Ventilative cooling on its own may not be sufficient to avoid overheating problems and maintain a good thermal indoor environment during heat waves. The effectiveness of ventilative cooling is strongly dependent on the building's design, the local climate, and the … Continue reading →
Ventilation provided by thermal, wind, or diffusion effects through doors, windows, or other intentional openings in the building. Natural ventilation systems may be either manually or automatically controlled. The latter is normally needed in non-residential buildings in order to realize … Continue reading →
Cooling of the exposed thermal mass of a building by the use of nighttime outdoor air and thus providing a heat sink during the following day. The airflow is induced by pressure differentials, while the cooling mechanism is based on … Continue reading →
Hybrid ventilation is a two mode system which is controlled to minimise the energy consumption while maintaining acceptable indoor air quality and thermal comfort. The two modes refer to natural and mechanical driving forces.
Continue reading →Ventilative cooling can both remove excess heat gains and increase air velocities – thereby increasing the thermal comfort range.
Continue reading →Yes. Ventilative cooling should be conceived as an integral part of an overall design strategy including adequate solar protections, intelligent use of thermal mass and sometimes support of active cooling which can help improve thermal comfort.
Continue reading →No. Ventilative cooling may be achieved either through natural or mechanical ventilation or a combination of both.
Continue reading →In order to be correctly accounted for, ventilative cooling strategies require rather mature assessment methods for thermal comfort and ventilation effects. These assessment methods should include thermal comfort criteria as well as ideally, indoor air quality, visual comfort, and noise. … Continue reading →
Several studies have demonstrated the energy savings potential of ventilative cooling techniques. Consult the list of articles below with details on the energy saving potential.
