RESEARCH PROGRESS AND DEVELOPMENT TREND OF AIR-SPACED INSULATION ROOF
The thermal performance improvement of roof is of great significance for reducing indoor air conditioning and heating energy consumption,and improving indoor thermal comfort.The latest research progress and development trend of air-spaced insulation roof technology for building energy efficiency is introduced in this paper,and the thermal insulation principle of different air-spaced insulation roof technologies and their influence on indoor thermal comfort are analyzed.The research progress of the traditional construction and the innovative air-spaced insulation roofs are described respectively,the traditional air-spaced insulation roofs have the advantage of improving thermal insulation,but their structure has not maximized the advantage.In order to further improve the thermal performance,based on existing research works,many researchers have extensively studied on various new types of air-spaced insulation roofs through various measures,such as structural optimization,the use of new materials,composite roof etc.In addition,the research on the photovoltaic air-spaced insulation roof which combines photovoltaic with air-spaced insulation is discussed and compared,the photovoltaic air-spaced insulation roof has two advantages:Improving roof thermal insulation performance and using solar energy to supply power for buildings.Under the background that China advocates green development and accelerates the energy structure transition,the new air-spaced insulation roof conforms to the development trend of building energy efficiency and building-integrated photovoltaic(BIPV).
