Mejora del desempeño térmico del muro trombe a través de un acristalamiento electrocrómico con conmutación programada = Improving the thermal performance of the trombe wall through programmed switching electrochromic glazing

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 ™, 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.
