Save money… Use energy efficient lighting.

With the cost of essential services always on the rise, especially electricity supply which is used 24/7, it is worthwhile considering LED lighting for your next project.

 We have some cost-saving suggestions for you:

For existing homes:

- Replace existing globes where possible with new LED globe or alternatively have a qualified electrician replace the existing fittings with new LED type. The savings will outweigh the initial cost to replace fittings or globes. -There are also some government schemes going around at present that will cover the replacement of your current downlight globes with new LED globes. Check it out and take advantage of the free upgrade. 1. When renovating or extending (general house extensions): - Ensure that your home designers or your building design call for LED lighting. 2.New homes design: When your architectural drafting is being prepared for your new home design, insist on having LED lights. Have the building designer incorporate the LED lights into your new house plans.

All new home designs and house extensions now need to comply with the new requirements of 5w/m² and the best way to achieve this is by using LED lighting. LED lights are a proven method of energy-saving sources.

Energy Rating Homes in Melbourne

We have been receiving many questions regarding the Energy Rating requirements in Melbourne district. This is a factor that is at the forefront of any new home design or extension and in brief and simple terms, these are the requirements:

  • For any new home design, new townhouse, or new unit design a rating of 6 stars must be achieved.
  • For an addition/extension with a size that is less than 50% of the existing residence, there is a formula that considers the volume and star rating of the existing residence plus the volume and required star rating of the addition (6.0 stars) and takes the average. This gives the required star rating that the entire house (existing plus addition) must meet (SRr = (Ve + SRe) + (Vn x SRn) / (Ve + Vn))
  • For an addition/extension with a size that is more than 50% of the existing residence, the entire house (existing plus addition) must meet 6 star standards.

Energy ratings are conducted by modeling the design into an Energy Rating software program (our company uses the common FirstRate5 software) and some factors that affect an energy rating are the orientation of the home (north-facing, south-facing, etc), building materials, insulation, window locations and sizes, glazing specifications (single, double and their efficiency), open spaces and ceiling heights, air leakage and more.
