Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | MMBtu | MMBtu |
| Electricity from on-site renewables | MMBtu | MMBtu |
| District steam/hot water (sourced from offsite) | MMBtu | MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | MMBtu | MMBtu |
| Total | MMBtu | 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 | 154,431.91 Gross square meters | 153,336.59 Gross square meters |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.61 MMBtu per square meter | 0.74 MMBtu per square meter |
| Source energy | 1.25 MMBtu per square meter | 1.44 MMBtu per square meter |
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 | 1,801.67 Degree-Days (°C) |
| Cooling degree days | 123.33 Degree-Days (°C) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 16,365.14 Square meters |
| Healthcare space | 609.91 Square meters |
| Other energy intensive space |
EUI-adjusted floor area, performance year:
189,629.42
Gross square meters
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
79.04
Btu / GSM / Degree-Day (°C)

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):
N/A
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.
