13 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 in Sweden’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 1:1 proportion Sai Kung Town 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 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) Energy 100% renewable energy (sun, wind and water) Balanced between production and energy use Electricity from Sun (120m 2 of solar cells produce electricity) Electricity from Wind (large wind power station) Heat from Water and Sun Heat pump used for extracts heat from seawater 1,400m 2 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%

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
