- Commercial buildings
Mixed climate, (3 prescribed climate zones)
State of NSW code, BASIX is required for all developments which contain new residential dwellings or alterations and additions to a dwelling. . A dwelling is defined as 'a room or suite of rooms occupied or used or so constructed or adapted as to be capable of being occupied or used as a separate domicile'.
The index includes elements that become prescribed once chosen from the online index. A BASIX certificate must accompany any application for development approval, complying development certificate or construction certificate. The selections made by the applicant in the BASIX online assessment tool, shown as commitments on the BASIX certificate, become prescribed (regulatory) conditions with the granting of consent (building approval).
The performance targets vary according to the location of the building. Primary energy use is calculated using software in KWh for electricity and Mj for gas, and then converted to CO2 emissions using NSW GHG intensity figures for the appropriate fuel source.
"The BASIX Energy performance target vary, depending on the type and location of the building. These variations ensure BASIX remains cost-effective and fair to everyone. Over 80% of all new homes will have to meet the maximum Energy targets. • The average greenhouse gas reduction for all building types across NSW will be 36%. The BASIX Energy section assesses these main energy uses, including the loads from Thermal Comfort, and is a more meaningful indicator of the dwelling’s overall energy performance."
Primary energy use, in KWh for electricity and Mj for gas, are calculated in the software and then converted to CO2e using NSW GHG intensity figures for the appropriate fuel source.
Research is been undertaken at this stage.
- Passive cooling
- 可再生能源 （太阳能、光伏等）:
Rated electrical output of photovoltaic system (peak kW,) solar hot water system requirements. Rebate schemes available for solar and heat pump hot water systems.
Coefficient for Comparison of Climate Zones
|G 值 / 太阳得热系数||0.42||-|
- Thermal bridge demands
The BASIX system encourages the use natural ventilation first and foremost, then most efficient systems are suggesed consecutively thereafter.
- Domestic Hot Water COP - Heat Pump:
The BASIX system encourages selecting efficient systems, most efficient individual hot water system to install is solar.
- Value for airtightness:
Only BCA requirements, air barrier/sealing etc. No ACH requirements or testing.
Between 0- 20 years
No, this is a Federal Government issue.
The NSW State plan aims to protect the environment through cleaner air and progress on greenhouse gas reductions (Priority E3). This s includes a target to achieve a 60 percent cut in greenhouse emissions by 2050 and a return to year 2000 greenhouse gas emission levels by 2025.
Environmental performance and energy efficiency requirements for public buildings, including mandatory NABERS ratings.
- Levels beyond minimum:
Various discussions have been held in the past with industry groups regarding options to voluntarily promote ‘over-compliance.
- Year historic or aspirational codes (planned) :
- Baseline (actual code if nothing else):
No information available
- Primary Energy Performance Frame Residential:
Approx. 40% less CO2 emissions, targets are also been currently reviewed, 2013-14.
No such scheme presently in place, but could be introduced if supported by policy decision. This is a policy area for the 2013-14 review period.
BASIX is developed in close consultation with the building industry, non-government organisations and local government.
Significant industry training was provided through 2004-2006 as BASIX was rolled out. Further information is provided online through the BASIX help notes and for direct enquires through an email/phone help desk. Various professional bodies, including AIBS, AIA, PIA and ABSA conduct training/PDP sessions for their members.
