Yes, behavior is very difficult to change, and the stickers work pretty well over the long term. Some students at MIT developed a "MASH" alarm which had excellent compliance (under 10% open), and cost about $15 to make. The University of Alabama Birmingham is also using them. INstallation is...
To be more accurate, an 8' fume hood blows 1200+ cubic feet per minute when open, and 400 CFM when closed (if the HVAC modulates). The amount of energy it takes to condition that air from outdoor ambient is quite astounding, and more likely equivalent to 3 houses.
If you work in a building...
thanks for the greetings Russ.
You are in great company if you spoke with my good friend Allison. She is amazing, and brought much of the early work in Green Labs to a professional level. The movement continues to mature and blend with core mission of research and operations, as it must...
Thanks. It feels like the most important contribution I can make for climate protection. The other contribution is getting the GWP drivers below 1 W/SF worldwide, and talking to our families, policy makers, businesses and faith leaders.
Measuring Ventilation Effectiveness in laboratories at a world leading research university so we can optimize safety and reduce waste. "Air Change" does not necessarily mean air flush!
I want to compare diffusion of a tracer gas with a low exposure limit (e.g. isoflurane) to the advection of air by a ventilation system. When will diffusion exceed advection? I can't make sense of diffusion constant to compare transfer rates or velocities.
At room temperature the diffusion...
I'm a basic chemist and sustainability champion trying to use essential principles in ventilation safety to provide optimum ventilation for vapors, gases, and even infectious aerosols (e.g. SARS Co-V). Laboratories have 5x the energy demand per M2 as offices, so conservation there makes a big...
