  3. iWG Meeting Minutes from 4-27-21

    The iWG met on April 27, 2021, and discussed the iCAP Team recommendations: ZW002 Join NERC Government Recycling Demand Champions, ZW003 GreenerOffice Delivery Service Enrollment, ZW004 Reusable Dining Containers Program, LW002 Vet Med Parking Re-Design, and LW003 Certified Green Building Certification. See meeting minutes attached.

  4. LW003 Certified Greener Building Certification - Submitted

    The Land and Water iCAP team submitted the following Certified Greener Building Certification recommendation on 4/2/21:

    "The Land and Water iCAP Team recommends the creation of a Certified Greener Building Program to add to the portfolio of Greener Campus Programs under iSEE. The existing Greener Campus Programs target nearly every facet of campus life from University employees to student experiences. A Greener Building Certification would provide an opportunity for collaboration between building liaisons and the people and groups that utilize campus buildings. A set of requirements and voluntary actions must be developed to achieve the certification. Based on the success of the existing Certified Greener Campus programs, students, faculty, and staff alike are very likely to take advantage of the certification opportunity and embed these actions as part of building operations. These actions will also promote life-long sustainable habits. A Greener Building Certification would establish a sustainability standard and increase our culture of sustainability on campus."

  5. LW002 Vet Med Parking Lot Re-Design - Submitted

    The Land and Water iCAP team submitted the following LW002 Vet Med Parking Lot Re-Design recommendation on 4/2/21:

    "This recommendation calls for a redesign of the Vet-Med parking lot F27 to reduce runoff and prevent flooding of the Dairy Farm. Project design recommendations would include adding stormwater infrastructure such as bioswales and raingardens within the redesigned parking lot, as well as to the west of the parking lot where much of the runoff from the asphalt currently flows. A student project, which placed first in the Central States Water Environmental Association Student Design Competition: Environmental Category addresses this issue, but the team recommends hiring a Professional Services Consultant team, consisting of a professional engineer and landscape architect for the design. It is possible that the firm may be willing to donate the design, which would reduce the cost."

  7. LW001 Data Repository - Submitted

    The Land and Water SWATeam made the following recommendation on 4/2/2020: 

    The Land & Water SWATeam recommends that a single data repository and online dashboard should be established to ingest, archive, and disseminate data from various sustainability related monitoring on and around campus. This could potentially be a dashboard included on the iCAP Portal.

    Currently, there is a need to keep permanent records of original data and measurements from a variety of sensors and applications and in a variety of formats.  The university should be able to provide reliable, secure online access to sustainability-related monitoring data, to manage all monitoring network locations, to integrate data acquisition systems and external databases, and automate continuous data importing. Data such as water quality, soil moisture, green roof monitoring, nitrogen content will be tracked. Data can be input as public or private (such as data from research papers before publication) and entered manually or pulled from other platforms and software. The goal is to be able to provide online tools to visualize, analyze, and download data.

    The SWATeam has identified two potential options to develop this system, such as the College of ACES Soil Diagnostics proprietary software. Additionally, personnel from the Ven Te Chow Hydrosystems Lab in the Department of Civil & Environmental Engineering have developed a natural-resources data-management system that is able to assimilate and store data from a wide variety of sensors and provide online access to user-selected data streams (described in Explanation and Background section).

    The Land & Water SWATeam recommends that iSEE provide support to make this system the repository and dashboard for all sustainability-related monitoring across campus.  This would provide a single portal that would enable students, faculty, University staff and administration, and the public to access these monitoring data.

    Attached is the SWATeam recommendation LW001 Data Repository with comments from Land and Water SWATeam.

  10. SWATeam Welcome Message

    Dear SWATeam members,  We are so happy to welcome you to the FY20 SWATeams, including Energy, Land and Water, Zero Waste, Transportation, Education, and the new Resilience Working Advisory Team (RWAT).  SWATeams are an important part of our overall Illinois Climate Action Plan (iCAP) efforts, and we truly appreciate your assistance and support

     

    In 2014, iSEE worked with the Office of the Chancellor to develop the formal sustainability procedures to support the Carbon Commitment.  These procedures established the SWATeams, the iCAP Working Group (iWG), and the Sustainability Council.  In 2018 Chancellor Jones and the Mayors of Urbana and Champaign signed a Resilience Proclamation, so RWAT is the newest part of our SWATeam process.  We are currently working on an update to the iCAP procedures document. We’re also updating the 2015 iCAP plan to the new 2020 iCAP, and FY20 SWATeams will contribute to such an important milestone of iCAP!

     

    For both returning and new SWATeam members, here are a few things to expect in the coming weeks:

    • iSEE Director Evan DeLucia will be sending a formal charge letter for each team.
    • iSEE Sustainable Programs Coordinator Meredith Moore is training the new SWATeam clerks and graduate assistant, Regina Cassidy.  Then the SWATeam clerks will contact you to schedule three full team meetings this semester, one in September, October, and November.
    • The SWATeam pages on iSEE have been updated, and we will be updating the iCAP Portal pages.
    • We will send you a schedule for the 2020 iCAP development, with specific timelines for the SWATeams to draft specific, measurable objectives for the 2020 iCAP.
    • You will receive an invitation to the SWATeam kick-off event, hosted by iSEE in September.

    As mentioned above, this year will be highly focused on drafting the 2020 Illinois Climate Action Plan iCAP.  Each of the SWATeams will be asked to recommend specific, measurable objectives for the 2020 iCAP.  To help facilitate this effort, the two of us, as co-chairs of iWG, will both be attending each full SWATeam meeting in September, October, and November.  The actual iCAP chapters will be written by members of the iWG and iSEE staff, based on the input received from SWATeams and campus, for review by the iWG.  In Spring 2020, there will be campus and community review of the draft chapters, and the SWATeams will be included as key stakeholders in that review process. Ultimately, the 2020 iCAP with a chapter for each SWATeam, and additional related chapters will be formally submitted to the Sustainability Council for campus approval.

     

    The University is committed to being carbon neutral as soon as possible, and no later than 2050, and to bolstering our community’s resilience to the impacts of climate change. SWATeams play a key role to achieve those goals. We thank you for your willingness to assist in the efforts that will make us a model of sustainability for the nation. Thank you for your time, your enthusiasm and your continuous efforts!

     

    Sincerely,

  11. Water Use and Cycles of Concentration (COC) in a cooling tower

    Below is information provided by Jeremy Overmann, B.S. Ch. E., Water Treatment Specialist, on the water use and cycles of concentration (COC) in a cooling tower, as requested after a Land and Water SWAT meeting. 

    "

    Water SWAT members,

     

    Here is some more information regarding the cooling tower discussion at today’s meeting.

     

    This first graph shows how much water a typical 100 ton Cooling Tower uses per hour, and how this changes when the tower is operated at various Cycles of Concentration (COC)

    NOTE:  a 1 ton cooling tower can remove 15,000 BTU/hr of heat.

     

    2Q==

     

    Most standard chemically treated Cooling Towers use unsoftened water and operate between 4 – 6 COC, depending on the source water quality (also called Make-Up water) and the efficacy of the chemical treatment program.

    As COC increases, the potential for formation of calcium scale (and possibly other types of scale) increases.  Scale deposits reduce the energy efficiency of the chiller and the cooling tower, and result in the need for labor intensive cleaning to remove the scale.

     

     

    The following table shows the relationship between volume of Cooling Tower blowdown (bleed), blowdown rate (% bleed), COC, and total water usage.

    Cycles of Concentration is controlled by choosing the rate of blowdown.  This is done by controlling the blowdown (bleed) valve at the bottom of the tower.

    In a “Zero” blowdown cooling tower, softened water is used, and cycles of concentration ranges from 20 – 100 or higher.  To achieve proper water chemistry to provide corrosion protection, usually need to operate at > 20 COC. 

    During the Champaign Regional Office Building study, the highest COC achieved was 51.  The blowdown valve is turned off, however some water is lost from leaks in the tower, and from droplets of water that escape with the air that is drawn through the tower.
