a combination of ventilation and solar shading reduces the cooling load by up to 63 %?
Why use solar shading?
The need for solar shading
In order to cut undesirable energy losses as far as possible, airtight construction and thorough insulation are a sound choice. The heat demand falls but the need for cooling in a building increases. During the warmer (summer) months in particular, indoor temperatures can soar.
Moreover, our cityscapes now reveal more and more façades built using large areas of glazing. If the sun is left to its own devices, that can have a pretty negative effect on thermal comfort in the building. And on top of that: good airtightness and insulation mean it’s hard for the heat to escape, so that the energy costs for cooling the various rooms can mount up.
Ventilation and solar shading for the win
In order to avoid an unpleasant indoor climate the choice of a solar shading and ventilation system is entirely justified. Jointly, they can bring about a reduction in the cooling load of up to 63 %. (TNO, 2017) An effective outdoor solar shading system has a crucial role to play in the story. After all, it can lower the average temperature up to 12 %. (TNO, 2017) In addition, there is also an effect on the energy bill with a reduction of up to five points in the energy performance rating. (Bouw-Energie, 2018) An energy performance rating is synonymous with a more energy-efficient house and, therefore, signifies added value for the home.
Solutions for controlling and managing the sun
The choice of solar shading depends on your budget, the technical possibilities and … your own taste.
You can go for exclusively canvass solar shading/awning. But also a combination of ventilation and fabric solar shading in one and the same product is possible. Because the installer fits two systems in one product, this can save time and work.
For an architectural solar shading system there is an abundance of choice. There are systems with fixed and adjustable louvre blades, discreet and striking designs, and horizontal and vertical lines. Not only do the architectural variants give the façade a unique touch thanks to the sleek, rectilinear design. As well as retaining daylight, such solar shading systems ensure naturally and energy-efficiently that the sun’s rays do not get a chance to heat up the interior directly.
