摘要

热致变色材料具有随温度变化的光学特性，可优化建筑围护结构对太阳能的利用，以提高能源效率。本研究的目的是确定热致变色砂浆（TM）外墙涂层对地中海气候下建筑能源性能的影响。提出了一种新的计算方法，用于在传统的高能模拟工具中实现砂浆的动态光学特性。本研究考虑了具有可变光学性质的涂层，其太阳能吸收率值从0.65变化到0.60，转变温度从20℃变化到35℃。砂浆在低温时呈深灰色，在高温时呈浅色。涂有TM涂层的建筑显示出3 % 年能源需求低于具有不可变光学特性的建筑，最大供暖需求减少量达到8 %.

Revestimiento de mortero termocrómico en fachada: impacto en la eficiencia energética del edificio

Thermochromic materials, with optical properties changing with temperature, optimize the use of solar energy by the building envelope for the improvement of energy efficiency. The purpose of this research is to determine the impact of a thermochromic mortar (TM) facade coating on the building energy performance in a Mediterranean climate. A new calculation methodology is proposed to implement the dynamical optical properties of the mortar in conventional energetic simulation tools. This study considers a coating with variable optical properties that move from 0,65 to 0,60 solar absorptance value, and a transition temperature moving from 20oC to 35oC. The mortar shows a dark grey colour for low temperatures and a light colour for high temperatures. The building with TM coating shows a 3 % lower yearly energy demand than the building with non-variable optical properties, with a maximum heating demand reduction reaching 8 %.
