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%.

List of projects where this technology is being implemented.

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.
List of demo sites where this technology is being implemented.

EU-GUGLE Site Vienna

The EU-GUGLE demonstration district in Vienna is named Penzing or the 14th district. The smart Viennese gate to western Austria and to the Natura 2000 area, the Biosphärenpark Wienerwald, covers about 3,374 hectares with a share of 60% on open space including parts of the forest surrounding Vienna...

R2CITIES Site Genoa

The social housing district of Lavatrici was developed during 1980-1990. The pilot is located on the west part of the city in the so called Pegli 3 District on a natural hill. The site consists of more than 500 dwellings. It is divided in four main blocks and each of them is composed by three...

R2CITIES Site Istanbul

The selected pilot site is located at Yakacik district of Kartal, Istanbul. The use of low efficiency lighting systems and appliances and a slim insulation means very high energy consumption for Yakacık and therefore a high potential for improving. The demonstration site aims to retrofit a...

R2CITIES Site Valladolid

A complete retrofitting based on façade improvements, ICTs and renewable energy systems will be implemented in the Cuatro de Marzo district, the demo site chosen for the R2CITIES project in Valladolid (Spain). The district Cuatro de Marzo is located in the south part of the Valladolid urban area....

ZENN Site Grenoble

The neighborhood of Arlequin in Grenoble is a 1970s residential development of 1800 dwellings in a high-rise complex within a larger district called Villeneuve. The buildings range from 6 to 15 storeys and have a concrete structure with two kinds of façades: light pre-fabricated concrete modules...
