The proposed project for a solar array at the Speech and Hearing building was deemed canceled due to the design study which found the roof unable to hold the solar array, as well as an informal shade assessment which found that the panels would not get all day sun due to the existing buildings.

Please see below a conversation between Morgan White, Jen Frattergio, and Paul Foote regarding this project:

Hello Jen,

I hope you are having an enjoyable Friday!

I have a quick question, Marth, Aman and I did a quick assessment of the Speech and Hearing bldg. for rooftop solar array and found it to be a poor source for solar insolation due to the Psychology bldg.. shadowing over it for the morning hours and

then there are some trees that block summer sun to the north and west as well.

We are tasked with submitting an IL Green Fund (SSC) application for this project and I am wondering if there is a reason this location was chosen and/or can we select another location that may produce higher outputs from the sola array?

Here is the charge language: Develop and submit an application to IL Green Fund (SSC) for rooftop Solar on Speech and Hearing Sciences Building in collaboration with stakeholders.

Jen forwarded the inquiry to Morgan White and Stacey DeLorenzo:

Hi Morgan and Stacey,

See below for a question from Paul and the Energy Team.

Morgan, you had suggested the team apply for funding from the IL Green Fund (SSC) for rooftop solar on the Speech and Hearing Sciences Building. What was the reasoning behind this recommendation? Is a tool used or an analysis done to identify suitable buildings for installations?

Hi Jen,

Just to close the loop on this old question from 1.5 years ago…  There was an analysis of large roofs that could potentially be retrofitted with solar.  Many of the large roofs are made with gypsum board which is not strong enough for panels, and the remainder would require a structural analysis.  Someone said the Speech and Hearing Sciences Building was retrofitted with a different lower-weight type of insulation which should make it viable to handle the weight of solar panels.  We did an in-house assessment with F&S Design Services, and it was found that the roof could hold the weight of the panels.  Then the Student Sustainability Committee funded a full design, which was completed and is on the iCAP Portal / in F&S records.  The iCAP Energy Team pointed out that the new high-rises around the facility block a lot of the sunlight, so the project was essentially cancelled.  I think it would still be helpful to do a shade study for the building, and potentially it could have a green roof on it.  It is very visible from the Hub (one of the highrises nearby), so it could be a visible sign of our climate action.
