Work methodology for ecological design strategies in hot humid climate of Mexico

Abstract

The need for people’s comfort has always led us to modify our environment, within this search for comfort we find thermal comfort, of a state of mental satisfaction with the environment. In places with warm-humid climate, such thermal comfort is difficult to achieve during several seasons of the year, due to the high temperatures that are accompanied by high levels of humidity, causing hot flashes. This essay is focused on expressing some of the problems that appear in the implementation of some passive air conditioning systems for housing projects with the climate in question, as well as some possible solutions to be analyzed. A simple methodology of passive design strategies, or low power consumption, to reduce temperatures and humidity is exposed. In the case study, Villahermosa, Tabasco, only ideal conditions are available approximately 4.73% of the time, while the high humidity levels remain throughout most of the year. The strategies analyzed in the article are: solar protection, natural and mechanical ventilation, passive and active low enthalpy geothermal, desiccant panels and the collection of water from dehumidification. The implementation of Peltier cells in dehumidification processes is proposed, which help to condense the water vapor contained in the air, so that when entering the homes, it is more comfortable.
