Owner approach of sustainability
An adept of contemporary green energy production technologies (photovoltaic electric production installation on the old house), eager to go further in the passive and fanatical concept of computer technologies applied to the building - hence the interest for the"smarthome"-, the master ofThis work became sensitive to the health/quality aspects of indoor air following health problems in her children, these problems were related to the poor indoor air quality of the old house (expert assessments, laboratory analyses), hence the desire to integrate the health aspects in the overall constructive concept and in a sustainable project perspective.
Architectural description
It is a passive single-family dwelling house under massive construction: concrete for load-bearing walls, insulating clay/perlite bricks for the other walls (with humidity regulation function), photovoltaic electrical production system, geothermal energy, underfloor heating, home automation system with braided armoured cables (reduction of electromagnetic fields, WiFi internet access transported by cable in each room and individually manageable by relay), solid wood interior joinery (doors, kitchen), mechanically fixed aluminium windows in order to reduce the risk of damage to the walls, etc;Avoid the use of polyurethane foam), chemically tested oiled parquet and parquet glue, use of biosourced insulation free of harmful substances, lime based interior coating (with moisture regulating function) and non-hazardous mineral paint.
All materials were analysed before use.
If you had to do it again?
Some choices in the trades would be different: mostly time and material quality problems, independent of the"health" aspect of the project.

Reasons for participating in the competition(s)
-Rigorous integration of the concept of healthand well-being in parallel with the concept of passive construction,proving that"passive" and"health" are not in contradiction;-Controls, analyses and measurements upon completion of construction;
-Production of teaching material (documentary film, book, specific documentaries);
-Contact with the owner-occupiersisestablished and maintained in order to allow long-term observation of theconstruction and validate the choices made.
