Collections care in temperate zones of the world, including Scotland, is generally well served by a system of heating control known as conservation heating or humidistat-controlled heating. This system adjusts temperature in a building in order to maintain relative humidity at desired levels. An alternative control method is through the use of dehumidification, although airtightness of the building influences the effectiveness of this. This paper assesses three sites where these methods of control have been used: the Great Hall at Edinburgh Castle, Abbots House at Arbroath Abbey in eastern Scotland and Skelmorlie Aisle in western Scotland. The benefits of each system are discussed, together with consideration of the effect of climate change on the efficacy of each. [ABSTRACT FROM AUTHOR]

England's East Anglian region has c.550 late-medieval screens still in their original churches, one of Northern Europe's most significant in situ collections of medieval panel painting. The churches are managed by non-specialist volunteers and are not museums. In many, congregations are shrinking and long-term sustainability will involve varying uses of the building. The buildings and their collections are at risk from, among other factors, weather, groundwater, fire, heat, moisture, light, pollutants and pests, as well as vandalism and theft. The same threats affect screens, causing flaking paint, microbiological growth, insect damage and photodegradation. A collaborative programme was forged between the Hamilton Kerr Institute, University of Cambridge, specialists in medieval panel painting conservation, and Tobit Curteis Associates, specialists in environmental deterioration in historic buildings, supported by the Church of England's Cathedral and Church Buildings Division. This project aimed to bridge the gap between the conservation of sensitive artefacts and the conservation of the buildings in which they are situated. A methodology, utilising materials analysis, environmental monitoring and building and object surveys, was devised for the assessment of the deterioration of screens and their churches to produce holistic recommendations. Through a pilot study, solutions that are passive, cost effective, innovative and sustainable are being implemented. [ABSTRACT FROM AUTHOR]
