A light weave fabric with appropriate visible light transmittance and low absorptance is recommended to allow more sunlight into the classroom, while reducing cooling loads.
Daylighting and Thermal Assessment of Combined Dynamic Shading Systems on Energy Consumption in Educational Buildings
In a standard one-inch insulating glass unit with a clear inboard light, Vistacool Caribia produces Visible Light Transmittance (VLT) of 47%--nearly twice the average of other tinted, reflective-coated glass products on the market--together with a Solar Heat Gain Coefficient (SHGC) of 0.34.
Specialty coatings: from cool optical effect coatings for automotives to energy savings coatings for the home, these specialty coatings are not your average can of paint
Low-E coatings can combine the advantages of a reduced U-factor and SHGC while maintaining high levels of visible light transmittance. These microscopically thin layers of metal or metallic oxide can be designed to filter radiation so as to reflect UV and infrared radiation while transmitting visible wavelengths.
