Embedding circularity at the core of the planning and decision-making process. Circularity must be there from the start since it can be difficult to integrate it later. This means considering not only recycled materials or reused building products, but also how best to meet demand with existing structures through renovation and modification while considering multi-use projects which can fulfil multiple needs with one building (Steen, 2022) (Höjer, 2022) (Lunneblad, 2022) (Laurikainen, 2022) (Brix, 2022) (Jacobsson, 2022).
Promoting designs targeting flexibility, adaptability, and disassembly. Buildings should be able to be extended, moved, deconstructed, and converted into a new building. This means ensuring that the buildings we build now will not be torn down in thirty years but can be adapted to address a new demand and fulfil a new function. This maintains the value of the building stock and ensures that they have a longer useful life (Kilvær, 2022).
Focusing on better management of existing building renovations. The best building for the environment is the one that is not built at all. At the planning stage, there must be stronger focus on how existing buildings can be transformed to fulfil a new function or updated to modern standards (Eriksson, 2022) (Kilvær, 2022) (Kjerulf, 2022) (Koch-Ørvad, 2022) (Wærner, 2022) (Lahtinen, 2022).
Using Green Public Procurement to drive demand for circularity in construction projects. This could be achieved by making the reuse and recycling of materials an obligatory component for public procurement of construction services (Runge, 2022) (Wennerholm, 2022). This can include adopting innovative public procurement processes. For example, the city of Gothenburg engages in market dialogue by inviting selected actors to address long-term challenges that are not yet suitable for specific procurement calls. This means that the city helps support the development of product and services that it may require, without committing to a purchase (Jacobsson, 2022).
Establishing public-private partnerships can help minimise many of the barriers experienced by stakeholders since responsibility and economic risk can be spread more widely (Kilvær, 2022).
Improving cooperation between public departments. Several stakeholders mentioned the need for better cooperation and coordination between public departments and agencies (Dahlgren, 2022).
Expanding consequence analysis in order to include soft factors and move beyond CO2.
Using multidisciplinary, multi-faceted design teams (architects, engineers, sustainability specialists, trades). Many people who work with reuse are environmental consultants and not civil engineers. To understand the performance of constructions and better map construction products, an interdisciplinary team is needed (Wærner, 2022).
Better and earlier communication throughout the value chain and between project team members. Architects, consult engineers, contractors, and the client/developer need to communicate earlier in the process and throughout the entire value chain (Steen, 2022) (Brix, 2022).
Synchronising timelines for different building projects would allow materials to more easily be extracted from one project and used directly in another, thus avoiding the environmental and economic impacts from the intervening storage and transport (Bjarnadóttir, 2022).
