Thermal performance of buildings - Transmission and ventilation heat transfer coefficients - Calculation method (ISO 13789:2017)

Status: Valid

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.
