Applying a comfort model to building performance analysis

This paper considers the application of comfort parameters as a mechanism for building performance analysis and control. It challenges traditional methods of evaluating zonal comfort through thermostatic dry-bulb temperature alone. In contrast, it creatively applies a 'calibrated' Comfort Tool software to measure comfort improvements in buildings. A comfort cart built according to ASHRAE-55 standards together with thermal imaging surface temperatures is combined in a comprehensive thermal performance analysis in buildings. This paper is about demonstration and discussion in the development of a measurement and analytical process which is a systematic approach towards spatial comfort improvement. Two houses were measured and analysed, over an extreme daytime period in Darwin, Australia. Improvement in overall thermal conditions of up to 35% and 59% were realised with the most reliable potential for thermal improvements found in surface temperature (mean radiant temperature), conditioning changes indicating between 32 - 38% overall comfort improvement in the building.
