I have planned at least 6+ star dwelling, heating cooling/heating typically 80 to 100 watts per square metre required.
Can I assume typical pre star rating home is around 2-3 stars ?
Each star inprovement is aprox 10% less energy required. (3 to 6 star 30% less)
Would I need around 60 watts per square meter for 55 metre dwelling (granny flat shed conversion).
Wolud a 3.6kW aircon/heatpump be enough ??
Please comment with suggestions and Ideas.
