The two laboratory houses
Both houses are the same in terms of structure and climate conditions, and their exposure to the elements is identical (sunshine, temperature, humidity, rain, exposure to wind etc.).
Both houses comply with the 2005 French thermal regulations (RT 2005) and represent an “average” house for a family of four living in France: a kitchen, a lounge-dining room, four bedrooms, a bathroom, a shower room, a w.c. and a garage with adjoining storeroom, i.e. a four-bedroom detached house with approximately 109m² of living space.
