Different Types of Ventilation & Their Effectiveness Based on Airtightness |
Natural ventilation
Natural ventilation describes a passive flow of air due to natural forces (such as wind and thermal buoyancy). This type ofventilation drives the outside air in through purpose-built openings, like windows, doors and vents.
This type of ventilation generally works well for older, less airtight buildings that have more gaps for stale air to leak out of.
For new builds that are more airtight, air movement is restricted and homeowners might need to look for additional ventilation methods. Simply opening a window or door isn't always a viable option.
Since natural ventilation doesn't need any mechanical systems, it's a low-cost and energy-efficient way to ventilate a space.
Mechanical ventilation
Mechanical ventilation uses ducts, fans or other type of mechanical systems to circulate air around a property. It takes away that reliance on cracks, holes and open windows to improve indoor air quality.
This type of ventilation is a must for newer, more airtight buildings. That's because, while an airtight building is great for thermal comfort and energy efficiency (with air leaks causing around 15-25% of heat loss in buildings), it's not so good for ventilation. A poorly-ventilated property can lead to a build-up of moisture, mould, bad smells and airborne allergens.
Heat recovery ventilation (MVHR)
A top-of-the-line ventilation option, heat recovery systems circulate air while also recovering heat from outgoing stale air and transferring it to the incoming fresh air. Without an MVHR system, this heat would normally be wasted, so your energy bill will probably look a lot healthier, too.
A heat recovery system is generally suitable for airtight buildings that require constant ventilation and efficient heating, and there are a couple of options available:
Central MVHR systems: Installed in the central heating and cooling system of the building, and circulate air throughout the building using ducts.
Decentralised MVHR systems: Installed in separate rooms; suitable for retrofitting older buildings.
How should you choose the best ventilation for your building?
Consider the airtightness of your property, along with factors like location, climate, and building use and size, when you're choosing a ventilation system. SGMUSEM can help. Book a free visit and our team can advise on the best way to keep your property healthy and your energy efficiency high.
