— specifies methods for long-term evaluation of the indoor environment obtained as a result of calculations or measurements;

— specifies criteria for measurements which can be used if required to measure compliance by inspection;

— identifies parameters to be used by monitoring and displaying the indoor environment in existing buildings. This document is applicable where the criteria for indoor environment are set by human occupancy and where the production or process does not have a major impact on indoor environment. It explains how different categories of criteria for the indoor environment can be used.
