Air conditioning systems should be designed to cope with the specific requirements of each laboratory. As a base, each person requires a minimum of 7.5 L/s fresh air (Australian Standard AS1668, Part 2).

Special attention should be paid to the design of systems for microbiology.These should be of the non­recirculation type and have separate filtered exhaust ducting with vents remote from air intakes (Australian Standard AS2243, Part 3).
