More than 40% of the total Greek population (about 4.0 mil of the 10.0 mil total) live in Attica region. Most residents live in buildings constructed before 1990, with low energy performance factors such as high energy use levels, insufficient ventilation, uneven indoor temperatures, and insufficient thermal comfort levels. Therefore, a deep level of renovation is required.
Given the fact that most of the buildings are privately owned and located in urban areas, it is almost impossible (due to the excessive bureaucracy) and very expensive solution to reconstruct new buildings. A major renovation of the existing buildings would be the only practical, cost-effective and low-energy solution.
For demo 1
1) Installation of PV cells in the roof (size: 25-30m2)
2) Battery box for energy storage
3) Optimization and monitoring system for PV production per module
4) Installation of heat pump
5) Heating autonomy per room with thermostatic head per radiator
For demo 2
1) Installation of an integrated thermal insulation system (installed on the external walls)-10 cm (recyclable material).
2) Installation of an integrated thermal insulation system (on the roof), (60% recycled glass)
