This European Prestandard specifies 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. For the purposes of this prestandard, the indoor environment comprises the thermal environment, the air quality and the acoustic environment. This prestandard covers indoor environments where the major concern is the human occupation but excludes dwellings.
