With the trends of comfort modelling moving more towards the application of Adaptive Models, the influences of several parameters as used in the traditional ISO7730 standard are therefore non-existent. The proposed work considers the conventional ISO 7730 standard as conservative in its calculation; however extremely useful, in cases where actual measurements of spaces are considered (ISO 7730, 1994). Measurements from a comfort cart built according to ASHRAE-55 standards (ANSI/ASHRAE 55, 2005) together with thermal imaging temperatures are combined. In doing so, an ISO 7730 thermal comfort assessment applying the CBE – ASHRAE 55-2004 Comfort Tool allows for changes in the environment to be examined for improved comfort (Huizenga, 2006; Tyler et al, 2017). Results for two cases in a severe Darwin climate yield an improved PPD by 2.5-2.7 times when implementing extremely low- energy measures.
