For all CIBSE COVID-19 Guidance, see www.cibse.org/emerging-from-lockdown.

This COVID-19 ventilation guidance is for business owners, employers, building owners, managers, operators and those maintaining buildings. 

It is intended to give business owners and managers an outline of ventilation systems commonly encountered in buildings and to advise on how they can be used, now and in the future, to maintain adequate air quality and reduce the risks of airborne infection. 

It is also intended to assist building managers and those who operate and maintain building systems in identifying the areas of a building, and elements of ventilation systems, that may need particular attention in order to reduce risk to building occupants. 

It is relevant to all types of building ventilation system, whether natural, mechanical or full air conditioning.
