Diagnóstico térmico y energético de edificios municipales en clima subtropical húmedo

Abstract

Con un proyecto Euroclima de la Unión Europea, se auditaron con fines de rehabilitación energética cincuenta edificios municipales en diversos municipios de 5 provincias argentinas. Se presentan resultados de casos en la provincia de Misiones que tienen la particularidad de encontrarse en clima subtropical muy cálido y húmedo correspondiente a la zona Ib de la Norma IRAM 11603. Los edificios que presentamos fueron auditados al igual que otros durante 7 días en meses de invierno y verano. Mediante micrologguers se evaluó su comportamiento higrotérmico junto a la demanda de energía a lo largo de un año utilizando un modelo informatizado ad-oc. Se propusieron mejoras y se evaluó la reducción esperable en demanda de energía y emisiones GEI potenciales. Se exponen los resultados junto a conclusiones.

Under a European Union Euroclima project, fifty municipal buildings located in various municipalities across five Argentine provinces were audited for energy retrofitting purposes. This paper presents results from case studies conducted in the province of Misiones, which is characterized by a very hot and humid subtropical climate corresponding to Zone Ib of IRAM Standard 11603. The buildings presented here, together with others, were monitored over seven-day periods during both winter and summer months. Their hygrothermal performance was assessed using micro-loggers, and annual energy demand was evaluated through an ad hoc computerized model. Improvement measures were proposed, and the expected reductions in energy demand and potential greenhouse gas (GHG) emissions were estimated. The results are presented and discussed, followed by the main conclusion.
