Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 16,353,745.21 Kilowatt-hours | 55,798.98 MMBtu |
| Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems) | 356,837 Kilowatt-hours | 1,217.53 MMBtu |

A brief description of when and why the energy consumption baseline was adopted:
Baseline year 2018-2019 (pre-pandemic)
Performance year 2020-2021 (pandemic; campus closed...mostly)
HDD/CDD: https://portfoliomanager.energystar.gov/pm/degreeDaysCalculator (using 95358 zip code)
On site energy production data is still in progress. We have a solar production system on west campus (311kW). Projected ideal production is 489.7 MWhr. Estmating usages (without direct measurement) is difficult due to inverter failures ongoing throughout period as well as intermittent cleaning. Working on recovering meausred power output.

Optional Fields
A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
In an effort to achieve cost savings through reduced energy use, the District implements a four (4) day/ten (10) hours per day (Monday through Thursday) work week for the all non-instructional staff during the summer session.
A brief description of energy use standards and controls employed by the institution:
We are currently (as of 10/28/22) in the process of seeking approval for a common building temperature standard across our campuses.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Using grant funds, all outdoor lighting (except light standards at the football/track stadium) was converted to LED.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Yosemite Community College District (YCCD) has an ongoing energy management program. As new technologies become available, the District integrates those technologies that are cost-effective, energy-efficient measures.
Mechanical systems are continually replaced on a rotational basis with the latest energy-efficient systems. With the addition of new or replacement chillers, we are using Turbo Core technology. With the use of Prop 39 dollars and District electrical staff, the District is retrofitting interior and exterior lighting and controls. The YCCD has received approximately $2,744,637 from Proposition 39, incentives, and rebates due to the lighting upgrades.
YCCD has also taken advantage of incentives made available through the California Community College/Investor Owned Utilities (CCC/IOU) partnership. Using these incentives has allowed the District to invest in energy efficient pool covers and HVAC systems.
Funds used from our local general obligation bond were dedicated to upgrading our energy management program. We now use the latest technology to control our HVAC systems and are achieving utility cost savings as a result. Roof replacements district-wide specify a white, single-ply coating that is heat reflective, thereby reducing energy usage. Electric Vehicle Charging Stations were installed in two parking lots at Columbia College and one parking lot at Modesto Junior College, with more planned for the near future.

Data source(s) and notes about the submission:
The choice of a pre-pandemic baseline year (2018-2019) followed by a 'syn-pandemic' performance year (2020-2021) resulted in a temporary reduction in total energy consumption per floor area of approx. 18%. This savings is viewed as being almost completely due to the pandemic closing of campus and should not necessarily be viewed as the result of any intentional energy saving effort.
