Residential Energy Efficiency

Multi-Residential Assessment

EcoForm have experience in a large range of residential developments - no matter how big or what materials are being used, we have you covered.

6 Star Certifications (NatHERS)

One pathway for proving that you house or building project has met the minimum energy efficient home design standard is to gain a 6 star rating (The minimum energy efficient star rating) using House Energy Rating Software(HERS).

This sophisticated software analyses your building plans and assesses the heating and cooling loads required to keep your future house at a comfortable temperature.

It takes into account the full building fabric – Roof, Ceiling, Walls, windows and floors – and the heat and cold that can pass through these elements.

The Energy Rating Depends On:

  • The layout of the home.
  • The construction of its roof, walls, windows and floor.
  • The orientation of windows and shading to the sun’s path and local breezes.
  • How well the above factors suit the local climate.
  • Sealing – Vented down lights and gas vents will significantly affect an energy rating.
  • Colours of material – Dark colours are better in cold climates and light colours are better in warmer climates.
  • Floor coverings – Tiles show a performance gain in areas where there are high heating loads or where there are full height windows allowing solar access to the tiles.

Zero stars means the building shell does practically nothing to reduce the discomfort of hot or cold weather, while occupants of a 10 star home are unlikely to need any artificial cooling or heating.

We can also give you advice on how to increase your energy rating in order to achieve a high star rating – whether that be a change in insulation or house orientation.

BASIX Assessment

A BASIX assessment is required as part of the planning process and is needed before plans are lodged to the council. The BASIX assessment measures your proposed development for sustainability against BASIX targets that are based on the NSW home benchmark average. Once your design has complied with BASIX a BASIX certificate can be printed and attached to your development application for submission to the council.

If your proposed design does not comply with BASIX due to conflicts with heritage controls or because it uses a new technology not recognised by BASIX, an alternate assessment can be requested.

EcoForm is an accredited assessor which means we can take advantage of the simulation method which gives you more flexibility in the design of your development and is not as prescriptive as the Deemed to Satisfy method of BASIX, handy if you want to make use of a greater amount of glazing or non standard design features.

You get your designer to alter the plans to meet the minimum requirements, or if you wish we can mark up the plans for you after the changes have been approved by you. We issue the final certification along with light and water calculations required. That’s it. You will have your energy efficiency documentation.
