2 ENERGY UPGRADE & ENERGY SAVINGS Buildings consume large amounts of energy for their heating and cooling. A large amount of the consumed energy is, in fact, wasted, since the elements of many buildings’ structures, are without any or with insufficient insulation, resulting to uncontrolled energy loss. Therefore, saving energy is, nowadays a demand, not only in Europe but globally as well, as it contributes to the protection of the environment and leads to a significant reduction of the heating/cooling expenses. Energy loss in building structures 35 - 40% energy loss through the roof (sloped or horizontal) 12-14% energy loss through the floor Depicted below are the energy loss points in a residence, without thermal insulation 20-30% energy loss through the windows 18-25% energy loss through the walls
