In recent years, energy savings in built-up areas have
focused on reducing consumption during use (heating,
lighting and so on). Less attention has been given to
energy consumption in the construction process and in
the manufacture of building materials. Now, more and
more new buildings are almost energy neutral or even,
on balance, generate energy. In this study, we focus wherever possible on the
circularity of the building materials used in the building
and less on the consumption of energy during the use of
the building
