PDFResumen
El gasto energético que representa la climatización de edificios a nivel mundial hace necesaria la adopción y adaptación de técnicas pasivas para reducir las demandas de calefacción y refrigeración. Diversos estudios han comprobado los beneficios térmicos y energéticos del muro Trombe (MT), sobre todo en climas continentales. No obstante, este sistema genera sobrecalentamiento en climas con veranos cálidos. Mas allá del uso de sistemas tradicionales, esta técnica puede mejorar su capacidad de climatización en este tipo de climas a través de materiales cromogénicos como los vidrios electrocrómicos (EC). En este estudio se simula la rehabilitación energética de una habitación en un edificio de Madrid mediante un MT convencional (MTC) y uno que incluye un vidrio EC (MTEC), cuya conmutación fue programada para mediar las condiciones climáticas en un periodo con mayor contraste diario de temperatura. Los resultados muestran que el MTEC proporciona temperaturas interiores más confortables.
Abstract
The energy cost of air-conditioning buildings worldwide makes it necessary to adopt and adapt passive techniques to reduce heating and cooling demands. Several studies have proven the thermal and energy benefits of the Trombe wall (TM), especially in continental climates. However, this system generates overheating in climates with hot summers. Beyond the use of traditional systems, this technique can improve its climate control capacity in such climates through the use of chromogenic materials such as electrochromic glass (EC). This study simulates the energy rehabilitation of a room in a building in Madrid using a conventional MTC (MTC) and one that includes an EC glass (MTEC), whose switching was programmed to mediate the climatic conditions in a period with greater daily temperature contrast. The results show that the MTEC provides more comfortable indoor temperatures.
