Other Information

The “maison Rubens” is a typical middle-class row house from late 19th century, in neoclassical style. It reflects the Belgium bourgeoisie life at this period. House is organized in 3 zones: a main part including reception and living space (2/3) and secondary space for stairs, services and corridors (1/3). It has a heritage interest within its decorated front façade (balcony, ceramic tiles and blue stone) and the stucco ornamentation on the ceiling and cornicing at the top of the wall, as well as its marble mantelpiece. Since 1888 (date of construction) no major renovation had been done. The building was almost in its original condition, but in very bad conservation state. The renovation followed two main goals: i) very good insulation (using bio-based materials) and mechanical ventilation of the whole house while conserving the valuable heritage details. ii) energy consumption below 60 kWh/m²y

The overflow system involves a lots of ducts. Most of the time their are set inside the suspended ceiling. Because the stucco ornamentation should be conserved the ducts have been placed into the chimney pipe. the air is blown in the room from the lateral side of the chimney toward the external wall to decrease all condensation risk. the ventilation system has been place in the basement and the duct were insulated
