The multi-award winning development is one of themost exemplary examples of sustainable living in the United Kingdom.Located in Hackbridge, South London, BedZED is sited on a brown fieldsite which is adjacent to a creek. BedZED comprises 100 homes,community facilities and enough workspace for 100 persons. Residentshave been living at BedZED since March 2002.BedZED exclusively utilizes renewable energy sources which aregenerated on site and that are carbon neutral reducing the emissionsof carbon dioxide from site, building, and resident.Beddington zeroAmy fasnacht Greg nakata Katie olinEnergy developmentasustainablesite+building Case studyThursday 15 April 2010 + architecture 464Heating degree days: 5960 base 65 FCooling degree days: 1411 base 50 FAnnual precipitation: 23inBuilding Type: Multifamily Residential/Mixed UseOwned + Managed by Peabody TrustArchitect Bill Dunster ArchitectsCommissioned by Bio RegionalCompletion 2002introduction

The rainwater harvestingsystem also needs to bereconnected to help storm watermitigation and the grey waterrecycling process.51To help mitigate the excessive storm water, we propose theimplementation of a large bioswale/rain garden where the currentfootball pitch is located on site. This would help to alleviate the impactfrom any excess runoff from the site, and filter the water before itreaches a larger body of water north of the site. |t could also serveas a rain garden and become a sustainable feature of this housingdevelopment, as well as an example of public awareness on stormwater mitigation. This area could also serve as a great location forimplementation of wildlife habitat.Beddington zeroAmy fasnacht Greg nakata Katie olinEnergy developmentasustainablesite+building Case studyThursday 15 April 2010 + architecture 464Some of the issues preventing BedZed to have ahigher score include not optimizing energyperformance, excess storm water run off, rainwaterharvesting deactivated, living machine inefficiencies,no potable water, petrol transport vehicles, and highuser ignorance…Leed rating: goldBreeam rating:ExcellentRiba sustainability awardanalysisBeddington zeroAmy fasnacht Greg nakata Katie olinEnergy developmentsustainableasite+building Case studyThursday 15 April 2010 + architecture 464As well as the solar heating and photovoltaics that exist onsite, a 130kw combined heat and power [chp] generation plantthat burns regionally produced carbon-neutral biofuel hasbeen constructed for BedZed. This is intended to be beneficialfor the facility by providing energy for heat, as well water, butthe residents don’t utilize it for hot water use. The system isalso somewhat inefficient, and needs to be better constructedas to not lose energy. Wind turbines on site could alsolessen dependency on the CHP fac.ility.redesign
