  • OPC is about creating better places to live evidence for example from BedZED that over 2/3rds of people report that they have a higher quality of life compared to where they lived previously Not about doing without or a ‘hairshirt’ existence – it is about how we will live in the 21 st century making the most of green technologies and the latest thinking in community development and placemaking
  • Concepts developed in 1997 as joint effort Bill Dunster Architects, Arup and BioRegional One Planet Living as an idea grew out of BioRegional’s monitoring of BedZED not everything has worked, but a lot has worked and many lessons learned was not financially successful (ultimately it was a prototype) but ‘2 nd generation’ projects like One Brighton have been built cost effectively
  • South facing residential units with conservatories North facing commercial units with skylights good to prevent office overheating Wind-driven ventilation cowls
  • Superinsulation has worked very well achieving Passivhaus levels Some overheating of sunspaces in summer – when have superinsulated building, passive solar gain for heating is less important
  • - Approximately half the electricity consumption of London average
  • Rainwater recycling worked well
  • Decommissioned and operates on demonstration membrane bioreactor operated by Thames Water Analysis shows conventional sewage treatment is a good environmental option anyway
  • Reduced parking from 160 to 100 Created car-free centre – Home Zone – where children can play safely and people can meet Introduced London’s first car club – now a London-wide network
  • - Gets close to One Planet footprint – recycles diligently, member of car club, buys local food
  • Steve still runs 2 cars so transport footprint large If lived in a conventional home would have 4 planet footprint Thinking of changing one of his cars to a low carbon vehcile which will save half a planet So choices will always be important ‘ hardware’ of sustainable infrastructure like energy, water, waste needs to be complement by ‘software’ of sustainable choices
  • Sense of community was valued most, 84% felt community facilities better than previous neighbourhoods, Residents know an average of 20 of their neighbours - local average is 8. People engaged in society are more likely to be happier and healthier (NHS, 2004)
  • Former Hewlett Packard data centre retrofitted with what was at the time California’s largest private PV array converted into a business centre and green incubator 650 jobs on-site - Will reuse a total 700,000 square feet of buildings creating a new town square
  • - New urbanist plan ensures every resident is no more than a five-minute walk to groceries, restaurants, day care and other amenities offering local, sustainable, and fair trade products and services. - Clustered around a new daily farmer&apos;s market Residential development will start when market improves - Will be sold with convenience of ‘5 minute living’ (commuting is often reported as the number cause of reducing quality of life)
  • Only when create sustainable lifestyle do we start getting the size of carbon savings we need - One Planet goes beyond conventional green rating systems as it looks at all impacts and absolute impacts, not just reducing carbon emissions
  • Backed by Quintain Estates and Development – London Stock Market listed company One Brighton built out in 50:50 joint venture with leading UK housebuilder, Crest Nicholson PLC 172 apartments and 2000m2 office and community space private car free – only car club and disabled-user spaces exceeds BedZED performance but within conventional over cost for city centre development of £ 190/sqft
  • Sales website not primarily about leading a green lifestyle Sold as high quality 21 st century lifestyle or which green living is one part hooks onto other trends – eg for local food which celeb chefs are telling us we should eat because it tastes better; and healthy living including walking and cycling more; and convenience of services such as the car club
  • Overall sold very well Smart modern apartments Whereas other development selling 1-2 apartments per week, we were selling 2-3 No green premium but increased sales velocity which is as valuable (as pay back bank loans quicker saving on interest payments) features like roof top allotments and communal sky gardens proved very popular
  • Charges comparable to other new home but green rather than brown Some customer resistance to high standing charge but low variable charge which is unconventional
  • BioRegional One Planet Communities induction: Lessons from One Planet Communities - 2011

    1. 1. Lessons from One Planet Communities
    2. 2. Some key lessons <ul><li>1. Large carbon and ecological footprint reductions are only possible be creating a whole green lifestyle </li></ul><ul><li>2.Sales, rentals and customer satisfaction are higher than average </li></ul><ul><li>3. Best outcome by really embedding One Planet Living by training everyone in the principles </li></ul><ul><li>4. People’s lifestyle choices will always be important and be a key determinant of footprint </li></ul>
    3. 3. BedZED – prototype One Planet Community <ul><li>Concepts developed in 1997 by Bill Dunster Architects, Arup and BioRegional </li></ul><ul><li>One Planet Living as an idea grew out of BioRegional’s monitoring of BedZED </li></ul>
    4. 4. 100 homes – mixed private and social 1 bed – 4 bed 2500m2 commercial/community 100 homes/ha core density BedZED – statistics
    5. 5. BedZED Targets <ul><li>Reduce total energy demand by 60% of UK average </li></ul><ul><li>Maximises passive solar gain – “zero heating” </li></ul><ul><li>Produce all energy on-site from renewables – zero fossil energy development </li></ul><ul><li>Reduce private car fossil fuel mileage by 50% </li></ul><ul><li>Reduce car ownership from 1.6 per household to 1 </li></ul><ul><li>Use reclaimed and recycled materials where possible </li></ul><ul><li>Source 50% of construction materials within 35 miles </li></ul>
    6. 6. <ul><li>Reduce water consumption by 33% of UK average </li></ul><ul><li>Black, grey and rainwater treated on site in the ‘Living Machine’ </li></ul><ul><li>Minimise generation of household waste and increased recycling to 60% </li></ul><ul><li>25% of households purchase local organic food </li></ul><ul><li>To create aspirational homes good to live in </li></ul><ul><li>Combat social isolation and create integrated community people want to live in </li></ul>BedZED Targets…continued
