Just back from a research visit from the Science Museum's stores at Wroughton. Great to see a low-energy philosophy informing the retrofit of one of their Second World War aircraft hangars.
Instead of putting lots of energy hungry air handling equipment in the store, the approach has been to increase installation and airtightness with a new external skin on the old frame. It's become a building which is passive. It's not just green: it's also cheaper to run. Very encouraging.
