Integrated system roadmap towards a climate-neutral built environment (INTERTWINE)

To contribute to the creation of roadmaps for climate-neutral urban built environments, we investigate how subsystems of construction, energy distribution, and transportation interact.

As cities grow, construction activities and their associated transport intensify, increasing energy demand and transport emissions. Different systems operate with different planning horizons and priorities. Construction sites require energy quickly and on a temporary basis. At the same time, electricity grid operators plan on a five- to ten-year horizon, while logistics companies operate in cycles of two to three years. This temporal mismatch creates bottlenecks, uncertainty, and pressure on local actors to find their own solutions.

Thus, despite the existence of technology and vehicles, the development of charging solutions, and the strong interconnections between the subsystems for construction, energy distribution, and transport, the electrification of heavy transport and construction logistics is progressing slowly. Why is this the case?

The answer lies in a lack of coordination between these subsystems. The barriers are primarily not technical, but organizational, institutional, and related to the inherent mechanisms of the systems themselves. The transition of heavy transport cannot be seen as a simple vehicle replacement—it requires thorough coordination between the energy system, the transport system, and the built environment.

Workshops and dialogues with industry and the public sector confirm this picture of misaligned subsystems and the obstacles to collaboration.

Three key challenges

Lack of coordination in implementation
There are no clear models for how grid capacity, charging infrastructure, and construction processes should be coordinated in practice.

Unclear responsibilities and power structures
Unequal access to electricity grid capacity, capital, and land can act as “veto points” that slow down electrification.

Lack of a shared vision
Municipalities, energy companies, transport firms, and property owners interpret the transition differently, which complicates investments and long-term planning.

Developing energy logistics

The project shows that we need to develop what is referred to as “energy logistics” — a new way of coordinating grid planning, energy management, and freight and construction logistics. Through improved capacity planning, shared infrastructure, and clearer rules of the game, electrification can be scaled up while also strengthening the robustness of the electricity system.

The starting point of the project was a clear knowledge gap regarding how these systems are interconnected. The next step involves deepening research on energy prioritization and charging optimization, actor roles and energy communities, as well as policy and system transformation with a focus on logistics and industrial properties.
