Deemed To Satisfy 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 BCA dictates 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.
JV3 assessments model the entire building in a 3D modelling program. We then compare this to another model of the same building that has all the individual components required on the BCA. A maximum energy efficiency load (kWh) is established for the building. We can then change the components of the building as long as this maximum is not exceeded.
This means not all areas need to comply with the minimum areas of the BCA as per the Elemental Provisions Assessment method. If, for example, you had an energy efficient building and found you didn’t need wall insulation, you wouldn’t need to put it in.
You can also use items such as energy efficient lighting to offset your insulation requirements. This means you have a lot more freedom to find a solution without expensive upgrades such as under floor insulation or upgraded glass.
Green Star is a national rating system for buildings and communities that goes beyond the requirements of the Building Code with the aim of establishing buildings and communities that use less power and water as well as promote healthier places to work and live.
There may be a number of reasons why you are interested in a Green Star Assessment and wish to engage in our services:
Some of the benefits of having your project assessed against the Green Star criteria are:
Whatever your reason, we are here to help. Our Green Star services can be provided along with our other Sustainable and Energy Efficiency services, such as Section J compliance and 6 Star Energy Efficiency report or separately.
Life cycle analysis (LCA) is a method used to evaluate the environmental impact of a product through its life cycle encompassing extraction and processing of the raw materials, manufacturing, distribution, use, recycling, and final disposal.
In regards to commercial building, Sustainability WA is able to determine how much of an impact your building is having on the surrounding environment.
