Noah's Ark project wins Europa Nostra Award
The EU 6th Framework Programme for Research project, Noah's Ark in
which UCL is a core partner has won an Europa Nostra Award.
The award for scientific research on the impact of global climate
change on the built heritage and cultural landscapes recognises the
research achievements of the European interdisciplinary research
consortium that has mapped and modelled for the first time the likely
impacts of a changing climate on the cultural heritage in Europe.
The Noah's Ark project examined the processes of material change in
building materials and ensembles, and the indoor environments of
historic buildings that often house irreplaceable fixtures, fittings,
furniture and decorative art. Important agents of change that were
studied include higher temperatures, precipitation, Flooding, Shifting
seasons, warmer winters and rising sea levels, as well as synergistic
effects such as wind-driven rain. The impacts that were studied include
accelerated decay of historic materials, changes in migration and
species in insect pests and lichen and the effects of wetting and
drying of historic buildings.
UCL's Centre for Sustainable Heritage at the Bartlett School of Graduate Studies was responsible three key tasks in the project:
The UCL team developed the European map for wind-driven rain for the periods 2010-2039 and 2070-2099 using data outputs from the General Hadley Model HadCM3 and the Regional Hadley Model HadRM3 and the moderately optimistic IPCC SREC A2 scenario. Maps of the changing moisture content of spruce wood a timber widely used in historic structures, brick and sandstone during the 21st century were also developed.
The UCL team applied Heat and Moisture movement computer models to examine the effect of climate change on historic buildings and used the models to examine the effects of different drying strategies. Drying strategies are important because, as the risk of damage to cultural heritage by flooding and the saturation of the building fabric increases, pressure will build to bring buildings back into use for heritage conservation, health, the economy and community cohesion. Tensions between the demand for rapid repair and long-term conservation will result. The UCL team simulated submerging a wooden church in water for 40 days and nights; it looked at the total moisture content of the building fabric over time and then studied the effect of natural drying and forced drying.
After 40 days of wetting, water penetrated the wooden walls of the church only a few centimeters in from both the external and internal surfaces. Without flooding, the moisture content of wooden walls is expected to decrease slightly in the 2020s and 2080s, while forced drying of wooden walls is expected to lead to over drying, and large changes in the internal moisture profile of the wood heightening the risk of damage.
The UCL team was also responsible for producing guidelines proposing
adaptation strategies for cultural heritage management in the face of
climate change. These guidelines are aimed at heritage owners and
managers of historic buildings and collections, policy makers and
national heritage organizations.
Professor May Cassar, Director of the Centre for Sustainable Heritage, and the UCL team leader on the Noah’s Ark project said:
"This award is outstanding recognition of truly ground-breaking research carried out at UCL and by the whole European consortium. This award is only the start. We are building on this success, having secured further EC support and a commercial publisher for The Atlas of Climate Change Impact on European Cultural Heritage Scientific Analysis and Management Strategies. It is simply amazing that as a result of Noah’s Ark so many countries including the US, NGOs including ICOMOS and ICCROM, UN bodies such as UNESCO, the World Bank and other European institutions including the European Parliament and the Council of Europe are beginning to build actions based in our research. Funding permitting, we have great plans to take this research forward."
UCL context
The UCL Centre for Sustainable Heritage was originally established with the support of three UCL departments: The Bartlett Faculty of the Built Environment, the Institute of Archaeology, and the School of Library, Archive and Information Studies. It consists an international interdisciplinary research team which identifies research gaps for the physical protection of the moveable and immovable heritage that only interdisciplinary collaboration can tackle.
The Europa Nostra Awards were jointly launched in 2002 by the European
Commission and Europa Nostra to celebrate outstanding initiatives
among the many facets of Europe's cultural heritage in categories
ranging from the restoration of buildings and their adaptation to new
uses, to urban and rural landscape rehabilitation, archaeological site
interpretations, and care for art collections. Prizes are also awarded
for research, dedicated service to heritage conservation by individuals
or organisations and education projects related to cultural heritage.
