Energy savings with Solar Protection
Small investment –
great Savings potential
SOLAR SHADING PRODUCTS HELP TO REDUCE ENERGY CONSUMPTION
– THIS ARGUMENT IS OFTEN HEARD. BUT HOW MUCH CAN ACTUALLY BE SAVED?
LET US LOOK FOR ANSWERS.
What do solar shading products actually offer in terms of
energy balance? To this end, the European Solar Shading Organization
assumes, amongst other things, that 70 percent of the ener -
gy in Europe is spent on a building's heating requirements
and that 75 percent of all glazing is equipped with solar protection.
energy and CO2 savings of up to 19 percent are possible.
A DIRECT COMPARISON WITH
AND WITHOUT SOLAR PROTECTION
As a matter of fact, studies on specific energy savings provided

all the facts we know today on the subject. The study

square, two identical windows, facing east. While the dark
yellow shade of the blind on the left window gently darkens
the room, the right window gives an unobstructed view outside.
Appliances measure the temperatures for each section
of facade section – in the room and in front of the facade.
This is the experimental setup in the VERU research building.
The investigations on both of the two windows take place
under the same atmospheric conditions; the reference value
measured makes it possible to detect product advantages
Associations and manufacturers from the solar shading field
also resort to the possibility of having their products tested
under real conditions and on a real-life scale. This applies, for
example, to the influence of indoor solar shading systems on
a building's heating requirement during the winter months.
The german association ViS for internal solar shading analysed
this in 2009.
