Welcome to the second edition of the Nationwide House Energy Ratings Scheme (NatHERS) Star!

NatHERS Administrator Update

Since the last update, the NatHERS Administrator has continued to deliver reforms to the program in line with activities in its 2015-18 NatHERS Strategic Plan, and in response to decisions made by state and territory and Commonwealth government representatives with oversight for NatHERS operation. 

Updated AAO protocol

The NatHERS Administrator published an updated Protocol for Assessor Accrediting Organisations (AAOs) in March of this year, which comes into effect on 1 July 2016. The current Protocol is operating during the interim period.

We have recently produced a short video for a general audience to build awareness of NatHERS and to promote energy efficient design.

NEW NatHERS Factsheets

In response to common queries, the NatHERS Administrator has produced three new factsheets.

NatHERS in the News!

In March, an article was published in the Energy and Buildings Journal considering the effectiveness of NatHERS as a modelling tool to achieve higher energy efficiency and lower running costs for households.

2016 NatHERS Stakeholder Update

BERS Pro Accreditation

Energy Inspection was granted short-term accreditation for the newest version of BERS Pro, v4.3.0.1 (3.13) in April this year. The software was accredited for use for energy ratings from 1st May 2016.

NatHERS in the News!

In March, an article was published in the Energy and Buildings Journal considering the effectiveness of NatHERS as a modelling tool to achieve higher energy efficiency and lower running costs for households. The paper, written by Timothy O’Leary, Martin Belusko, David Whaley and Frank Bruno, compared two groups of houses in Adelaide – the first in Mawson Lakes, where the houses were older and had lower star ratings, and the second in Lochiel Park, built between 2010 and 2015, and with a minimum rating of 7.5 stars.

Results showed that on average, the Lochiel Park houses used 60% less heating and cooling energy compared to the Mawson Lakes homes. The paper concluded that, even after taking into consideration variations such as occupant behaviour, NatHERS achieves its objectives and provides environmental and economic benefits to homeowners and builders in terms of energy requirements and performance. The authors also noted the need for further extensive research into national energy consumption.
