Building envelope air tightness characteristics of the average Australian shopping centre and supermarket perform poorly compared with similar buildings in Europe and the USA. Shopping centres & supermarkets in Europe and the USA undertake a building envelope air barrier evaluation process at the design stage, as well as during and after construction. Australian buildings forego the building envelope air tightness evaluation that is common in Europe and the US. This process helps European and US shopping centres and supermarkets set such a high standard for air quality, energy conservation, and building comfort. This is now changing as many architects, builders, property managers, environmental engineers, air conditioning and environmental engineering contractors are now engaging Efficiency Matrix for the building envelope air permeability design and evaluation process and the retrofitting of existing building stocks.

Efficiency Matrix delivers to the Australian market world’s best building envelope air barrier and duct leakage assessment technology and retrofitting. Efficiency Matrix’s advanced commercial fan pressurisation testing, thermal imaging, and tracer gas testing, as well as proprietary air leakage assessments software, delivers comprehensive reporting and documentation on building air permeability. Efficiency Matrix’s retrofitting team use this data and advanced retrofitting techniques to optimize energy usage, improving building comfort and air quality.
