ABSTRACT

Against the backdrop of continuous growth in energy consumption and increasing environmental pressure, improving building energy efficiency has become an important issue that people have to face. The building envelope plays a crucial role in this. Although traditional building materials have superior structural performance, they have significant deficiencies in heat conduction and sound insulation. To solve this problem, this study compared the differences in energy efficiency, heat conduction performance, economy and sound insulation performance between traditional concrete, thermal insulation foam materials and nano thermal insulation materials. Among them, nano thermal insulation materials had the best performance in improving energy efficiency, with an increase rate of 48.7%. In the thermal conductivity performance test, the thermal conductivity of nano insulation materials was the lowest, with an average of 0.01 W/m•K. The cost-benefit ratio of nano thermal insulation materials in economic analysis was 0.2. In the final 24-hour sound insulation performance test, the average STC value of the nano insulation material was 65, indicating the most stable performance. From the specific experimental values, it can be seen that nano thermal insulation materials have significant advantages in improving building energy efficiency and improving sound insulation performance.
