NO development of new methods!

There are well working systems operational based on CEN TC350 standards

54

actual discussion 2014:

what environmental indicators are suitable to answer BWRC#7 ?what mandatory declarations for construction products would result from it?

55

EXTRACTfrom

SEE MOREon linking BWR7 to environmental indicators:

56

BWR #7

The construction works must be designed, built and demolished in such a way that the use of natural resources is sustainable and ensure the following:

• (a) 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.

“environmentally compatible” allows a rather wide interpetation:• no adverse effects on other environmental goals

this could imply the necessity to list the performance on all environmental indicators

However:

European and/or National regulatory demands will select and specify what indicators are to be assigned as Essential Product Characteristics

66

• specify a harmonised information demand for construction products• assign the methodologies and standards to quantify the performance

• uniform standards for quantication are ready to be used: EN15804 – EN15978

• the European Commission is about to mandate the inclusion of environmental product characteristics in the harmonised product standards

67

EU-wide



• Member States / Regions :• assign the rating tool to be used• assign weighting, benchmarks, rating factors• set performance levels

74

• No need for further development of methodologies

• 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

BRCW 7 : SUSTAINABLE USE OF NATURAL RESOURCES

however, notify and harmonise the demand for the information on EU-level !

75

summarising

76

summarising - sustainability standards

• CEN TC350 standards provide– a uniform methodology for quantifying the environmental, social

and economic sustainability performance.– harmonised indicators for quantifying the sustainability performance– for construction products and for buildings (and civil engineering works)

and .......– the standards do not qualify the results, no ranking nor

benchmarking

77

summarising – rating tools• rating tools

– more and more the rating tools implement and apply the standard EN15978 for quantifying the environmental performance of buildings

– are supplied with environmental product declarations (EPD) acc. EN15804

• EN15804 and EN15978 are consistent and fully aligned and provide non-aggregated information in information modules

– this, as sustainability it self is not uniform, allows • applying different (national customised) weighting factors and ratings per indicator• enables providing full transparency in 14 information modules over the lifecyle

stages• enables tracing back on impacts of products and processes.

78

summarising - regulators• regulators

– specify the performance demands for works (buildings and civil engineering works)

– base this performance demands for works on the 7 Basic Requirements for Costruction Works (BRCW) as defined in the EC’s Construction Products Regulation – CPR 305/2011

– notify a consequent demand for (environmental) declarations on construction products on EU-level define the essential environmental product characteristic(s)

– assign a methodology for quantifying, rating or benchmarking the (environmental) building performance
