TQ134 ECCHO for v4 Projects v4 May 2021 EHC
Approved Ruling:
Your request that projects using Homestar v4/4.1 be able to use the Homestar v5 ECCHO modelling tool to demonstrate compliance in EHC-1 in place of another energy modelling tool is APPROVED. The NZGBC allows the use of PHPP models under v4, and as ECCHO is built on PHPP, this tool is also acceptable. Please ensure you are using the latest version of ECCHO available to assessors on the Assessor Resources page of the NZGBC website.
