Bioclimatic greenhouse, often called solar greenhouse or capturing greenhouse, a real green and comfortable solution and, if well done, also aesthetically interesting and elegant. It is not new, or rather, today it is for many who are discovering it due to the fact that it brings together characteristics of biocompatibility, comfort and elegance, but already the Romans used the bioclimatic greenhouse. They installed some in the hortus to force the growth of some types of plants that would not have been perfectly comfortable without any protection.
Of course today's solar greenhouses are not like those of our predecessors but the logic with which they are built and used is the same. In Germany they are more common than in Italy, there are the Wintergarten, in many houses in this country as well as in the Nordic ones: real places where you can spend hours and hours, especially in winter, in enjoy the light and the heat coming from natural source. The sun.
Habitable bioclimatic greenhouse
As they do in Germany and other countries with a similar focus on environmentally friendly architectural solutions, the bioclimatic greenhouse can be used as a living area of the house. It is even very trendy and exclusive, there are those who would dream of having it even just to be able to invite friends to dine there or to spend hours reading or sipping tea.
It is a habitable area in winter and summer, it can therefore be interpreted as an additional space to all intents and purposes "to live" but which does not affect the total volume. Not bad as an opportunity! In addition to being habitable, is a naturally thermoregulated volume, cool in summer and warm in winter.
Bioclimatic greenhouse: prices
The prices of this structure vary a lot from case to case, for size and dimensions, but also because of the materials and any more or less agile architectural contexts. At the net price that we see on the quote, we must subtract the value that a bioclimatic greenhouse gives our house if we should ever sell it.
Let's consider, in the long run, too the reduction of carbon dioxide emissions up to 20% with a considerable saving on the energy bill.
Bioclimatic greenhouse: legislation
This opportunity definitely does throat to many, it is therefore essential to regulate it and inform themselves about regulations in force in the area where you want to proceed with the realization before getting excited and investing.
First thing to clarify is that the bioclimatic greenhouse it is not a veranda, they can be confused because they both consist of glass walls adjacent to a building, but the first must have a particular orientation and precise characteristics. If it does not meet these requirements, then it is not recognized as a green building construction and it is not possible to have the advantages that the bioclimatic greenhouse brings with it.
There are some specifications that also concern the materials to be used, which must limit heat dispersion but allow solar radiation. Another important aspect to pay attention to are the walls that cannot be equipped with fixed shielding systems from the sun's rays.
Bioclimatic greenhouse: distance from borders
The characteristics required at bioclimatic greenhouses may vary from region to region and the distance from the borders is one of them. To get an idea, we can take a look at what happens in Lombardy where this distance should be five meters, it is also true that the Regulation of the Municipality where the building is located.
Bioclimatic greenhouse: permits
To create a greenhouse of this type that meets all the required criteria, the best thing is to ask a professional or an expert technician to design it because it is not a trivial structure, both from a point of view architectural and bioclimatic. There are also some practices and documents to prepare that are not trivial.
To be sure that our solar greenhouse is recognized as such, for example, it is necessary that its net surface is less than or equal to 15% of the useful one of each building to which it is connected. The greenhouse must allow for a reduction of at least 10% of the primary energy requirement for winter air conditioning, can be provided with suitable shields and / or mobile and removable devices and suitable openings to avoid overheating in the summer but it absolutely must not have a heating or cooling system.
Regarding the structure and materials, at least half of the dispersing surface must consist of transparent elements.
