El objetivo del presente trabajo es evaluar experimentalmente el desempeño térmico de un Módulo Experimental de Vivienda (MEV), construido en la región Alto Andina, mediante la evaluación sistemática de doce configuraciones de operatividad diferentes, desde el manejo nocturno de contraventanas hasta actividad humana, uso de cocinas a gas y uso de dos sistemas de calefacción solar activos. Este objetivo se fundamenta en las mediciones de temperatura y humedad, considerando la primera como el parámetro principal de análisis térmico para verificar el desempeño térmico del MEV mediante la variación de la temperatura interior respecto al exterior, según la configuración del MEV dado a que la variación entre la temperatura diaria promedio interior y exterior muestra la eficacia de las estrategias de calentamiento o enfriamiento. En base a ello, los incrementos de temperatura en...

This article aims to evaluate the thermal behavior of a construction system consisting of fired red clay brick walls with cavities, commonly used in large cities in Peru and increasingly adopted in high-altitude Andean areas without being evaluated for frost climates. Consequently, an experimental module was constructed at a real scale at 4500 masl. The experimentation carried out over 49 days shows that the thermal delay and decrement factor are 4 hours and 0.27, respectively, with the daily hourly average thermal amplitude indoors being 6.4°C and outdoors being 17.1°C. Additionally, the numerical study using EnergyPlus software and the implementation of the equivalent model of a set of homogeneous layers for heterogeneous materials, which dynamically considers the heat transfer modes by conduction, convection, and radiation, achieve good agreements of the indoor temperature between t...

This paper analyzes the different thermal and dynamic energy contributions of the different proposals for modifications made in the envelopes of two experimental housing modules built in the town of Imata, Arequipa at 4519 meters above sea level. The modules were built with constructive characteristics of the place and typical design, later modifications were made such as changing the roof covering material, plastering the adobe walls with plaster, placing skylights on the ceiling and false ceiling, insulation of the false ceiling, and construction of a greenhouse attached to one of the modules. The data recording consisted of measuring the indoor air temperature of the modules and attached greenhouse, in addition to the outdoor meteorological data recording using a Davis station located at the top of the Imata municipality. The average daily indoor air temperature of the module without ...

In recent decades sandwich composites have taken a greater share in the construction industry, due to their low cost and properties that characterize these composites. Among the most important properties of these, the thermal conductivity stands out, which is directly linked to the individual's thermal comfort in a building. Currently, the Peruvian State has been developing projects in the fight against frost and cold, where one of the main interventions focuses on the construction of sustainable homes that can help the high Andean population cope with the inclement cold. In this sense, it is necessary to have construction materials appropriate for the climatic conditions of the place, and that is where lies the importance of this research. This paper proposes the study of thermal conductivity at temperature conditions close to 0 ºC of sandwich composites formed from monolithic material...
