The research aims to verify the contribution to microclimatic comfort offered by the bioclimatic solar greenhouse at the ENEA Casaccia, F92 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 led to evaluate the gained energy from solar radiation through the glazed surfaces due to the bioclimatic greenhouse and the consequent increase in the operating temperature of the internal environment during the winter season. 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 Temperature hourly trends showed an average increase in the operating T°, during the winter season of about 0.59°C.
Keywords: Bioclimatic greenhouse, energy efficiency, EnergyPlus software, passive solar system, indoor operating temperature, glazing properties.
