The construction of bioclimatic greenhouses is one of the main activities of Landmark Architecture Studio Milano, from the verification of the requirements, to the design, including the requests to the various competent bodies, up to the final realization.
The Bioclimatic Greenhouse, or Bioclimatic Solar Greenhouse, is an architectural element that exploits the greenhouse effect; a technological device that takes advantage of the containment of energy consumption.
In practice, the Greenhouse is an envelope designed to allow incident solar energy to pass through the glass and provide a thermal energy supply to the internal environment. They are therefore glazed spaces placed in the immediate vicinity of the house and often leaned against or integrated that become living spaces. They exploit the solar contributions by taking advantage of the favorable microclimatic conditions, both thermal and luminous. The greenhouse as an artifact is therefore the architectural expression of a natural phenomenon.
The construction of a bioclimatic greenhouse must comply with the reference regulations, in particular the regional law 39/2004 which dictates “Regulations for energy saving in buildings and for the reduction of polluting and climatic emissions”. These rules for climatic devices prevail over the regulations and other municipal standards and are implemented in the municipal regulations themselves.
Article 131 of the Building Regulations also deals with bioclimatic greenhouses and passive systems for capturing energy.
Greenhouses and passive systems for capturing solar energy are not counted for volumetric purposes, in compliance with the following requirements:
- be integrated into the building organization
- have a depth of no more than 1.5 meters
- have a net floor area of less than or equal to 15% of the useful area of each subordinate to which they are connected
- be openable for a surface equal to at least one third of the development of the envelope
- be equipped with screens and / or mobile or removable devices designed to reduce the maximum solar irradiation by at least 70% during the summer period
- guarantee a reduction of at least 10% of the performance index for winter air conditioning
- not be equipped with a heating or cooling system.
An example of an implementation that exploits the principles of the bioclimatic greenhouse is the Serra project visible on the page:
