The use of Brise Soleil or Sun Screens to reduce solar heat gain through glazed facades is now recognised as an important consideration in modern buildings. Countries situated in northern latitudes such as Ireland, must deal with the sun’s angle being lower, which results in more exposure through vertical glazing causing greater heat gains.
Functions
The elliptical design of the blades reduces the susceptibility of the Brise Soleil to wind load, allowing it to be used on high rise buildings and in all weather conditions. Both vertical and horizontal Brise Soleil provide highly effective shading in the summer with uninterrupted views, whilst minimising the effect on light transmission in the winter.
Most bespoke and traditional Brise Soleil or solar shading panels can be manufactured off-site, into modular or unitised forms, ensuring speedy installation. The system has an array of accessories allowing for cost effective project specific bespoke solar shading designs
to be incorporated into the facade.
When designing horizontal solar shading the length, width and projected dimensions of horizontal sunscreens will depend on a number of factors, one being the time of year. For south facing elevations in Ireland the highest sun angle occurs at midday during the month of June. The angle of the sun rises during the months of April and May peaking in June then declining through the remainder of the year.
