Text description provided by the architects. The most important sustainability data has to do with the design of passive elements.
Optimal orientation, use of materials from the surroundings and zero energy cost in origin: Tosca volcanic stone, riga recycled wood, glass, concrete and basalt stones in gardening, insulation, waterproofing, etc.
It has no heating or air conditioning due to the benign weather conditions. Its bioclimatic emphasis is on controlling air renewal and hydrothermal control over it, as well as the landscape integration to the environment and harnessing wind power from the park for housing consumption.
The house explores the bioclimatic advantages of an agricultural structure sufficiently sanctioned in time and space as the Canary Gerais for the production of wine.
Optimum shapes to defend from consistently high wind pressure - the circle - optimization of orientations and local materials as well as conceptual inspiration systems in spatial, landscape, and compositional relationships of the project.
Stabilized double sheet Tosca stone walls are placed on the ground allowing the inner air chamber to function as a heat distributor of fresh air from the ground to the inside, through a venturi effect that we create with radiation heating.
The concrete slab covered with topsoil and native planting is kept wet by a drip system, promoting evaporation and thus ensuring constant temperature of the concrete mass, avoiding the effect of radiant response to the interior of the masses exposed to excessive sunlight.
Wooden ventilated chamber directly on the excavated soil and also humidified by a drip system.
Isothermal box incorporated in a design kit will be industrialized in a battery pack with 2000 liters of rainwater for gray water use.
ACS panels circuit, computer equipment batteries and alternators for photovoltaic panels incorporated into the folding canopies of the south porch (they have not been installed as the dwelling is using energy from the park wind mills).
Volcanic pozzolan as insulating material and cladding for the hygrometric roofs. Wood treated with Canary Mulberry from controlled logging, native planting in the Geria space (Tabaibas, Cardones, etc.)
In fact the house is the flexible and transformable space between a very strong geometric footprint on the ground and passive systems that try to enhance the air renewal, directing and controlling the cool sea breezes to ensure a cool shade, to prevent heat accumulation in the materials and actually reproduce very naturally the comfort conditions that nature often provides in a place we use sensibly.
