Approach & strategy:
An initial desk study will be carried out to identify the climate
changes predicted to occur in the U.K. These will then be related to
roof design, specifications, construction and reported failures.
The project partners will identify a series of 'standard' designs used
as a benchmark for current construction. These will be assessed for
their suitability to withstand maximum climate changes as predicted
to occur by the end of the century. Other existing and hence older
property could reach the end of its useful life by 2050. Since these
would be replaced they would be subject to climate change less
severe than for currently constructed buildings. It is not intended
to include historic buildings in the scope. However the outputs from
this project will be relevant in part and could be used to mitigate
the effects of climate change for these buildings.
Having identified a number of 'standard' designs it will be necessary to
assess them for impact from predicted climate change. It will be
necessary work from the design to the specification and construction
stages. A number of roofs, provided by the partners, will be
inspected and assessed for the impact of climate change. This will
mean the likely mode(s) of failure will need to be identified.
The number of standard designs will be chosen to best reflect those
found in U.K. building stock. There are also regional variations in
construction particularly between England, Scotland and Northern
Ireland. These have been driven to a certain extent by regulation
but the regional variations are due mostly to climatic conditions
i.e. more extremes of weather in the north.
The potential changes in construction will be identified and then
related to the original specification for the roof. These will in
turn be related to design principles. It is necessary to examine the
relationship between the construction, specification and design
process to ensure any modifications made to the design can in fact
be achieved on a real roof construction site.
The current guides to good practice are well known to the Innovation.
Suggested modifications to critical details will be produced and
The discussions on designs of roofs will also take into account how the
roof itself could mitigate the effects of climatic change. This will
be considered as a separate issue from the main thrust of the
project. It will take into account the tenets for sustainable
roofing recently published by RILEM WG083.
