2026: Roadmapper Bygg - decision support for the built environment

This half-year pre-study started in January 2026 and aim to investigate about decision support for the built environment. It was lead by the SustainTrans team: Henrik Ny, Sven Borén and Lisa Wälitalo and supported financially by Tillväxtverket and BTH

Different life-cycle steps for a building

The Roadmapper Bygg feasibility study aimed to lay the foundation for an implementation project that will develop strategic decision support to accelerate the transition to a circular and sustainable construction and real estate sector. The project has focused on identifying target groups, mapping their needs and challenges, and developing and testing concepts for decision functionality.The work included two workshops and complementary interviews with actors from the construction sector, municipalities, regions, authorities and networks. Workshop 1 mapped challenges and necessary shifts in the sector, where participants raised obstacles such as economic drivers that counteract sustainability, unclear regulations, inadequate material logistics and traditional working methods. The needs picture shows that actors are demanding clearer requirements, better knowledge, common goals and support to understand the consequences of different choices. Workshop 2 focused on defining and proposing decision support, which includes, among other things...

(1)...free advice for SMEs,

(2)...knowledge databases,

(3)...training initiatives,

(4)...function-based community planning,

(5)...digital portals for recycling and

(6)...development of economic models and regulations that promote circularity.

The interviews confirmed the relevance and provided in-depth views, e.g. the need for life cycle cost analyses, clearer requirements formulations and support for risk sharing in recycling.
The feasibility study showed that a future implementation project should develop a digital decision support integrated into the Roadmapper Bygg platform, with a focus on strategic decisions for SMEs and local community planning. The project should also specify the decision support needs, co-development of strategic decision support and decision support for community planning together with the target groups, integration into Roadmapper Bygg, pilot projects, knowledge transfer and establishment of long-term collaboration structures. The implementation is assessed to be able to strengthen the competitiveness of SMEs, increase circularity in the sector and contribute to several of the UN's global sustainability goals.
