This study examines the influence of ventilation on chemical reactions among indoor pollutants. We have used a one compartment mass balance model to simulate unimolecular and bimolecular reactions occurring indoors. The initial modeling assumes steady-state conditions. However, at low air exchange rates, there may be insufficient time to achieve steady-state. Hence we have also modeled non steady-state scenarios. In the cases examined, the results demonstrate that the concentrations of products generated from reactions among indoor pollutants increase as the ventilation rate decreases.
The wish to improve the energy performance of a building as well as to improve indoor climate can be mentioned as one of the main driving forces behind the introduction of so called 'double facades'. Various types of double facades can be distinguished; the number of possible double facade variants is large. This raises the question in what way the performance of double facades can be predicted during the design process and how well-considered design decisions can be made.
