Energy performance of buildings. Indoor environmental quality. Indoor environmental input parameters for the design and assessment of energy performance of buildings | Status: Current, Project Underway

1 Scope This document specifies requirements for indoor environmental parameters for thermal environment, indoor air quality, lighting and acoustics and specifies how to establish these parameters for building system design and energy performance calculations. It includes design criteria for the local thermal discomfort factors, draught, radiant temperature asymmetry, vertical air temperature differences and floor surface temperature. 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 also specifies occupancy schedules to be used in standard energy calculations and how different categories of criteria for the indoor environment can be used. The criteria in this document can also be used in national calculation methods. This document sets criteria for the indoor environment based on existing standards and reports (listed in Clause 2 and the Bibliography). The document does not specify design methods, but gives input parameters to the design of building envelope, heating, cooling, ventilation and lighting.
