Alex Sylvester is a MASc student in Mechanical Engineering working with Dr. Sheldon Green and Dr. Steve Rogak. He is working on improving current membrane Energy Recovery Ventilator (mERV) technology.

mERVs are building ventilation systems that use the heat and moisture in exhaust air to partially condition intake air. They do this by running the two streams of air through adjacent flow passages separated by thermally conductive and porous membranes. mERVs are especially remarkable because they are selectively permeable to water vapour and do not allow harmful contaminants to recirculate. Alex is using computational and experimental methods to design better mERVs that take advantage of the interdependence between flow channel geometry and membrane properties.
