Your assessor
Kostas Stefanidis is a registered architect (ARBV #20127), HERA accredited assessor (#10231) and certified Passive House designer. His background spans architecture and building performance in Europe and Australia, so he reads your drawings as a designer and tells you what to change to pass, not just whether you pass.

The Value of One Consultant for Planning & Building Reports
Many projects need both planning-stage ESD reports and building-permit-stage NatHERS and Section J reports. Using one consultant for both keeps your sustainability strategy consistent and reduces conflicting documentation, rework and delays.
Prefabricated Building Advisory
NZEB also advises on prefabricated and modular construction, assessing construction methods and materials for thermal performance, buildability and cost. With Passive House design expertise in-house, we coordinate airtightness, thermal bridging and ventilation early in the design. [Learn more about Passive House].
