Buildings can be ventilated in a multitude of different ways depending on the age, design, location and purpose of the building. Natural ventilation uses windows, doors and other openings to allow airflow through a building that is driven by the weather – the wind or by temperature differences. Mechanical ventilation uses technology to enable airflows and ranges from a simple extract fan such as in a bathroom, through to complex ducted systems that provide air to a whole building. Alongside ventilation, there are a range of technologies to heat, cool or clean the air that can also be used to provide good indoor environments.


Sounds complex? Sometimes it can be, but there are many resources out there to help aimed at professionals and the public:

CIBSE Top Tips on Ventilation – summary of information on ventilation including how buildings are ventilated and some considerations for design and operation.

Ventilation in the workplace – HSE summary of how to manage ventilation in workplaces including a simple video and information on how to assess ventilation.

Breathe Freely– BOHS simple tool to help evaluate ventilation. This was designed for the pandemic but is very helpful for general assessment of ventilation too.

BESA guides to indoor air quality – links to several reports including a beginners guide to indoor air quality and more detailed guidance and assessment approaches
