The Nationwide House Energy Rating Scheme (NatHERS) provides homes with a star rating out of ten based on an estimate of a home’s potential (heating and cooling) energy use. By providing a ‘measuring tape’ for energy efficiency, NatHERS helps to make Australian homes more comfortable for their inhabitants and help residents to save on energy bills through smarter design choices. Often good design can reduce the amount of energy needed to keep a home comfortable with no or little additional construction cost.NatHERS star ratings provide information about the thermal performance (heating and cooling needs) of a home’s construction. Star ratings are based on information about the home’s design, construction materials and the climate where it is being built. NatHERS is administered by the Department of Industry, Innovation and Science. NatHERS Accredited Assessors are professionally recognised energy assessors who are qualified in conducting house energy ratings using NatHERS Accredited Software.
