Building name: Stambruges house
Location: Stambruges, Belgium
Status: In operation and monitoring since December 2015
Surface: 219 m2
Building use/type: Prefabricated wooden family house
Climatic zone: Oceanic
The Belgian demo site consists of a wood based envelope house aiming at demonstrating the construction of passive house. It is located in Stambruges, 24 km from the city of Mons, in Belgium. The key design strategies are a wood based structure, large insulation, efficient glazing and passive house concept. The house might be further developed to be a positive energy house thanks to the placement of photovoltaic panels. The energy performance of the building is determined based on a complete measurement system with data acquisition and treatment.
Demo site team: FD2, UMONS
Architect studio Format D2 (FD2) is specialized in building very low energy and passive buildings. The University of Mons (UMONS) contributes to the building monitoring. In addition, 22 companies have participated in the construction in order to have the best quality and cost.
Schedule: The construction started in February 2015 and finished in November 2015. The building monitoring started in December 2015, when occupants arrived.
The energy demand at the Stambruges demonstration site is mostly electrical. The only major difference is that the space heating is provided by a wood chimney installed in the house. The electrical consumption is monitored with M‐BUS electric meters and the thermal energy derived from the DHW system is also monitored. A system for monitoring the future the photovoltaic panels has been installed. The room temperature and relative humidity is measured by DHT 22 sensors installed in each room. All the data is collected automatically in a central station. The outdoor Temperature and Humidity data is also collected.
