14% Light Reflection Outside Available Glass Thickness
Solar Reflection is the proportion of solar radiation reflected back into the atmosphere. Solar Absorption is the proportion of the energy absorbed and re-emited by the glazing to the interior space.
Measuring Solar Transmittance and Solar Reflectance, Part 2
This software supports the calculation of visible light transmittance, UV transmittance, solar transmittance, and solar reflectance for flat glass according to JIS R3106.
Solar Transmittance
Solar transmittance, also referred to as light transmittance or visible transmittance, is the measurement of visible light passing through a piece of glass. Solar transmittance can be altered by the addition of

Electromagnetic radiation influences the transmittance of a glass depending on glass type and the wavelength of radiation. The influence of visible and UV radiation (less than 380 nm wavelength) on
Performance value terms
Solar Energy Direct Transmittance (Te, %) is the percentage of incident solar energy in the wavelength range of 300 nm to 2500 nm that is directly transmitted by the glass.
Methods of measurements
Method of measurement The insulating glass unit (or individual glass panes) mounted on a revolving support is irradiated by a light source. The transmitted or reflected light enters a collimator and the
Window Calculation Module: Engineering Reference — EnergyPlus 8.8
The solar radiation transmitted by a system of glass layers and the solar radiation absorbed in each layer depends on the solar transmittance, reflectance and absorptance properties of the individual
Performance GUIDE
Selecting glass for a project is an important and sometimes dificult task, to assist in this process G.James ofers the following recommendation for viewing glass samples.
Solar Transmittance/Solar Reflectance Measurement
Calculation of the visible transmittance, visible reflectance, solar transmittance, and solar reflectance was conducted using the solar transmittance measurement software shown in Fig. 5 to easily obtain
