On 29 November, MBIE released the 2021 update to the building code. The main changes include increasing insulation requirements and changes to Acceptable Solutions and Verification Methods.

However, quietly tucked way in H1/VM1 Energy Efficiency Verification Method is a section that now recognises the Passive House Planning Package (PHPP) as a modelling tool that can be used as a means of compliance.

This is really exciting because although the methods required for compliance with the Building Code still leave plenty to be desired (read out position paper here), PHPP is a reliable and accurate modelling tool when used correctly. Passive House designers and consultants receive training in the use of PHPP as part of their CEPH2 course and some of them offer it as an independent service – see certified Passive House designers and consultants here.

If you want to buy a copy of PHPP, we are a licensed reseller and you can purchase it from our online shop.
