dc.titlePerformance assessment of building integrated spectrally selective radiative cooling systemen_US
dcterms.abstractThe building envelope separates the indoor and outdoor environments, including foundations, roofs, walls, doors and windows. The building envelope can be used as a thermal insulation layer, playing an important role in regulating the indoor temperature and determining the energy required to maintain a comfortable indoor temperature. Reducing the heat transfer of the shell can effectively reduce the indoor heat load and cooling load. There are many ways to reduce the heat transfer of the shell, such as green roofs, shading nets, solar panels, roof sprinkler systems, and cold roofs. At present, the roofs of Hong Kong mainly use shading equipment to reduce the radiation intensity of direct sunlight, thereby reducing the heat absorbed by the building and lowering the indoor temperature. The cold roof has high reflectivity and emissivity. It can reflect sunlight into the atmosphere and radiate absorbed solar energy, rather than conduct absorbed heat under the building. Traditional black roofs do not reflect sunlight and radiant heat like cold roofs. Heat is easily absorbed by the roof and penetrates into the building, increasing cooling costs. On the contrary, cold roofs can reduce cooling costs in the hot summer, thereby saving energy and reducing costs. This article will study the use of nanotechnology material coating to cover the cold roof instead of Hong Kong as the mainstream method of radiant cooling system, and use "EnergyPlus" to simulate and analyze it as a roof strategy to evaluate its feasibility and effectiveness.en_US
