Performance of domestic ventilation systems: A simulation study

Multi zone computer simulation is used to predict the concentrations of carbon dioxide, carbon monoxide, formaldehyde and water vapour in a flat and detached house, fitted with five different ventilation systems all of which comply with current building regulations for England and Wales. Results show that, understandably, the different ventilation systems produce different spatial and temporal pollutant concentrations. A method based on equivalent ventilation rates for each pollutant is used to optimise the specification of the ventilation systems.
