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

This energy consumption baseline was selected in order to match the greenhouse gas baseline approved by U.Va.'s Board of Visitors.


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

The University of Virginia through our Delta Force Retro-commissioning process reviews hte use of facilities and implements timer-based setbacks through our central control systems.

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

UVa has installed LED replacements for CFL and incandescent lamps at several buildings, including Gilmer Hall, the Chemistry Building, Runk Dining Hall, O'Hill dining Hall and Campbell Hall.


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

Most UVa buildings have at least some areas where lighting is control by infrared/ultrasonic occupancy sensors. In many buildings, offices and common spaces are outfitted to occupancy sensors that reduce lighting loads. In our new residence halls,lighting in common areas dims when motion or occupancy is not detected. The University has made a commitment requiring that all new construction be LEED certified. As part of this, the new South Lawn Commons includes daylight harvesting controls as part of its overall Building Automation package.

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

None


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

None


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

The University has completed an Alternative Energy Study, and is beginning a detailed study for combined heat and power. This is a major consideration for two reasons, it will reduce our carbon footprint and also improve overall reliability and customer service.


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

Delta Force is U.Va.’s interdisciplinary team-based approach to optimize the performance and sustainability of the most energy intensive existing buildings on Grounds. Each building’s Delta Force team includes facility coordinators, trades and staff, building occupants, external consultants as needed, and is led by Office for Sustainability Energy Engineers. The Delta Force program has two main goals in planning, implementing and tracking projects. One goal is to select a building and maximize sustainable practices in a cost-effective manner, with a focus on energy and water use. The other goal is to encourage building occupants to maintain and exceed sustainability goals set for the building. The program is funded through actual (metered) utility cost savings from projects implemented through Delta Force. Delta Force projects typically run 12-15 months and include:

A comprehensive assessment of building control systems, including a point-to-point check of all monitored systems including the building automation system (BAS)
An engineering assessment of all HVAC system components, including air handler units, exhaust systems and hoods, enthalpy recovery devices, supply pipes, valves, ducts and air distribution systems
The operation of VAV and terminal boxes throughout the building including area-specific pressurization, air exchange rates and when possible, occupant comfort
Lighting retrofits including the replacement of all 32 Watt T8 fluorescent lamps with 25 Watt lamps that have no more than 2mg of mercury
The installation of water flow restrictors in restrooms


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

All metering and energy / Building Automation Systems (BAS) are monitored at the Energy and Utility Systems Control Center (SCC). While our large number of buildings includes a variety of BAS systems, in both vintage and complexity, the SCC is staffed 24/7/365 to monitor performance, alarms and safety systems for the University.


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

Energy Star equipment and appliances are typically purchased. EPEAT computers are typically purchased.


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:

UVa has installed 216 vending misers on machines throughout the grounds. We will continue to add throughout the coming year.
