Common Practice Interpretations
Local common practice is to use bulk insulation at ceiling level. This Common Practice Interpretation clarifies how “ceiling insulation area” is calculated for Energy Efficiency compliance.
Common Practice Solutions
Whilst local common practice in areas affected by Statement of Planning Policy 5.1 – Land Use Planning in the Vicinity of Perth Airport is to use cavity masonry, framed and composite (cavity and framing) wall construction is also being used. This Common Practice Solution has been developed to provide industry with a construction description for steel framed wall construction.
As-Built Learning Exchange recognises the contribution of Ross Squire Homes in developing this solution.
Local common practice is to use the deemed-to-satisfy assessment method to verify (Class 1 Building) Energy Efficiency compliance. This Common Practice Solution is an update of the 2006 version ABCB Glazing Calculator Add-Ons and includes BCA 2009 Energy Efficiency amendments and reporting for the WA Additions (5 Star Plus).
Local common practice is to use “dome skylights” to provide natural light to internal spaces. This Common Practice Solution has been developed to allow industry to take advantage of skylight natural lighting performance that is three times that of vertical glazing, and to provide the generic thermal performance data required to verify energy efficiency compliance.
As-Built Learning Exchange recognises the contribution of BGC Residential, Summit Home Improvements, and Summit Homes in developing this solution.
Local common practice is to use a standardised metal fascia as the junction between of the eaves soffit and roof cover. This Common Practice Solution has been developed to provide industry with a standardised metal fascia for zero lot wall construction that allows for more efficient work practices to achieve Fire Separation compliance.
