4 cases, 1 solution:

Avoiding

expensive

Energy by using

Solar energy

Summer Winter

Day We have to keep out the solar energy: We need solar shading

We collect the solar energy; well-being by internal glare-shields

Night We control visual contact with the outside by internal or external shadings

We reduce energy-losts by internal and extarnal shadings

Smart Solar Shading
