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
