Incorporación fotovoltaica y estrategias pasivas para lograr máximo aprovisionamiento y alto estándar energético en clima tropical ecuatorial

Abstract

This research is based on the constant high energy demand that a single-family home located in a tropical equatorial climate requires to sustain the usual electrical consumptions and achieve interior thermal comfort. To perform this study, a series of bibliographies were reviewed and a survey of information was carried out onsite; additionally, a digital review of the electrical grids was performed. Once the house and its surroundings had been defined, a redesign proposal was put forward, maintaining the location. In search of the Net Zero standard, passive design strategies were applied, including cross ventilation, a ventilated roof and facade, an indoor courtyard, and solar radiation protections. Subsequently, through computer tools such as DesignBuilder and Ecotec, bioclimatic analyses were carried out, supplemented with the data

reflected in the electrical grids of the single- family home in two periods: monthly and annually, corresponding to pre-pandemic conditions and the current pandemic stage. These tools served to replicate the same bioclimatic simulations in the redesign and demonstrated a significant change; this was reflected by the reduction of energy consumption compared to the demand generated by the existing home. With the aforementioned results, and by using the System Advisor Model (SAM) tool, in order to supply the base consumption of the redesign, a total of 9 PV panels (Net Zero standard) are required. However, due to the available area on the roof, the Plus Energy House standard of 18 panels were proposed, which would supply enough additional energy to power an electric vehicle and two scooters. In order to reach the maximum Plus Energy House standard, 22 PV panels would be installed, which would cover the maximum capacity of the roof and reduce dependence on fossil resources.
