Extensive green roofs thermal effect and energy saving indoor by cooling

Abstract

This work analyzes the thermal effect of extensive green roofs (EGR), in different climatic conditions of eight cities in Mexico. A house is simulated and temperature, comfort sensation and air conditioning energy consumption are analyzed. The results show that the extensive green roof helps to decrease the maximum interior temperature, especially in the rooms located on the upper floor, where greater energy saving for air conditioning (cooling) is also observed. In all the cases studied, EGRs contribute to achieve thermal comfort conditions; in fact, their implementation under some climatic conditions avoids the use of air conditioning.
