More than a third of global resource consumption
50% of energy consumption in EU
36% of CO2 emissions in EU
1/3 of all wastes in EU (C&D) in EU
Big share of existing public and private housings, dates from before 1975.
Poorly insulated housing lead to serious fuel overconsumption, especially among the most modest households.
Issue of sustainable renovation of housings is therefore a priority!
Energy-efficient house, embodied energy in the construction represents several years of heating in equivalent energy

At product level (or application level) EPD is difficult be used in a context of decision making and benchmarking (for communication)
• Definition of Functional Unit,• Benchmarking (define performance classes for
representative products),• Aggregation (aggregation of different modules,
normalization and weighting, reduce non-essential indicators, etc.).
At building level (B2B and B2C)• Mechanism to converge EPDs to the building
need to assessed and simplified, • Simplified tools are needed to mainstream
use of EPDs,• Missing tools for eco-design (marginal today).
Missing EPDs for companies with limited resources (ex. SMEs) is a discriminatory aspect.
Reduce costs of EPDs, Develop supporting PCRs, Financial support from public authorities.
Company X
Markets Belgium, France, Netherlands and Germany
For product Y (Same product for all these countries)
How many EPDs = 4
How many verifications = 4
How many times registration costs = 4
Estimated cost ~ +++ euros
1. In some countries if the national default database is not used the EPD is accepted but not usable in the framework of national schemes.
2. Scope of EPDs are different from country to country in EU
- Module arrangement are not the same.
- Module D is mandatory in Netherlands and optional in France.
- Module A to C is mandatory in France while several EPDs are cradle to gate with or without options for other countries.
