(6) Has a before/ after assessment of homes been undertaken using a rating tool or other methodology; if so, what were the results.
Ms Berry: The answer to the member’s question is as follows:
(1) a) In the 2016-17 financial year, 1,245 homes received improvements under the Energy Efficiency Program.
b) The program ceased at the end of 2016-17.
(2) The full range of upgrades available under the energy efficiency program included ceiling and cavity wall insulation, draught sealing, pelmets, gas and electric boosted solar hot water systems, 5 star gas hot water systems and panel heaters. Passive elements such as ceiling insulation, cavity wall insulation and draught sealing are considered the most cost effective measures to improve thermal comfort as they are not subject to a residents use and behaviours.
(3) Yes, the program included draught sealing.
a) In 2016-17, 1,036 properties received draught sealing under the program. It would be administratively inhibitive to ascertain how many properties received this over the 10 years of the program from 2007-08 to 2016-17.
b) The average cost of draught ceiling is $375.00.
(4) Yes the program included the installation of cavity wall and ceiling insulation.
a) Approximately 3,100 properties received ceiling insulation and approximately 1,300 received cavity wall insulation.
b) There is no typical installation of insulation. Housing ACT properties are assessed at the time of installation to determine insulation requirements. Some properties may need a full roof insulation replacement whilst others may only need a top up to the required standard. Not all walls are always completed on the cavity wall insulation program, often western and southern walls are completed to address specific issues such as condensation and sometimes whole properties are completed. Housing ACT properties also vary in size from one bedroom to five bedrooms properties.
c) Taking into account the information in answer 4) b) the average cost of wall insulation is $2,750.00 and the average cost of ceiling insulation is $1,450.00
(5) Yes the program included appliance upgrades such as hot water systems and some heaters.
a) There have been 868 heat pump hot water systems, 1,043 solar hot water systems, 616 gas storage hot water systems and 63 panel heaters installed.
b) The average cost per home is not available. However, the average cost per appliance is:
• Heat pump hot water systems - $3,500.00
• Solar hot water systems - $5,000.00
