Thermal performance of buildings - Transmission and ventilation heat transfer coefficients - Calculation method

ISO 13789:2017 specifies a method and provides conventions for the calculation of the steady‐state transmission and ventilation heat transfer coefficients of whole buildings and parts of buildings. It is applicable both to heat loss (internal temperature higher than external temperature) and to heat gain (internal temperature lower than external temperature). For the purpose of ISO 13789:2017, the heated or cooled space is assumed to be at uniform temperature.Annex C provides a steady‐state method to calculate the temperature in unconditioned spaces adjacent to conditioned spaces.NOTE Table 1 in the Introduction shows the relative position of ISO 13789:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

It is applicable both to heat loss (internal temperature higher than external temperature) and to heat gain (internal temperature lower than external temperature).

Thermal performance of buildings - Transmission and ventilation heat transfer coefficients - Calculation method

ISO 13789:2007 specifies a method and provides conventions for the calculation of the steady-state transmission and ventilation heat transfer coefficients of whole buildings and parts of buildings. It is applicable both to heat loss (internal temperature higher than external temperature) and to heat gain (internal temperature lower than external temperature). For the purpose of ISO 13789:2007, the heated or cooled space is assumed to be at uniform temperature.

What is the Redline format?
The Redline + service - standards comparator allows you to easily and simply identify major changes between the current standard and its last canceled version.

At a glance, you will be able to identify the additions, deletions or modifications to a text, table, figure and formula.
