Glass, frit and shading devices selection
Essential part of our services is to provide solutions that ensure adequate solar control (minimizing the cooling loads), while allowing for transparency and increased views. Essential to this service is a deep understanding of the potentials and limitations of the solar control mechanisms.
Protecting the building from excessive solar gains is crucial to avoid overheating during the cooling season, while providing adequate thermal and visual comfort levels for the occupants.
The main ways to reduce the transmitted solar radiation through glazing are:
Solar Control Glass: shading effect does not vary during the year; the reduction of solar transmittance results in reduction of daylight transmittance unless selective coatings are used.
Shading devices: variable effect depending on whether shading is angle dependent, movable or angle independent. It is an effective way of shading, but can significantly affect the view to the outside (when applied too often).
Frit: permanent effect, allows some view to the outside (depending on the frit density) and impacts on the building's appearance.
Different shading options can significantly impact on solar performance. Early solar exposure assessments can allow us to inform design by providing effective shading options and low cooling energy use.
