The “Hedebygade” building block is situated at Vesterbro in Copenhagen and it comprises 350 apartments from around 1888. There are different forms of ownership such as housing society tenancies, private tenancies and owner-occupied flats.

The block of flats has gone through a comprehensive restoration, which was completed at the turn of the year 2001/2002. The project comprises 12 subprojects, which in combination are intended to demonstrate a catalogue of urban ecology solutions.

The projects have been carried out in close cooperation between residents, owners, consultants and the urban renewal company SBS Byfornyelse.

Since the project was launched in 1998, the tenants have emphasised the importance of resource saving solutions. The project seeks to optimise the consumption of heating, hot water, and electricity through the use of new energy saving technology. Secondary aims are lessening water usage and ensuring good indoor climate. It was the aim to reduce the energy use for heating and domestic hot water by 50-60%, and at the same time obtain 20-40% savings on electricity and water use. These figures are compared to the situation before the renovation. In a broader perspective, the city of Copenhagen can use the results to define improved energy and environmental standards e.g. as part of Copenhagen CO2 saving plans for 2000-2005.

It was the general goal to make an architectural well-integrated energy efficient overall solution for multi storey buildings that takes care of the indoor air climate and comfort level for the tenants, and at the same time obtains reasonable energy savings together with the use of renewable energy.

The Hedebygade project has incorporated various low energy technologies, and they clearly illustrate the benefits of integrated solutions::

• Building integrated solar energy
• Combined system for ventilation, space heating, and hot water
• Solar cells on south-facing wall
• Flexible facades with solar energy
• Natural lighting
• Consumption metering
• Waste sorting
• Air purification with living plants
• Community house
• Communal grounds
• Green Kitchen
