Step by Step.

In late February 2019, the Welvreugd/Hamer joint venture was contracted to install the pipes and pumps for the hot-and-cold transfer system. This was followed by the inevitable slew of permit applications, until the excavation work and directional drillings could finally get underway in May 2019. We had to work around two privately owned plots of land housing local businesses: Burgers Carrosserie (auto body repair shop) and Bakkerij van Muyden (bakery). The long-term lease for this land was issued in early May. At this point, the installations at the site of the partners involved in the hot-and-cold transfer project were being prepped for operation, the final step being a test that involved circulating the initial water produced through the system. Actual installation and commissioning at the De Waterlelie swimming pool and sports center and Triade school/day care center were scheduled for September, followed by the work performed at Fertiplant in October/November.

In April 2016, the City of Aalsmeer, NorthC Datacenters, ESA Aalsmeer (which operates the De Waterlelie swimming pool and sports center), and the JongLeren and Solidoe nonprofits signed a partnership agreement to formalize their long-term alliance. The success of any project depends entirely on a detailed project plan. With Nederland ICT acting as a broker, the consortium received financial support from the Netherlands Enterprise Agency to conduct an impact and feasibility study. Key components include the business base and a detailed risk analysis. The central question, of course, is: how much does it cost and how will it benefit us? In the fall of 2016, Fertiplant, a local trading company specializing in potted plants, joined the project – another partner dedicated to ensuring a sustainable future. The construction of the Triade child center also began this year. With an eye on the future, they incorporated a connection of the innovative hot-and-cold transfer into the construction process.

The City of Aalsmeer is looking for the most sustainable energy supply for its Hornmeer district, where a number of changes are anticipated, including the construction of a school/day care center, a sports center, and new homes. The existing environment (mainly homes, businesses and the local swimming pool) will eventually also need to run on renewable energy. Infinitus Energy Solutions Group explored this issue with various market players and investigated a combination of the use of sustainable energy and energy-efficiency. This resulted in initial talks for a sustainable heat transfer process in Hornmeer with appropriate partners, who shared the same ideas about sustainability.
