| Résumé: | This document presents a comparative study of the percentage of time that the operating temperature is located within the limits of the comfort zone proposed by ASHRAE Standard 55-2010 for naturally ventilated buildings. The temperatures studied were recorded inside of experimental roof pond modules, located in a warm, dry climate. Five passive cooling techniques were applied to the modules. The experiment was carried out in Chihuahua, Mexico (Lat.: 28N, Long.: 106W, altitude: 1,425m) during the summer of 2012. The results indicate that roof ponds are an excellent alternative to increase the percentage of hours of comfort, because they provide up to 30% more hours on average with respect to a control module without a roof pond. If radiative cooling is added at night, the percentage increases to 40%, and incorporating thermal mass it increases up to 65%. Even, in some cases, the cooling is so intense that it exceeds the lower range of comfort in morning hours. |
