NatHERS explained in detail
The Nationwide House Energy Rating Scheme is the official Australian government rating system for residential energy efficiency. Homes are rated from 0 to 10 stars based on their thermal performance. Most new homes in Australia must achieve a minimum 6-star rating, though requirements vary by state.
Join us in this enlightening episode as we delve into the world of energy ratings and sustainable living. We kick off by introducing AI and machine learning into energy ratings, paving the way for a greener future. Discover the ins and outs of NatHERS (Nationwide House Energy Rating Scheme) and what it takes to achieve a coveted 7-Star rating. Explore the key design elements impacted by these changes, and learn how land orientation and neighboring houses can influence your home's price. We also discuss the shift from 6-Star to 7-Star requirements, the associated costs, and the 'whole of home' perspective. Plus, we address whether now is the time to buy to avoid the new requirements and explore alternative materials for achieving higher energy ratings.
