WINDOWS | ENERGY EFFICIENCY GRAFTON THE CHANGES TO BASIX WILL DELIVER 83 GIGAWATT HOURS OF ENERGY SAVINGS TO NEW SOUTH WALES’ 16,000 GWH 2020 ENERGY SAVINGS TARGET. TAMWORTH BROKEN HILL DUBBO SYDNEY WAGGA WAGGA CANBERRA PUTTING OUR ENERGY INTO D id you know that homes in New South Wales use around 17 per cent of the state’s energy? With an additional 1.8 million new homes across New South Wales expected over the next 40 years, this is likely to rise even further. The Building Sustainability Index (BASIX) sets specific targets for energy and water reduction in new homes, based on how many people will live in the home, where it is located and its size. From 1 July 2017, BASIX energy targets will be increased to ensure they are: • Consistent with national standards. • Fair for all. • Flexible to a changing climate. Energy targets will typically increase by 10 per cent for houses and low-rise units, and by 5 per cent for mid and high-rises units. Thermal comfort heating and cooling caps will also increase to the equivalent of around six stars under the Nationwide House Energy Rating Scheme (NatHERS). Revised BASIX energy targets for new homes will deliver more than $2.6 billion to the New South Wales community (or around $155 per household) every year for the next 30 years. These changes will bring an additional 83 gigawatt hours of energy savings to the state’s 16,000 GWh energy savings target by 2020. The NSW Department of Planning & Environment worked with a wide range of stakeholders to develop the new targets and will continue to engage on ways to improve BASIX, particularly around water targets which are not changing at this time. A test webpage will be activated in mid- May 2017 to provide an opportunity for users to familiarise themselves with the new assessment tool prior to its official launch in July 2017. KEY DATES 1 JULY 2017 MID-MAY 2017 Website trial of the new assessment tool. The new energy target and thermal comfort caps ‘go-live’ for: 1 APRIL – 30 JUNE 2017 • Projects starting from 1 July 2017 onwards. Certificates issued during this time can be lodged with consent authorities (Council or PCA) after 1 July, provided the certificate is no older than three months from date of issue. 24 Winter 2017 • Projects in progress with no existing Certificate. • Certificates issued before 1 April 2017 not already lodged with the consent authority. LEGEND N/A E4 E3 E2 E1B E1A AT A GLANCE Changes to BASIX policy settings: ENERGY • Updated heating and cooling defaults where no active systems are selected. • Updated small-scale technology certificate (STC) methodology for solar hot water and heat pump systems. THERMAL COMFORT • Removal of the ‘Rapid’ assessment method. • New DIY assessment tool aligned to new heating and cooling caps and with improved window selections. • Improved window section with up to 40 windows based on the 88 ‘NatHERS default’ types. • Provide clearer conditions on limitations for use as a ‘deemed-to- satisfy’ method aimed at common forms of class 1 building. • Improved pass/fail feedback. WATER • Water targets are not changing at this time. More information on accessing this trial version is provided on the BASIX website at www. planningportal.nsw.gov.au/planning-tools/basix
