Weekly Update
Associated Project(s):All, the shop was closed for Spring Break, so going back two weeks to 3/13 – 3/17: Visitors totaled 60. We grossed $839.20. We sold 4 memberships for $120; one refurbished bike for $180; and one build-a-bike for $134.
This week I will be prepping for summer staff, building bikes, organizing/cleaning, getting in touch with the new supply representative, and attempting to streamline the reporting of stolen bikes.
Additionally, the Bike Project is hosting a bike light giveaway at Douglass Park in Champaign on Sunday (April 2nd; 2 - 5pm) that I will promote this week.

Attached Files:Water Use and Cycles of Concentration (COC) in a cooling tower
Associated Project(s):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.
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.

Associated Project(s):Updates on BIF Greywater Meter application. Discussion on Cooling Tower COC and "Zero" blowdown systems.
Attached Files:Weekly Update
Associated Project(s):All, Happy Monday! Last week was a steady busy one. We routinely had peaks of busyness and fallow valleys. We had 97 visitors through the doors, including staff. We grossed $951.50. We sold two bikes for $335; one build-a-bike for $61; and 4 memberships for $120.
Overall, last week I was met with a little more enthusiasm for the space than I regularly receive upon explaining the cost structure and mission of the CBC to new visitors. That was nice. Our for-sale bike count after last week sits at 14 for-sale bikes. I keep trying to grow that number up into the 20s but people keep buying them. That’s not a bad thing, I suppose.
Additionally, the two Departmental Share bikes need parts that are on-order so that project will be delayed, unfortunately.
Our numbers for B-a-Bs last year was quite low and as such I will begin photographing—with permission—all those who complete build-a-bikes and posting them on social media, which will serve two important functions: advertising for CBC and its most education-intensive program; and having a picture of owner and bicycle in the event of a stolen or lost bike.
This week I am going to cull a few more unbuiildable bikes from the pile and concentrate heavily on ramping up the for-sale numbers since this week of cold, snowy weather should keep the shoppers at bay. I will additionally focus on drop-bar bicycles, since I’ve noticed people requesting and looking for those more than the about-town cruisers and flat-bar bikes we have for sale, irrespective of how well-suited they are to campus riding.Sincerely,
Jake Benjamin
Campus Bike Center Manager

Attached Files:iWG Meeting Notes from Jan. 27, 2017
Associated Project(s):The iCAP Working Group met and discussed the following agenda items. Meeting notes are attached.
1. Brief iCAP Portal overview by Morgan
2. Discuss any updates to Water002, Cooling Tower Increase COC
3. Discuss Trans008, Bike Parking in Ramps
4. Discuss updates to Econs004, Green Labs Coordinator
5. Consider issues with recommendation process and view recommendation trackerAttached Files:Sustainability staff discussed the outreach programs on the portal
Associated Project(s):Morgan Johnston, Catherine Yee, and Chenxi Jiang met today to discuss the outreach information listed on the iCAP Portal. Catherine described the Student Sustainability Leadership Council (SSLC) and the Certified Green Office Program (CGOP). We also discussed the Earth Week efforts and the overall purpose of the SSLC as a networking opportunity for students in sustainability groups.
Conservation Budget Recommendation (ECONS003) - Transmittal to the Council
Associated Project(s):ECONS003 Conservation Budget Recommendation was transmitted to the Office of the Provost on March 6, 2017. The Council discussed the recommendation at this meeting.
Weekly Update
Associated Project(s):All, last week we had 114 visitors. We grossed $997.25. We sold two bikes for $210 and six memberships for $180. The new hires are coming along, with only minor hiccups here and there.
Last week Lily and I assisted with the University High School Agora Days class that a Bike Project member was leading. For Four days last week we went over various bike repair basics, focusing on tires/tubes, minor brake adjustments, chains, and a how-to on bike fitting. The kids were genuinely interested and engaged, and no one minded getting a little dirty. The only downside was the one-hour limit on each day’s class.
Lily and I also met to discuss the implementation of some bike classes for which she so adeptly secured funding.This week I will get a job posting up for more student workers, as one new hire is MIA and a few others are graduating. I will continue to work on the departmental bike share bikes for F&S as well as bikes for sale here, as our stock isn’t quite as robust as I would like pre-spring rush.
Sincerely,
- Jake Benjamin
