Simulating annual autoregulation of daylight by grating smart window with angular-selective transmission
As a basis for further development of the BPS computer software, a method for simulating the characteristics of buildings with grating smart windows is proposed. This novel smart technology provides annual autoregulation of light and solar transmission due to an optical filter with two thin-film gratings located on window surfaces to adapt to the Sun’s trajectory and achieve angular-selective transmission. The previously developed methods for calculating the filter parameters are modified and on their basis new equations for the BPS software are obtained, which differ from the existing ones, unsuitable for grating smart windows due to their distinctive properties. The fundamentals of BPS for a building with such smart windows are considered in detail in order to select the individual parameters of grating windows for all rooms where they are needed. Calculation methods are validated by numerical simulation of the transmittance, sDA, ASE, DGP and by illuminance measurements.
