Energy Performance of Dwellings in a Temperate Climate Area of Argentina. An Architectural Proposal

Abstract

Aim: The research aimed at carrying out a global comparative synthesis of the results of monitoring thermal energy behavior of single-family dwellings and apartments located in the city of Santa Rosa, La Pampa, Argentina; and describing an architectural proposal that considers use of resources (land, morphology, materials and energy), lifestyle of inhabitants (qualitative variables) and critical analysis of the historical problems of the housing deficit in Argentina. Methods: The work includes a typological analysis of clusters of dimensional, morphological and thermo-physical indicators, energy performance and inhabitant’s behavior. Regarding energy heating consumption, multifamily buildings consume 52% less energy than the average single-family dwellings. Results: An architectural proposal taken into account the use of resources and energy efficiency strategies to give an answer to the housing deficit of the area under study showed that the densification of housing provides significant energy and economic benefits, especially if one incorporates passive solar design principles. Apartment blocks (B) and single-family dwellings (H) show 114.3 and 47.6 dwelling/hectare, and as a result, 39.4 and 16.4 inhabitant/hectare. Conclusion: Heating energy saving of B in relation to H is around 32% and the envelope’s cost is reduced to 47%. Argentina’s energy scenario, the possibility of reviewing regulations and building codes, the region’s growth trend in housing construction, the process of building labelling, among others, require a thorough analysis of the information on characteristics of building stock and its energy performance.

Evaluación Energética y Económica de Calefacción de Hogares por Bomba de Calor en Bariloche, Montevideo y Santiago

“…En hogares bajo el clima frío de Bariloche (8,3 °C de temperatura media anual y 3.665 grados-día anuales de calefacción, tomando 18,3 °C como valor de referencia para el cálculo del déficit de grados-día según Eto (1988), en adelante "grados-día", lo cual será definido en la sección siguiente), el mayor consumo de energía se debe a calefacción (80 %), como han señalado otros autores (González et al, 2007;Sulaiman et al, 2020). Del 20 % restante el mayor consumo se debe a agua caliente sanitaria, en donde recientemente se han propuesto mejoras de eficiencia empleando sistemas convencionales (Juanicó y Bove, 2020) o bombas de calor (Juanicó y Bove, 2021).…”
