In order to achieve low energy housing, it is important to quantitatively and comprehensively determine the effectiveness of energy saving technologies and to evaluate the energy conservation performance of an entire house.

Purpose / Context - The purpose of this study was to develop a prevention strategy against fungal attack in any residential building, which had been previously proposed and applied to conserve cultural assets using a fungal index. The strategy consisted of four stages: current status assessment, diagnosis, preventive measures, and finally confirmation of the preventive...

Problem: Roofs receive the most intense solar heat load among all building envelope surfaces in Equatorial-region. Solar heat gain through roof contributes to a significant portion of building heat load. In tropics where building cooling is needed all-year-round, passive methods to reduce heat gain through roof could provide significant cooling energy-savings. Approach: Currently, the most...

Purpose / Context - The characterisation of the residential building stock existing in Australia in terms of attributes relevant to energy performance is increasingly an important task for planning and policy purposes. There is a lack of information and documentation on the energy performance characteristics of the existing residential stock in Australia, particularly those constructed...

Purpose / Context - It is important to estimate the number of people remaining in a room to allow for modification of the room environment and effective energy use. Methodology / Approach - A prototype of an automatic estimation system consisting of a general-purpose microcomputer and environmental sensors (e.g., a thermometer, hygrometer, and CO2 concentration...
