have been invited to participate on
the basis of their established involvement in the
heritage retrofit field and the suitability of some of
their products and services for traditional buildings.
Some of the participants also supply products and
services to other areas of the building market which
have no application in the heritage retrofit field.

FROM THE EDITORS
The contribution made by the UK’s older buildings to climate change should not be
ignored. Our country has the second highest level of greenhouse gas emissions in
Europe, 557 million tonnes in 2014. Energy-use in buildings is responsible for a third of
this, and almost a quarter of our homes are over a century old. If our grandchildren are
to avoid catastrophe, the government’s target of an 80 per cent reduction in greenhouse
gas emissions by 2050 must be met, and all buildings must play their part.
Older buildings should, however, be treated carefully as modern retrofit technology
can be highly damaging to older structures and counter-productive. In this rapidly
developing field, new research is revealing how we can make best use of their strengths
and resolve their weaknesses, and developments in both modern and traditional
technologies are helping us to keep them warm and dry sustainably. The aim of this
publication is to bring the latest information to those who need it most.
