"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 29791.60 MMBtu 28704.40 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 14466.70 MMBtu 18012.40 MMBtu
Total 44258.30 MMBtu 46716.80 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):

Calendar year 2007 represents the first year for which South Seattle has accurate data for many of the measures used for our greenhouse gas inventory. Therefore, we are using calendar year 2007 as a baseline for all energy-related measures.


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 623060 Gross Square Feet 574647 Gross Square Feet

Source-site ratio for grid-purchased electricity:
3.14

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.07 MMBtu / GSF 0.08 MMBtu / GSF
Source energy 0.17 MMBtu / GSF 0.19 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
7.88

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 3828 Degree-Days (°F)
Cooling degree days 292 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 81056 Square Feet
Healthcare space 0 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
807500 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:

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):

Timers are used in all academic instruction buildings to maintain temperature only during normal instruction hours. Manual overrides exist on timers.


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

LED lighting has been applied in the north parking lot for all lamp fixtures. LED lighting is also used in some small in-building applications. New lighting retrofit projects are likely to use 100% LED lights indoors.


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):
---
