  1. Week 4 & 5 Update

    Associated Project(s): 

    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.

    Best,

    Austin Jung

  2. Week 3 Update

    Associated Project(s): 

    Good morning,

    Week 3’s meeting was a very informative and productive with the help of Mike, who is the director of budgeting and resource planning for the energy services division. Mike was able to help confirm and teach us about what is exactly happening at the chiller plants. He caught us up to date on what is being metered and where to find certain information. Together we brainstormed ideas on how we can determine a metric to measure the water consumption of each chiller plant. This included the metered water going into the cooling tower, water going into the chiller loop, and comparing that number to the total chilled water produced. Alongside this comparison the BTUs will also be monitored to see how much energy is being used to produce all of this.

    There are a couple of tasks that I will be getting done for week 4’s meeting. These include and not limited to:

    • Creating a list of resources needed to be collected to determine the efficiency of the chiller plants and how much water/energy they consume
    • Email other combine heat and power and chiller plants to see how they track or measure their water consumption
    • Email Ashlynn Stillwill to see if she knows any good places to look for national and industry averages and standards
    • Look into BIF’s grey water meter to determine how much water could be saved if grey water system was enabled

    This week was successful and looking forward to the information that will be collected in the following weeks. The attached document is some notes on UIUC cooling towers, Abbott, chiller plants, CHP plants, and our meeting.

     

    Thank you,
    Austin Jung

  3. Week 2 Update

    Associated Project(s): 

    Good morning all,

    Austin here and yesterday’s meeting with Morgan White and Sarthak Prasad went well. I reviewed articles on how power plants use freshwater and the ways to reduce their consumption. The biggest factor in water use at power plants is their cooling system. The metric for measuring this is gallon per KWh and it’s categorized by their withdrawal, consumption, and discharge. The different types of cooling systems have their own pros and cons. For example wet recirculating cooling is good because it doesn’t withdrawal a lot of water but it consumes more than the other methods. Then an example of an advanced cooling system is a hybrid system that used air and a cooling tower to combine the advantages of a cooling tower and the resourcefulness of using a dry system. The draw backs of using only air is it makes the thermal conversion efficiency go down and increases operational costs. More details can be found in the attached file.

    We proceeded to continue research on how our power plant and chiller plants operate by looking at the water and energy consumption of the billing logs. We plan on meeting with Mike next week to gain more insight on the chiller plants and their water consumption. Then we looked at the piping layouts for the Universities potable and cooling water pipelines.

    To further our research I will finish reviewing some more articles on cooling tower water consumption. Then find articles with more detail on how cogeneration plants work and what metrics are used to measure their energy and water consumption. There should be more data on this from different European studies because they have similar systems like ours at Abbott. Lastly I will familiarize myself with our systems by researching the chiller plants and Abbott information given on the Facility & Services webpage.

    Thanks,
    Austin Jung

  4. Meeting Minutes for iWG February, 2019

  5. Week 1 Update

    Associated Project(s): 

    Good evening everyone,

    My name is Austin Jung and I am a senior in chemical engineering with a minor in the iSEE Fellows Program. I will be helping Morgan White and Sarthak Prasad with the 2015 iCAP objective #5.3 water audits for my SEE Fellow’s senior capstone. After the first successful meeting, the following will be addressed through the semester:

    • Create a water audit program/process for an existing building that will be the basis for the campus wide water audit.
    • Quantify and reduce the distribution and line losses for steam by measuring the steam/condensate loss. Then compare this to the national and peer averages.
    • Develop a list of buildings that have and need to have their water fixtures upgraded.
    • Find out a metric to measure the water consumption of our power plant and water cooling plants to develop a way to record this data for further analysis.
    • Continue support to help F&S meet their water consumption goals.

    These will be the main objectives focused on during the capstone and any changes will be stated in one of the following weekly updates. I am excited to do my part and begin my investigations.

    Thanks,

    Austin Jung

     

  6. Water004 GSI Standards Parking Lots recommendation - Successful

    Executive Director of Facilities & Services, Mohammed Atalla, responded over email to Ximing Cai (iSEE Associate Director for Campus Sustainability) in support of the recommendation:

    "Facilities & Services will proceed with incorporating Green Stormwater Infrastructure in to the Facility Standards. Brent Lewis is the point person for this effort, and he will add GSI information to each of the relevant standards. This includes but is not limited to the sections on parking lots, transportation, sustainability, and stormwater.

    Thank you very much Morgan for your work to coordinate this activity with Jim and Brent."

  7. Water005 Rainworks Design Lot F4 recommendation - Successful

    Director of Parking at the University of Illinois, Marty Paulins, responded over email to Ximing Cai (iSEE Associate Director for Campus Sustainability) in support of the recommendation:

    "Parking supports the recommendation to do a feasibility study for Lot F4, incorporating the green infrastructure from the conceptualization completed by the students in the award winning rainworks challenge."
