All:

Staying consistent with the guidelines issued by the CDC and University of Illinois effective Friday, March 20, 2020 at 3PM the sort line will be closed at the University of Illinois Waste Transfer Station until further notice Enumerated below are the changes effective 3/20/2020:

• DSC staff has been notified and will not be sending their staff to the waste transfer station starting Monday, March 23, 2020.
• No waste will be sent to the sort line. All collected mixed waste will be sent directly to the landfill.
• Pre-sorted materials such as a paper and cardboard will be continued to be collected and processed on the floor as normal.
• Pre-sorted materials such as bottles and cans will be stored in a roll-off container to be processed at a later time.
• All staff that will continue to work during this time at the WTS must adhere to the guidelines outlined by the Centers for Disease Control and Prevention

Please note that there will be no change in waste and recycling collection schedules. Facilities and Services will continue to collect source separated trash and recycling from campus dumpster there will be no change in collection service. As there will be no material going to the sort line we do not anticipate an increase in material as most of campus is currently working remotely. Facilities and Services will be working with Area to monitor generation and evaluate if additional hauling service would be needed.

We thank you for your support and understanding during these unprecedented times. As always, if you have any questions or concerns please feel free to reach me or my team directly.

Good morning Morgan,

I have gathered the numbers that correspond to an acre of solar cover. 

The estimate is that an acre of solar canopy could generate 760,536 kWh annually (this estimate takes into account the weather patterns of our location and possible shading/system inefficiencies).  

I remember you saying that right now the University pays $0.05 per kWh.  Our solar farms are charged $0.045 per kWh that they generate.  This means that $0.005 is saved for every kWh generated.  That can be used to estimate that an acre of solar canopy would save roughly $3,800 per year.  

I thought that I would also include the National Renewable Energy Laboratory’s estimate for what a solar retailer would charge per kWh of electricity in our area: $0.036.  This would mean that $0.014 could be saved per kWh on a solar canopy system, or roughly $10,650 per acre.  

Let me know what else I can find,

Ryan Day

I am on the team that did the Retrocommissioning project in 2018 and I would be happy to share some of our knowledge from that process.  Below is the link to a presentation of that project that we took to a Big Ten energy conference.   Some of our main takeaways are that the combination of chilled beams, dual HX wheels, coil sizing, occupancy ventilation, and thoughtful building pressurization have led to one of the most efficient buildings on campus.  Also, the heat pumps work well to heat/cool with electricity, but would be optimal if there were more of a reheat load, or a hot water loop to send reject heat to a neighboring building in summer, which campus is looking into in certain locations.
