Integración arquitectónica de sistemas solares activos y pasivos en edificios industriales. Caso estudio Cuenca-Ecuador

Abstract

The industrial energy consumption in Ecuador mainly demands Diesel (38%) and electricity (31%). 58% of electricity comes from water sources and the rest from thermoelectric plants. In view of this, the hydroelectric development continues and, despite being assumed to be a clean source, it represents relative impacts against the nature. The energy self-production in situ from renewable sources is an alternative for continuing with the energy expansion of the country. A promising, clean, renewable and of gigantic potential source in our country is the sun, due to its strategic geographical location. The proposed work has the aim of determining the feasibility of integration of active solar collectors and passive design strategies in industrial buildings of Graiman, in Cuenca-Ecuador, promoting the reduction of consumption, as well as physical comfort. To do this, the existing solar technologies and passive strategies for industrial buildings. The current state of buildings, location and energy demands is analyzed. From this analysis, it is developed an envelope proposal made that would be applicable for most of the buildings of the industrial venue and the total photovoltaic energy production that could have been achieved with the irradiation measured during 2016 is estimated. The obtained results show that it can be supplied the 22% of the electricity demand of the industry, reducing almost 3 tons of CO2 per year and saving $ 712,131.23 per year in electricity costs, providing a methodology to be applied in an architectural design process that is considered as renewable energy.
