Soft Harbour HafenCity
(partially)
public regulations
Noise Cap (Harbour Planning Ordinance)
1. development plans allow residential development without double facade 2. building permits: specific window concepts and noise absorption / location of bedrooms
private regulations
sales contracts: users accepting harbour noise (easement)

HAFENCITY WEST: SUSTAINABLE URBAN DEVELOPMENT CENTRAL HEATING SUPPLY
Central Heating Supply Objectives (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 reductions possible compared to oil or coal use)
HAFENCITY EAST (> 1 Mio. m² GFS): NEW STANDARDS FOR CENTRAL HEATING SUPPLY (CO2-BENCHMARK 89 g/kWh) Supply Area Eastern HafenCity: CO2-Benchmark: 89 g / kWh (Contract 2009) 1. wood pellets incineration (waste wood of Großmarkt and other waste wood) 2. low-temperature boiler for peak loads
Western HafenCity: district heating system 1 fuel cell technology (biomethane) locally completed with : 2. low-temperature boiler for peak loads 1. fuel cells 2. solar heating 3. CHP units

SUSTAINABLE BUILDING CONCEPTS
Eco Label Categories 1. Sustainable use of energy ressources power requirements: residential buildings: <60 kWh/a m² or <40 kWh/a m² power requirements: commercial buildings: < 190 kWh/a m² or <100 kWh/a m²
2. 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 environmental award • certification of buildings • promotion of energy efficient buildings in case of exclusive options or/and the sale of plots under competitive market conditions
