- Description
- The increased emphasis on Green House Gas emissions and global warming has given greater impetus to the development of energy efficient housing in Australia. The emphasis in design has traditionally been placed on the thermal resistance of the building components with little consideration of the benefits of thermal mass in ameliorating the effects of the extremes of temperature experienced during the normal diurnal cycle. The full thermal benefits of the heavy components of composite walling systems have therefore not been obtained. This paper describes a novel methodology for defining the thermal performance of housing under dynamic weather conditions. The concept is called dynamic temperature response theory and inherently considers the properties and an appropriate configuration of the insulation and thermal mass within walls when being exposed to typical temperature fluctuations. This is a novel approach which accurately reflects previous findings that masonry construction significantly reduces heating and cooling loads. It also highlights the fact that heavily insulated lightweight construction, with high thermal resistance but low thermal mass, does not perform as well as masonry construction in moderate climates, especially if passive solar design principles are utilized. Examples of how to accurately balance thermal mass and insulation properties in housing are discussed in the paper. This can be used to advantage in both new dwellings and in the retrofitting of existing houses to improve their thermal performance and minimize the need for artificial heating and cooling.
