7 Embodied Carbon Reporting Errors That Can Affect Green Star

Image
  Embodied carbon reporting is now a central part of Green Star certification. It measures the emissions locked into a building's materials, from manufacture to installation. This data often feeds into a broader ESD Report , so accuracy matters well beyond the carbon figures alone. The problem is that these reports are detailed and easy to trip up on. Small mistakes in data or scope can quietly undermine the whole assessment. Get the reporting wrong, and you risk losing points or delaying your Green Star certification entirely. Here are seven of the most common errors and how to avoid them. If You’re Preparing for a Green Star Audit, Avoid These 7 Reporting Mistakes 1. Using Incomplete Material Data The most frequent error is missing material information. An Embodied Emission Report relies on accurate quantities for every major building element. When steel, concrete, or glazing figures are estimated rather than measured, results skew badly. Assessors need real data drawn from the b...

7-Star NatHERS Rating Explained: New Energy Standards for Australian Homes from 2023

  What Is NatHERS - and Why Is Everyone Talking About It? Picture this - you are about to build your dream home in Australia. Then someone mentions you need a NatHERS rating. You nod along, not entirely sure what that means. That is more common than you think. NatHERS , short for the Nationwide House Energy Rating Scheme, is the official Australian government framework used to measure home energy rating . It assigns a star rating - from 0 to 10 - based on how well a home's design controls temperature naturally. The higher the stars, the less your home leans on heating and cooling systems. From 1 May 2023, a major shift happened. The National Construction Code raised the bar - all new residential builds now require a minimum NatHERS rating of 7 stars. That is a full two-star jump from the old 6-star requirement. Not only that, but the update also introduced a home performance rating for whole-of-home energy use - covering things like hot water systems, lighting, and appliances. B...
