Air Intake and Exhaust Design
Novus conducts studies to help prevent air pollution from impacting air-sensitive locations on buildings including fresh air intakes, operable windows, entrances and other pedestrian areas. This is accomplished by reviewing architectural drawings, local building geometry, and mechanical details pertaining to equipment type and location. Modelling is then undertaken to determine wind flow patterns around buildings and over rooftops, and the resulting effects on the dispersion of emissions and odours. If pollutants or odours are predicted to reach undesirable levels at fresh air intakes or other air-sensitive locations, detailed guidance is provided for improving design configurations.
Assessments include the use of building wake dispersion equations published by ASHRAE and wind-tunnel modelling, and are most often applied in healthcare and laboratory building design.
