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

Most recent emission year that has been third-party verified. This baseline most accurately represents current state of campus in terms of GSF and enrollment.


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

Every permanent building on campus used schedule to regulate temperatures and ventilation rates based on occupancy hours. On a weekly basis, a script has been created that automatically reviews campus schedules for events and classes and schedules individual building areas to come for any event that are outside of after weekday scheduled hours.


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

The campus installed LED lighting for a 3.5 acre parking lot on campus in 2012.


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

Every permanent building on campus uses motion, infrared, and/or light sensors to reduce energy use. Typically office building use dual-sensor occupancy sensors, common areas are controlled by schedule, and exterior lighting is controlled by a centralized astronomic clock.


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

A solar water heater is installed on the rooftop of our Science and Engineering 2 building.


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:

The campus continually monitors the commissioned systems and energy consumption of all buildings through the buildings energy management system. Central Plant control room is where all buildings are monitored by technicians on staff 24 hours a day. In addition, since all buildings are LEED certified, a full system review of building operation is performed 10 months after substantial completion to ensure it is operating as designed. A re-commissioning manual or systems manual is provided to facility staff at building turnover.


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

All campus mechanical, electrical, lighting are controlled and monitored using an Automated WebCTRL energy management control system. All campus electricity and gas use is further tracked using a custom Energy Performance Platform.


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:

The campus uses an Evapo-transpiration (ET)-based controller from Tucor on our irrigation system. ET is a combination of water lost from plant material through evaporation (from the ground) and transpiration (from the leaves, etc.). The system is programmed with a base ET rate that dictates how long to run and how much water is put down. The ET rate is a function of local climate zone and the type of plant material being irrigated (e.g. turf grass will have a different ET rate than shrubs). Our controller is linked to a weather service that looks at the previous day's ET rate for our area and automatically makes adjustments to the sprinkler run times as required.


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

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

An event known as the “Cool Campus Challenge” was an online learning experience and competition between UC campuses running for about two months. It’s designed to motivate and reward staff, faculty and students who take steps to reduce their carbon footprints and help the UC system reach Carbon Neutrality by 2025. The UC Merced Powersave Program is a campus group consisting of student interns and volunteers that develop and implement programs and events associated with water conservation, energy efficiency, green workforce development and academic outreach.
