Björn Emil Härtel JensenCity Planner and Project Manager
The capital region – the main force for growth
1,8 mill. inhabitants, which corresponds to 1/3 of Denmark's population.
§ Home for more than half of the Danish population with more extensive education.
§ 75 % of all new jobs in Denmark.§ 80 % of high tech businesses.§ 70 % of all private and public
science and development.§ 85 % of foreign investments.
Albertslund – a young city
One of several small municipalities west of Copenhagen with 30,000 residents.
A new and modern city, part of the building boom of the 1960s, planned by the experimental principles of urban and traffic planning of that time.
A thinly populated area was transformed into a laboratory for urban development, democracy, and industrial building.
In Albertslund innovative council houses popped up, rapidly constructed and using new materials.
Albertslund – in numbers
• Population: 27.706
• 26 % of the population have another ethnic background than Danish.
• Size: 23 Square km
• 61 % of all dwellings are social housing owned and managed by non-profit housing company
Albertslund – a young city of many qualities
Located close to green areas, close to Copenhagen and Roskilde, close to commuter train.
An open city centre and cultural scene with public library, theatre, and music venue.
Division of roads and paths between ’hard’ and ’soft’ road-users.
Key issues Children, culture and environment.
An anchored environmental effort together with citizens, business communities, and employees through environmental certification and measurements.
Holistic approach to creating a sustainable Albertslund
• Transport • Energy and Climate • Social Sustainability• Urban Densification• Urban Structure• Cultural Heritage and Identity • Participation

Traffic separation, example 1 (Hyldespjældet)
Traffic separation, example 1 (Hyldespjældet)
• No car access• No noise and
polution from cars• Safe and secure
spaces for children to play
Bicycle Strategy Albertslund
• Strategy adopted by the politicians, spring 2009
• Target = 10% more cyclists from 2009-2015
• But how?
How to achieve the goal?
• 44 different strategy points• Based on 3 important efforts
1. It has to be easy and fast to get around on the cycle paths (direct routes)
2. There has to be a good accessibility to schools, shopping and all other important functions (no missing links)
3. The cyclist must feel safe when getting around (lights, signs)
Cycle path connections
Cycle path’s appearance
• Feeling Safe• Signs – find your way• Barriers
Comfort and maintenance
• Tunnel• Cover• Snow, ice, leaves etc.
Cycle culture (behavior)
• Educating children• Mopeds• Intersections

How we meet the climate change
LOCAL AUTHORITY
BUILDINGS LIGHTING TRANSPORT
Activities
1. Climate-friendly use of buildings. New institutions as passive houses. CO2 neutral culture and sports facility. Energy-renovation of institutions.
2. Lighting of the future.
3. Greener transport.
LOCAL AUTHORITY – MUNICIPAL BUILDINGS- Institutions of the future occupy passive houses
New day-care institutions – for the new renovated city
ChallengesMost buildings were built in the period 1965 – 1980.
Experiments were carried out with fast and new types of construction, mass production of element building.
Objectives for municipal buildingsArchitecture of high standard creates optimal frames for visionary learning environments and healthy places for leisure and work.
Buildings in the absolute front concerning energy and environment.
New institutions – new options
Part of an overall plan for day-care institutions covering both renovation and new building.
Nursery and kindergarten each having 100 children. Benchmarks in three local communities in the city – south, central, north. First children started in December 2010.
Varying rooms indoors and outdoors for all-round playing, challenging fantasy and muscular activity.
New passiv house institutions - efficient energy measures
Location of houses ensuring best possible utilisation of passive solar heating in winter.
Heavy construction elements heat the building in winter and cool it in summer.
Compact building mass reduces energy loss through highly insulated windows, roof, walls.
Dense building, mechanical ventilation and heat recovery.
Pre-heated air from underground channels and solar collectors for heating of supply water.
15 kWh/m² per year
New institutions – also a climate benefit
The new buildings combine respect for function, architecture and environment and are frontrunners within sustainability regarding energy and environment.

HOUSING
RENOVATION NEW BEHAVIOR BUILDINGS
Activities
1. Climate renovation of residential areas. 2. Sustainable housing in the city centre. 3. Climate aware behavior
HOUSING – CLIMATE FRIENDLY RENOVATION- Holistic modernisation and climate renovation of
the City’s housing areas
16 housing areas - 35% of all dwellings and 38% of the CO2 emission from dwellings.
Renovation of the 16 housing areas to energy class 2 will mean a 21% reduction or 3.700 tonnes CO2.
Renovation of the 16 housing areas to energy class 1 will mean a 24% reduction or 4.400 tonnes CO2.
Challenges and opportunities
Renovation of 16 housing areas covering 35% the City’s dwellings - a unique chance of modernising the City in a climate-friendly manner.
Additional financing is raised to attain attractive energy classes through the Energy Technology Development and Demonstration Programme (EUDP).
Need for solutions being:• Green and cost-effective• Market-oriented• Architecturally and socially aware• An asset in urban conversion• Holistic in terms of know-how• Generator of expertise
Public private partnerships -The case of Masterplan Syd
•Cooperation between the municipality and the housing company BO VEST. •Projects amounting to 3 billion DKK / 44 billion Yen
A Public Housing Company in Denmark
Public housing is divided in departments of housing companies. Each company is a separate economic entity and is governed by a board, elected by the dwellers at a annual general meeting. The board has the supreme power in matters of renovation and a renovation can’t be implemented without their approval.
Albertslund Concept – climate friendly renovation 1
In Albertslund South alone 2,200 dwellings are being renovated, housing almost 6,000 people.
As a demonstration project a block of six attached houses will be renovated into different energy classes - Up to energy class 1, with the same or better economy than energy class 2.
Energy class 2 will result in a reduction in energy consumption of 73%.
Functional dwellings of high architectural value with focus on indoor climate, healthy materials, daylight and comfort.
Public private partnerships – the Albertslund Concept
Clarifying how the extensive task concerning energy renovation of residential areas established after 1960 can be solved in technical and financial terms.
Bringing the new renovated residential areas up to the same energy-efficient standard as new and modern houses.
The Albertslund Concept will demonstrate that cost-efficient low-energy renovation of dwellings is feasible by gathering all relevant actors and knowledge within energy and construction.
The housing company BO VEST is planning the renovation project. Raising renting costs are decided by the residents. Budgets are decided in Landsbyggefonden, where energy improvements are not supported. They are considered to be improvement that have to be paid by the resident. Put on top of the raise in rent, caused by the general renovation.
HOUSING – CLIMATE FRIENDLY RENOVATION- Holistic modernisation and climate renovation of the City’s
