Browse Forums Building A New House Re: How to qualify for 6-star energy rating (pre NCC 2022) 9Apr 23, 2024 11:06 am ponzutwo So I have a bone to pick with the star ratings. I built a 7.2 star home about 10 years ago. It is no where near as comfortable to live in as the 6 star i built a year and a half ago. Straight of the bat, the cost to cool and heat the home was more expensive back then than my current larger house with higher electricity prices. Go figure. Do the smart stuff like insulation etc, but temper your expectations between the differences 10 years ago was a different software than we use now. it has had a lot of changes over the past years. Improvments to the software and changes to how Nathers models need to be conducted have made it more stringant. If you modeled your old 7.2 star house now it would probably go down to around 6.5 stars ish. also the energy rating assumes the build reaches a minimum air-changes, but if the builder does not reach this level of sealing then the actual energy usage will be significantly higher.
