PRELIMINARY EVALUATION OF VENTILATION AND ACOUSTICS INSULATION OF PARTIALLY OPEN WINDOWS FOR THE PRIN - METAWAVE PROJECT

The PRIN-METAWAVE project aims at providing innovative solutions that might simultaneously satisfy different requirements. Windows have multiple roles in assuring a good façade performance: they must provide natural lighting, give good insulation against outdoor noise, provide ventilation when opened and mitigate overheating by use of special glasses, shades etc. These diverse functions are commonly considered disconnected in building design, so that strategies to control these different systems have been developed with entirely separated approaches. This research project aims to overcome the above-mentioned disconnections in order to advance the technology readiness level of windows based on the acoustic metamaterial science to improve their noise control performance while assuring a good natural ventilation. Preliminary measurements of natural ventilation of an on-site windows in the ITC-CNR real scale ZEB (Zero Energy Building) facility, were performed alongside façade sound insulation measurements both with different window opening.
