Bo01: Environmental Approach

Ecological building No hazardous materials Built for users utilize in an environmental

friendly and resource efficient way Quality Programme

Biodiversity Compensation for the natural area Roofs and walls will be covered with plants Rainwater and seawater is used in public spaces to

support a broad range of species Large trees and bushes area

17

Bo01: Environmental Approach (cont. 1)

Energy100% renewable energy (sun, wind and water)Balanced between production and energy useElectricity from Sun (120m2 of

solar cells produce electricity)Electricity from Wind (large

wind power station)Heat from Water and Sun

Heat pump used for extracts heat from seawater1,400m2 of solar collectors

complement with heat pump

18

Bo01: Environmental Approach (cont. 2)

Eco-cycle Recycling of water and resources Recycling of wastes

Organic waste transformed to biogas Household waste separated for recycling Extract heat from Incineration process

Mobility system Well cycling system Public transportation system

with environmentally-friendly fuels Carpool system (Car sharing)

19

Bo01: Environmental Approach (cont. 3)

Information technology Monitoring the water and energy consumption status Indicated the departure time for buses The carpool of the district can be

booked on the home computer

Compare with Sweden’s normal houses in 2001 The energy consumes less 20-31% The water consumes less 10% Construction material consumes less 10% Construction material waste less 20%
