Abstract
The electrical energy consumption of buildings when using air conditioning or refrigeration systems represents 60% of the energy consumed in buildings. The cooling and ventilation system of an environment plays an important role in the comfort of the user, but it should not necessarily be an energy consumer, this can be solved with passive envelope alternatives, the ECO COOLER system is analyzed as a passive design strategy to cool living environments reducing the amount of energy consumption through lattices on facades located in tropical climates. A bibliographic review of the thermal behavior of a clay pot is made, and a conceptual model is elaborated to measure temperatures with a variable free facade and envelope with a lattice of clay pots, which are subjected to a heat gun to demonstrate the temperature variation. This element has a peculiarity in its material and composition, which is porous and the process that happens to its interior is to cool by the effect of evaporative cooling, the porosity of the clay pot causes the water to filter and evaporate, lowering the temperature of the remaining water. The factors for cooling depend on the environmental conditions, the hotter the environment, the faster the evaporation, this method is known as the "botijo effect". A prototype of a clay pot with characteristics of sweating, storage and overflow system for self-filling is proposed and the lattice envelope is applied on a facade, the passive strategy ECO COOLER by clay pots, fulfills the purpose of cooling spaces without the use of electricity, reducing the consumption of appliances such as air conditioning, an appliance of high energy demand today. Area of science: architecture.
