Human-Plant Symbiosis by Integrated Roof-Top Greenhouses.

The Integrated Roof-Top Greenhouses (IRTG) are able to create a tight human-plant symbiosis, if provided with a two flows ventilation system, which is conveying O2 enriched air from RTG to the building and CO2 enriched air from building to RTG. Besides improving such way the building’s metabolism, if applied at a large scale IRTGs offer us an effective weapon to oppose the global warming, thanks to their carbon offset capability. IRTGs are also able to harvest local renewable energy resources (geo-thermal, solar, wind, etc.), to store them and to manage them in an integrated way with the water resources. A generic model of this system, taking into account the air exchanges between greenhouse, building and environment is discussed, as well as a fuzzy rule base for the air composition.
