BRE FB67 PDF

Introduction

This report provides a review of how biomaterials and biomass have been assessed in The Green Guide to Specification (fourth edition)[1], including the application of the BRE Environmental Profiles methodology[2], which underlies The Green Guide. Biomaterials are defined here as construction materials derived from plant or animal sources. Biomass refers to a biomaterial used for energy generation.

Whilst this report focuses predominantly on timber, woodbased panels and biomass energy, it has been produced as part of a series covering the background to the major material groups incorporated into The Green Guide. Many of the other reports in this series, eg Environmental impact of windows[3], may also be of interest when considering the environmental impact of biomass and biomaterials in construction.
