Building is one of the most environmentally unfriendly human activities.
Buildings require large amounts of materials and moreover they use scarce space.
Measures are being taken to limit the environmental load of buildings. The Netherlands is leading together with other Western countries. She has her measures captured under the denominator 'Durable Building'. An unfortunate name, certainly for the very pragmatic package of measures. The outcome of the calculation, in which, among others, the degree of insulation, the orientation, the typology and the efficiency of the installations are introduced, gives an indication about the future use of energy of a building.
