An energy rating is simply a calculation of the heating and cooling loads needed to live comfortably in a home. The rating takes into consideration factors such as insulation, glazing, building size, construction type and orientation to the sun.
All new homes, renovations and extensions are now required by law to have a 6-star energy rating. In order to obtain a building permit, you will be required to submit an Energy Rating Report.
The best time to get an energy rating assessment is when your building plans are close to being completed. If you think there may be problems achieving the 6-star rating, or if you want a rating higher than 6 stars, it’s a good idea to start early with a preliminary assessment.
We deliver a fast turnaround on most energy assessments and ratings. We strive to have your rating back to you within 48 hours, or as agreed on commencement. Generally, you should allow roughly 2 days for a single home, volume builds, multi-site developments and commercial projects.
A 6-star rating means that your home has a good level of thermal protection. The star system ranges from 0 (which indicates that your home won’t retain heat in winter or stay cool in summer), through to a maximum of 10 stars. Most homes with 10 stars require almost no artificial heating or cooling and can maintain a comfortable living environment throughout the year.
Probably. If you are extending or altering your home and require a building permit, you will also require an energy rating. Different states have slightly different requirements, so be sure to call us to find out what’s right for your property. Generally, you will need an energy rating if your extension / renovation work represents 25% of the overall dwelling size of your home.
Generally, you will need to provide a set of building plans, including a site plan, floor plans, window schedule, electrical and elevations. For commercial builds, you’ll also need to include an electrical services plan, a mechanical services plan as well as details for any heating, ventilation and air-conditioning systems you plan to include.
If your property doesn’t get a 6-star rating, Six Rate will work with you to find some practical and cost-effective changes. In most cases we are able to offer a number of building alternatives to help you stay on track.
If you take time to ensure that your home is well situated on its block, and has a good initial design, it is usually quite affordable to achieve a 6-star rating. Before you start building, seek advice from an accredited energy assessor such as Six Rate to make sure that you are on the right track.
Only accredited assessors are allowed to conduct an energy rating assessment. Accredited assessors like Six Rate are trained in the assessment process and have the appropriate assessment tools to complete the task.
