The Green Guide - BRE
BRE is an independent and impartial, research-based consultancy,
testing and training organisation, offering expertise in every
aspect of the built environment and associated industries. They
help clients create better, safer and more sustainable products,
buildings, communities and businesses.
Jewson recognises the importance of an independently verified
system of assessing the 'sustainability' of different products and
specifications. The most comprehensive system is currently
published online by the BRE (Building Research Establishment).
The environmental rankings are based on Life Cycle Assessments
(LCA), using BRE's Environmental Profiles Methodology 2008.
Materials and components are arranged on an elemental basis so
that designers and specifiers can compare and select from
comparable systems or materials as they compile their
specification. The elements covered are:
- External walls
- Internal walls and partitions
- Ground floors
- Upper floors
- Floor finishes
Ratings for floor finishes, windows and insulation are assessed
in isolation without any other materials within the specification;
the rating therefore directly refers to the product.
Across these building element categories the Green Guide
provides an extensive, but not exhaustive, catalogue of building
specifications covering most common building materials.
Green Guide Ratings
The ratings referred to in this Jewson guide are all A+ and A
ratings with information about alternative specifications. Please
consult the Green Guide Online for more information.
Access to the Green Guide Online is free, but requires users to
register prior to use at www.thegreenguide.org.uk.
Please note that generic ratings published in the Green Guide
are not specific to any one proprietary product and it is important
that their use does not convey that impression. A product could be
used in a number of different specifications, which could each
achieve different ratings.
Embodied Impact on Materials
For the embodied impacts of materials the Code for Sustainable
Homes uses the Green Guide as the means to rate materials for
credits. The Green Guide is based on life cycle assessments that
look at the whole life cycle of materials from extraction (cradle)
to end of life (grave), including an option to look at future uses,
i.e. recyclability (cradle-to-cradle).
"It's great to see Jewson playing their part in taking
sustainable materials forward, guiding their customers through the
many new and different types of materials now available." -
