- Description
- This paper describes an experimental investigation of internal and external surface temperature variations of heavy and lightweight walling systems under the influence of moderate weather conditions typical of the Australian climate. Four housing test modules incorporating various walling types were built on the University of Newcastle campus and the detailed thermal performance of each system was measured over a range of seasonal conditions. The temperature gradients for various locations through the thickness of each wall assemblage are examined and discussed. The analysis helps to provide an increased understanding of the dynamic behaviour of various walling systems subjected to real weather conditions, with the preliminary study demonstrating that wall thermal resistance (R-value) is only a steady state parameter which is not capable of representing the thermal performance of lightweight and heavy walling systems as a sole descriptor. The investigations indicate that energy demands for Australian weather conditions are influenced by the combination of the thermal mass and the thermal resistance of the wall components, and both need to be considered if the thermal performance is to be realistically predicted.
