Abstract: This study is part of a wider research aimed at creating building type databases for simplified dynamic thermal models of buildings. In particular, thermal inertia analysis is the focus of this paper, looking at its impact in terms of comfort and energy consumption in different climates and for different end uses. The impact of all factors influencing thermal inertia are investigated using dynamic simulations. Its relevance in warm climates has been observed, especially influenced by periodic transmittance and internal capacity. Combined with a passive strategy as night ventilation, the discomfort level with cooling system can be reduced up to 90%.
