Evaluación energética y rehabilitación de la envolvente edilicia de una escuela en zona bioambiental templada cálida, Argentina

Abstract

The objective of the work is to identify potential energy savings from different proposals for the retrofitting of the envelope of a school building located in the city of San Juan, Argentina. The energy behavior is analyzed from the historical consumption of electricity and natural gas. The thermal properties of the closings are evaluated and the energy indicators are calculated in stationary regime. In order to solve the problems of constructive materiality, proposals that allow the components to achieve the thermal transmittance values suggested by the IRAM 11605 Standard in the recommended and average levels of thermal comfort, are developed. The results achieved shows that Optimal Rehabilitation projects a 55% reduction in energy requirements for heating. However, Medium Rehabilitation, with savings of 47%, is positioned as the most convenient one, when also is considered current economic construction costs.
