LoginMinimising ventilation for energy conservation in buildings requires that ventilation efficiency be high. The common practice of locating supply outlets and return inlets in or near the ceiling creates an opportunity for air tobypass from the supply to the return without mixing in the occupied space. Equations are derived for calculating efficiency and stratification factor from tracer gas decay measurements.
