NatHERS stands for the Nationwide House Energy Rating Scheme.
It is Australia’s national system for assessing the thermal performance of new residential buildings, based on their design, in their climate.
A NatHERS assessment predicts how much heating and cooling a home will need to stay comfortable throughout the year. This is expressed as a total heating & cooling load which = the star rating. Ratings range from 0 to 10 stars, 0 being very bad. 10 being amazing performance.
Architectural plans and Software combined with the Assessors skill & knowledge are used to assess heat flows through the building envelope.
Nothing to do with occupant behavior or solar panels.
A NatHERS Assessor considers the following;
- Climate
- Orientation and position on the lot
- Design layout, room location & window size and orientation
- Insulation & thermal mass
- Window frames, glass, size, ventilation openings & shading
- Construction materials and methods
- Ventilation, ceiling fans, breeze paths
Cooler in Summer, Warmer in Winter
