The National Sustainable House Route is an initiative encouraging homeowners to share energy-saving measures, such as cavity wall insulation, underfloor heating, or ventilation systems. Participants can register their homes on a national platform to create profiles where others can learn from their experiences.

In addition to the digital platform, the program includes national open house days scheduled for October 31 and November 7. During these events, homeowners will showcase their energy-efficient upgrades in person. The initiative has seen participation from more than 2,500 people and is supported by the Ministry of Housing and Spatial Planning, the province of Gelderland, and over 100 municipalities.
