Introduction
Fume hoods are self contained cabinets that are usually found in laboratories. They are used to discharge harmful gases from labs out into the atmosphere, and are generally run constantly to ensure that these harmful gases do not get inhaled by scientists. One fume hood consumes as much energy as if not more energy than a typical house, according to the Lawrence Berkeley Lab [1]
Data Collection
The following data should be collected about each fume hood to allow for the most thorough evaluation.
- cooling & heating degree days
- face velocity (fpm)
- face opening size (width by height)
- cfm
- W/cfm
Assessment Recomendations
- coming!
