The LCA is a method of multi-criteria environmental approachfor a product, a system or a process for all steps in the life cycle of the product (ISO 14040-44).
4 steps:
• Definition of the scope of the study
• Mapping of flows
• Evaluation of environmental impacts
• Interpretation of results

What is an « ecologically speaking » performant building?
EPD / EHDS+ Environmental performance of buildings
.
> A designed, built, used, debuilt building integrating the environmental dimension accordingto a multi-criteria and multi-step environmentalapproach.
.
> A building for which the result of the LCA is the best of scenario envisaged and/or the best comparing to a referencebuilding.

EPD / EHDS+Conclusions
.The EHDS:
> Are French standardized documents which representLCA results + sanitory informations on building products.
> Allow objectivizing environmental performance of products and their contribution to the environmentalperformance of buildings.
> Allow to find out the limit Eges PCE of the future regulation E+C-.

EPD / EHDS+Conclusions.The EHDS of VMZINC:
> Beginning of July 2017 -> 7 EHDS available on INIES
> They allow to objectivize and enhance:
The relevance of the reference lifespan of VMZINC rolled zinc (100 years)
Environmental advantages linked to the recyclingat the end of the lifespan (recycling rate of 98 %) The energy and carbon footprint relevance of
VMZINC rolled zinc in the field of metallic solutions used for envelop applications.
