This third version of The Green Guide contains over 150 specifications commonly used in housing. The guide contains typical wall, roof, floor and other constructions listed against a simple environmental rating scale running from A (good) to C (poor). Twelve different environmental impacts are individually scored, together with an overall Summary Rating, information on recycling and typical costs. The Summary Ratings enable users to select materials and components on their overall environmental performance over the building's life. Because ratings are also given for individual environmental issues such as climate change, the specifier can alternatively select materials and components on the basis of personal or organisational preferences or priorities, or take specification decisions based on the performance of a material against a particular environmental parameter.
