baseline year:
82,266.69 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
932,662 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

Baseline period Jan. 1, 2008 Dec. 31, 2008

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 energy

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 per square foot 0.18 MMBtu per square foot
Baseline year 0.09 MMBtu per square foot 0.20 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:
9.41

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:
---

A brief description of energy use standards and controls employed by the institution:
---

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.
