bedzed london uk Flashcards
what is a bedzed
BedZED’s are low-energy-emission concept eco friendly concept,

Zero energy—The project is designed to use only energy from renewable sources generated on site.
solar panels
There are 777 square metres (8,360 sq ft) of solar panels. Tree waste fuels the development’s cogeneration plant (downdraft gasifier) to provide district heating and electricity.
technical implementation problems
The gasifier is not being used, because of technical implementation problems, though the technology has been and is being used successfully at other sites.
High quality apartment
High quality—The apartments are finished to a high standard to attract the urban professional.
average ecological footprint of a BedZED resident is…………
the average ecological footprint of a BedZED resident is 4.67 global hectares (2.6 planets),
The ‘Living Machine’ water
The ‘Living Machine’ water recycling facility had been unable to clean the water sufficiently. The cost of the facility also made it unviable.[4]
The biomass wood chip boiler problems
The biomass wood chip boiler (biomass gasifier) was no longer in operation and the backup power source, a gas boiler, is now used.
water consumption
water consumption has been reduced by 50%, or 67% compared to a power-shower household.
The residents’ car mileage is 65% less.
Problems
Hot-water consumption and heating requirements
Space-heating requirements were 88% less.
Hot-water consumption was 57% less.
the UK average vs bedzed averages
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.
Energy efficient
Energy efficient—The houses face south to take advantage of solar gain, are triple glazed, and have high thermal insulation.
Water efficient
Water efficient—Most rain water falling on the site is collected and reused. Appliances are chosen to be water-efficient and use recycled water when possible. A “living machine” system of recycling waste water was installed, but is not operating.
Waste recycling
Waste recycling—Refuse-collection facilities are designed to support recycling.
Electric and liquefied-petroleum-gas cars
Electric and liquefied-petroleum-gas cars have priority over cars that burn petrol and diesel, and electricity is provided in parking spaces for charging electric cars.
