Got a Section J migraine? Here’s your pain relief. Over the past five years, government requirements on energy efficiency in commercial buildings have become ever more stringent. For a long time, commercial aluminium window systems have been found lacking in this area. ThermalHEART™ changes this, delivering to the Australian market a locally designed thermally broken aluminium window system offering an immediate solution to Section J headaches.
ThermalHEART™ – a solution to Section J
The Building Code of Australia, Section J Part 2, sets out requirements for minimum energy efficiency provisions in multi-residential and commercial buildings. As government focus shifts to energy efficiency, these provisions are becoming more and more demanding. Using the elemental Deemed-to-Satisfy method, the Section J Glazing Calculator sets out the minimum requirements for U-values and Solar Heat Gain Coefficients (SHGC), based on climate zone, building size, glass to façade ratio and orientation.
ThermalHEART™ window and door systems have been designed to deliver exceptionally low U and SHGC values. The inclusion of a thermal break in the aluminium window system ensures ThermalHEART™ systems typically meet or exceed the U-values and SHGCs set out in Section J. In general, this means you can use large expanses of glazing – even in extreme climate zones – and still achieve a pass.
