Energy efficiency in buildings

Buildings are responsible for 40% of energy consumption and 36% of CO2 emissions in the EU. While new buildings generally need less than three to five litres of heating oil per square meter per year, older buildings consume about 25 litres on average. Some buildings even require up to 60 litres.

Currently, about 35% of the EU's buildings are over 50 years old. By improving the energy efficiency of buildings, we could reduce total EU energy consumption by 5% to 6% and lower CO2 emissions by about 5%.

EU-GUGLE

The EU-GUGLE project aims to demonstrate the feasibility of nearly-zero energy building renovation models in view of triggering large-scale, Europe-wide replication in smart cities and communities by 2020.  To reach this objective, the eight pilot cities will join efforts to combine the latest...

EE-HIGHRISE

The overall objective of the EE-HIGHRISE project was to demonstrate and validate new technologies, concepts, and systems used, in order to test and assess the technological and economic feasibility of innovative energy solutions in the high rise demo buildings in contributing to the EU energy and...

DIRECTION

DIRECTION aimed at demonstrating how the use of very innovative and cost-effective energy efficiency technologies can lead to the achievement of very low energy new buildings. This aim along with the effective adoption of low energy buildings was achieved by switching to a model whereby energy...

CITyFiED

The CITyFiED project aims to develop a replicable, systemic and integrated strategy to adapt European cities and urban ecosystems into the smart city of the future, focusing on reducing the energy demand and GHG emissions and increasing the use of renewable energy sources by developing and...

CITY-ZEN

CITY-ZEN aims to develop and demonstrate zero energy cities with a central role for citizens. The team of the project works together to achieve a future-proof grid, innovative heat and cold solutions and energy efficient buildings.
