Hermitage Amsterdam and Hortus Botanicus Amsterdam will start sharing renewable heat and cooling. Source is the Hermitage Amsterdam’s thermal energy storage for the heating and cooling of the exhibition halls. Heat that the Hortus Botanicus can use for the heating of the monumental greenhouses. The garden returns cooled water to the Hermitage for the museum’s air conditioning system.
On June 30, a 425 meter long underground connection between the Hermitage Amsterdam and the Hortus Botanicus was successfully completed. The construction of the underground link is part of the progressive sustainability project “between Art and Greenhouse”, where the Hermitage Amsterdam and the Hortus Botanicus share their surplus heat and cold, with large energy-saving results.
As of this year, both National monuments will be forever linked.

The pioneering innovations were presented of the Scale Up Future-proof artificial turf pitches project, a collaboration between Amsterdam and Haarlem focused on sustainable artificial turf pitches. Over the next few years, more than 250 sports pitches in both cities will be transformed into circular, energy-generating and climate-adaptive sports venues. These artificial turf pitches can not only generate and store energy, but also involve smart water management. An approach that is globally relevant for urban sports infrastructure.
Three consortia collaborate on the sport pitch of the future
The three selected consortia Antea Sport, EnergieVeld and GOO4iT together comprise more than 15 market players. They join forces within this innovation partnership, where there is room for long-term collaboration, co-creation and scalable innovation. The pioneering solutions will make it possible to cool down sport pitches on warm days, help dispose of and collect rainwater, make the pitches more pleasant for the users and possibly even generate energy for the surrounding area. Find out how these innovations are shaping the sport pitch of the future here.
Two municipalities: joint procurement
The Scale Up Future-proof artificial turf pitches project is a unique collaboration between two municipalities and market players. The municipalities jointly procure pooling their purchasing power and use an innovation partnership to challenge the market to test and scale up innovative and sustainable solutions. In doing so, the solutions are also scalable and transferable to other cities in the Netherlands and Europe.
From prototype to pilot fields
The first prototype fields will be constructed in Amsterdam and Haarlem in 2026, in different capacities and combining multiple innovations, where they will be extensively tested and monitored for a year. Successful concepts are then scaled up to full-scale pilot pitches and tested and monitored for another year. This will form the basis for the new standard of sustainable sports pitches, with potential for adoption in other cities around the world. At the same time, existing pitches are already being improved with the most sustainable solutions available, making an immediate impact from the start. The project thus shows how cooperation between municipalities and market players can lead to innovative, climate-proof sports infrastructure with international relevance.

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

The municipality of Haarlemmermeer is actively working on the realisation of the energy transition in the municipality by, among other things, focusing on sustainable heat supplies. As part of this, a heat initiative has been started in the village of Rijsenhout (east of Haarlemmermeer). This initiative has not been taken up by the market in the past. This has led the municipality to want to take a more active role in the development of District heating in which resident participation is a crucial factor.
During the Knowledge- and Demodag on 13th of March (2025), Kelly Winters and Sophie Keijzer (Hieroo) led a session with the participants that looked at similar successful processes in the past of realising a heat network. The central questions were: What was the success and why was it a success?
Session structure and focus
During the session, the participants split into two groups. Similar processes were then discussed in the two groups in which the success factors of the realisation of energy transition projects were examined. An important example that was discussed in the session was the Schoonschip project in Amsterdam North. This project is a sustainable initiative in which residents have researched how they can live on the water in a circular and sustainable way. This resulted in a community of 46 houseboats that share energy with each other via a Smart Grid that’s cheaper and more efficient.
Outcomes and insights
During the session, various strategies were discussed to strengthen resident participation and make heat network initiatives successful. The most important points from the discussions are:
1. Composition of the initiator group: A diverse and enthusiastic group is crucial. In the Schoonschip project, the core of the success was a group of pioneers who complemented each other in creativity and expertise. Such a group can also be formed in Rijsenhout if they are properly guided and supported.
2. The role of the municipality: The municipality must be aware of the distrust that residents often have towards government institutions. Using an external intermediary or an independent entity can help to reduce this mistrust.
3. Reward and inspire: One way to involve residents in a low-interest topic such as energy is to reward them. Examples are setting up competitions, the use of ambassadors or energy coaches and the organisation of events. Linking opportunities, for example by combining energy transition with social goals such as combating energy poverty, can also play an important role.
4. Using the right moment: An important lesson from the Schoonschip project is to use external circumstances to arouse interest. A crisis, such as rising energy costs or limited energy production, can turn a low interest topic into a high interest topic for people.
5. Governance and structure: A solid Governance structure is essential. The municipality can play a role as a project manager by setting clear deadlines and formulating requirements. This helps both initiators and residents to keep focus and take steps towards concrete results.
