GBCA Partnership

The Green Building Council of Australia (GBCA), the Australian Passive House Association (APHA), and the Passive House Institute (PHI) have agreed to work collaboratively to promote the design, construction and operations of energy efficient and comfortable buildings in Australia.

The three organisations announced the partnership in 2017 after signing a memorandum of understanding which outlines their commitment to work towards common goals.

The organisations are committed to identifying opportunities to align the Green Star and Passive House, develop events and education offerings, and promote building practices that significantly raise the standard of what green buildings should be.

The Passive House Crosswalk

GBCA and APHA recognise the value of projects pursuing both Green Star and the Passive House Standard in order to promote high energy performing and thermally comfortable buildings.

This document page provides assistance for new buildings seeking to obtain a certified Green Star – Design & As Built rating through compliance with the Passive House Standard. To simplify the process for projects pursuing both programs, GBCA and APHA have developed the following guidance to show how Passive House can assist projects seeking a Green Star rating.

Typically, complying with Passive House Standard will act as a stepping stone to achieving a Green Star rating. This means there will be outstanding Green Star credits that will still need to be met to achieve a Green Star rating. However, critical decisions related to building fabric and systems will assist projects in scoring high in Green Star’s ‘Indoor Environment Quality’ and ‘Greenhouse Gas Emissions’ categories.

Unless noted, this document addresses Green Star – Design & As Built v1.2 and the Passive House Classic Standard version 9f.

Up to 30 Green Star Points?

Overview

The following provides a more detailed guidance on what aspects of Passive House contribute to Green Star credits, and the number of points that will be awarded. A maximum of 30 pts can be awarded under Green Star – Design & As Built v1.2 and the Passive House Classic Standard version 9f.

Indoor Air Quality - 4 pts

For 9.1 Ventilation System Attributes, 9.2 Provision of Outside Air and 9.3 Exhaust or Elimination of Pollutants, projects complying with  Passive House automatically achieve this criteria and gain 4 pts

Thermal Comfort - 2 pts

For 14 Thermal Comfort, projects complying with  Passive House automatically achieve this criteria and gain 2 pts

Green House Gas Emissions - 12 - 20 pts

For 15 Green House Gas Emissions, projects can automatically claim up to 20 points depending on the BCA Class of the building as follows:

  • 4 points can be claimed for the Energy Consumption Reduction requirement in Pathway 15E. In addition, the following can be claimed for greenhouse gas emissions reduction for Pathway 15E.
  • For Class 1a, 1b, and 2 buildings – 10 points
  • For all other classes – 8 points.

Projects can claim further points based on the amount of renewable energy on site. Projects teams are required to provide the total amount of energy consumption without on-site renewable installation (a), the amount of on-site renewable installation (b), and the total of remained energy consumption from the grid. For every 15% reduction over (a) a point can be claimed. In addition, points may be claimed in accordance with the GreenPower requirements in the submission guidelines.

Peak Electricity Demand Reduction - 2 pts

For 16 Peak Electricity Demand Reduction, projects complying with Passive House automatically achieve this criteria and gain 2 pts

Innovation - 2 pts

For 30 Innovation, projects complying with Passive House automatically comply Best Practice requirements in ‘Exceeding Green Star Benchmarks: Building Air Tightness’ innovation under ‘Commissioning and Tuning’ and gain 2 pts
