Design Strategies for Residential Ventilation Systems

Since installing an adequate ventilation system was integrated in new constructions was included in the building code in 2006, a lively pubic debate about the performance and even about the use of ventilation systems developed on different platforms. In the mean time, demand controlled ventilation and air-to-air heat exchangers have secured important and heavily competitive shares in the market for residential ventilation systems.
The analysis of the performance of residential ventilation systems presented in this dissertations demonstrates that the design strategies included in the current building codes result in sub-optimal performance. At the same time, it shows the large potential of demand controlled ventilation and of air-to-air heat recovery to improve this performance. The conflicting conclusions from different aspects of bedroom indoor air quality, on the other hand, underscore the need for further research in this field.
