This measure models two states of the electrochromic window, the light and dark states. This measure implements the electrochromic window as a three-layer construction, which includes a typical 3mm glass layer, an air gap, and an electrochromic layer. The control strategies are implemented via WindowShadingControl object. For the electrochromic window layer performance, the user could either use default values, which we got from View manufacturer data, or enter their own product performance. thickness_electro_glass Thickness of the electrochromic glass layer in mm Double m true false 0.0058 thickness_air_gap Thickness of the air gap between electrochromic glass layer and inside clear glass layer in meter Double m true false 0.0125 thickness_clear_glass Thickness of the inside clear glass layer in meter Double m true false 0.003 tc_electro_glass Thermal conductivity of the electrochromic glass layer in W/m.K Double W/m.K true false 0.9 solar_trans_light Electrochromic glass solar transmittance - light state Double true false 0.444 solar_ref_f_light Electrochromic glass solar reflectance - front side - light state Double true false 0.134 solar_ref_b_light Electrochromic glass solar reflectance - back side - light state Double true false 0.196 vis_trans_light Electrochromic glass visible transmittance - light state Double true false 0.696 vis_ref_f_light Electrochromic glass visible reflectance - front side - light state Double true false 0.119 vis_ref_b_light Electrochromic glass visible reflectance - back side - light state Double true false 0.133 ir_trans_light Electrochromic glass infrared transmittance - light state Double true false 0 ir_emis_f_light Electrochromic glass infrared emissivity - front side - light state Double true false 0.84 ir_emis_b_light Electrochromic glass infrared emissivity - back side - light state Double true false 0.159 solar_trans_dark Electrochromic glass solar transmittance - dark state Double true false 0.006 solar_ref_f_dark Electrochromic glass solar reflectance - front side - dark state Double true false 0.121 solar_ref_b_dark Electrochromic glass solar reflectance - back side - dark state Double true false 0.194 vis_trans_dark Electrochromic glass visible transmittance - dark state Double true false 0.012 vis_ref_f_dark Electrochromic glass visible reflectance - front side - dark state Double true false 0.098 vis_ref_b_dark Electrochromic glass visible reflectance - back side - dark state Double true false 0.114 ir_trans_dark Electrochromic glass infrared transmittance - dark state Double true false 0 ir_emis_f_dark Electrochromic glass infrared emissivity - front side - dark state Double true false 0.84 ir_emis_b_dark Electrochromic glass infrared emissivity - back side - dark state Double true false 0.16 gas_type Select the type of air gap for the electrochromic window Choice true false Air Air Air Argon Argon Krypton Krypton Xenon Xenon ctrl_type Select control strategy for electrochromic window Setpoint of glare, radiation, or illuminance should also be set based on selected control strategy Choice true false OnIfHighGlare OnIfHighGlare OnIfHighGlare OnIfHighSolarOnWindow OnIfHighSolarOnWindow MeetDaylightIlluminanceSetpoint MeetDaylightIlluminanceSetpoint glare_stp Maximum allowable discomfort glare index Electrochromic window will turn to dark state when glare index is above this value.
