Abstract
In order to achieve greater enhancements in energy sustainability for housing, the function and efficiency of two different passive cooling systems were studied: encapsulated water in recycled bottles of Polyethylene terephthalate (PET) and polystyrene plates, in comparison with standard concrete slab systems, which are customarily used in housing. Experiments were placed over a tile surface, in which temperature changes were monitored for a period of 20 days from 08:00 to 20:00. The efficiency of passive thermal storage systems was endorsed through statistical analysis using the “SPSS” software. This resulted in a 17% energy saving, thus promoting energy sustainability in housing units, which reduces the use of electrical appliances required to stabilize conditions to achieve optimum thermal comfort for the human body inside a house, therefore, reducing electrical power consumption, CO2 emissions to the atmosphere and generating savings. Due to the complexity of a system with temperature changes, a fractal analysis was performed for each experimental system, using the “Benoit” software (V.1.3 with self-compatible tools of rescaled range (R/S) and a wavelets method), showing that the thermal fluctuations on the tiles with the thermal storage system adapt to the rescaled range analysis and the regular tiles adapt to the wavelets method.

Summary
As a part of a globalized society, have been topics of debate since 1970, and solutions for destructive effects in the planet have been researched [1,2]. Experts are interested and making efforts to take actions that allow energy sustainability in housing through the implementation of new technologies that can help mitigate the negative effects of climate changes. The number of wind and solar technology patents has increased by 20% and 15%, respectively, on a global basis since 2000 [2,3,4]. Solar radiation is one of the most crucial factors, as are: atmosphere circulation, ocean currents, the geometry of orbital planetary movements, snow-covered surfaces, and the physiographic characteristics of each place, and so forth [5]. Constructions/ buildings are always exposed to the climate conditions of the place where they are located, constantly receiving a thermal energy interchange, whose main source is solar radiation, which influences the elements that shape the building, which, along with thermo-physical properties of materials, establish the thermal performance of the enclosure [6,7]
