Baseline Year July 1, 2005 June 30, 2006

A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 6,408,406 Gross Square Feet 4,670,562 Gross Square Feet

Source-site ratio for grid-purchased electricity:

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.10 MMBtu / GSF 0.13 MMBtu / GSF
Source energy 0.20 MMBtu / GSF 0.25 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:

Laboratory space 83,287 Square Feet
Healthcare space 9,737 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
6,815,247 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
20.30 Btu / GSF / Degree-Day (°F)

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):

Many projects are conducted with an in-house technician retrofit the existing lighting systems to more efficient ones using Light Emitting Diode LED lamps. In 2016, an outside contractor retrofitted to LED all the lights in 1100 West Market building and half of them for the Music Building. In the year after, the same effort of spreading LEDs on campus is continued, but, with a different approach. The new approach is using the in-house technicians to perform the LED retrofit outside working hours on Saturdays with an overtime rate. The new approach exceeds the expectations by not only having the LED's advantages but also, cutting to the 1/3 the budget if performed by an outside contractor. The other 50% of the Music Building and all of Campus Supply Store lights have successfully retrofitted to LEDs in 2017. In 2018, more six other projects in five buildings on campus are planned to using the in-house approach.

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

As part of the Standards of Comfort program started in December 2011Using, many buildings on campus follow occupancy schedules program through controlling temperature during unoccupied hours through upper and lower limit setpoints by the Building Automation System (BAS). Buildings not on the BAS are also being incorporated into this program, as Facilities staff must manually adjust the settings in these non-BAS buildings each season and install thermostat locks to prevent occupants from changing these settings. All of the buildings on campus have a locked thermostat; the University will continue this approach with any new building and or space added.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

In FY2016-17, the University continued progress in replacing exterior site lighting with LEDs and installed additional site lighting at three locations Peabody Park, Foust Park, and McIver Mall. In the Foust Park, eleven (11) high-pressure sodium poles have replaced with LEDs using the student fee-funded Green Fund. The University is continuing to replace all exterior lights to LED in a multi-year phase project using student’s Green Fund.
The University continues to replace incandescent, compact fluorescent and metal halide lamps with LED were possible for both outdoor and indoor light fixtures.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):

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):

In an effort to improve the efficiency of HVAC systems on campus, since FY 2015-16 The University completed three hundred eighty-four (384) hours of contract retro-commissioning for twenty-six (26) buildings on campus. This effort would continue by the Controls Shop with an in-house retro-commissioning for other building on campus.as needed
