An
introduction
Demands for environmental improvements within construction are
growing rapidly from all sides including building designers and
their clients – as well as government with its ‘Code
for Sustainable Buildings’ and ‘liveability’
initiative which are also expected to take a broad view.
Sustainability’ remains difficult to define or apply
quantitative measures to. Various guides are available comparing
the ‘embodied impact’ of different materials or
constructions – notably the BRE ‘Green Guide to
Specification’ – but they recognise that, in many
situations, doors have a limited effect on the overall embodied
impact of a building, being only a small proportion of the
overall mass.
However, the wider environmental characteristics of different
door types can be substantial. There are also other issues to
consider such as adoption of factory-assembled doorsets to
improve environmental efficiency, techniques to maximise
operational design life and, particularly, use of verifiable
sustainable timber sources.
