On the impact of night ventilation through motorized windows on the energy and thermal performance of office buildings

Global and local climate changes affect the energy performance of buildings, especially during the warm season, with relevant increase of cooling uses in mechanically cooled buildings and discomfort hours in naturally ventilated ones. The ventilative cooling is proved to be a promising strategy to tackle this threat, however installing new ventilation systems in existing buildings is challenging in technical and economic terms. The strategy can be also pursued by motorized windows duly operated.
