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%.

NEXT-BUILDINGS

The NEXT-Buildings project focuses on low energy buildings also called active houses, which are not only buildings, but active components in the overall integrated energy systems. The target is to demonstrate affordable solutions for social housing and revitalisation of town areas. The solutions...

NEED4B

NEED4B is a collaborative project that will demonstrate cost-effective and energy efficient technologies and methods for the design and construction of very low-energy new buildings. A series of pilots located in different European climates will show how to achieve a primary energy consumption...

ZENN

The research project ZenN aims to reduce energy use in existing buildings and neighbourhoods. The project strives to: demonstrate the feasibility of innovative low energy renovation processes for buildings at the neighbourhood scale, identify, optimise and disseminate the most promising management...

GrowSmarter

GrowSmarter aims to stimulate city uptake of smart solutions by using the three Lighthouse cities Stockholm (Sweden), Cologne (Germany) and Barcelona (Spain) as a way to showcase 12 Smart City solutions: from advanced information and communication technology and better connected urban mobility, to...

E2REBUILD

E2ReBuild project investigated, promoted, and demonstrated cost-effective and advanced energy-efficient retrofit strategies that create added value for existing residential buildings and endorse end-users to stay and build a dynamic society. The vision of E2ReBuild was to transform the retrofitting...

IMPRESS Site Drobeta Turnu Severin

Decebal High School consists of two main buildings, the old one was constructed in 1897 and is classic design, and the new one was constructed in 1970 and is a modern building, in comparison. The new part of the building will be renovated. The new school has five storeys above ground and one below...

IMPRESS Site Naples

The test facade for the installation and preliminary testing of the retrofitting panels that will be developed during the research project is located at the Institute of Polymers, Composites and Biomaterials in Fuorigrotta (Naples, Italy). The building has a concrete frame with brick walls...

MORE-CONNECT Site Talinn

The demonstration site includes one building constructed with prefabricated concrete panel elements. It is a typical soviet apartment building, and it is part of a large housing estate. The key characteristics are: construction date: 1986 number of storeys: five net area: 3824 m2 heated area: 3306...

MORE-CONNECT Site Cesis

The MORE-CONNECT site in Cesis, Latvia is located in a rural area where the average heating season lasts for 208 days. The demonstration building is a typical soviet building, constructed from silicate bricks and widely built in suburban and remote areas. The total floor space is 559 m2. Due to the...

MORE-CONNECT Site Rijssen

The first pilot project within MORE-CONNECT in the Netherlands is situated in Rijssen, Adriaan van Ostadestraat, and is part of a building block that consists of five houses. The energy label of this house is F and the average monthly energy bill exceeds 185 euros per month plus fixed rates for...
