We live in a 24 hour get-this-done-and-over-with culture, so to establish what we do in Transition in time requires a steady and deliberate process. On the blog we do this by heralding events and then covering them (with text and images), and threading them back into our more reflective pieces.

Here is a piece from our Transition Themes Week #11 from a seasonal and investigative scheme, Norwich Energy Lookouts!

An Open and Shut Case by Chris Hull
11 January 2012
Opening doors seem to emerge as metaphors for so many things, and in so many different fields and disciplines. From the football commentator's description of a team's defence being "like an open door", to doorways ( and stairways) to heaven, to many an artist's depiction of light and dark either side of a doorway. This seems to be a very long way from the pure functionality of a door!
When we launched the Energy Look Out initiative a couple of months ago, inviting people to tell us examples of everyday energy wastage in Norwich, we had several comments about the practice of shops and stores wedging doors open, with the consequent huge and rapid loss of heat from inside to out. Years ago, as a Councillor, I had occasion to take up this very issue with particular shops in Norwich following complaints.
- the differences in perception from one group of people to another over the same issue
- a firmly held belief that is not actually supported by evidence (see below)
- a linkage between commercial practice and public behaviour
- a widespread practice that is actually responsible for high carbon emissions and financial cost, and which does not involve any cost or investment to change
The practice of propping doors open persists, however....all the more surprising when the research carried out by Cambridge University on the energy and carbon wastage involved says shutting the door will:
- Reduce energy usage by up to 50%
- Cut a shop’s annual CO2 emissions by up to 10 tonnes of CO2
- Maintain energy use at a standard low level
- Enable heating to be shut off long before the end of the day without affecting internal temperatures
- Stop need for so-called “air curtains” over the door – among the greatest wasters of energy: a single one consumes 24 kWh per day. This is equivalent to emitting 91 kg CO2 per week. The research found no conclusive evidence that footfall or transactions were affected by closing the shop door.(2)
I never thought I would get so excited about doors.
