According to the Dutch Building Regulations for new construction and renovation, every radiator in the Netherlands must be equipped with a thermostatic radiator valve with the possibility to set the design flow to increase energy efficiency.
The Dutch Housing Associations play an important role in making Dutch housing stock more sustainable. The challenge for them is to protect the public interest within the framework of the new legislation by providing affordable, durable and reliable heat supply for tenants.
The new Dutch legislation focuses on dimensioning, installation, adjustment, and usability. This is due to research which has shown that modern installations that were supposed to contribute to lower energy consumption were by no means fully utilised. In these same installations, consumption could be reduced by up to 30 percent with the correct integrated approach.
The result will be closer cooperation between building owners and installation professionals.
Everything is aimed at optimising the existing installation in preparation for a new sustainable heat source. Attention is also paid to the controllability by the end-user so that they have more control over their own consumption. Temperature control per room and the adjustment of installations provide more comfort and pave the way for new heating devices that use no or less gas.
The new requirements have direct and indirect consequences for housing associations. Over the next four years, housing corporations will contribute to disconnecting 100 000 homes free of natural gas.
The new legislation hereby puts focus on the entire installation, not just the part that needs to be replaced.
Direct consequences are the requirements to install radiator thermostats and hydronic commissioning of the system when, for example, the boilers are replaced by district heating units or heat pumps.
Indirect consequences are higher requirements for professional competence and extra time spent by installers.
The Danfoss team in the Netherlands supports installation companies and consultants with expertise in hydronic balancing and help make the right choices in the face of the new laws and regulations.
We believe that information should be free and will therefore never put up a paywall.
