Passive systems seek thermal comfort and energy efficiency using natural resources, without relying entirely on mechanical systems, involving in an integrated approach the functionality of the sun, materials and application techniques, as well as ventilation and natural light.
Analyzing the solar path allows you to take advantage of radiation to heat the building or increase the amount of natural light, thus defining the ideal positioning of the building.
Depending on the conditions of the area, such as temperature, wind, humidity, vegetation and others, the shape of these buildings can vary, thus seeking to increase efficiency and functionality.
Another popular example that has been applied in urban areas is green roofs, which can reduce the temperature flow between the roof and the building by around 70%, as well as promoting biodiversity in relatively grey areas due to dense urban construction.
These systems take on even simpler and more efficient forms if planned in advance.
An ancient ‘technology’ that has been used naturally since the dawn of humanity, today we have all this knowledge available combined with technological development that allows for safer and more reliable application.
