Abstract

The scientific literature offers a number of methods for assessing the likelihood of overheating in buildings. The paper calculates eight well-documented indices for four representative family houses, from moderate and temperate climates, under different renovation processes (66 variants), with the use of multi-zone energy software. In two out of four cases, the calculation included passive cooling measures for optimization purposes (shading, ventilative cooling). The analysis shows strong correlations between different methods-indices originating from the same comfort model theory independently of the climate and the building geometry. Finally, many indices correlated highly with the annual building heat gains and losses.
