(5) How many Housing ACT properties have an energy efficiency rating of (a) unrated, (b) zero stars, (c) one star, (d) two stars, (e) three stars, (f) four stars, (g) five stars and (h) six stars.

(6) What mechanisms does the Government use to assess the energy efficiency of properties that do not have an energy efficiency rating.

Ms Burch: The answer to the member’s question is as follows:

(1) 11,572 as at 28 February 2011.

(2) The following table represents, by financial year, the number of properties that have received energy efficiency improvements from 07/08 to end of February 2011:

Financial Year

Number of properties

Cost to Government

2007/2008

255

$0.978 million

2008/2009

1219

$3.253 million

2009/2010

1353

$1.855 million

2010/2011 year-to-date

1011

$1.638 million

* Please note a large number of properties have had improvements carried out in more than one financial year.

It is expected that approximately 80 more properties will receive energy efficient improvements in the remainder of the 2010/11 financial year.

(3) To date some 22% of the current portfolio has had energy efficiency improvements made to the property.

(4) Properties are prioritised for improvement based on criteria which has the most significant impact on improving energy efficiency and the thermal quality of the building shell. The criteria are:

Properties without adequate ceiling insulation;

Properties with electric storage water heating (pre-1999 highest priority);

Large brick veneer properties without wall insulation;

All separate properties; and

Remainder of properties.

(5) Housing ACT only has these details available for acquisitions from the last 10 years. The following table represents the energy star ratings of properties where known and how many properties where the rating is unknown:
