The construction and building industry in the modern world heavily relies on advanced techniques and materials such as polymers. However, with the world's population alarmingly increasing, contributing to the greenhouse effect, and severe weather conditions amplifying, it has become crucial to reduce the heat effects in both new and old buildings. To achieve this, 50-70% more energy is necessary, which highlights the importance of energy-efficient construction practices and materials. Consequently, a comprehensive study was conducted to evaluate the efficacy of Polyurethane in indoor environments and energy conservation. Current study was performed due to an innovative application of insulation materials as to reduce the heat and energy costs in construction works. Thermal conductivity at mean temperature 35 °C was found 0.0272 (W/m K) with maximum in burnt clay brick (1.43 W/m K) by using hotplate apparatus. Specific heat was also found less 0.85 (KJ/Kg K) at density 32 kg/m while results were at par in reinforcement cement concrete and burnt clay brick 0.91, 0.91 (KJ/Kg K) respectively. Similarly, heat transmittance values of different roof sections by using polyurethane insulation showing satisfaction the ECBC in Buildings deviating standard U-value 1.20% to 0.418 (W/m K) with its excellent performance. Polyurethane treatments have been found to exert a significant impact on the computation of thermal resistance and overall heat transfer coefficients. In contrast, non-insulated treatments yielded inconclusive results with little to no significance. This highlights the importance of insulation materials in energy-efficient construction practices. Energy consumption in winter and summer also has shown the significant impact by using polyurethane application with cumulative saving of 60-62% electricity. Economic Benefit of polyurethane in RCC and Conventional buildings describes positive and highly significant impact in present study. Application of polyurethane in new and old buildings ultimate enhanced the better quality of life and living standards from people of applied countries and is strongly recommended for future prospects and endeavors as Eco-friendly and energy efficient for sustainable development.
现代世界的建筑行业严重依赖聚合物等先进技术和材料。然而，随着世界人口惊人地增长，导致温室效应加剧，恶劣天气条件增多，减少新旧建筑的热效应变得至关重要。为此，需要多50%-70%的能源，这凸显了节能建筑实践和材料的重要性。因此，开展了一项综合研究，以评估聚氨酯在室内环境和节能方面的功效。当前的研究是由于隔热材料的创新应用，以降低建筑工程中的热量和能源成本。使用热板装置发现，在平均温度35°C时，热导率为0.0272（W/m·K），而烧黏土砖的热导率最大（1.43W/m·K）。在密度为32kg/m时，比热也较低，为0.85（kJ/kg·K），而钢筋水泥混凝土和烧黏土砖的比热分别为0.91、0.91（kJ/kg·K）。同样，使用聚氨酯隔热的不同屋顶部分的传热系数值令人满意，符合建筑中的ECBC标准，偏离标准U值1.20%至0.418（W/m·K），性能优异。已发现聚氨酯处理对热阻和总传热系数的计算有显著影响。相比之下，非隔热处理产生的结果不确定，几乎没有意义。这凸显了隔热材料在节能建筑实践中的重要性。冬季和夏季的能源消耗也显示出使用聚氨酯的显著影响，累计节电60%-62%。聚氨酯在钢筋混凝土建筑和传统建筑中的经济效益在本研究中描述为具有积极且高度显著的影响。聚氨酯在新旧建筑中的应用最终提高了应用国家人们的生活质量和生活水平，强烈建议将其作为生态友好和节能的可持续发展未来前景和努力方向。
