multi-zone building model

Ventilation systems are primarily designed for ensuring good indoor air quality (IAQ). However, building energy requirements tend to put demand on reducing air change rates. The assessment of the performance of ventilation systems over long periods has thus become a subject of importance. In this framework, five ventilation systems were investigated for a heating period in a single-family house using a representative occupancy and pollution schedule. This was undertaken using SIMBAD, a combined mass and heat transfer toolbox. This paper compares the different results.
