Lowering the sashes on laboratory chemical fume hoods (CFHs) can result in significant energy cost savings by reducing the volume of room air that has to be heated or cooled. This project will evaluate the resources, components, and best practices required to develop a model shut the sash program and implement it campus-wide for variable air volume (VAV) CFHs. If successful, the project could generate over $250,200 in annual cost savings. Thus, the Student Sustainability Committee is in favor of funding the full requested amount of $4,400.
