Outcomes of the project

The following publications have been produced in the project:

• Additional dwelling units: Can they finance energy renovation?
• Comparing public- and private-driven one-stop-shops for energy renovations of residential buildings in Europe
• Strategies for deep renovation market of detached houses
• Energieffektiviseringsåtgärder av småhus: Guide för entreprenörer som vill ta ett helhetsansvar (pdf file)

• Kundresa för one-stop-shop (pdf file)

More about the project

Energy-efficient renovation has been identified as an important goal of the United Nations Urban Development Agenda to drive the development of sustainable cities. At the same time, the European Commission's Energy Performance of Buildings Directive (EPBD) has identified "one-stop-shops" (OSS) as a useful means to stimulate extensive renovations.

There is a large interest in the OSS concept among both homeowners and small and medium entrepreneurs (SMEs), which dominate the renovation market. However, past studies have shown that SMEs are hesitant to offer OSS service, mainly due to the lack of competency and resources to manage and coordinate multiple actors, insecurity about quality of work by other companies, and, above all, the perceived business risks.

This project will adopt the transdisciplinary approach, which will integrate both scientific knowledge and societal knowledge to co-create the solution-oriented knowledge. The proposed project will focus on two areas for the solutions viz.

1. Capacity building of various actors within the value chain, and
2. Developing a strategy for the municipality for deep renovation of detached houses.

The project will be instrumental in translating the gained scientific knowledge from the following two research projects into practice, for increased energy renovation of detached houses in Sweden:

• One-stop-shop business model for energy renovation of detached houses (financed by the Kamprad Family Foundation)
• Integrated solutions for ambitious energy refurbishment of private housing (INNOVATE) (financed under EU Horizon 2020)

The scientific knowledge from Linnaeus University and RISE will be blended with the knowledge and expertise from societal partners (Växjö municipality, the Energy Agency for Southeast Sweden and Villaägarna Kronoberg) to translate the research findings in meaningful practices.

Overall goal

This project will help in meeting the national as well as Växjö municipality's goals regarding energy efficiency and GHG emission reduction from the residential sector. The main objectives of the project are:

• Capacity building of the supply-side actors (artisans, installation companies, consultants, architects, etc) and homeowners.
• Recommend strategies and pathways for Växjö municipality for the deep renovation of the detached houses.

The project is part of the research conducted by the Sustainable Built Environment Research (SBER) research group.
