Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15927-4 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 89, Thermal performance of buildings and building components, in collaboration with Technical
Committee ISO/TC 163, Thermal performance and energy use in the built environment, Subcommittee SC 2,
Calculation methods in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
ISO 15927 consists of the following parts, under the general title Hygrothermal performance of buildings —
Calculation and presentation of climatic data:
 Part 1: Monthly means of single meteorological elements
 Part 4: Hourly data for assessing the annual energy for heating and cooling
 Part 5: Data for design heat load for space heating
 Part 6: Accumulated temperature differences (degree days)
Future parts are planned on the following subjects:
 Hourly data for design cooling load
 Calculation of a driving rain index for vertical surfaces from hourly wind and rain data
