Types of Ventilation System
An effective ventilation system is an essential part of any home or business premises. Ventilation refers to any system that allows air to flow and move between the inside and outside of a property, providing fresh air for the occupants.
In the past, buildings relied on natural or uncontrolled ventilation. It could involve opening windows and doors, fixed air vents, and natural gaps in the structure. It is not always effective in a modern property, though, especially as energy-efficient homes and offices are built to increasingly airtight designs. Natural ventilation can either over ventilate or under ventilate a building and is uncontrollable.
Mechanical systems are often required to achieve the right rates of air exchange in a building. It can help safeguard the health of the occupants and prevent issues such as damp.
Adequate ventilation is essential in maintaining a healthy environment, as it:
- Prevents the build-up of excess levels of humidity (which can lead to condensation, mould and can consequently result to health issues)
- Provides air for fuel-burning appliances, such as wood burners
- Removes cooking smells
- Can help remove allergens and other irritants, such as tobacco smoke.
The core ventilation methods are:
- Extractor Fans
- Positive Input Ventilation (PIV)
- Mechanical Ventilation with Heat Recovery (MVHR)
- Mechanical Extract Ventilation (MEV)
