Performance

Monitoring conducted in 2003 found that BedZED had achieved these reductions in comparison to UK averages:
  • Space-heating requirements were 88% less
  • Hot-water consumption was 57% less
  • The electrical power used, at 3 kilowatt hours per person per day, was 25% less than the UK average; 11% of this was produced by solar panels. The remainder normally would be produced by a combined-heat-and-power

Embodied carbon

The greenhouse gasses released as a result of building construction - the embodied carbon in buildings—is usually ignored. But it was calculated for BedZED by one of the project initiators, BioRegional

It was founded in 1992 on the belief that overconsumption of resources was the driving force behind environmental degradation, and set out to find new ways to meet more of their needs...

. They say:


the embodied environmental impacts of BedZED’s construction materials are within the same range as standard UK housing. The total embodied CO2 of BedZED is 675kg/m2, whilst typical volume house builders build to 600-800kg/m2.



This means a 100m2 flat in BedZED has embodied carbon of 67.5 tonnes CO2. Compare this to carbon rations suggested in the GreenRationBook http://www.greenrationbook.org.uk/ :


The average UK citizen creates 11 tonnes of carbon dioxide equivalent (CO2e) a year. New UK targets aim to cut this by 80%. Dividing the ration equally between categories "consumables", "building", "transport" and "government", allows 1.5kg per day.


This argument gives a ration for building of 500 kg CO2e per person per year. For two people living in an average-sized 3-bedroomed flat, the 67.5 tonnes CO2e is 60+ years of their building ration. That's before the flat is heated, the fridge switched on and the impact of all the other necessary buildings (shops, offices schools etc.) are considered.
