88 PROPOSAL TO REVISE ENERGY EFFICIENCY REQUIREMENTS OF THE BUILDING CODE OF AUSTRALIA FOR COMMERCIAL BUILDINGS approximately 46 per cent of their membership). The AWA survey included both fabricators and system suppliers. Of the total number of respondents, 92 per cent (or 152 respondents) were fabricators and 8 per cent (or 14 respondents) were system suppliers. The fabricator demographic was made up of a mix of small, medium and large suppliers. Results from the fabricators survey follow below. • Most fabricators have access to products that perform higher than the current norm for the industry (currently 75 per cent have access to a window with significant performance in U Value and SHGC). • Most window fabricators currently have the capability to produce double glazed windows (86 per cent of them are currently fabricating high performance products). • Manufacture of double glazed windows and doors is not a large proportion of the overall products being manufactured. For 70 per cent of fabricators, the production of double glazed windows and door represents 30 per cent or less of their total production. • Fabricators have the ability to increase the production of double glazed window and door products to move this product range to be the major product line (75 per cent of their production). The majority of the respondents (76 per cent) suggested that they can do this within a 12 month period. Further, there was positive feedback from the respondents that there will be minimal withdrawal from the industry. • However, fabricators identified the following difficulties associated with increasing manufacture of double glazed windows and door products: – lead-times will increase with the change to the manufacturing mix and there will be a reduction in production efficiency due to the added complexity of double glazed window and door systems; – costs will be higher due to increased site glazing, additional cost to product, extra staff and contractors, re-tooling, training, and increased stock and space required in premises (around 28 per cent of the respondents may require new premises); – increased OH&S issues due to weight of product including manual handling, transport and possibly an increase in injuries; – possible increase in imports at standard sizes, reducing work for local businesses; – possible supply issues on extrusion, hardware and glass. Increased complexity in manufacturing process which impacts production time and precision (more room for error). • Most fabricators (58 per cent) will require capital investment to increase production of double glazed windows and doors.

PROPOSAL TO REVISE ENERGY EFFICIENCY REQUIREMENTS OF THE BUILDING CODE OF AUSTRALIA FOR COMMERCIAL BUILDINGS 89 from $20 000 to $1 000 000 dollars to be invested depending on the size of the fabricator. Investment would generally be required for lifting equipment, tooling, and creating site glazing departments, transport equipment, increased stock and some possible IGU lines. Key results from the system suppliers’ survey follow. • System suppliers can make tooling available for fabricators to manufacture double glazed windows and doors within a six-month period but significant investment is required by this section of the industry for the redesign of suites. • Most systems suppliers (86 per cent) have a full range of double glazed windows and doors available for fabricators to supply to the housing and commercial market. • For double glazed window and door systems to become mainstream suites in the market, redesign will be needed by some of the systems suppliers. Most of this redesign work required can be completed within 18 months. In addition to the survey conducted by AWA, information on capacity of the glass industry to supply high performance products was supplied by the <strong>Australian</strong> Glass and Glazing Association (AGGA) and Viridian. The key points about glass availability are summarised below. • Tinted glass products—there is unlimited supply of tinted glass products available from local and international sources. This means that the glass industry can supply the products to meet the required demand even with significant increases. • Low E glass products —new Viridian coating line capable of producing 40 000 tones per annum which is 4 times the current market penetration. Imported product is also available from many suppliers. • IGU products — the current utilisation of national IGU capacity is running at between 50–70 per cent. Capacity can be increased depending on demand. New IGU lines are being installed throughout the country increasing capacity further. The large commercial market generally sees more imported product being utilised rather than locally manufactured product. It follows then, that there is access and availability of high performance products and the industry has the capacity and capability to meet a significant increase in demand for these products. However, doing so will impose extra costs on fabricators and system suppliers which in turn will impact the cost of the products. The AWA report indicates that survey respondents would be investing up to $20 million; this could mean investment for the whole industry of around $50 million (AWA 2009, p. 37). www.TheCIE.com.au
