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.
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.
For 14 Thermal Comfort, projects complying with Passive House automatically achieve this criteria and gain 2 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.
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.
For 16 Peak Electricity Demand Reduction, projects complying with Passive House automatically achieve this criteria and gain 2 pts.
