Optimal lighting comfort at Rijkskantoor De Knoop

The Central Government Real Estate Agency has transformed the former Lieutenant General Knoop Barracks into a modern government office where various government services have taken up residence. Part of the old building has been demolished and the remaining parts have undergone a large-scale transformation. Consortium R Creators – consisting of consortium partners Strukton, Ballast Nedam and Facilicom – has realized the redevelopment, and Helvar lighting controls have been installed on the site.


Helvar has realized the light management system on behalf of R Creators. The light management system offers energy savings and optimum comfort for the users of the building. All rooms are equipped with presence and absence sensors. In addition, the light management system is integrated with the building management system via a BACnet link.

This means that the information from the motion sensors can also be used to switch on ventilation, heating or cooling. It can also be determined on the basis of presence detection which rooms have been used in a certain period. The flexibility of a DALI network system ensures that the lighting can always be easily adjusted without the need for adjustments in the installation.


Service and Maintenance

This government office was commissioned within a Design, Build, Finance, Maintain & Operate (DBFMO) contract. This means that R Creators is responsible for the management and maintenance of the building for 20 years after completion. Service and maintenance were therefore important topics during the awarding process. Helvar provides this by means of an online service in which faults and other defects in the emergency lighting are automatically reported to the operator on-site. As a result, the time that a room is out of order is minimized, faults are resolved prematurely and maximum comfort is offered to the user.
