Cross ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces.
It could provide fresh air to interiors, ensuring buildings built for domestic and commercial properties are safe, healthy, and comfortable to live and work in. Replacing stale air with fresher air from outside makes it possible to regulate internal temperatures and humidity.
Why Ventilation is a Good Idea
Ventilation is not only the best way of preventing condensation in your home, it will also dramatically improve indoor air quality. Most ventilation systems provide health benefits by reducing naturally occurring Radon gas and carbon monoxide. As well as this, many units are equipped with filters capable of removing up to 95% dust particles and other allergens.
This can include pollen filters that can both help you keep cool indoors and enjoy the benefits of fresh pollen-free air. Hayfever sufferers can benefit massively from a place where they can escape the pollen and focus on bringing the symptoms under control.
There are four types of ventilation system outlined in the Building Regulations:
- System 1 – Intermittent fans and background ventilation
- System 2 – Passive stack
- System 3 – Continuous mechanical extract ventilation (MEV)
- System 4 – Continuous mechanical balanced ventilation with heat recovery
