Composite materials for renovation of roofs in existing buildings

The EPBD directive (91/2002/EU) paved the way for the European Union member states to develop and apply a holistic approach on the building’s energy performance. It is documented that buildings’ energy consumption represents 40% of the total energy consumption in Europe, a significant figure when compared to the industry and transportation sector. Respectively the CO2 emissions are calculated to be around 30%.  A series of published data indicates that the uninsulated or poorly insulated roofs account for up to 25% of energy losses.
