Abstract: This paper presents a simplified modelling process by using experimental results to form empirical relationships for a particular novel Monodraught natural ventilation and cooling system which can be applied in a popular building simulation software TAS. In particular, the behaviour of Monodraught natural ventilation Windcatcher systems integrated with a DC fan that is supplied directly by a PV panel without a backup battery is modelled for the whole year. The effect of natural and night time ventilation with thermal mass for cooling and mitigating overheating are investigated. Pressure losses from opening, louvers, ducts, dampers etc are accounted for and simplified in the modelling process.
