Building Code of Australia (BCA) explained in detail
The BCA is a set of national standards that regulate the design and construction of buildings in Australia. It is divided into several volumes, each covering specific aspects of building design and construction, such as fire protection, structural design, and energy efficiency. The BCA is updated regularly to ensure that it remains current with the latest building codes, standards, and technologies. It's also used with other relevant codes and standards, such as the National Construction Code (NCC).
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.
