Tents/Sunshades

The use of shading systems in buildings is necessary when sunlight levels in the region are high. Given the fact that Greece has a very high percentage of sunshine during the entire time it is easily understood that the use of shading is mandatory.

It is reported that the lowest annual sunshine rate is a little less than 2.200 hours per year in Epirus, W. Macedonia and Rhodopes, while the highest price is about 3.100 hours per year and occurs in Rhodes and Ierapetra.

The external shading reduces solar radiation before it reaches the surface of the windows. Placing external shading prevents direct solar radiation to enter the house by reflecting it to the environment. The diffuse solar radiation is only transferred to the interior of the house and that helps in reducing the incoming heat, which results in lower energy consumption for cooling.
