Sustainable development benchmark developed by the USA and used in numerous countries

The LEED method

The LEED method

This sustainable building programme aims to recognize and highlight buildings that consume the lowest quantity of energy and that are most respectful of the environment. It can lead to 4 levels of certification: 

  • Certified: 40 points
  • Silver: 50 points
  • Gold: 60 points
  • Platinum: 80 points.

It is organized in 8 categories of criteria.

VMZINC and the LEED® system

Sustainable, recyclable, featuring significant levels of recycled materials, Environmental Product Declarations, etc., VMZINC systems offer many advantages that enable them to contribute to obtaining LEED® certification for the building in which they are used.

Used for building envelope applications or, more rarely, as an interior solution, VMZINC solutions mainly contribute to 4 LEED® categories of criteria:

LEED® V.4 criteriaVMZINC advantagesAccessible point
Ecological site management (SS)Extent of SRI possibilities according to designers' requirements (Azengar SRI > 35)2
Materials and RessourcesVMZINC's ambitious sustainable development commitment and policy1
 High levels of “pre-consumer” and “post-consumer” recycled content (33% and 21% respectively)1
 Numerous Enviromental Product Declarations compliant with ISO 14025 type III and EN 158041
 Health and Safety Data Sheets1
 Very little zinc scrap during installation (< 5%), which is 100% recyclable2
Energy and AtmosphereCompatibility of VMZINC systems with the most effective insulation systems (performance, thickness)*
 Surface thermal bridges minimized in VMZINC systems*
 PV system easy to integrate when used with VMZINC systems4
Quality of indoor environmentsAFSSET COV/Formaldehyde protocol on the main surface aspects concerned3
 A+ COV/ Formaldehyde classification(Decree of 23 March 2011 on labelling of food products)3

*VMZINC solutions contribute to the thermal performance of the envelope but are not sufficient on their own to obtain a number of points.
