The Effect on the Historic Environment
It is predicted that Scotland will become warmer and wetter and there will be an increase in annual rainfall of between 5 to 20 percent by the end of the next century.
Our archaeology and coastal landscapes are vulnerable to coastal erosion, rises in sea level, flooding and storminess. Some of Scotland’s unique and special sites such as Skara Brae in Orkney are most at risk.
More rainfall will mean that traditional buildings will be wetter for longer periods of time resulting in increased weathering of stone, algal and fungal growth and corrosion of metals. It will be vitally important that buildings are well maintained and managed to ensure that they can withstand increased rainfall and weathering.
All measures to improve energy efficiency in traditional buildings should be considered carefully with thought given to the carbon footprint, longevity and sustainability of existing and replacement materials.
In improving energy efficiency it is important to avoid damaging effects on traditional buildings. For example, reducing air leakage in buildings to prevent heat loss might result in condensation and mould growth, with damaging effects on the building fabric and the health of those living there.
