BREEAM + LEEDS
Last updated January 6th, 2026
What is the difference between LEED and BREEAM?
LEED is a US-based green building certification system, similar in purpose to the UK’s BREEAM scheme.
BREEAM (Building Research Establishment Environmental Assessment Methodology), first published by the Building Research Establishment (BRE) in 1990, is the world’s longest-established method for assessing, rating, and certifying the sustainability of buildings.
LEED (Leadership in Energy and Environmental Design) began in 1994 as a single standard for new construction and has since evolved into a comprehensive suite of interrelated certification standards. These standards cover the full lifecycle of a building, from design and construction through to maintenance and operation.
Today, LEED is one of the most widely used green building certification programmes worldwide. Although LEED and BREEAM differ in structure and assessment criteria, both systems share the same objective: to promote environmentally responsible and sustainable practices in new-build and refurbishment projects.
Do individual products contribute directly to LEED or BREEAM credits?
According to the Building Research Establishment (BRE), individual components—such as cavity closers are not typically assessed in isolation under BREEAM and do not independently gain credits within the Green Guide to Specification. This is because BREEAM and LEED assess the sustainability performance of a building as a whole, rather than individual products.
How does the brand support sustainable construction?
Despite this, specifiers and contractors are increasingly prioritising environmentally responsible product choices as part of a wider commitment to sustainable construction. In response, manufacturers are taking proactive steps to align their products and processes with these expectations.
Dacatie is committed to supporting sustainable construction through responsible manufacturing practices, even where products do not directly influence LEED or BREEAM scores. This includes the adoption of LEAN manufacturing principles, environmentally sustainable processes, and recognised environmental management standards such as ISO 14001.
While individual products may not be evaluated independently under LEED or BREEAM, Dacatie remains dedicated to delivering solutions that contribute positively to sustainable building practices in the UK and internationally.
