Passivhaus principles applied to deep storage facility
Architype for Imperial War Museums
Contract value: undisclosed
This deep storage facility unites the IWM paper collections into one central repository. The store holds wartime artefacts from the last 100 years, including Nuremberg Trials documents. As well as responding sensitively to the conservation area of IWM’s historic site, the low carbon building was cost-effective to build – as it is to maintain and run. Following the Passivhaus approach it uses the ground to moderate temperatures naturally. Airtightness standards are 160 times better than required by building regulations and the use of non-toxic materials creates a high quality atmosphere. The building allows easy access for archivists and incorporates robust gas suppression systems; its walls provide four hours of fire resistance behind the Corten steel facade.
