| TQ155 fRsi internal non-conditioned areas in apartments | v5 | May 2022 | HC4 - Moisture Control | Link | |
|
Approved Ruling: NZGBC exempts the internal wall between an apartment and communal corridor(s) from the credit HC4 fRSI requirements provided the external envelope of the corridor is ‘fully insulated’. This is typical of Passive House practice in the warmer climates of New Zealand as the corridor is now inside the thermal envelope (but not inside the Conditioned Floor Area). An envelope would be considered ‘fully insulated’ provided it meets the minimum, of the schedule R-values in the 2008 H1. This applies to homes up to 8 Star for climate zones 1-5, but with 9 and 10 Star homes proper fRsi analysis would be required to establish if the junctions need to be thermally broken. In climate zone 6 it applies to only 6 and 7 Star homes. |
