Those who live in low-energy buildings are not experts. But energy professionals have been aware of the importance of meeting their needs, right from conception stage.

The construction of a building does not only start with its design by architects and engineers.

The overall building stock represents about 40% of the EU’s energy consumption. It also produces about 36% of its total CO2 emissions. Besides, new buildings only account for 1% to 1.

Ulrich Filippi Oberegger is a senior researcher in the energy management in buildings group of the Institute for Renewable Energy of EURAC Research . He tells youris.

The building sector has traditionally been fragmented. Many different actors are involved at different stages, from the design to the performance monitoring stage.

EnginSoft , is an Italian consultancy specialised in computer-aided-engineering. It has experience of contributing to the development of low energy buildings, under the EU-funded DIRECTION research project.

Achieving nearly zero energy consuming cities: this is the goal of three large scale district renovation projects. They are currently being tested in Valladolid, Spain, Genoa, Italy and Kartal - Istanbul, Turkey.

To make a building sustainable, taking into account its climatic conditions is key. No better examples than the three showcase buildings under the EU funded  DIRECTION project.

Sustainable buildings partly depend on control strategies to be energy efficient.

A new Directive, dubbed the energy performance of buildings Directive (EPBD), brings the new concept of net -zero energy buildings (NZEB) meaning buildings with a zero energy balance that have a better level of energy performance than the standard energy efficiency requirements in current building codes.
