EPD / EHDS+Definitions

International or Europeanstandardized Document for presentation:

• Of results of a product life cycle analysis.

The International standards are ISO 14025 type III or EN 15804.

> Environmental and Health Declarations – EHDS

French standardized document of presentation:

• Of results of Life cycle analysis on building product.

• Sanitory information on the concernedbuilding product.

Obligatory critical review from July, 1st 2017!

EPD / EHDS+Definitions

In compliance with NF EN 15804+A1 and National complement (NF 15804/CN)

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

EPD / EHDS+Definitions

> Life Cycle Analysis – LCA

Incoming flow(raw material, water,

energy)

Outcoming flow(Emissions, waste)

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.

BEPOS balance =

Primary Energy Consumption* –Exported energy quantity

* Non renewable / Non recoverable

Scope of the calculation: Energy for all uses(Uses RT + other uses)

Unit: Kwhep/m2.year

EPD / EHDS+BEPOS Balance – Objective

Input of fossil

energiesInput of

renewableenergies

A « carbon » level based on:

• Eges* : Indication of greenhouse gasesemissions on the entire life cycle of the building

• Eges PCE** : Indication of greenhouse gasesemissions of building products and usedequipments.

EPD / EHDS+Greenhouse gases emissions - Eges

* Eges = Greenhouse gases emissions** PCE = Building Products and Equipments

Indication of « Climate change » on EHDS!
