Abstract
The indoor thermal environment of buildings influences people’s health, well-being and productivity, as well as energy consumption. The importance of thermal comfort in buildings has been recognized for decades. However, this aspect is still incipient in the Colombian construction industry, especially in housing projects. In this research, the thermal performance of three common housing types in the city of Medellin was analyzed. To do this, the operative temperature, the predicted mean vote (PMV) and the predicted percentage of dissatisfied (PPD) were calculated in accordance with ISO 7730:2005. The results showed that the thermal inertia of two of the three types of housing examined was insufficient to offer adequate thermal conditions, despite the temperate climate of the Aburra Valley. These results warn about the vulnerability of urban population in Colombia to extreme temperature fluctuations.
