Defines the requirements for, and methods of expressing the quality of the indoor environment for the design, commissioning operation and control of ventilation and air-conditioning systems.

This Technical Report specifies the requirements for, and methods of expressing the quality of the indoor environment for the design, commissioning, operation and control of ventilation and air­conditioning systems.

This Technical Report covers indoor environments where the major concern is the human occupation but excludes dwellings. This Technical Report does not cover buildings where industrial processes or similar operations requiring special conditions are undertaken.

The practical procedures, including selection of parameters to be measured during commissioning, control and operation, are not covered.
