The demonstration site is located in Stambruges, 24 km from the city of Mons. It consists of a wood-based envelope house aimed at demonstrating the construction of passive house. The key design strategies are a wood-based structure, large insulation, efficient glazing and a passive house concept. The house might be further developed to be a positive energy house thanks to the installation of photovoltaic panels. The energy performance of the building is determined by a complete measurement system with data acquisition and treatment.
