Evaluación del confort higrotérmico, calidad del aire interior y ventilación de una vivienda unifamiliar y propuesta de rehabilitación pasiva

Abstract

Abstract: Hygrothermal comfort and the air quality of a building are two of the indicators of the indoor environmental quality that determines the well-being of the occupant. The present investigation selected a single-family home as a case study to validate a methodology of evaluation of these parameters in existing buildings that consisted of the analysis climate of the place, in situ measurement campaigns of temperature and relative humidity determining thermal discomfort when the temperature outside was more extreme, these Results were statistically compared with the EcoDesigner simulator reports. A sensor was also used to measure the concentrations of CO2, TVOC and HCHO, without find alarming values ​​on typical busy days. Surveys were applied satisfaction and thermal sensation of the occupants and compliance or non-compliance with the minimum requirements of the constructive packages of the envelope that, due to their scarcity compliance it was proposed to improve the opaque elements by using XPS as an insulator on upper floor walls and cardboard gypsum panel covering with an air chamber going down thermal transmittance values.
