Bioclimatic greenhouses for energy efficiency and sustainability

The research moves from the most recent regulatory developments in terms of energy saving and more modern technology developments related to the design and construction of high energy performance solar control glass elements to demonstrate the effectiveness of bioclimatic greenhouse systems in improving internal comfort levels reducing non-renewable energy consumption for indoor air conditioning. The research aims to verify the contribution to microclimatic comfort offered by the bioclimatic solar greenhouse built on the first floor of the ENEA CASACCIA building. The analysis was carried out using the opensource software, EnergyPlus, for thermal simulation and dynamic energy diagnosis of buildings, based on the 3D geometric model built using the Google SketchUp software. The simulation made it possible to evaluate the increase of gained energy from solar radiation through the glazed surfaces due to the construction of the bioclimatic greenhouse and the consequent increase in the operating temperature of the internal environment during the winter season.
