In this study, the effect of the thermal mass and thermal insulation of a ventilated building onthe indoor environment is investigated. A simplified model of the thermal interaction between a building structure and the interior is developed. Three important parameters are determined, and analytic expressions for the attenuation and phase lag of harmonic external forcing are derived for an unventilated interior. The effect of forced or stack-driven natural ventilation on the interior response is then investigated.
