DESCRIPTION
The Construction Product Regulation - CPR- (EU Regulation 305/2011) defines a Basic Requirements for Construction Works: the sustainable use of resources. Member States and the building sector seem to be are struggling with this Basic Requirement to works. IF Member States set requirements for this on works (buildings) and IF this results in demanding additional information on construction products then EN15978 and EN15804 are the appropriate tools for specifying the methodologies and indicators. The rules (especially the recitals) in the CPR show the way.

CPR – Recitel 1
• The rules of Member States require that construction works be
designed and executed so as not to endanger the safety of persons,
domestic animals or property nor damage the environment.
8
CPR – Recitel 2
• Those rules have a direct influence on the requirements of
construction products. Those requirements are consequently
reflected in national product standards, national technical approvals
and other national technical specifications and provisions related to
construction products. Due to their disparity, those requirements hinder
trade within the Union.
9
CPR – Recitel 3
• This Regulation should not affect the right of Member States to
specify the requirements they deem necessary to ensure the
protection of health, the environment and workers when using
construction products.
10
CPR – Recitel 12
• The methods used by the Member States in their requirements for
construction works, as well as other national rules relating to the
essential characteristics of construction products, should be in
accordance with harmonised technical specifications.
11

CPR & EPD - Recital 55
The basic requirement for construction works on sustainable use of
natural resources should notably take into account the recyclability of
construction works, their materials and parts after demolition, the
durability of construction works and the use of environmentally compatible
raw and secondary materials in construction works.
12
CPR - Recitel 57
• Wherever possible, uniform European methods should be laid down
for establishing compliance with the basic requirements set out in
Annex I.

• Building performance on “defined” parameters
• We need:
– Building scenarios
– Product information & scenarios that meet the building scenarios
– Process information & scenarios that meet the building scenarios
• The standards provide the methodology for quantification of the
performance
36
Construction products are intermediate products
37
• The end use product is the building (works)
Product performance is defined in the building
? one layer-two layer? climate indoor-outdoor? type of building? building life time? application? maintenance scenario? end-of-life scenario? ………

• CEN TC350 standards
– provide the methodologies for quantifying environmental performances
– offer a “basket” of environmental indicators
• If regulators want demonstration of compliance with BRCW 7,
– then define performance demands for buildings
– specify the resulting information demand for construction products
