Energy Efficient Buildings
Public buildings account for a considerable share of the building stock in Europe and represent a target for renovation that is highly visible to the public. The A2PBEER project has put together a set of retrofit technologies that can be applied to public buildings across the spectrum of climates found within Europe, and is now beginning to demonstrate the effectiveness of these solutions through a set of real life demonstration sites

Retrofitting public buildings
Buildings consume about 40 per cent of total energy requirements in Europe. In the context of all end-use sectors, buildings represent the largest sector, followed by transport with 33 per cent. The existing
building stock, especially
buildings built before 1980, represents the biggest potential sector for energy savings. About 70 per cent of the total European building stock was constructed between 1945 and 1980, with little consideration of energy efficiency criteria due to the lack of prescriptions and lack of affordable
considerable share of the building stock and have high visibility in public life, so the public sector represents a potentially important driver for demonstrating the achievement of zero energy buildings and stimulating market transformation towards more sustainable passive and active solutions. Shifting to a more energy-efficient
economy should accelerate the development and spread of innovative technological solutions for buildings that achieve indoor comfort standards with low energy use, and

innovative active and passive technologies. In order to achieve the EU objective of
reducing greenhouse gas emissions by 80- 95 per cent by 2050 compared to 1990, the building sector needs to cut down its energy use. The rate of building renovation therefore needs to be increased. Buildings owned by public bodies account for a

boosting economic growth and creating high quality jobs in several sectors related with the construction value added chain. The A2PBEER project will demonstrate
that it is possible to meet current zero energy building requirements in existing
public buildings through affordable and adaptable retrofitting technologies. The deployment and use of innovative façade/ lighting/heating and cooling refurbishment systems and a systemic approach can help achieve this goal with an approximate payback periods of seven years.
Building envelopes The project uses a number of technologies to implement energy savings. Vacuum Insulation Panels (VIPs) have been shown to provide better insulation performance than conventional insulation materials, so installations in the external and internal facades are being investigated. VIPs are commercially available on the market, and when considering a high thermal resistance façade system they represent one of the most cost-effective solutions to maximise energy savings.
Smart windows The main issue of existing low emissivity (low-e) windows, which are designed to decrease the amount of heat lost through windows, is that the coating is either placed on the outer side (maximum solar gain, desirable in winter) or the inner side (minimum solar gain, desirable in summer) of the glazed unit. But if a smart reversible
