HAFENCITY WEST: SUSTAINABLE URBAN DEVELOPMENT CENTRAL HEATING SUPPLY
Central Heating SupplyObjectives (2002):
• secured supply• low price• high energy efficiency• CO2-Benchmark: below200 g/kWh:
target value 175 g/kWh
Mix of Technologies:
• district heating• solar heating• fuel cells
Result: Reduction of emmissions by central heating supply and CO2 limits.Reduction of CO2 emissions by 27% compared to natural gas use (even larger reductionspossible compared to oil or coal use)

SUSTAINABLE BUILDING CONCEPTS
Eco Label Categories
1. Sustainable use of energy ressourcespower requirements: residential buildings: <60 kWh/a m² or <40 kWh/a m²
power requirements: commercial buildings: < 190 kWh/a m² or <100 kWh/a m²2. Sustainable use of public goods
3. Use of environmentally friendly building materials
4. Special consideration for environment, comfort and health protection
5. Sustainable Facility Management
Usage of Competition and Market Processes• awarding of an eco-label and confering an environmentalaward
• certification of buildings
• promotion of energy efficient buildings in case of exclusiveoptions or/and the sale of plots under competitive marketconditions
