The bioclimatic greenhouses (also known as bioclimatic solar greenhouses or capturing greenhouses) are structures designed to capture the sun's rays and transform them into energy, in order to contribute to the air conditioning of a home.
To achieve this the bioclimatic greenhouses they must meet very specific technical requirements and can only be made by specialized companies.
One of the main factors to consider when building an effective one bioclimatic solar greenhouse this is the orientation that should preferably be south, in order to be exposed to the sun's rays for as many hours as possible.
The roof and walls of the bioclimatic greenhouse they must be made of glass so as to ensure maximum uptake. At the same time, however, the type of glass must be different because while the glass on the facade and roof must favor radiation, those on the eastern and western sides must prevent heat loss and limit overheating in the summer months.
Another feature of the bioclimatic solar greenhouses concerns the absence of fixed shields to the advantage of mobile shielding systems so as to prevent excessive heating during the summer period.
An important consideration for taxation purposes concerns the volume of the property which is not increased by the construction of a bioclimatic greenhouse as the new volume created is considered a non-taxable technical volume.
It is clear that to be considered such (and not a simple "veranda"), the bioclimatic greenhouse must answer precise technical requirements that allow it to perform the functions of energy saving for which it is designed. A structure built on a low floor, facing north or in the shadow of another structure or building, cannot be classified as a bioclimatic greenhouse and will therefore be considered as an additional volume.
To avoid the obligation of having to stack the new structure, it will therefore be necessary to use a project that complies with the necessary technical constraints in order to comply with municipal and regional regulations, also with regard to the cubic volume limits or any constraints provided for on the property.
Among the most important regulations provided for by law, I would like to point out that relating to the maximum size which can reach up to 15% of the surface of the house, capturing greenhouse it is an accessory structure. It will be possible to reach a size of 30% of the surface of the house only after obtaining a special permit.
A valid summary of the characteristics and advantages of bioclimatic greenhouses is the following infographic created by the company specialized in the construction of bioclimatic greenhouses and other high-level building solutions, Baltera, on whose website you can find more information.
