Detail development Plans
Integrated Planning
Partial areas with 1000 flats divided on 10 developers. Meetings monthly with planners for water, energy, transport and waste.
Some facts in short for the project •size 160 ha + 40 ha lake (90 ha residential 30 ha public) • 11.800 new flats (45% rented), 40 – 120kvm • 290.000 m2 new offices, schools, shops, services • 25.000 inhabitants and 10.000 jobs
• huge infrastructure projects – railway, tunnels, district heating, broadband • investments 3 billions Euros, the cities part 15% • construction time 1995-2017. Today 70% finished
Facts on Housing •Most sites owned by the city and leased •Density (e) 1.43 incl public space (2.2-3.0 excl) •Heights of buildings – average 18 m (12-24 m) •46% rented apartments 54% owned in associations •Apartment sizes from 40 sqm to 120 sqm – average 75 sqm (two bedrooms). •75 sqm: Rent 1400 €/m Price 350,000 € + 300 €/m fea •33 developers and 29 architect firms (so far)

The ”Hammarby” ecocycle model Energy Heat and Electricity
Waste Recycle, energy and fertilizer and biogas
Water Rain locally treated Sewage = cleaned+ biogas, heat and fertilizer
General goal for the project The environment by emissions shall be 50 % lower than new housing areas from the early 1990s. Result today: about 30-40%
Green planning 25 sqm free space per apartment •All green space in connection through the area – green corridors •1.000 new trees and all lawns are new •Always into consideration of existing landscape
Every block has its individualy designed garden
Green paths all along
Water treatment •Storm water from the blocks is collected and let out into the lake locally •Storm water from roads is treated in baisins locally •Water from households treated in the waste water plant - sludge to biogas and fertilizer
A channel for Stormwater reflecting the sky
Green roof collecting rain
Waste •Waste separation – organic, combustable, newspaper from inlets in each courtyard •Waste vacuum system to reduce traffic and labour •Metal, glass, packages and hazardous in wasterooms inside every house •No landfill from waste – all recycled
Inlets for the 3 largest fractions of waste
Vacuum waste system reduses waste transports 80%
Pipes for waste transports under the ground
Energy •Combustible waste to district heating and electricity – combined heat and power •Biogas from waste water – to busses and cookers •Heat from treated wastewater into district heating and cooling •Solar cells, solar panels and fuel cell •50% of energy need out of local sources
District Heat in Stockholm Heat production 9 TWh District cooling 0.4 TWh Electricity 1,6 TWh
WtE CHP Plant
Fortum Fuel Mix Fossil fuels 21%
Bio fuels 33%
Waste to Energy 28% Seawater, Free cooling and Waste water 18%
