'We determined the technical frameworks together with the consultant'

Mechanical installation, plumbing installation, control technology and heat/cold sources

Klimaatservice Holland is providing the entire mechanical installation, sanitary installation and heat/cold sources for the Aan het Water project in Amsterdam. The company is also taking care of the ventilation of the parking garage, firefighting and control technology.

It is a substantial project with a flexible floor area of some 13,500 m2. The offices will be delivered as shells, allowing tenants to fill them in at a later date. In addition to the office space, there will be a three-level parking garage for visitors and employees and a commercial space on the first floor. Pieter Meerkerk is project manager at Klimaatservice Holland: "The building is being developed sustainably, with the ambition of receiving the 'Very Good' BREEAM certificate upon completion," he says. "We became involved in the project at an early stage and were allowed to determine the technical frameworks together with the client and consultant." 

Mono sources and risk diversification

Even before construction began about a year and a half ago, heat/cold wells were drilled. The building features two towers that are connected on the lower floors. Each tower has its own heat/cold source and technical installation. These installations are connected to each other, however, so that in an emergency one installation can support the other. Says Meerkerk, "The use of two WKO systems with two vertical sources to spread the risk does make this project special. In this case we are talking about two mono sources. The advantage of a mono source is that it only needs to be drilled once. In operation, there is no difference from a doublet system. A heat pump is placed on the roof of each tower as a back-up, as well as an electric boiler for emergency or peak situations. It must be strange if no heat or cold can be taken from the building."

Full steam ahead

Right now, Klimaatservice Holland BV is still working off and on to install the sanitary pouring facilities in the lower floors. By the end of this year, the towers will be structurally at height. During the summer, the WKO sources will be developed. "Since June we have been working full time and the peak for us is in the last quarter of 2023 and early 2024. In May 2024, we hope to deliver the building."
