Study on Exterior Insulation System of New Composite Insulation Board

The foam concrete used as surface materials and polyurethane used as core material for the development of new composite heat-insulated board of exterior insulation system. The research and applications showed that the thermal insulation system with excellent constructability, significant environmental benefits, economic and social benefits have been obtained. The implementation of 65% energy saving for residential buildings is the key of further work of energy efficiency in hot summer and cold winter zone, with huge market potential and the good application prospect.

Different Types

Along with the rapid urbanization and economic growth of China over the past decades, the thermal comfort needs of the people in this region have risen dramatically, and at the same time, promoting building energy efficiency is cited as part of the major projects in the 14th five-year plan for energy efficiency improvement. In addition, the outbreak of the COVID-19 epidemic has plunged people into long-term panic, and promoted the entire construction industry to think about a healthier and more sustainable living environment. To respond to the imbalance between energy supply and demand, an optimization analysis based on energy use is developed, assessing the energy efficiency of the window-to-wall ratio (WWR) design and calculating the energy consumption of three different types of residential buildings for both cooling and heating loads as well as for year-round loads. Owing to its harsh climate and huge energy consumption, in this study, the Hot-summer and Cold-winter (HSCW) zone of China was chosen as the experimental setting for the optimization analysis of WWR. Then, in the three main types of residential buildings, including detached houses, multi-story dwellings and high-rise dwellings, a correlation between WWRS and energy consumption in the cooling season, heating season and year-round was built. The comparisons between the WWRS and energy consumption for different types of residential buildings are presented. The design optimization recommendation for WWRS are proposed. It has significant positive meanings for the development of green and sustainably designed residential buildings that offer high levels of thermal comfort and energy efficiency.

Energy Consumption Calculation

With the further promotion to the energy conservation of buildings, the standard of 65 percent energy efficiency is gradually popularized. Because of some existing problems in external insulation Technology, such as security, durability and seepage, Self-insulation technique has been more and more concerned. In this paper, a kind of external insulation scheme and three kinds of Self-insulation schemes are designed for a typical residential building in Wuxi region. These schemes are simulated for energy consumption calculation and Economic Analysis by BECS software. The results show that self-insulation schemes not only meet the standard of 65 Percent Energy Efficiency, but also have more economic benefits than external insulation schemes.
