Within a district or eco-neighborhood, Third Industrial Revolution buildings will be energy selfsufficient
through efficient energy use and the generation of energy on-site, mainly by
photovoltaic. Due to electrical storage capacities, buildings will stabilize the electrical grid. The
Working Group expects that the use of electricity in buildings will also increase in the heating
sector and that geothermal will be used in every district.
Buildings will be intelligent by using building information and modelling (BIM) technologies on
the entire chain from design, construction and operation up to disassembly and re-use of
elements and materials. This contributes to the aim of total circularity, where no waste is
generated in the construction sector, since only circular and re-usable materials are used.
Luxembourg is also emphasizing the need to ensure a high quality of life in the future by
ensuring that buildings assist in providing a healthy and sound environment for the occupants.
The Working Group emphasizes that quality of life depends, at least in part, on the construction
material. A good building design also requires abundant daylight and adequate sun protection.
