bre is developing a system of environmental profiles for building materials and components. The profiles set out energy use, constituent materials, wastes and other emissions 'from cradle to grave', spanning a nominal, 60-year life cycle. In some cases this life will include several cycles of maintenance, and less frequently, replacement.
There are separate generic profiles so far for common materials such as forms of aggregates, masonry, copper, steel, timber and insulation. These profiles were developed and agreed upon in association with the 24 trade associations.
A new report, describing the profiling methodology, is available from crc for £75 plus £5 post and packaging: bre Methodology for Environmental Profiles of Construction Materials, Components and Buildings, by Howard, Edwards and Anderson, for £75; tel 0171 505 6622. Profile data is available on subscription. Database membership costs £200/year for academics and organisations with a turnover below £2 million. Above that, the cost is £500/year.
