Hilda Housing Project, Malmö

WSP has been working with the 2,500 residents of the 1960s Hilda Housing Cooperative in Rosengård, Malmö, to retrofit their homes not only to dramatically improve their energy efficiency, but to enable them to be energy self-sufficient within 10 years.

Immediate measures include fitting new pipes for hot and cold water and sewage disposal, implementing water metering for each flat, and installing the infrastructure to collect household waste for biogas production. 

The building facades will receive an extra layer of insulation, and each flat will be installed with new energy-saving radiators and a ventilation system that reuses heated indoor air.

Outside, solar panels and collectors will provide electricity and hot water, low-rise buildings will be clad with green roofs and rainwater harvesting will be introduced.

Sustainable transport initiatives include an electric bicycle pool and real-time display of bus and train service information in the stairwells, and more pleasant and green spaces surrounding them.

WSP is also working for the Swedish Energy Agency to develop cost-effective solutions that can be rolled out much more widely across the Million Programme homes – a Swedish Government programme from 1965 to build 1 million new homes within 10 years.

As the 850,000 flats and 150,000 family houses built under the programme account for such a substantial proportion of Sweden’s domestic buildings, they are a major contributor to its carbon dioxide emissions. The aim is to reduce the energy needs of these homes by 50%.
