Night Cooling

Night cooling refers to the operation of natural ventilation at night in order to purge excess heat and cool the building fabric. A building with sufficient thermal mass, which can be exposed to night-time ventilation, can reduce peak daytime temperatures by 2° to 3° using this strategy.

Night cooling offers the potential to minimise or even avoid the use of mechanical cooling and improve the internal conditions in naturally ventilated buildings.

Good control of night cooling is required in order to achieve maximum free cooling whilst avoiding overcooling and subsequent re-heating or thermal discomfort the following day.

Passivent can offer a range of automated ventilation devices and control systems that can utilise free night cooling and provide daytime ventilation.
