Green Revolving Fund

You are here

The UMD Green Revolving Fund was established to invest in sustainable projects at UMD. Projects are intended to contribute to efforts to save energy and become a more sustainable campus, along with providing long-term financial savings to the University of Minnesota. Savings and rebates are paid back into the fund, building equity, and helping to fund future projects.

In 2011, UMD Facilities Management provided $100,000 seed money from utility savings to support the Green Revolving Fund. Energy rebates obtained by UMD Facilities Management are also provided back to the Fund, to serve campus and invest in future energy savings. UMD Economics student Stacy Gerths was instrumental in getting the fund established, through a Sustainable Development Research Opportunity Project.

With innovative efforts from students, faculty, and staff from across the UMD campus, together we can help lower campus emissions to 25% of 2007 levels by 2020 and operate a carbon neutral campus by 2050, as outlined in UMD’s Energy Action Plan.

What are the goals of the Fund?

The Green Revolving Fund’s primary goals are to reduce the campus carbon footprint, help UMD save money, help educate the campus community about sustainability issues, and to help increase interdisciplinary connections throughout campus. Proposals are evaluated by the Office of Sustainability and by the Sustainability Committee.

Who can apply?

Any UMD student, staff or faculty member may apply for Green Revolving Funds. Student applications require a faculty or departmental advisor, to help in managing fund appropriations.

Funded Projects

Solar Photovoltaics on Oakland Apartments  – Coming Soon!

The UMD SUN Delegation led an effort to increase solar electricity production at UMD.  Originally, the group designed a solar pavilion.  When construction was halted due to poor soils, the project was re-imagined to be flat-mounted solar on a south-facing roof of Oakland Apartments.  Money from the Green Revolving Fund will be used in conjunction with $100,000 from a Student Service Fees to install the solar array, along with matching funds from UMD Housing and Residence Life.  The additional solar energy will help to reduce the University’s carbon emissions and reach goals outlined by the University’s Energy Action Plan.  The project will visibly demonstrate UMD’s commitment to sustainability.

Environmental Conditioning Unit Replacement at NRRI

-  _  _

A precision air conditioning unit has been replaced in a mechanical testing room at NRRI. This room is used for a variety of mechanical destructive and non-destructive tests for both research and external sales clients and requires precise control of the room’s temperature and humidity. By replacing this almost 30-year-old unit, NRRI will be increasing the overall air quality and saving $2,290.07 per year through improved unit efficiency, decreased water consumption, and lower sewage requirements. In addition, nearly 22,000 kWh’s of electricity will be saved each year which is equivalent to reducing 15 metric tons of carbon dioxide or taking 3 passenger vehicles of the road.

Lighting and VFD retrofits

Many projects have included installing LED fixtures, one project consisting of the installation of 300 LED fixtures and the other consisting of 50 LED fixtures plus 7 variable frequency drives (VFD). Some LEDs have been installed in campus housing buildings and VFD and LED lighting upgrades took place in Rec Sports Gyms. VFD retrofits are scattered across campus and allow for more efficient control of motor speeds based on system requirements. With the energy savings from increased efficiency and rebates from Minnesota Power, both projects have incredible payback periods of less than 3 years.

Kathryn A. Martin Library LED Retrofit (Phase II)

LED's in libraryLED technology has allowed UMD to reduce carbon emissions due to the energy consumption of lamps in many areas of campus.  More recently, the Green Revolving Fund has allowed 300 lamp fixtures to be upgraded to LEDs.  Although this is still a work in progress, the results are already visible throughout the first two floors and in the main concourse.  LED technology greatly reduces energy consumption and reduces long-term maintenance costs. The new light sources also provide a higher-quality light that will improve aesthetics and may increase productivity.

Due to the high demand for lighting in a library setting, this project has an extremely fast payback time. Costs to illuminate the library are estimated to be $5,600 less per year with the new LEDs. This means that the upgrades will pay for themselves in less than three years and continue to save money even after that.

Campus Heating Plant – Boiler Fan Control Upgrades

Variable frequency drives (VFDs) were installed to control the current boiler fan motors which handle the heating of the majority of campus. As the demands of the boiler adjust to the outside weather and other loading conditions, the amount of heat required changes. These fluctuations in loading directly affect the amount of air needed by the system, and the installation of this system increased the efficiency on both the electric and natural gas sides of the energy use.

This project has reduced plant gas and electrical consumption for the boiler system. The electrical system has a reduced usage of 135,523 kWhs per year, while the natural gas consumption was reduced by 30,664 therms per year. This reduced the overall carbon footprint of the campus as well as reduces the consumption of natural resources.

The electric cost savings are approximately $5,000 per year coupled with a rebate from Minnesota Power at $5,200, creating a payback time period of just under 6 years. This payback does not include the natural gas savings which account for an additional $20,000 in cost savings. These additional cost savings and rebates equate to an actual payback period of just 14 months.

Refrigerator Exchange Program

From 2011 until 2016, the Green Revolving Fund helped replace 36 old refrigerators, freezers, and chillers on campus. Through energy efficiency and consolidation, the replacement of equipment is estimated to save UMD over 38,000 kilowatt-hours worth of electricity annually, and over $2,700 each year in electricity costs.  More importantly, the savings from upgrading to more efficient equipment saves 29 metric tons of greenhouse gas emissions each year!

VenDen Renovation

Students have long used the VenDen, located on the lower level of Bohannon Hall, as a space to relax between classes, do homework, visit with others, and have a quick bite to eat. Unfortunately, the facility had been ignored for many years and was outdated with a look and feel from the 1970’s. Partial funding from the Green Revolving Fund helped the VenDen update ventilation technology, energy efficient lighting, and new vending machines.

Chem 200 Update

As the largest lecture hall on campus, Chem 200 requires a significant amount of energy to run properly. The air handling unit for this room used to run 24/7 but by installing direct digital controls (DDC) we are now able to better control and schedule occupied and unoccupied times. By reducing the time that the unit is running we are reducing energy usage, wear on the mechanical equipment, and the amount of steam and chilled water for regulating temperature.

Wind Turbine Installation

A multidisciplinary group of faculty, staff, and students from sustainability, biology, geography, and engineering departments worked together on a project to install a small 5-kilowatt wind turbine in the center of the SAP Farm along Riley Road. The high variability in wind speeds at the farm proved to be a challenge for the turbine. In the Spring of 2016, the original horizontal-axis turbine was brought down and replaced with a vertical-axis turbine that would better handle these gusty conditions. This innovative project has provided UMD and the Duluth community with a new research and learning opportunity for students, staff, faculty and community members.

REC Sports Gyms

gym lighting

During March 2017, two of the REC sports gyms got a facelift. Thirty-two inefficient light fixtures were replaced with new energy efficient LEDs. Before the fixtures used 400 watt bulbs for a total of 12,800 watts, now they use 150 watt bulbs reducing the total electricity usage to 4,800 watts. That’s electricity savings of 63%!

In addition to using more efficient bulbs, dimming and occupancy sensors were installed to save even more energy. In one gym, the lights will dim to 40% after 10 minutes and turn off completely after another three minutes. In the other gym, the lights dim to 40% after 10 minutes and stay dimmed. Facilities Management is doing a trial to determine which system people seem to like better.
