Reviewing environmental conditions - reducing museums' carbon footprint

NMDC recognises that museums need to approach long-term collections care in a way that does not require excessive use of energy, whilst recognising their duty of care to collections. There is general agreement within the international museums community that it is time to shift policies for environmental control, loan conditions and the guidance given to architects and engineers from the prescription of close control of ambient conditions throughout buildings and exhibition galleries to a more mutual understanding of the real conservation needs of different categories of object, which have widely different requirements and may have been exposed to very different environmental conditions in the past.

PAS 198

Following publication of NMDC guidelines and an investigation by the AHRC/EPSRC Research Cluster, the British Standard Institute consulted on and published Publicly Available Specification 198: Specification for managing environmental conditions for cultural collections. This standard reflects research conducted since the publication of environmental guidance for museums, libraries and archives in British Standard 5454 (2000). The PAS 198 suggests users:

  • Evaluate the sensitivity of their collection in response to temperature, relative humidity, light and pollution, recognising that different materials react in different ways to agents of deterioration;
  • Think holistically and put in place an environmental strategy appropriate for the collection (and which takes into account the expected lifetime of the collection);
  • Make decisions about suitable environments on the basis of the significance, condition, use or display of those specific objects.

NMDC guiding principles

NMDC developed a set of guiding principles for rethinking policy and practice with the aim of minimising energy use in 2009. The guidelines were developed in consultation with UK conservators, ICON and the National Trust among others. NMDC members agreed to commit to these guidelines, signalling a move towards a less energy intensive approach to collections care. The guidelines were accepted by the European Bizot Group of major museums at their May 2009 meeting.
