Hygrothermal performance of buildings - Calculation and presentation of climatic data - Part 1 : monthly and annual means of single meteorological elements

ISO 15927-1:2003 specifies procedures for calculating and presenting the monthly means of those parameters of climatic data needed to assess some aspects of the thermal and moisture performance of buildings. Numerical values for any locations should be obtained from the meteorological service in the relevant country. ISO 15927-1:2003 covers the following single climate variables: air temperature; atmospheric humidity; wind speed; precipitation; solar radiation; longwave radiation. Meteorological instrumentation and methods of observation are not covered; these are specified by the World Meteorological Organisation (WMO).

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
