Contributing to BREEAM

BREEAM: (Building Research Establishment Environmental Assessment Method) is a widely known environmental assessment method for buildings. The system sets the standard for best practice in sustainable building design, construction and operation.

The Benchmarks: Outstanding – ≥85% Excellent – ≥70% Very good – ≥55% Good – ≥45% Pass – ≥30 Unclassified – <30

The Categories: A BREEAM assessment uses recognised measures of performance, set against the established benchmarks, to evaluate a building’s specification, design, construction and use. Credits are awarded across ten categories based on the outcomes of the building assessed. The credits are then combined to provide a single score, achieving either a Pass, Good, Very Good, Excellent or Outstanding overall BREEAM rating.

BREEAM icons and category weights

Hambleside Danelaw is the first rooflight manufacturer to receive a product EPD for rooflights. This means that when specifying Zenon rooflights, they can contribute a minimum of 1.5 points, in addition to the metal roof system, towards the building’s overall BREEAM rating. These EPD points fall under the category of Material – Criterion Mat 02.

Over and above the metal roof system, rooflights can also contribute to two other categories, Energy and Health and Wellbeing, and two other criterion for the Material Category.

When rooflights are incorporated at Concept Design RIBA stage 2 (essential for any calculation based credits such as Ene 01 and Mat 01), the contribution is easy to apply and are low to no cost. Rooflights can, however, be considered at a later stage of procurement and can help to recover credits lost unexpectedly from the initial plan.
