Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 100,681 MMBtu | 188,986 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) | 106,824 MMBtu | 163,173 MMBtu |
| Total | 207,505 MMBtu | 352,159 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, 2009 | June 30, 2010 |
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):
The baseline year of fiscal year 2009-2010 was selected to provide a 5 year comparisson.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 4,307,021 Gross square feet | 3,852,144 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 | 0.05 MMBtu per square foot | 0.09 MMBtu per square foot |
| Source energy | 0.10 MMBtu per square foot | 0.20 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
50.00

Optional Fields

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):
SF State uses an energy dashboard to display usage on an individual building and whole campus basis. Building managers can use this feedback to adjust management strategies and educate their inhabitants. SF State's Facilities department monitors usage and checks on any spikes or anomalies in data to find opportunities to repair issues or replace inefficient equipment.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
SF State's Facilities department uses a computer program to monitor HVAC systems energy performance throughout campus.
SF State uses occupancy sensors for lighting throughout campus. New lighting installations include daylight harvesting and central controls.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
SF State has begun to retrofit campus lighting from fluorescents to LEDs that include features like daylight harvesting, motion sensors, central controls, and timers. Spaces on campus that use LED lighting include: the SF State Parking Garage, Fine Arts Gallery, President's Office, Facilities office, Capital Planning Office, waste management, and interior and exterior lighting at the Mashouf Wellness Center.
SF State uses motion sensors throughout campus buildings to reduce energy consumption from lighting.
SF State employs delamping as a method for lowering lighting energy use by removing excessive lighting.
SF State's newer buildings use daylighting to reduce the need for mechanical lighting.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
n/a
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
SF State operated 2 cogeneration plants until 2012 when they were decommissioned. Part of the reason SF State left them in non-operation was to decrease greenhouse gas emissions from natural gas and to move towards a zero-emissions campus.
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 SF State Sustainable Development Framework requires all contractors to specify energy efficient appliances in new construction and in building retrofits.
