The construction works must be designed, built and demolished in such a way that the use of natural resources is sustainable and in particular ensure the following:
(a) reuse or recyclability of the construction works, their materials and parts after demolition;
(b) durability of the construction works;
(c) use of environmentally compatible raw and secondary materials in the construction works.
The new seventh fundamental sustainability requirement has not been applicable to date, as no method to define the relevant technical requirements to be included in the harmonised standards had been defined. However, the requirement has now been adopted and will be applicable once the harmonised standards have been revised on the instruction of the European Commission.
As the drafting of new standards and the revision of standards already adopted have come to a standstill, the European Commission has announced that a revision of the Construction Products
Regulation and the harmonised standards already in place is needed. Until such revision has been completed, the harmonised standards currently in force will remain the basis of CE marking.
National legislation in the field of building and construction focuses on buildings in their entirety, whereas the Construction Products Regulation concerns individual construction products that can be placed on the market and subsequently used in buildings.
There may be national building regulations that set out special requirements for the use of a construction product for a specific purpose in a building or structure. Such regulations mean that the construction product in question may only be used to a limited extent in a member state.
