The system exhausts air from the house, thus causing a change in pressure that pulls in make-up from the outside through leaks in the building shell and intentional, passive vents. Exhaust ventilation is most appropriate for colder climates, since in warmer climates, depressurization can draw moist […]

Supply ventilation systems use a fan to pressurize a structure, forcing outside air into the building while air leaks out of the building through holes in the shell, bath and range fan ducts, and intentional vents (if any exist). Like exhaust ventilation systems, supply ventilation systems are relatively simple and inexpensive to install. A typical
