With climate change being at the forefront of challenges we must begin to address, we have to reconcile with adapting our lives to the state of the world we live in. From buying tote bags and metal straws to reducing meat consumption, much of the actions we are to personally take are often cumbersome. It hurts my soul to limit my steak burrito intake to once a week!

Eaves and thermal comfort

By Jamie Bonnefin on May 12, 2021 11:44:47 AM

Building for the Australian Climate.

A building’s access to sunlight is one of the leading factors contributing to its thermal comfort, with the amount of direct sunlight that the building receives greatly influencing the passive heating and cooling factors. However, as the sun’s path varies seasonally, accounting for the required direct sunlight a building needs becomes difficult. The eaves of building construction can maintain great benefits if used correctly.

Materials and BASIX: Autoclaved Aerated Concrete (AAC)

By Jamie Bonnefin on Oct 28, 2016 4:20:15 PM

Autoclaved Aerated Concrete (AAC)

Being conscious about the amount of raw materials used in building products is a key concept when trying to design efficiently, aiming to reduce the overall embodied energy of materials. Autoclaved Aerated Concrete or as it is more commonly known AAC, is an example of a building material that aims to reduce the overall raw material requirements whilst maintaining as many of the original product's structural and functional properties. This is achieved by creating air pockets within the concrete (aeration). These pockets of air have many benefits besides just reducing the amount of materials required to manufacture it.
