12.99 Btu / GSF / Degree-Day (°F)

Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	34,507,335 Kilowatt-hours	117,739.03 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	0 Kilowatt-hours	0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	300,605.43 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

418,344.46 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

3,286,082 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	Jan. 1, 2008	Dec. 31, 2008

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

Campus Climate Action Plan was written in 2008. Although the Access Campuses were not yet merged with the Oshkosh campus, they are included here using data from WI State Energy Report records.

Source energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.11 MMBtu per square foot	0.18 MMBtu per square foot
Baseline year	0.13 MMBtu per square foot	0.20 MMBtu per square foot

Metric used in scoring for Part 2

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

14.18

Optional Fields

Documentation to support the performance year energy consumption figures reported above:

---

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

---

A brief description of energy use standards and controls employed by the institution:

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-sized 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:

The university has one biodigester located on campus and one 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 electricity 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:

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.
