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 | 728,428 MMBtu | 753,892 MMBtu |
| Electricity from on-site renewables | 537 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 884,880 MMBtu | 1,074,956 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 193,807 MMBtu | 225,346 MMBtu |
| Total | 1,807,652 MMBtu | 2,054,194 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, 2008 | Dec. 31, 2008 |
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 campus began ramping up energy efficiency efforts in 2008, making it an appropriate baseline year from which to gauge progress.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 16,284,867 Gross square feet | 15,838,197 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 | 0.11 MMBtu per square foot | 0.13 MMBtu per square foot |
| Source energy | 0.22 MMBtu per square foot | 0.25 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
11.24

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):
The Energy Office manages energy usage campuswide to reduce energy costs, optimize building operations and provide feedback on energy usage to building occupants.
The student-run Berkeley Energy Resources Collaborative (BERC) hosts an annual energy symposium.
Residence hall competitions to reduce electricity consumption and bulb exchanges have been held.
Finally, the campus offers an online Energy Dashboard that lets anyone see up-to-date reports on building energy use across the campus.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
An energy management system that controls ventilation, temperature, lights and operating hours is used in buildings on the main campus.
Strategic Energy Program: The SEP is an incentive-based partnership with our local utility, PG&E, and includes monitoring-based commissioning, new lighting and HVAC system upgrades.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The campus installed 800 exterior LED lamps - all of the iconic exterior lampposts - replacing the existing metal halide bulbs. The wattage in these fixtures dropped from 175 to 40 watts.
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):
In 2016, the cogeneration plant on the UC Berkeley campus was operated by a third party, so the electricity generated by the plant is not included here.
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):
Berkeley has won awards for its green buildings and recommissioning efforts. The following is a case study for one of these commissioning projects: http://greenbuildings.berkeley.edu/pdfs/bp2012-mbcx-ucb.pdf
