Modelling the influence of ventilation strategies on air distribution and heat loss in a single family dwelling.

Uses a validated multi-cell mathematical model of air infiltration to analyse the influence of various ventilation strategies on air distribution and energy demands. Assesses the performance of both natural and mechanical systems for two sets of climatic conditions and for two levels of airtightness. Shows that natural ventilation rates are highly dependent on climate. Additionally, air movement is a function of wind direction and stack effect. Mechanical ventilation provides good air distribution but climatic conditions have an important influence on its potential for cost effectiveness.
