Jeff Holt met with Morgan White today to discuss the rooftop solar project on the Speech and Hearing Sciences Building. We discussed solar installer certifications (NABCEP), in-house construction options, and coordination with the Capital project being managed by Kevin Price. We also discussed the options for requesting additional funding from the Student Sustainability Committee, to be able to install more of the solar.

- Associated Project(s):
Work Request 253325 converted to Work Order 10519389

Phase: 001 DESIGN SERVICES
F&S staff met to discuss the Speech and Hearing Sciences Building Rooftop Solar PVs project. Managing Engineer Kristine Chalifoux and Electrical Engineer Brian Finet will take the lead on the design. The design will use a ballast mounting system, real time energy meters, and an online solar dashboard.
Brian Finet shared a preliminary sketched layout for the Speech and Hearing Rooftop Solar PV, in a short meeting with Morgan Johnston and Robert Halverson. During the spring funding meeting of the Student Sustainability Committee, they questioned if it was possible to do a scalable design for this building, so more than the originally funded 11kW could be installed in the future. The answer is yes, this is highly scalable.
Morgan Johnston, Robert Halverson, and Brian Finet met to discuss the design needs of the Speech and Hearing Rooftop Solar PVs project (on building #209). Key points discussed are:
Per the building occupants, this project needs to be installed at the same time as the Capital Project in that building, currently scheduled for summer 2017. Therefore, the bulk of the design needs to be completed by December 2016, and the installation methodology should be clarified in September or October, 2016.
The project must be metered, in order to track the solar energy generation. There are several metering options and considerations to be addressed. The meter needs to track real-time energy generation from the array, but this project does not currently include setting up a dashboard website specifically for this array.
Discussion about the pros and cons of various mounting methods were discussed. Additional potential for rooftop leaks are the primary concern for building occupants and maintenance contacts. The most manageable installation style is to connect the solar panels to an existing load bearing column for the building. Ballast style installations, while not creating an immediate rooftop penetration point, are very likely to wear on the roof and create non-point source leaks which are hard to find and eliminate. Additionally, with a ballasted mounting system the snow load is difficult to calculate due to the unpredictable effect of snow drifts.
One of the strategies outlined in the Illinois Climate Action Plan is a significant increase in the amount of solar energy on campus, which would include rooftop panels as part of the plan. Toward that end, SSC is funding an 11-kilowatt array on the roof of the Speech and Hearing Building. This specific location was selected due to its viability, visibility, and location near the heart of campus.Attached Files:
