Sustainability WA

Commercial Energy Efficiency

Let Sustainability WA assist you with your next commercial project by providing an easy to read, cost effective solution.

Deemed To Satisfy

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

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 Services

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:

  • Your development is in a Metropolitan Redevelopment Authority area and you need an accredited Green Star Consultant to comply with their requirements.
  • Your development is for a government body and they have requested a minimum Green Star level.
  • Your development guidelines mandate a minimum Green Star Rating.
  • You or your client wish to ensure the development is sustainable and liveable and take advantage of the benefits listed below.

Some of the benefits of having your project assessed against the Green Star criteria are:

  • Lower operating costs
  • Higher return on investment
  • Attract and retain tenants
  • Enhanced marketability
  • Productivity benefits
  • Reduced liability and risk
  • Healthier places to live and work
  • Demonstration of Corporate Social Responsibility
  • Future-proofed assets
  • Competitive advantage

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.
