Start Date End Date
Performance Year Jan. 1, 2016 Dec. 31, 2016
Baseline Year Jan. 1, 2008 Dec. 31, 2008

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):

All baselines were created in 2008 when the university's first Sustainability plan was written.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 3,512,891 Gross Square Feet 2,856,712 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 0.12 MMBtu / GSF
Source energy 0.15 MMBtu / GSF 0.20 MMBtu / GSF

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

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 6,624 Degree-Days (°F)
Cooling degree days 654 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 243,668 Square Feet
Healthcare space 0 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
4,192,178 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
11.15 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):

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

All buildings have setpoints for temperature that can be monitored and programmed using Johnson Controls Metasys system. Set points set by the University of Wisconsin System are 68 for heating and 75 for cooling.

All academic buildings and recently renovated buildings for student services, student recreation, and facilities management use motion sensors to control lighting. As part of an energy project in 2016 Facilities has implemented sensors to fume hoods in the Halsey Science Center to lower exhaust in the hoods during periods of nonuse. Motion sensors and VAV controls were also added to the Clow Classroom building to reduce supply air cfm when rooms are unoccupied.

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

In 2011, substantial outdoor lighting upgrades were about half LED fixtures and half induction lighting fixtures. LED fixtures were used predominantly in pole lighting along walkways. LED fixtures were also installed in the interior of Blackhawk Commons to replace emergency fluorescent fixtures and metal halide up lighting in the dining areas. The exterior security lighting around the Titan Stadium and the interior lights in the Arts and Communication Center Theatres were changed to LED.

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

Sage Hall and Horizon Village both use passive solar heating with time controlled shades. The campus also has 5 solar thermal installations. 1) Albee, heats the water for the olympic size indoor pool 2) Taylor Hall, heats the domestic water for the residence hall showers 3) Blackhawk Commons also heats the domestic water 4) Heating Plant to preheat the makeup water for the central boilers system 5) Sage Hall uses the solar for heating domestic water and building heating system.

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

The university has one biodigester located on campus and two more in the community. Heat is generated along with methane gas as organic matter breaks down. The methane gas is stored and then later burned off for energy which is then sold back into the grid.

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):

All appliances in the dining services including refrigerators and dish washers have been replaced with Energy Star efficient models. The HVAC system was retrofitted in 2011. All computers purchased for replacement by the University are required to carry the Energy Star certification.
