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.
Comparison of Methods for Modelling Complex External Shading
This paper aims to assist with the choice of these methods by applying each to a simplified energy model containing a complex shading device and comparing the total solar energy transmittance
Experimental and numerical determination of the total solar energy
In response to the increased occurrence of overheating problems in glazed buildings in recent years, EMPA has focussed on the determination and modelling of the total solar energy
Definitions of Key Terms
% Solar Transmittance (T-sol): The ratio of the amount of total solar energy in the full solar wavelength range (300-2,500 nanometers) that is allowed to pass directly through a glazing system (e.g., a
Building physics & sustainability | WAREMA ARCHITECTs
Total solar energy transmittance of the sun shading system and glazing combined. This value is normally calculated using the simplified DIN EN 13363-1/ DIN EN ISO 52022-1 method or the
Solar transmittance analysis of different types of sunshades in the
This paper simulation, presents the findings of a comparative study for evaluating the effects of different solar shading devices on the solar transmittance properties of windows with different orientations in
GUIDANCE NOTE S 7A
This guidance note investigates g-value and gtot as these provide key energy performance figures for assessing the amount of solar energy transmitted into a building.
Total solar energy transmittance (g-value) (Noël 2004)
Therefore, this research proposed an integrated simulation-based workflow using EnergyPlus and Python-based package, OpyPlus, to adjust a roller shade for single occupied office space in a hot...
Performance value terms
Solar Factor or Total Solar Energy Transmittance or g-value (g%) is the total solar radiation transmitted by the glass. Shading Coefficient (sc) is Solar Factor divided by 0.87.
Solar protection
Inputs for this calculation are solar integrated optical and thermal parameters of glazing and shading. The calculation procedure is straightforward and can easily be performed in a spreadsheet.
