Games for Cities international conference

On June 12th 2025 we will celebrate the 7th edition of the international Outdoor Office Day. It’s an open invitation to take your work outside, reconnect with the surrounding urban nature around your office.

This year’s theme is 'Connecting with each other’: with your direct colleagues, colleagues from other departments, neighbours, or external relations. Please join the growing network of individuals and companies that take their work outside more and more often. Get inspired whilst you spend time surrounded by urban nature. This enhances new and meaningful relationships, stimulates the flow of good ideas and supports the forging of valuable collaborations.

Please meet our partners and participants:

If in Amsterdam we invite for wanderwalk with sustainable leaders. Join us in Amsterdamse Bos to discuss your dilemma's, learn from each other and connect.

How do you install district heating in villages with narrow streets and limited underground space? This was the central question during a recent deepdive session hosted in the municipality of Haarlemmermeer. The session brought together experts from the City of Amsterdam, local officials and experts from Haarlemmermeer, and Arcadis to explore practical solutions to the physical challenges of implementing district heating in dense and complex infrastructure environments.

From complexity to coordination

Amsterdam has years of experience addressing similar challenges in dense urban areas where underground infrastructure is already under pressure. Experts from the City of Amsterdam were invited to share their approach, which combines long-term planning, integrated design processes, and flexibility in applying standards.

Some key principles they shared:

• Planning 15 years ahead: Amsterdam actively involves all utility providers to map out future plans and co-create underground infrastructure layouts.
• Using standard ways of working in the underground (WIOR) and a standardised scheme for subsurface infrastructure planning: These frameworks help assess available underground space and guide decisions when concessions are necessary.
• Embracing alternative methods: Stacking pipelines instead of placing them side-by-side, drilling under roads, or clustering transport cables in walls or consolidated zones are all viable options.

Sometimes, this requires deviating from standard spacing requirements. Such exceptions are only made with strong justification and agreement at the decision-making level.

A fresh look at Haarlemmermeer’s challenges

Participants from Haarlemmermeer acknowledged that they face several pressing issues. With limited space in the underground and a lack of an integrated planning framework, it is difficult to make informed, long-term decisions. Three villages in the municipality are particularly challenging due to their narrow streets and aging infrastructure.

Key challenges included:

• Underestimating the space needed for district heating infrastructure (including expansion loops, communication lines, and insulation).
• Rigid adherence to guidelines, which may not always be feasible locally.
• A missing coordinating role to oversee all the different parties operating in the underground to facilitate collaboration.

Shared lessons, shared responsibility

The session made clear that while every context is different, the challenges of underground infrastructure for district heating are shared across municipalities. The city of Amsterdam is a bit further ahead than Haarlemmermeer, and their expertise was already tremendously helpful. The Amsterdam case shows that smart, flexible planning—backed by clear coordination of all parties active in the underground —can lead to effective, long-term solutions.

Now the task for Haarlemmermeer is to translate these insights into concrete next steps. As one participant concluded, “We need to move from awareness to action.”

This Wednesday we'll be tinkering in the Makerspace of the OBA again, you can work on your own projects but you can also join the free workshop where you can learn to run an AI model locally on your smartphone or microcontroller and teach it to do keyword spotting or object recognition.
Looking forward to seeing you! We spreken trouwens ook Nederlands!
