Diseño térmico de una vivienda de bajo consumo energético a ser construida en la ciudad de quito validado mediante indicadores de confort adaptativo de la norma ashrae 55.

Abstract

n residential houses in Quito, it is common to feel thermal discomfort because of low indoor temperatures, as several studies have shown. This discomfort can affect the productivity and the quality of life of the inhabitants. For this reason, it is important to study the thermal behavior of homes from the design stage to improve their indoor environment. The objective of this work is to maximize the number of hours of annual comfort of a house to be built in the city of Quito using the energy simulation software eQuest. The research has structured in four main phases: 1) creation of the reference model of the house using a conventional construction system used in Ecuador, 2) evaluation of the reference model based on the adaptive comfort model of the standard ASHRAE 55, 3) implementation and analysis of passive strategies aimed at improving the thermal comfort of the home and 4) comparison between the new design proposals and the reference model. The results show that in the base model, most of the spaces are subject to thermal discomfort around 75% of the year. The spaces of the first floor are the most affected because of the floor border condition. After implementing passive strategies, it is possible to significantly increase the hours of thermal comfort in the house, especially in critical areas, thus achieving an environment that provides a better quality of life to its occupants.
