ENERGY sustainable solutions that can be introduced retrospectively .
Back to those million-plus lightbulbs , for instance : when identifying opportunities to reduce energy wastage , the lighting was one of the first areas focused on , alongside heating , cooling and ventilation ( HVAC ). Wood explains that lighting usually accounts for around 10-15 percent of energy usage and HVAC around 50 percent , with the rest being equipment .
“ We ’ ve replaced around 80 percent of our globes in Melbourne and around 60 percent of them in Perth , moving from incandescent to LED . With advances in technology and the costs coming down , we ’ re also replacing the fluorescents as well ,” Wood adds .
“ Since implementing our energy reduction strategies over the last five years we ’ ve managed to cut our lighting consumption down to around 35 percent of its previous usage , and we ’ ve reduced HVAC by 20-25 percent . Travis Jones ( HVAC Manager ) and Steven Luxford ( Building Optimisation Engineer ) have been critical in producing these results together with our partners BUENO , Honeywell , Nuvo , EPM & C , AECOM and AE Smith .”
While these numbers are impressive , they ’ re only the beginning for Wood , who says his team looks at the supply chain from every angle to ensure it is optimising opportunities to go green .
“ We ’ re not just interested in a better lighting solution : it ’ s the entire process from A to B that we analyse ,” he says .
“ This means disposing of fluorescent lights in an environmentally conscious way , which can be problematic . There ’ s also a lot of junk out there , so we generally spend at least three months trialing each different light solution before we introduce it , to make sure the offering is right .”
