What is the standard R rating for new home builds

Mark Bryson - Friday, August 01, 2014
The standard R rating on new home builds is a 6 star rating making the home more energy efficient than earlier built homes pre energy rating changes. 

The R rating is achieved by using a combination of building materials and items such as insulation, solar hot water units, double glazing, home orientation, rain water tanks with plumbing to toilets and laundry just to name a few that could be used in your new home build.
