The Adoption of Green Modular Innovations in the Dutch Housebuilding Sector

Why a good module is not enough

In this article, we examined what makes green modular innovation actually take hold in Dutch housebuilding. The sector is being asked to respond at once to housing shortages, carbon reduction, energy renovation, labour constraints and circular construction. Modular systems can help: factory production can improve quality and efficiency, standard interfaces can allow customisation, and components may be repaired, upgraded or reused. But those advantages do not guarantee that a system will be chosen in a real project.

We studied three quite different innovations: a modular renewable-energy system, a prefabricated bathroom pod and a building-integrated photovoltaic roof. Looking across these cases helped us move beyond the features of one product. Adoption is a project decision made within a network of clients, builders, suppliers, designers, regulators and users. Technical performance matters, but so do responsibilities, planning, logistics and the ability of all those actors to work together.

Designing the route into a project

Our analysis identified ten connected variables and four pathways through which green modular innovations can become viable. The same idea may be adopted in one project and rejected in another because product modularity, process modularity and supply-chain modularity have to align. A component needs to do more than function by itself; it must fit existing interfaces, production routines, delivery systems and expectations across the project.

Standardised, decoupled interfaces can create real benefits. They can make subsystems easier to upgrade independently and support refurbishment, reuse and recycling. Off-site production can improve safety, productivity and quality control while reducing waste. Yet modularity also asks for early coordination. Common design rules and interfaces may require intensive collaboration before a wider supplier network can participate.

Our main conclusion is practical: environmental benefit or policy pressure alone does not drive adoption. Green modular innovation succeeds when value is clear, interfaces are compatible, the supply chain can deliver and project partners can coordinate around the needs of a particular housing context. For managers, that means designing both the module and its route into the project. For policymakers, it means supporting organisational conditions as well as the technology.
