Figures needed to determine total building energy consumption:
Performance Year | Baseline Year | |
Grid-purchased electricity | 413,480.60 MMBtu | 411,871.90 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) | 410,017 MMBtu | 342,851 MMBtu |
Total | 823,497.60 MMBtu | 754,722.90 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date | End Date | |
Performance Year | Sept. 1, 2016 | Aug. 31, 2017 |
Baseline Year | Sept. 1, 2011 | Aug. 31, 2012 |
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):
"Baseline year selected based on the context of the State Energy Conservation
Office (SECO) mandated SB 898 report"
Gross floor area of building space:
Performance Year | Baseline Year | |
Gross floor area of building space | 7,915,438 Gross square feet | 7,102,422 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 | 0.10 MMBtu per square foot | 0.11 MMBtu per square foot |
Source energy | 0.22 MMBtu per square foot | 0.23 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 | 953 Degree-Days (°F) |
Cooling degree days | 3,453 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
Floor Area | |
Laboratory space | 132,827 Square feet |
Healthcare space | 7,601 Square feet |
Other energy intensive space |
EUI-adjusted floor area, performance year:
Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
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):
Energy Conservation Committee (ECC) consists of student(s) and staff that work together to disseminate useful energy conservation techniques to the San Marcos community members. Currently, the ECC is working with University Seminar (freshman requisite course) to create talking points addressing this that can be inserted in the course's existing syllabi.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Automatic light sensors on new buildings, buildings minimum and maximum temperatures set to energy efficient temperatures.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
All new and future buildings are fitted with LED lighting and all parking garages and
some classrooms were retrofitted with LEDs. Use LEDs when replacing lighting all around campus.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
0
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
0
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):
Two building were retrofitted and data indicates that they are now more efficient.
