NEED4B will develop a new replicable methodological approach for designing, constructing and operating very low energy new buildings. This methodology will be validated and enriched by the experience gathered in a series of demonstration buildings to be constructed in 5 European countries. These buildings will proof the feasibility of constructing buildings with an energy consumption target lower that 60 kWh/m2 year.

The variety of typologies and uses of the buildings as well as their location in different climatic zones, contributes to the results of the project being so broadly applicable across Europe:

The 5 demonstrators will gather the following characteristics.

• 2.068 m2 in Mons, Belgium: several type of residential and tertiary buildings.
• 5.214 m2 in Lecce, Italy: a mixed tertiary building.
• 2.712 m2 in Zaragoza, Spain: Offices and R+D laboratories.
• 314 m2 in Borås and Varberg, Sweden: industrialised single residential houses.
• 17.576 m2 in Istanbul, Turkey: Faculty building in a University campus.

It is expected that the measures to be undertaken in the buildings will reduce CO2 emissions by 94% compared to a standard building and will have an impact on the energy bill which could be reduced in 9,6 €/m2•year.

NEED4B expects to contribute also to the standards, regulations and policies related to energy efficiency in buildings at different levels, on the basis on the experience gained by means of the demonstration activities.

The project will also deliver recommendations and guidelines adapted to different types of stakeholders: investors, promoters, owner, users, architects, contractors, public authorities, standardization bodies, policy makers, SMEs, etc. By means of these project outputs, these actors will be able to adopt the developed and demonstrated innovative, cost effective and high performance techniques, concepts and solutions, contributing to boost construction of high quality new energy efficient buildings
