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

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 586,778.72 MMBtu 548,971.50 MMBtu
Electricity from on-site renewables 44.94 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) 340,611.76 MMBtu 384,682.40 MMBtu
Total 927,435.42 MMBtu 933,653.90 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2019
Baseline Year July 1, 2011 June 30, 2014

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):

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 3,958,394 Gross Square Feet 3,400,760 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.23 MMBtu / GSF 0.27 MMBtu / GSF
Source energy 0.55 MMBtu / GSF 0.62 MMBtu / GSF

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

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 8,245.67 Degree-Days (°F)
Cooling degree days 573.67 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 308,465 Square Feet
Healthcare space 0 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
4,630,435 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
22.71 Btu / GSF / Degree-Day (°F)

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):

Website, interaction with campus, Sustainability Coordinator, articles, promoting energy conservation

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

Night setbacks, equipment scheduling, occupancy sensors

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

The standard across campus is LED lighting. Therefore all new lighting will be LED and in some cases existing lighting is being retrofitted to LED.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

solar wall, solar panels, ground source heat pump,

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):

SDSU does not employ co-generation methods

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):

Only allow energy start equipment when available; all new construction follows LEED standards; remodels include high efficiency equipment
