Percepción de confort térmico mediante la caracterización de la envolvente de edificaciones residenciales en la ciudad de Loja

Abstract

Abstract: The implementation of the NEC-HS-EE standard is essential for the regulation of buildings in terms of energy efficiency and thermal comfort. The main requirement is the thermal transmittance of the envelope elements, therefore, the present study validates the maximum values established for the city of Loja, and determines if these are necessary to guarantee that the perception of thermal comfort in residential buildings is acceptable. The research is based on the information from the ENED building survey, the application of thermal sensation surveys and envelope characterization, and the calculation of thermal transmittance using the ISO 9646 theoretical calculation method. The results show that the construction packages of the Predominant typologies T1 and T2 comply with the regulations and provide a satisfactory sensation of comfort to the occupants, with the exception of the 7cm thick brick wall, which is a common practice. The best thermal behavior in the typologies occurs on the upper floor both during the day and at night, while the least comfort is recorded on the ground floor at night.
