There are four key methods of ventilation, which can be used individually or in combination. They are:

• Natural ventilation: This type of ventilation relies on natural air movement driven by pressure differences, wind, and temperature variations. It involves using openings such as windows, doors, and vents to allow fresh air to enter a space and stale air to exit.
• Mechanical ventilation: Mechanical ventilation involves the use of mechanical systems, such as fans, to actively circulate and exchange air in a space. This can be achieved through various mechanical ventilation systems that remove stale air or supply fans that bring in fresh air – this can be via extractor fans or positive ventilation input (PIV) units.
• Whole-house ventilation: Whole-house ventilation systems are designed to provide continuous or periodic ventilation to an entire dwelling. These systems distribute fresh air throughout the house, typically through ductwork, and may incorporate filters or heat recovery systems to improve air quality and energy efficiency.
• Spot ventilation: Spot ventilation targets specific areas or rooms that are prone to moisture, odours, or pollutants. It involves the use of localised extractor fans, such as those installed in bathrooms, kitchens, and utility rooms. This type of ventilation helps to prevent localised problems and can complement overall ventilation strategies.

The right type of ventilation system for your home depends on its climate and design. If you’d like a more personalised recommendation, please get in touch with our damp and ventilation specialists!
