Setting the Standard for Sustainability

These days clients and investors are demanding that buildings have excellent environmental and sustainability credentials.

Which is why BREEAM (Building Research Establishment’s Environmental Assessment Method) was introduced in 1990. Today BREEAM is the world’s most widely used sustainable building certification scheme providing a benchmark for performance which can be used by clients, investors, developers and design teams.

More than 250,000 buildings already have certified BREEAM assessment ratings and over a million have been registered for assessment since BREEAM was first launched.

BREEAM sets the standard for best practice in sustainable building design, construction and operation.

Commercial Benefits of BREEAM Certification

Many investors are already aware that sustainability impacts value. BREEAM certified buildings command higher sale and rental values, they are quicker to sell and rent, cheaper to run, attract better quality tenants, have higher occupancy rates and so offer better long term value and represent low risk assets.

As more and more clients are specifying minimum BREEAM ratings for both new builds and refurbishments, it is essential to understand how maximum BREEAM credits can be achieved.

What is a BREEAM Assessment?

A BREEAM assessment uses recognised measures of performance, set against established benchmarks, to evaluate a building’s specification, design, construction and use.

Credits are awarded across ten categories based on the thermal performance of the building assessed. These are weighted according to the relative impact of each environmental issue.

The credits are then combined to provide a single score, achieving one of 5 BREEAM ratings from Pass to Outstanding.

How to Gain BREEAM Credits

A BREEAM project can achieve up to 109 credits whilst Innovation provides opportunities for up to 10 bonus credits. The minimum percentage to be BREEAM certified is 30% (equivalent to 33 credits). Higher levels of compliance are possible leading to different ranking.

BREEAM does not certify a product, but with very careful specification of the fenestration material and glass choice, up to 40 credits of the 119 available can be obtained for new buildings.

BREEAM credits for fenestration are available in several areas, not just the materials element:
