Project summary
Energy company REMU (now ENECO) and the municipality of Houten have realized a new fire department building, which was designed by the leading Belgian architect Philip Samyn. It can be viewed as a building inside a building: 3 blocks of offices are gradually placed upon each other. All of this is covered by a parabolic-shaped roofing. This provides space for six fire trucks. With its climate roof, the hangar is a buffer zone between inside and outside. One side of the roofing is provided with a 400-m², transparent solar pv system. Solar power has been included in the design since the start. This has resulted in an optimal orientation relative to the sun. The municipality and REMU want to use the project to promote ‘renewable construction’ in general and solar power in specific. It is the first segmented solar pv façade in the Netherlands in which transparent panels are used to make up the covering.

Best practice project
Because of the contribution by 2200 elementary school children, who painted 2200 A4-sized panels that are being displayed in the hangar, the application of solar power gets even more attention. This clearly lowered the threshold, and as a result of this the involvement of the inhabitants of Houten is notably great.

Special PV project info
PV architecture and building integrationLessons learned: This project shows that integration of solar power in buildings in a good and nice way can be possible and that solar power can not only be useful in an energetic and renewable way, but also be esthetically valuable.
PV ownershipThe Municipality of Houten will eventually be the owner of the PV system.
Tariffs and metering
Remarks and recommended readingThe combination of transparent solar panels and special architecture, etc has increased the publicity possibilities. The location of the fire department building, along a main road, close to youth and sport centers, contributes to the attractiveness as well. Many parties have been involved in the execution of this project.
