The green revolution looks to be a passing fad with students, but the univeristies are still at it.
Harvard has “green lab” programs at both the college and the medical campus. This week, they offer a Q & A on their “”https://green.harvard.edu/shut-sash-insiders-guide">Shut the Sash’ program:
Started in 2005, Shut the Sash now includes 20 labs and counting, and saves roughly $250,000 annually in energy costs. Due to the incredible success of the program, many want to know how it was started and how it is run. Below are some common Q&A to provide insight into one of our most successful programs.
1. What is the type of data that you use for trending the competition?
We measure average CFM from the hood exhaust system. Our program is set up to collect data every 30 minutes, so we have 48 points for each day. We have 20 labs in the competition currently. Each lab may have a different amount of fume hoods that are part of the competition- some have one hood participating, others have eight or more- it doesn’t matter how many hoods are being tracked, since the goal is to reduce their own total values. Regardless of how many hoods they have, we sum their data points in the report, so we are always looking at the total exhaust for each lab- we compare hood to hood within the labs. Their improvement is looked at as a percent of their total value.
