An airtight building doesn’t sound all that appealing – how are you meant to get fresh air? How does the building ‘breathe’ (whatever that means)? What about the children!? It’s an undercurrent that rages in the Passivhaus vs ‘standard’ construction realm,...read more

The Victorian Government, in their desire to improve the energy efficiency of residential properties, is considering introducing mandatory disclosure of the energy performance of dwellings.

When you decide to utilise the deemed-to-satisfy route for residential developments, you’ll end up producing a NatHERS (Nationwide House Energy Rating Scheme) model.
Given that it is a building envelope assessment, as part of the process you are required to enter information about the dwelling (be it a single-occupancy house or apartment block) including the geometry, envelope materials and thermal performance.read more

The Australian Building Codes Board (ABCB) recently confirmed that they’re undertaking a process for developing Section J 2019.
This is a sure sign that industry is being engaged and workshops are taking place. Although a three-year timeline is of concern if the code is falling short, it finally allows time to really explore and develop the code response and properly engage with stakeholders.read more

Energy modelling software can create its share of frustration, none more so than that used for assessing dwellings against Section J of the National Construction Code – the modelling analysis also known as NatHERS.
There are a lot of fundamental issues here – the black box nature of the analysis (leaving energy modellers in the dark about the calculation), the absence of accounting for thermal bridging and air permeability, and the lack of education around the WERS database and more.read more

As a Certified Passivhaus Designer, I’ve had some interesting discussions with both friends and colleagues about their perceptions of what they think a Passivhaus building actually means.
It’s time to shed some light on a few of the myths and misconceptions surrounding the Passivhaus concept.read more

Working in the construction industry as an environmental engineer can be disheartening at times, as you watch key attributes of a project get value managed away into the ether.
Design elements are removed that would inherently improve the quality of the building, ensuring indoor environments that would maximise the health and well-being of future building occupants.
There are several techniques that can be used when designing a building to ensure that it is naturally cooler in summer and warmer in winter. Clare Parry clarifies the confusion surrounding Passivhaus design and how builders can become experts in this area.
