本文提出了一种利用保温材料提高建筑节能的解决方案。该应用在巴西东北部平均气温达到34°C的地区进行了测试。这项研究考虑了该区域的建筑材料，例如：（a）石膏，自然界储量丰富，在巴西的几个矿床中发现，具有吸水性;（B）蛭石，一种由铝和镁的水合硅酸盐组成的矿物;（c）伊娃，一种乙烯-醋酸乙烯酯，作为制鞋业膨胀片材切割的残余物大量生产。测量了每种材料的热导率，但两种壁的热行为的比较仅基于计算。这些材料在涂有空气层的板中的应用表明，与传统的墙壁相比，当使用蛭石组成的灰泥时，每平方米的热负荷减少38%，当使用石膏或伊娃组合物时，每平方米的热负荷减少41%。
This paper presents a solution for improvement of energy efficiency in buildings by using thermal insulation materials. The application was tested in areas of northeast Brazil where the average temperature reaches 34°C. The research considered building materials from the region such as: (a) gypsum, that is abundant in nature and found in several deposits in Brazil and it is absorbent of water; (b) vermiculite, a mineral composed of hydrated silicates of aluminum and magnesium; (c) EVA, an ethylene-vinyl acetate produced in large quantities as residue from expanded sheet cuttings in the shoe industry. The thermal conductivity of each material was measured but the comparison of the thermal behavior of the two walls is based on calculation only. The application of these materials in plates coated with a layer of air showed, compared to conventional walls, 38% reduction in heat load per square meter when using vermiculite-composed plaster and 41% reduction when using gypsum or EVA composition.
