Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 46,694.40 MMBtu 50,012.42 MMBtu
Electricity from on-site renewables 1,753.33 MMBtu 2,394.98 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) 45,033.86 MMBtu 61,209.58 MMBtu
Total 93,481.59 MMBtu 113,616.98 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, 2017
Baseline Year July 1, 2013 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 1,662,292 Gross square feet 1,650,502 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 0.06 MMBtu per square foot 0.07 MMBtu per square foot
Source energy 0.12 MMBtu per square foot 0.13 MMBtu per square foot

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 3,243 Degree-Days (°F)
Cooling degree days 222 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 176,153 Square feet
Healthcare space 6,565 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
2,041,155 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
13.22 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):

During winter, spring, and summer break there are a series of all staff e-mails that serve as a reminder to clean out and unplug all appliances (plug loads) that will not be used over break. The e-mails mention behavior change and saving energy, GHG reduction, and utility savings. Additionally the Eco-Cub Department Certification promotes sustainable behaviors all departments can do and showcases departments who are already excelling at sustainable practices.

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

The college's Facilities Master Plan requires all new buildings and major renovation to meet specific Zero Net Energy Source Energy Use Intensity Standards. This requires the buildings to focus on maximizing daylight, minimal LED lighting, high insulation, plug load controls, Energy metering, HVAC controls, and using geothermal condensing water systems to promote electrification.

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

The institution has LEDs installed in many of the buildings throughout the district. New Control systems such as occupancy sensors, dimming, whole building shutoff sweeps and dimming.

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

There is a Geothermal pump heating/cooling system installed at Bertolini Student Center. This system includes 148 wells that are six inches in diameter that run under Burbank Circle circulating 55 degree water. New construction is focusing on adaptability and resilience by increasing all insulation to R40 roof and R20 walls. This passive design strategies accounts for the expected increase in Cooling Degree Days due to changing climate.

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):

The college participates in PG&Es' retro-commissioning and monitoring based commissioning programs and does internal audits of appliances to identify when things can be upgrades and centralized during break shutdowns.
