A brief description of when and why the building energy consumption baseline was adopted:
---

A brief description of any building temperature standards employed by the institution:

Building thermostat set points are 78F for cooling/68F for heating. At 11:00 PM, where building systems permit, thermostat set points are remotely adjusted to 60F for heating and 85F for cooling. Exceptions are made only for certain buildings with tighter temperature requirements. Buildings will return to their day operating mode by 7:00 AM daily.


A brief description of any light emitting diode (LED) lighting employed by the institution:

LED lighting systems are currently used in the following spaces: Walsh Administration Conference Room, Support Services Parking Lot, Exterior Lighting.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

Daylighting controls are used for exterior exposures in Support Services, Bannan Labs, Learning Commons, Lucas Hall, Heafy Law Library, Benson Memorial Center, Casa Italiana.


A brief description of any passive solar heating employed by the institution:

A 60-collector solar thermal system was installed on top of the Benson Memorial Center in 2010. The Chromasun MCT panels produce an estimated 6,700 therms of energy annually and heat water to 200 degrees Fahrenheit for Benson Memorial Center’s dining services. Heating water with solar energy rather than with natural gas will reduce the building’s water-heating bills by as much as 70 percent and offset 34 tons of CO2, equivalent to the total emissions produced annually by 6.6 automobiles.

The collectors ware manufactured at a Chromasun facility in San Jose, CA. The workforce at this facility includes former New United Motor Manufacturing, Inc. (NUMMI) autoworkers that were re-trained as solar manufacturing experts after the NUMMI facility closed and put back to work building Chromasun modules.


A brief description of any ground-source heat pumps employed by the institution:
---

A brief description of any cogeneration technologies employed by the institution:
---

A brief description of any building recommissioning or retrofit program employed by the institution:
---

A brief description of any energy metering and management systems employed by the institution:

The Energy Maintenance System allows Utilities to control various mechanical systems throughout the University; including heating, air conditioning, lighting, and indoor air quality from a central computer. Controlling these items from a centralized location prevents extreme temperatures within rooms and conserves energy.


A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
---

A brief description of any energy-efficient landscape design initiatives employed by the institution:
---

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

Santa Clara University has 22 sensor vending machines, located throughout campus.


A brief description of other energy conservation and efficiency initiatives employed by the institution:

Upgrading lighting with newer, more energy efficient fixtures saves energy and money. The payback on these upgrades is typically 2-3 years. Lighting has been upgraded in the Heafey Law Library, Orradre Library, residence halls, and Bannan Engineering.
