  1. Week 10 Update

    Associated Project(s): 

    Good Afternoon All,

    This week’s meeting was productive and we were able to set up the excel spreadsheets needed to record data on the chiller plants, Abbott, and potable water. Over the past week I researched and created a checklist and table for conducting a water audit. The checklist will be shared here after some final corrections are made to it. I was able to determine what was needed and where stamped flow volumes are marked on each fixture. If there is no stamp on faucets there is a simple tool called a flow rate bag that will be purchased so auditors can determine the flow manually. As for urinals and lavatories the model and serial number will be recorded to search the model manually and figure out the flow rate. There is no hand tool to determine these flow rates.

    The spreadsheets will be given to Mike Marquissee so his team can collect the data we need faster. Once the data is collected some analysis of it will be done to help us determine efficiencies and water consumption of the different facilities. Also it will help us figure out if we have line losses in our systems.

    The next steps to be done this week is to get these excel spreadsheets to Mike and give him some time to gather all of the data we need. Analyze the raw data and compare the values to industry and national standards. This will allow us to figure out where we stand in our water consumption. Finish editing the water audit checklist and add snap shots of where the stamps can be located so it will be easier for auditors to know where to look. The water audit program we are creating right now will mainly be used for bathrooms and kitchens in university buildings. Research laboratories and student laboratories will be done by another team and program in the works.

    Thank You,

  2. 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

  3. Uni High steam conservation project

    Associated Project(s): 

    Dave Hardin submitted a small project to replace about 35 obsolete thermostats and about 55 steam valves. There are several valves that are leaking through and heating the spaces, resulting in increased utility usage, as well as occupant discomfort. While we are doing this work, we will install a main isolation valve on the steam entrance line that is control by outside air temperature. Steam distribution goes around campus and turns the steam on/off twice a year for cooling and heating season, and with our lovely Illinois weather we could have significant temperatures swings that result in simultaneous heating and cooling situations. This isolation valve will eliminate those issues as well as provide a more comfortable building for the occupants while transitioning through season changes.
