Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 43975 MMBtu 42689 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 13140 MMBtu 19668 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 15492 MMBtu 6267 MMBtu
Total 72607 MMBtu 68624 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Jan. 1, 2016 Dec. 31, 2016
Baseline Year Jan. 1, 2005 Dec. 31, 2005

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):

To stay consistent with our GHG inventories. As a state agency, the Seattle Colleges (including Seattle Central 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).

Documentation (e.g. spreadsheet or utility records) 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 (e.g. outreach and education efforts):
---

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

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.
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.


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):
