Stable Environments for Precious Objects and People
Following the success of the Hereford Archive and Records Centre with Architype we have worked on a number of high profile passive archives. Our approach is very much inspired and informed by the work of Tim Padfield and his colleagues in Denmark. We have also incorporated our Passivhaus experience of designing airtight and thermally sound buildings. See the resources page for technical papers on our approach.
We are also working on a number of existing museums, galleries and archives where there have been problems, often due to failure of complex and expensive air conditioning plant.
The picture above is typical of a small archive plant room. It shows only part of the plant at Dorset History Centre. This has been turned off with the exception of a small chiller and dehumidifier servicing a photo store. Often simply turning off the air-conditioning can result in improved conditions and dramatic energy savings. However other measures are usually required to maintain good conditions from season to season. Every projects throws up its own challenges to keep us interested.
HARC Passivhaus Certified Archive, Hereford 2013 – 2014
We worked with Architype to develop an approach to radically reduce the energy requirements for the new Herefordshire Archive and Records Centre. The energy strategy for the repository owes much to the work of Tim Padfield. This is the first Passivhaus Archive in the UK and the second in the world to be certified. It is also the first repository designed to the new Standard for archival materials storage, PD 5454.
Although this was the contractor’s first Passivhaus project, it seems likely that Kier Construction have delivered one of the most airtight buildings in the world!
The building was completed in January 2015 and we receive monthly data on conditions in the repositories.

Imperial War Museum Duxford 2018
We have worked with Architype to design a large paper store designed for cool passive storage. The building is ground-coupled with no heating. It incorporates an innovative supply air dehumidification system developed with Alan Clarke and Andy Jarvis (E3) with additional inspiration from John Cantor. Completion is due in early 2019 and you can read about the approach in this paper presented by Andy Jarvis at the 2018 Passivhaus Conference in Munich.
Carmarthen Archive 2018 – 2019
We are working with Acanthus Holden Architects and Piers Sadler Consulting on this new archive repository and associated search room and offices. As with the other new-build archive buildings on this page, the repository design follows the passive Danish approach but the building will be Passivhaus certified.

St Andrews Library Store
This existing repository building was suffering from poor environmental conditions. Working with Architype we have been able to move to a more passive strategy. This has stabilised the environment and dramatically reduced energy consumption. We are managing to achieve this by using the existing plant but with some hardware and software changes. We carried out air tightness testing with Thermal Image UK and helped builders implement improvements to the building airtightness.
Birmingham Museum and Art Gallery 2018
Working with Architype and the museum and gallery conservators, we are exploring the potential to reduce energy consumption and improve conditions for staff and objects. We have carried out experimental airtightness measures and are measuring the results by monitoring CO₂ levels and overnight decay.
Dorset History Centre 2017-2019
Implementing the recommendations from the earlier consultancy by Tim Padfield, we are working with Architype to implement a more passive approach to maintaining suitable conditions for the collection. We carried out airtightness testing and thermal imaging followed by some light-touch interventions to build on earlier experiments to run the stores with the air conditioning turned off. Monitoring during the summer of 2018 allowed us to confirm that temperatures would be acceptable without cooling. As is often the case when working with existing archive buildings, we are taking a very hands-on step-by-step approach.

National Galleries Scotland 2015
Working with Architype, we have carried out troubleshooting at a number of NGS buildings including Modern 1 Gallery in Edinburgh. These have led to very simple interventions achieving significant improvements in environmental conditions for art and people.
