Green Building Standards

Green Building Standards

ASI aims to harmonise with relevant external Standards and Schemes wherever possible and appropriate, in order to enhance collaboration, reduce unnecessary duplication, and inform ASI’s learning and continual improvement.

The ASI Standards Benchmarking and Harmonisation Procedure describes the identification, benchmarking and review of external Standards and Schemes for potential harmonisation with, including recognition by and of, ASI Standards.

Green building standards, certifications and ratings systems have emerged since the 1990s and are aimed at mitigating the impacts of buildings on the natural environment through sustainable design.

ASI is working to achieve recognition of the ASI Certification program by selected green building initiatives. Below is a list of the green building standards that have recognised ASI Certification to date.

1) BREEAM (Building Research Establishment’s Environmental Assessment Method)

BREEAM is an international scheme that provides independent third party certification of the assessment of the sustainability performance of individual buildings, communities and infrastructure projects.

BREEAM third-party certification involves the checking – by impartial experts – of the assessment of a building or project by a qualified and licensed BREEAM Assessor to ensure that it meets the quality and performance standards of the scheme.

The main output from a certified BREEAM assessment is the rating. A certified rating reflects the performance achieved by a project and its stakeholders, as measured against the standard and its benchmarks. The rating enables comparability between projects and provides reassurance to customers and users, in turn underpinning the quality and value of the asset.

The BREEAM ratings range from Acceptable (In-Use scheme only) to Pass, Good, Very Good, Excellent to Outstanding and it is reflected in a series of stars on the BREEAM certificate.

How it works

BREEAM awards credits for responsibly sourcing construction products to encourage responsible product specification and procurement in construction. To achieve these credits, applicable specified products must be covered by Environmental Management System (EMS) or a Responsible Sourcing Certification Scheme (RSCS) recognised by BREEAM.

ASI completed the BREEAM evaluation process in April 2020. Being a recognised Responsible Sourcing Certification Scheme means that ASI Aluminium products can be identified and checked by construction product specifiers and BREEAM Assessors during BREEAM assessments.

The table below is taken from Guidance Note GN 18, which contains the score levels for RSCS that are recognised by BREEAM for use in BREEAM and HQM assessments, along with respective guidance:
