Sobrado Solar - Goals and Project
The Sobrado Solar was designed to allow variable family types to live in the house, as there is a favorable cost - benefit ratio to different age groups and lifestyles. There is an extra room with bathroom on the first floor which can be used for guests, or for rental. As both the room and the bathroom are accessible, it may be used by elderly or people with locomotion disability. Further, that room may also be used as a home office. Sustainability was a principle guiding the choice of construction techniques, The project materials, and suppliers, seeking the least natural impact. The degree to which such decisions were taken makes the house innovative within its context:
- by using a prefabricated wood frame construction;
- adopting of a cistern for collecting the rainwater;
- using that cistern as a source or sink of heat for a low-energy climate control;
- elimination of the elevated water reservoir, allowing for a single roof volume;
- making the entire roof a PV surface, thermally isolated, instead of concrete slab and tiles.
- providing a single backyard for all house units, recreating a sense of community;
- implementing their composters and other communal equipment.
The site choice was due to its proximity to the downtown, in good connection with the public transportation network, and a good availability of goods and services, inviting residents to leave the car at home. However, residents are encouraged to possess a small, electric car, which can profit from the availability of solar electricity surpluses.
Students of architecture and engineering, in partnership with specialized suppliers, willing Despite those design constraints, the team cared for, first, comfort in terms of daylighting, temperature, humidity, insolation, air quality and acoustics, and second, for pleasant aesthetics. Everything was planned by a multidisciplinary team of engineers and to bring meaningful innovation to Curitiba and to provide it a good example of life quality in a more sustainable way. The house was elevated from the ground for thermal and humidity cycle reasons, but also as a preventive measure to the probably most common environmental vulnerability: flood, which may be due to the topography, in addition to the fact that urban drained systems are overwhelmed by the water collected in massively sealed surfaces.
