The Green Guide to Specification
Access the Green Guide
Green Guide online provides designers and specifiers with guidance for selecting construction materials and components. Materials and components are assessed in terms of their environmental impact across their entire life cycle - from ‘cradle to grave', within comparable specifications.
Environmental rankings
The Green Guide presents information on the environmental impacts of building elements and specifications by ranking them on an A+ to E rating scale. These environmental rankings are based on life cycle assessments(LCA), using our environmental profiles methodology. They are generic rankings that illustrate a range of typical materials.
Building types
The Green Guide examines the relative environmental impacts of the construction materials commonly used in six generic building types: commercial, educational, healthcare, retail, domestic and industrial. It covers more than 2,000 specifications.
Building elements
Materials and components are arranged on a building element basis so that you can compare and select from comparable systems or materials as you compile your specification. The elements covered are, external walls, internal walls and partitions, roofs, ground floors, upper floors, floor finishes, windows, insulation and landscaping. This extensive catalogue is continually being updated with specifications covering most common building materials.
