Search tips:

  • This form will search for words in the title OR the description. If you would like to search for the same term(s) across both the title and description, enter the same search term(s) in both fields.
  • This form will search for any of the words you enter in a field, not the exact phrase you enter. If you would like to search for an exact phrase, put double quotes (") around the phrase. For example, if you search for Bike Path you will get results containing either the word Bike OR the word Path, but if you search for "Bike Path" you will get results containing the exact phrase Bike Path.

  8. Join your neighbors getting solar PVs!

    Associated Project(s): 
    Solar Urbana-Champaign

    Champaign and Piatt County home and business owners installing solar energy have triggered the second 1% discount in the Solar Urbana-Champaign program! The program makes it faster, easier, and more affordable to go solar by leveraging the power of volume purchasing, and a community-education campaign.

  10. Capacity of distribution lines

    Associated Project(s): 
    Solar Farm 2.0

    U19005: Electrical-Medium Voltage Power Distribution Study Updates - should start in mid-September - to evaluate capacity of power distribution line connected to proposed solar farm 2.0 site.

  12. Feasibility study to be done

    Associated Project(s): 
    Geothermal at WPP

    Due to the complexity of this project, F&S recommended conducting a feasibility study before installation.  It is estiamted to cost approximately $10K and take about one month to complete.

  13. EUI at Fruit Farm Admin Building

    Energy Conservation Efforts

    Please see the attached Excel file for some Energy Use Intensity (MMBTU/GSF) and (kBTU/GSF) calculations for the Fruit Farm Admin Building.  I have also attached an Energy Star Portfolio Manager Technical Reference which gives numbers for average U.S. Energy Use Intensity by Property Type.  These numbers are given in kBTU/GSF for comparison.

     

    The good news is that the numbers have been decreasing from 2011 through 2017.  Since 2018 is not over yet it would not be fair to count that number, but from 2011 through 2017 the energy use intensity appears to have decreased to about half of its starting value!  The numbers range from about 299 MMBTU/GSF to about 153 MMBTU/GSF (about 45 kBTU/GSF to about 23 kBTU/GSF). 

     

    If you look in the Energy Star Portfolio Manager document, the UIUC Fruit Farm is on par with a small retail office (at the higher EUI levels from 2011) to a warehouse or other unoccupied space (at the lower EUI levels from more recent data).  This may be an indication of the level of activity of the facility, or it may just reflect the fact that you are getting a lot of geothermal energy (three to four units of geothermal energy for every one unit of electricity).  If you look in the table you will see that a laboratory is listed as 78.8 kBTU/GSF, which is about 3.5 times the 2017 calculated value of 23 kBTU/GSF for the Fruit Farm.

     

    Please note that the numbers I am comparing the Fruit Farm to are the site energy numbers in the Energy Star Portfolio Manager document, which reflect the amount of energy you are using at the site (meter readings).  Source energy numbers are higher and include losses due to energy conversion and distribution from where the energy was originally generated (likely a coal or natural gas plant in Illinois).

  14. Capacity of Solar PVs for shed roof

    Associated Project(s): 
    Solar PVs at Idea Garden

    The solar PV design for the rooftop of the Idea Garden shed is 12 panels with 340 Watts each, which is a total of 4.08 kWdc. The construction estimate is in progress at F&S, then an interconnect agreement will be needed from Ameren.

    Associated Project(s): 
    Solar Urbana-Champaign

    The City of Urbana has partnered with the Midwest Renewable Energy Association (MREA) and the Grow Solar Partnership to coordinate a second solar group buy in Champaign County, building on the success of Solar Urbana-Champaign, which took place from December 2015 through June of 2016. The advantage of a group buy is the power of volume purchasing, which can significantly reduce the up-front costs of installing solar on your home or business. You do not need to be a City of Urbana resident to participate – the group buy is open to all Champaign County residents and business owners.

  18. capacity question for rooftop solar

    Associated Project(s): 
    Solar PVs at Idea Garden

    The annual usage of electricity at the Idea Garden shed is much lower than the proposed solar array will provide.  Because this building is currently powered by Ameren and not connected to the campus electrical grid, there will be a loss of any kilowatt-hours not used during the course of one year.

    Associated Project(s): 
    Solar PVs at Idea Garden

    The Master Gardeners are interested in adding rooftop solar PVs to the garden shed to the east of the Idea Garden in the Arboretum. The Idea Garden is a community garden planned, managed and maintained by the Champaign County Master Gardener volunteers.

    The accompanying map shows the layout of the garden, The solar panels would be installed at shed (A) and provide power to building. The power grid would be extended to the garden to power light fixtures and outlets at sites B1-B4, C and D. Remodeling of the Idea Garden to provide access for people with disabilities is scheduled to begin in 2016, so this would be an opportune time to install underground cables. A small parking lot is also to be built at D. Funding for the proposed installation is not available from the grant supporting the remodel.
