Sustainable Homes

The KTH Centre for a Sustainable Built Environment has initiated the research environment Sustainable Homes to meet both large and small challenges of housing.

The goal of the Sustainable Homes focus area is to initiate, develop and operate a cross-disciplinary housing research environment at KTH complemented external networks to build knowledge, achieve solutions and contribute to sustainable development, particularly in the Stockholm region. The ambition is that Sustainable Homes will define and answer questions from all actors and stakeholders in the quadruple helix model - public sector, industry, academia and civil society - that influences the development of housing stock. Within five years Sustainable Homes aims to be an obvious and knowledge-building partner when homes are discussed, controlled, analyzed, financed, designed, constructed, equipped, reconditioned, developed, and inhabited in order to build a more sustainable and less segregated society.

The challenges for Stockholm are clear. First, Stockholm's population is rapidly increasing creating an acute housing shortage. The Stockholm region's population is expected to increase from the current 2.2 million to 2.7 million in 2030 and 3.0 million by 2045. The county is therefore planning to build 140,000 apartments by 2030. During the period 2001 to 2012 just under 11,000 homes in the county were converted to permanent residency (primarily vacation homes that became year-round homes) illustrating another way by which this shortage is being addressed.

Second, segregation is increasing dramatically in the existing housing stock of Stockholm (numbering over one million dwellings). Above all, economic segregation is increasing between housing groups, between neighborhoods and between municipalities.

Third, many existing homes need to be renovated. In particular some 200,000 homes built during the 1950's and 1960's, the so-called "Million Program Era", require rennovation. Rennovating these buildings whilst also building new homes will place considerable stress on Stockholm's building sector's capacity.

With experience from Green Boost, a pilot study financed by the European Regional Structural Fund, a method for how these challenges can be met has been developed. We call the method Green Bo+Stad.
