  5. SSC funds occupancy sensors

    Bevier Hall currently has a number of spaces served by obsolete thermostat controls. While efforts to improve scheduling for heating and cooling have made improvements to energy consumption, the installation of occupancy sensors would improve the efficiency of the HVAC system, reducing energy use without sacrificing user comfort. This funding provides resources to install new occupancy sensors in 25 lab, classroom, and office spaces in Bevier Hall. When completed, the heating and cooling system will be able to work more efficiently, eliminating the need to constantly provide conditioning for unoccupied spaces. Individual spaces will have better temperature control, therefore improving occupant comfort and increasing productivity. This is a Student Sustainability Committee supported project.

  6. Revolving Loan Fund projects approved

    The Revolving Loan Fund selection committee has approved funding for all the viable RLF projects.  See attached image for list.

  7. FLB Green Lighting Funding Agreement

    Hallways in the Foreign Language Building, especially on the upper floors, may go long periods with no traffic. However, the overhead lighting is always on, which is extremely energy inefficient. This project aims to replace some of the overhead lighting with more energy efficient options and install occupancy sensors to automatically dim the lights when people are not present.

  9. 2009 Classroom Occupancy Sensor Installation

    Associated Project(s): 

    In 2009, the Student Sustainability Committee awarded $50,000 to Facilities & Services for installation of occupancy sensors to control lights in ten campus buildings: Animal Sciences Laboratory, Architecture Building, Bevier Hall, Chemistry Annex, Huff Hall, Materials Science and Engineering Building, Mumford Hall, Music Building, Noyes Laboratory and Transportation Building. The funds were used to install a total of 230 occupancy sensors in 223 rooms in these ten buildings.

  10. 2008 Classroom Occupancy Sensor Installation

    Associated Project(s): 

    In 2008, the Student Sustainability Committee awarded $20,000 to Facilities & Services for installation of occupancy sensors to control lights in three campus buildings: Loomis Laboratory, Foreign Languages Building, and Armory. Later, the budget was increased to $50,000 and the scope expanded to include seven additional buildings: Davenport Hall, Everitt Electrical Building, English Building, Henry Administration Building, Psychology Laboratory, Mechanical Engineering Building, and Wohlers Hall. The funds were used to install a total of 332 occupancy sensors in 272 rooms in these ten buildings.

  11. Racquetball Court Energy Reduction Project

    Associated Project(s): 

    Twelve racquetball and three squash courts at the Activities and Recreation Center (ARC) were retrofit with 193 fluorescent and 96 mercury vapor light fixtures. The project was funded by the Student Sustainability Committee through an interest-free loan of $75,000.

    Once the lighting retrofits were completed, occupancy sensors were installed in all 15 courts.

    The overall cost of the project ended up at $61,203.69 -- $13,796.31 less than the original quote. Campus Recreation requested that the remaining balance stay with the division and be used to further fund energy reduction projects within their facilities.

    The total average reduction in power consumption is 129,226 kWh. This is a 75.7 percent decrease in consumption, which translates to an annual savings of $9,020. The simple payback for this project is 6.78 years.

  12. RLF Occupancy Sensors FY12

    Associated Project(s): 

    Ten buildings on the University of Illinois at Urbana-Champaign campus were selected to receive RLF funding for occupancy sensors in FY12. In order from top priority to lowest priority, the buildings that received funding are Gregory Hall, the Foreign Languages Building, the Agriculture Engineering Sciences Building, Newmark Laboratory, the Rehabilitation Education Center, the Education Building, the Law Building, the Water Survey Buildings, Noyes Laboratory, and Freer Hall. The University will now proceed to implementation of occupancy sensors in all of the above buildings.

    Gregory Hall, the Foreign Languages Building, Newmark Laboratory, the Rehabilitation Education Center, Noyes Laboratory, and Freer Hall have also been selected to receive HVAC occupancy sensors.

  13. Campuswide Occupancy Sensors

    In 2008, $50,000 was awarded to Facilities and Services to install occupancy sensors in 272 rooms across 10 highly-visible campus buildings. Where in use, the automatic lighting controls reduce energy usage by 30% (total savings of $11,900/year plus inflation) and greenhouse gas emissions (by 88,000 lbs CO2, 323 lbs of NOx, and 1,079 lbs SOx per year). The sensors are a daily reminder to students, faculty, staff, and visitors of the University of Illinois’ commitment to sustainability.

  14. IUB Retrocommissioning and Occupancy Sensors Loan

    Program Background:

    The Student Sustainability Committee (SSC) is tasked with the allocation of the proceeds of two student environmental fees – the Clean Energy Technology Fee and the Sustainable Campus Environment Fee, to improve the sustainability of our campus. The committee has established a program to make funds available for efficiency projects that will be later returned for reinvestment in future projects.

    Committee funds will be made available to the Office of Sustainability which will carry out an inter-departmental transfer to the Receiving campus unit. The Receiving unit agrees to return the transfer to the Office of Sustainability, in installments, as described on the next page, for reuse by the SSC.

    Project Description:            

    The Illini Union seeks funding to retro-commission the Illini Union Bookstore building, and to install Occupancy Sensors in the Illini Union building. The Illini Union Bookstore building contains both academic and auxiliary units, and the SSC loan will allow for complete retro-commissioning of the building. Retro-commissioning is expected to cost $113,000; the RCx process identifies defective components within the HVAC systems, reconfiguring and controlling them to function more efficiently, decreasing wear and tear and extending their service life by 20 years (as part of a regular preventative maintenance program), as well as reducing building energy consumption.

    The SSC loan will also provide $67,000 to install lighting occupancy sensors in the Illini Union, in food service preparation areas, restrooms, office areas and meeting rooms, which will reduce energy and lighting use.


    The Student Sustainability Committee is in favor of the Office of Sustainability transferring an amount of $180,000 to the Illini Union completion of this work. These funds are to be drawn from the Sustainable Campus Environment Fee account managed by the SSC, as needed to complete the project. All funds requested from the SSC must be expended before 30th September 2010, else the unit must apply for an extension.

    The Illini Union agrees to return the funds provided by carrying out annual transfers to the Office of Sustainability due on the 15th of August of each year in the following manner:

    $20,000 – Due 15th August 2011

    $40,000 – Due 15th August 2012

    $40,000 – Due 15th August 2013

    $40,000 – Due 15th August 2014

    $40,000 – Due 15th August 2015

    The Office of Sustainability will direct them back to the Committee’s account. The Illini Union will provide a close-out report about the project after installation. The Illini Union will also appropriately publicize the Committee’s support of these projects.

    All funds provided by this transfer will be used in a manner consistent with University of Illinois policies and procedures.

  15. Occupancy Sensors Funding Agreement

    This proposal looks to install occupancy sensors in classrooms, hallways, restrooms, lounges, and other public areas in twenty heavily used campus buildings, chosen according to the number of student contact hours. This project will reduce energy usage by 30% in affected areas, saving the campus approximately $18,000 per year in energy costs (based on a $0.0689/kWh rate), and reduce emissions by nearly 440,000 lbs of CO2 equivalent. This highly visible effort is expected to increase student and community awareness of the impact of reducing lighting usage. These sensors will serve as a lasting and permanent public statement of campus commitment to responsible sustainable behavior. Thus, the Student Sustainability Committee is in favor of funding the fully requested amount of $50,000.

  16. Occupancy Sensors (Automatic Lighting Controls) Funding Agreement

    The goal of this project is to install lighting sensors in classrooms in several University instructional buildings (e.g. the Armory, the Foreign Language Building and Loomis). The sensors will switch off the lights in these areas, after 30 minutes of inactivity, which will reduce lighting consumption by ~30%. Additionally, having these retrofits take place at the same time as additional lighting upgrades will reduce overall installation costs. Given the reduction in lighting and electricity usage, the high visibility to students of the target areas and student interest in this technology, the Student Sustainability Committee is in favor of funding the full requested amount of $50,000.
