None
A brief description of when and why the building energy consumption baseline was adopted:
Baseline for all STARS reporting (except Water Use) is FY 2013-14.
None
A brief description of any building temperature standards employed by the institution:
70-76 degrees fahrenheit
None
A brief description of any light emitting diode (LED) lighting employed by the institution:
LED lighting has been employed in Parking Structures B, C and D, Welcome Center, Salazar Hall, Simpson Tower, the perimeter of Paseo Rancho Castilla, the first floor of the library, and various classrooms throughout King Hall, Golden Eagle and the Wallis-Annenberg Science Complex.
None
A brief description of any occupancy and/or vacancy sensors employed by the institution:
Occupancy sensors are located throughout Salazar Hall and approximately 90% of all other classrooms throughout campus.
None
A brief description of any passive solar heating employed by the institution:
The nine original campus buildings demonstrate passive solar buildings principles that retain solar heat in the winter and reject solar heat in the summer, including window overhangs and cool roofs. Window overhangs on south-facing windows allow winter sun in, while keeping summer sun from overheating buildings. A cool roof is one that has been designed to reflect more sunlight and absorb less heat than a standard roof.
None
A brief description of any ground-source heat pumps employed by the institution:
None
None
A brief description of any cogeneration technologies employed by the institution:
None
None
A brief description of any building recommissioning or retrofit program employed by the institution:
Salazar Hall (Winter 2015 - Fall 2016) will have major lighting, mechanical equipment and automation system programming upgrades as part of a facility modernization. The lighting has been upgraded to LED, the zone boxes have been upgraded from constant-volume dual duct boxes to dual-damper variable air volume boxes, and the building automation system programming will be updated to use DDC zone feedback to optimize air handler operation. Estimated annual energy savings: 629,722 kWh and 75,743 therms. Estimated greenhouse gas emission reductions in metric tons CO2e (using the kWh and therm savings above and the 2013 LADWP emissions factor of 1097 lbs/mWh and 13.44 lbs/therm) the annual CO2 emissions reductions are projected to be 775.27 metric CO2e.
Cal State is also engaged in an MBCx project for the Energy & Technology building. The primary objectives are to: 1) obtain cost-effective savings from implementing low cost measures and optimizing how the building’s energy using systems are operated and maintained, 2) identify previously unrecognized inefficiencies in building and plant system operations, 3) measure and document energy savings from resulting operational improvements, 4) enhance building system performance and building comfort, and 5) facilitate ongoing recommissioning of systems to ensure persistence of savings.
None
A brief description of any energy metering and management systems employed by the institution:
Johnson Controls Metasys Building Automation System and SkySpark Analytics Software by SkyFoundry
None
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
Facility modernization throughout campus, including major lighting, mechanical equipment and automation system programming upgrades. Lighting is being upgraded to LED, zone boxes are being upgraded from constant-volume dual duct boxes to dual-damper variable air volume boxes, and the building automation system programming is being updated to use DDC zone feedback to optimize air handler operations.
None
A brief description of any energy-efficient landscape design initiatives employed by the institution:
The strategic placement and selection of shade trees in Housing and throughout campus helps regulate building temperatures.
None
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
None
