A brief description of when and why the building energy consumption baseline was adopted:
The baseline year was adopted because it was the oldest data that we could reliably recover from internal records and through our natural gas and electric provider.
A brief description of any building temperature standards employed by the institution:
The University of Wisconsin-La Crosse complies with the Energy Use Policy available at ftp://doaftp1380.wi.gov/master_spec/Energy%20Guidelines/Energy%20Use%20Policy.docx
This policy is intended to reduce the use of energy from fossil fuels and other sources without adversely affecting program operations. Energy conservation is not a one-time activity or project. It is an on-going responsibility, requiring daily attention and providing daily opportunities. Reducing energy usage helps manage utility budgets and reduce the demand for fossil fuels and generation of related air emissions.
The Policy states:
"C. Heating, Ventilating and Air Conditioning (HVAC)
Thermostats: In small buildings and in exterior zones of large buildings, adjust to 68oF maximum in the winter and 76oF minimum in the summer. Reduce to 60oF during unoccupied winter hours.
In interior variable air volume zones of large buildings, adjust to 76oF minimum.
In interior constant air volume zones of large buildings, adjust to 68oF maximum in the winter and 76oF* minimum in the summer. Reduce to 60oF during unoccupied winter hours. *(For reheat systems, subject to discharge reset control strategy and temperature setting necessary to minimize cooling and reheat.)
In vestibules, stairwells, mechanical/electrical rooms, elevator equipment rooms, unoccupied storage and similar spaces, adjust to 60oF in the winter.
Dress for comfort and plan for the conditions in your working environment.
Ventilation and Air Conditioning: Shut down equipment during unoccupied hours. Use building automation systems or time clocks to automate operations."
A brief description of any light emitting diode (LED) lighting employed by the institution:
The University uses Light Emitting Diodes in all exterior pole and building mounted lighting except for parking surface lot lighting. Parking surface lot LED lights will begin to be installed in summer 2015 with all parking lots being completed in two to three years. An existing parking ramp completed in 2014 has 100% LED lighting.
A new student center under construction and slated to open in fall 2016 will be nearly 100% LED lighting. LED lights are being included in all office remodels. LED lights are installed in almost 100% of emergency egress lighting. LED lights are also being installed in stairwells that require more than a 12 foot ladder to replace existing florescent lighting.
A brief description of any occupancy and/or vacancy sensors employed by the institution:
The University uses occupancy sensors and/or vacancy sensors in two LEED Gold certified buildings with a total gross square footage at 423,050. Occupancy sensors and/or vacancy sensors were installed as part of a campus wide performance contract project in 2005. Locations for these sensors and their installation was coordinated by the performance contract agent.
A brief description of any passive solar heating employed by the institution:
The design of the two LEED Gold certified buildings, with a total gross square footage at 423,050, maximized passive solar heating to the greatest extent practical. Designs factors included but were not limited to how the building was sited, types of window glazing, and types of shades/installed window coverings allowed.
A brief description of any ground-source heat pumps employed by the institution:
The University does not have ground source heat pumps. These systems are included for consideration in all new buildings, but limited budgets and installation sites for wells have resulted in energy conservation efforts being emphasized to increase building operating efficiency.
A brief description of any cogeneration technologies employed by the institution:
The University does not use cogeneration.
A brief description of any building recommissioning or retrofit program employed by the institution:
The University of Wisconsin-La Crosse has buildings that are up to 110 years old. HVACR, plumbing and electrical systems in buildings are periodically updated in buildings as budget, system efficiencies and customer needs dictate. For instance, in the 110 year old building, Graff Main Hall, the 350 occupant auditorium completed a retrofit and recommission project within the past year. In addition, Wittich Hall, an approximate 100 year old building, has an approximate $30 million dollar project to recommission and retrofit the facility; this project is currently in the process of hiring an architectural/engineering firm to complete the redesign.
A brief description of any energy metering and management systems employed by the institution:
The University of Wisconsin-La Crosse uses Andover Systems as its campus-wide energy management system. The system allows for the monitoring and control of environmental conditions in all buildings and allows the scheduling of systems to maximize energy efficiency. We track energy use in all buildings using the web based Energy Watchdog. There are approximately 210 meters being monitored in Energy Watchdog, These meters monitor steam, condensate, electricity, chilled water, natural gas, potable water, and output from the solar domestic hot water heating system.
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
By State of Wisconsin mandate, the University of Wisconsin - La Crosse incorporates energy efficiency into all retrofit and recommissioning projects. These projects generally include any project in excess of $50,000. The University has also adopted internal energy efficiency policy to purchase and then have or Information Technology Department setup power options to maximize energy savings on all campus owned computers. The University Purchasing department also strongly encourages the purchase of Energy Star compliant appliances. As an example, the Office of Residence Life manages approximately 1,800 dormitory size refrigerators; when replaced, they do so with Energy Star certified products.

A brief description of other energy conservation and efficiency initiatives employed by the institution:
On an annual basis the University of Wisconsin-La Crosse updates and submits to the State of Wisconsin a log of energy efficiency projects it desires or is in the process of implementing. For instance, in 2015 some of the projects planned or being completed from the list are as follows. Replace approximately 500 showerheads going from 2.5 down to 1.5 gallons per minute. Replace existing water heating system in last 3 residence halls, 5 halls already completed. This project will replace approximate 2,000 gallon holding tanks with two 100 gallon tanks and a semi-instantaneous water heater. The University will begin a multiyear project to install LED lighting in all surface parking lots. The University is finishing install of BACNET capable control devices and components to provide enhanced control of building HVACR systems.
