Part 1
This credit is based on energy inputs from offsite sources and electricity produced by onsite renewables. When the institution purchases one fuel and uses it to produce heat and/or power, you should enter only what is purchased. For example, if the institution purchases natural gas to fuel a CHP system and produce steam and electricity, only the purchased natural gas should be reported.
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 1,120,803.10 MMBtu | 1,067,224 MMBtu |
| Electricity from on-site renewables | 61.38 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 954,161.20 MMBtu | 898,780 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 2,203,128 MMBtu | 1,431,131 MMBtu |
| Total | 4,278,153.68 MMBtu | 3,397,135 MMBtu |

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
The over 500 existing buildings at U.Va. present continual opportunities for sustainability upgrades. In addition to the primary existing buildings sustainability program, Delta Force, Facilities Management, with the help of student workers, continues to identify and upgrade inefficient lighting fixtures throughout the University. This year eight facilities were selected for full building re-lamping. In addition, 155 exterior pole lights, bollards & other exterior lights were converted to LED. These projects saved the University $97,300 in electricity costs in 2014-15 because they were completed mid-year. These lighting projects are estimated to save the University over $130,000 annually.
Delta Force is a building efficiency initiative led by a team of engineers in Facilities Management. Since 2007, $7.9 million has been invested in the Delta Force retro-commissioning initiative. With an avoided cost to date of nearly $22 million, the simple return on investment is 2.5:1 since the program inception.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies 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 passive solar heating, geothermal systems, and related strategies employed by the institution:
None
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
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 detailed co-gen analysis and feasibility study is currently being conducted by Jacobs engineering.
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):
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
