Solar and visible optical properties of glazing systems with venetian blinds: Numerical, experimental and blind control study

摘要: Abstract The increasing use of glazed areas in the building envelope can lead to high solar gains and glare problems that strongly impact entire energy consumption, peak loads indoor comfort. An important fundamental strategy sustainable design for controlling heat daylighting through fenestration is shading devices. Therefore, it recommended detailed models accurately estimate optical properties different types devices (such as roller blinds venetian blinds) include their effects glazing system analysis. This paper describes a net radiation method determining both visible with devices, particularly blinds. Some numerical results were compared situ experimental measurements carried out an outdoor test cell. work included measurement illuminance irradiance fluxes determination transmission system. agreement between predictions was better overcast than clear sky conditions. Moreover, blind control blocks direct radiation, whilst enabling diffuse indoors, implemented.
