BUILDING SUSTAINABILITY INDEX
This question is about the Western Australian building sustainability index - BASIX - program. (1) Has the government commissioned an independent analysis of the impact of BASIX on housing affordability? (2) What is the average cost of implementing BASIX per new house? (3) What is the likely pay-off period for BASIX per dwelling? (4) How much water and energy can be saved per dwelling per annum? (5) If there were a full roll-out of the BASIX program over the next 10 years, how much water and energy could be saved? Hon ADELE FARINA

I thank the honourable member for some notice of this question. (1) Yes. Pracsys economists conducted the analysis. (2) For an average four-bedroom, two-bathroom house, the marginal cost of implementing BASIX will range from $460 to $835 per new dwelling. (3) At seven per cent interest, the pay-off period for these costs will range from 2.4 to four years. Further, repayments on a 30-year loan at that interest will incur additional costs of only $40 to $80 a year. (4) For each average four-bedroom, two-bathroom house, complying with BASIX will save from 25 kilolitres to 45 kilolitres of water and from 830 kilograms to 1 170 kilogram of carbon dioxide equivalent gases through energy savings each year. (5) Over the next 10 years, with a full roll-out of BASIX, the state would save around 62 000 megalitres of water, with a value to the state of $72 million at current prices, and 1.58 megatonnes of CO2 equivalent gases, with a value of $240 million.
