Energy efficient home design

The elemental provisions, or Deemed To Satisfy as it used to be called, provides the least flexible way to achieve compliance of energy efficient home design elements but can still be useful in some circumstances, particularly light weight constructions.

The elemental provisions dictate the insulation or performance levels you need to comply with for each energy efficient home design element.

For example, a floor will have to have a certain R value, as well as the walls and so on. You cannot increase the R value in the walls to compensate for less insulation in the floor. Each individual component must comply.
This often makes it difficult to comply with this method.

As always energy efficient home design will be easier with Sustainability WA and we will find the correct assessment method for your project.
