UNI EN 15251:2008

This European Standard specifies the indoor environmental parameters which have an impact on the energy performance of buildings. The standard specifies how to establish indoor environmental input parameters for building system design and energy performance calculations. The standard specifies methods for long term evaluation of the indoor environment obtainedas a result of calculations or measurements. The standard specifies criteria for measurements which can be used if required to measurecompliance by inspection. The standard identifies parameters to be used by monitoring and displaying the indoorenvironment in existing buildings. This standard is applicable mainly in non-industrial buildings where the criteria for indoorenvironment are set by human occupancy and where the production or process does nothave a major impact on indoor environment. The standard is thus applicable to the followingbuilding types: single family houses, apartment buildings, offices, educational buildings,hospitals, hotels and restaurants, sports facilities, wholesale and retail trade service buildings. The standard specifies how different categories of criteria for the indoor environment can beused. But does not require certain criteria to be used.
