Thermal bridges in building construction - Heat flows and surface temperatures - Detailed calculations

ISO 10211:2017 sets out the specifications for a three-dimensional and a two-dimensional geometrical model of a thermal bridge for the numerical calculation of - heat flows, in order to assess the overall heat loss from a building or part of it, and - minimum surface temperatures, in order to assess the risk of surface condensation. These specifications include the geometrical boundaries and subdivisions of the model, the thermal boundary conditions, and the thermal values and relationships to be used. ISO 10211:2017 is based upon the following assumptions: - all physical properties are independent of temperature; - there are no heat sources within the building element. ISO 10211:2017 can also be used for the derivation of linear and point thermal transmittances and of surface temperature factors. NOTE Table 1 in the Introduction shows the relative position of ISO 10211:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

Thermal bridges in building construction - Heat flows and surface temperatures - Detailed calculations

ISO 10211:2017 sets out the specifications for a three-dimensional and a two-dimensional geometrical model of a thermal bridge for the numerical calculation of

- heat flows, in order to assess the overall heat loss from a building or part of it, and

- minimum surface temperatures, in order to assess the risk of surface condensation.

These specifications include the geometrical boundaries and subdivisions of the model, the thermal boundary conditions, and the thermal values and relationships to be used.

ISO 10211:2017 is based upon the following assumptions:

- all physical properties are independent of temperature;

- there are no heat sources within the building element.

ISO 10211:2017 can also be used for the derivation of linear and point thermal transmittances and of surface temperature factors.

NOTE Table 1 in the Introduction shows the relative position of ISO 10211:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

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.
