You will require this approval if you intend to install, or substantially modify, an air handling system, water system or cooling tower in a building. These systems use water or other liquids for air conditioning purposes (to heat, cool or modify air), or deliver water to outlet points.
You must also comply with the standards for the installation or alteration of an air handling system, water system or cooling tower. These standards reduce the risk of microbial infection in these systems.
Please consult the Contact Officer for more information.
