scope:

This International Standard deals with the indoor environmental parameters for thermal environment, indoor air quality, lighting and acoustic. -- This standard specifies how to establish indoor environmental input parameters for building system design and energy performance calculations. -- This standard includes design criteria for the local thermal discomfort factors. Draught, radiant temperature asymmetry, vertical air temperature differences, floor surface temperature. -- This standard 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. -- This standard specifies occupancy schedules to be used in standard energy calculations. -- This standard specifies how different categories of criteria for the indoor environment can be used. But does not require certain criteria to be used. -- This standard sets criteria for the indoor environment for design and energy calculations based on existing standards and reports listed under normative references or in the bibliography. -- The standard does not prescribe design methods, but give input parameters to the design of buildings, heating, cooling, ventilation and lighting systems.
