The principles of bioclimatic architecture


L'bioclimatic architecturecompletely cuts costs related to HVAC systems (Heating, Ventilation and Air Conditioning) and uses the natural elements of the site to build buildings that are thermally efficient and able to meet the requirements ofthermal comfortwithout the use of air conditioning systems.

L'bioclimatic architectureaims to control themicroclimatedomestic by exploiting the sun, wind, water, soil and vegetation through design strategiespassive that optimize the heat exchanges between the building and the surrounding environment.

Indesign of an ecological housecapable of satisfying the principle of "self-sufficiency"Linked tobioclimatic architecture, the first attention is paid to the location and orientation of the property. The orientation must be such as to adapt to the different climatic conditions that occur over the seasons. In winter it is necessary to favor solar radiation on the walls and windows, in summer, on the contrary, it is necessary to shade and promote natural ventilation inside the building.

In winter, thebioclimatic architecturefavors solar radiation to warm the interiors, the focus is on the thermal insulation of the envelope to preserve the accumulated heat avoiding dispersion. In the summer, on the contrary, it is necessary to shade and promote thermal inertia in addition to the natural internal ventilation of the building.

Bioclimatic architecture and insulation
A goodthermal insulationcan improve the energy efficiency of buildings by minimizing - or even cutting completely! - the electricity costs associated with heating, cooling and ventilation systems. External insulation orisolated coat is a technique ofinsulationthermal and acoustics of the walls of a building. We apply panels made of thermal insulating materials such as wood fiber, glass wool, mineralized wool, extruded polystyrene, polyurethane foam, rock wool ...thermal coatit can be made both on the external face of the wall and on the internal one. Thereinsulationit does not only concern walls and ceilings, particular attention must be paid to fixtures which represent a risk factor for heat dispersion, drafts and thermal bridges.

Bioclimatic architecture examples of strategies
Just as insulating the house is essential, the solar chimney also seems to be an excellent ally ofbioclimatic architecture,it is a system that improves the ventilation of a building by exploiting thenatural principle of rising hot air. The solar chimney is just one example, inbioclimatic architectureand, more generally, in thegreen building, it is possible to provide for the installation of heating systems with radiant floor or wall panels capable of guaranteeing maximum thermal comfort thanks to geothermal energy. Even the green roof o the butterfly roof can represent a good opportunity for efficiency for thebioclimatic architecture.
