List of suitable climates for use of this design
This is a social housing typology for rural areas in Chile. The house model is 50 m² and it was designed for a family with 3-5 members. Considering the local climate, the bedrooms and living room are oriented to North. The service areas, kitchen and restroom are oriented to South. All windows and doors are in the North and South facades. The East and West facades of the house do not have windows, to save energy. The material selection criteria sought to employ nonvolatile organic compounds to protect children with cancer living in the house. The exterior high-performance exterior walls and roof work as protection for indoor climate control.
The manufacturer provided technical support during the first six months after the construction of the house. The users maintain the house on their own after that.
Replacement components for different parts of the house can be found in the local market.
The type of design used for the exterior walls and roof allows to maintain the thermal comfort of interior spaces according to local climate, and to reduce the demand for electrical energy for heating.
