Week 4 & 5 Update

Posted by Austin Jung on February 28, 2019

Good afternoon all,

There was no week 4 update because of some time conflicts which lead to the cancelation of the meeting. This week proceeded normally and we recapped what happened for week 4 and continued progress forward on determining what data is needed for the chiller plants to determine their efficiencies and line losses. To keep everyone up to date last week I was able to email three different combined heat and power plants, they were in London, Helsinki, and Copenhagen. They either did not get back to me or told me to review what is on their site because no further information can be released. After reviewing all of their sites, I was still not able to find more information on water consumption of CHPs or how it is monitored. I also emailed Ashlynn Stillwell who is a professor here at UIUC and has done research on water consumption. She was able to give me some helpful sources to find industry standards on energy, fuel, and water consumption of all power plants.

In this week’s meeting we reviewed the excel spread sheet I created to determine what data would need to be collected for our analysis of the chiller plants. We came to the conclusion that the water makeup (potable water) for each chiller plant, total Water Chilled at each chiller plant, energy used at each chiller plant, and total chilled water metered from buildings in the loop. With this data the cooling and energy efficiencies can be determined along with the line losses.

For next week’s meeting we will be trying to figure out who to contact to determine which buildings have been retro fitted with the new low flow water fixtures and which have not yet. I will also be continuing my research on CHPs and reading into the master utilities plan. After reviewing the excel sheet I am going to make some edits to prepare it for when get our data. Thanks for keeping up and I will be back next week.
