Global demand for energy in the construction sector has increased drastically. A substantial portion of this energy belongs to fulfilling the heating, ventilation, and air-conditioning requirements of buildings, which are essential for maintaining the well-being of people. The development of zero-energy or environmentally friendly structures is required to attain a sustainable future. Strategic design of the building’s envelopes in green energy buildings can reduce air conditioning expenses. This article focuses on several insulation-integrated fly ash brick wall envelopes that have been designed to reduce CO emissions, reduce air conditioning expenses, and figure out payback times in warm-temperate and hot-arid regions. The degree-hour technique for heating and cooling, as well as unsteady heat transfer characteristics, are taken into consideration in this research. This is achieved by incorporating thirteen innovative insulation materials into fly ash bricks in three distinct configurations, (i.e., insulation layer near to the outer end of the fly ash block, on the middle of the fly ash block, and near to the inside end of the fly ash block). Experimental measurements were carried out to determine the thermo-physical characteristics of insulation materials. The analytical findings are confirmed through experimental validation. In hot-arid and composite climatic zones, placing an insulation layer (cloth-40/foam-60) near the outer end of the fly ash block resulted in the highest savings on air-conditioning costs of 0.89 $/m and 0.90 $/m, respectively. They also achieved the highest carbon mitigation values at 17.2 and 16.8 kg/kWh. Insulation-integrated wall envelopes represent the pinnacle of energy efficiency in green building design, seamlessly combining advanced insulation materials with cutting-edge construction techniques to minimise energy consumption and maximise sustainability.

创新、隔热、集成：在创新隔热材料中采用循环经济，以减少粉煤灰砖建筑的空调费用和碳减排


全球建筑业对能源的需求急剧增加。这些能源的很大一部分用于满足建筑物的供暖、通风和空调需求，这对于维持人们的福祉至关重要。为了实现可持续的未来，需要开发零能源或环保结构。绿色能源建筑围护结构的战略设计可以减少空调费用。本文重点介绍几种集成隔热粉煤灰砖围护结构，这些围护结构旨在减少二氧化碳排放、减少空调费用，并计算出暖温带和炎热干旱地区的投资回收时间。本研究考虑了加热和冷却的度小时技术以及非稳态传热特性。这是通过将十三种创新隔热材料以三种不同的配置融入到粉煤灰砖中来实现的，（即，隔热层靠近粉煤灰块的外端、在粉煤灰块的中间、以及靠近粉煤灰块的内端）粉煤灰块）。进行实验测量以确定绝缘材料的热物理特性。分析结果通过实验验证得到证实。在炎热干旱和复合气候区，在飞灰块外端附近放置隔热层（布料 40/泡沫 60）可最大程度节省空调成本，分别为 0.89 美元/平方米和 0.90 美元/平方米分别为米。他们还实现了最高的碳减排值，分别为 17.2 和 16.8 千克/千瓦时。 保温一体化围护结构代表了绿色建筑设计中能源效率的巅峰，将先进的保温材料与尖端的施工技术无缝结合，以最大限度地减少能源消耗并最大限度地提高可持续性。
