Analysis And Comparison of Overheating Indices in Energy Renovated Houses

The scientific literature offers a number of methods for assessing the likelihood of overheating in buildings. The paper calculates eight welldocumented 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.
