Benchmarking: Case Study of Bo01 (City of Tomorrow) • A newly constructed urban district with about 600 apartments and a temporary exhibition for 2001 European Housing Expo • Located on waterfront inSweden’s Malmö city • Funding • Local government • National government • European Union • Public-private partnership

14. Before: • polluted Industrial wasteland • Now: • International leading ecological area • sustainable city with residential buildings and some commercial offices

15. Bo01 Sai Kung Town 1:1proportion Apartment: 600 Population: 1100 Floor: 3-5 Apartment: 1100 Population: 4000 Floor: 3-11

16. Bo01: Environmental Approach • Ecological building • No hazardous materials • Built for users utilize in an environmentalfriendly 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) • Energy • 100% renewable energy (sun, wind and water) • Balanced between production and energy use • Electricity from Sun (120m2 ofsolar cells produce electricity) • Electricity from Wind (largewind power station) • Heat from Water and Sun • Heat pump used for extracts heat from seawater • 1,400m2 of solar collectorscomplement 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 systemwith 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 bebooked 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%

20. Alternatives Generations • Recycling • Separation of Domestic waste for Recovery and Disposal • Use Compress Machine to compress the Recyclable Wastes for easy storage • Energy Saving • Promotion of Electronics Products with Energy Efficiency Labeling Scheme with Environmental Friendly Materials • Install High Efficiency Lighting System • Install Occupancy Sensor Control in Lighting System

21. Alternatives Generations (cont.) • Biodiversity • Greening in common/private areas for compensate the natural scene and improve air quality • Mobility • Use of public transport instead of private cars • Promote cycling • Propose environmental friendly fuel vehicles • Ecological Interior Decoration • Provide guidelines for residents and interior decoration companies
