BSRIA
BSRIA is a consultancy, test and research organisation serving construction and building services companies and their clients.
Their publications cover building services relating to wastes but there appears to be little or no BSRIA-published information on resource efficiency in the manufacture of building services. They offer publications and consultancy in relation to building services and issues such as air-tightness.
