SR89 Summertime overheating in New Zealand houses - influences, risks and mitigation strategies (2007)

This study was designed to examine which physical and climatic parameters influence the amount and severity of summertime overheating in domestic buildings both in terms of time and temperature.

Three 'typical' New Zealand houses were modelled altering the parameters of location, climate, thermal mass, insulation levels, orientation, shading and ventilation. It was found that external temperature has by far the greatest impact on indoor temperature, followed by ventilation rate.
