To ask the Scottish Executive what targets it has set for energy efficiency and microgeneration in (a) new and (b) existing buildings.
Specific Scottish Government targets already set include:
(a). For new buildings, we have set targets to limit both the carbon emissions and energy demand through the building standards system. Scottish standards are currently the most demanding in the UK. A further review of these standards is presently underway, investigating improvements recommended in The Sullivan Report “ A low Carbon Building Standards Strategy for Scotland.
(b). We have set a target in the social housing sector that, by 2015, all properties should have cavity wall insulation, water tank and pipe insulation and at least 100mm of loft insulation (where these measures are technically feasible in the property). All social rented properties should also, by 2015, have a full, efficient central heating system and a National Home Energy Rating score of at least five.
In addition, from 1 April 2009, houses in all tenures will require to have satisfactory thermal insulation in order to fulfil the requirements of the tolerable standard, which is the minimum standard which all houses must meet.
The most recent Scottish House Condition Survey showed that 50 per cent of dwellings were rated good in terms of energy efficiency on the National Home Energy Rating scale, one of the methodologies used for measuring energy efficiency. This demonstrates a continuation of the upwards trend, from 31 per cent in 2002 to 40 per cent in 2003-04, 44 per cent in 2004-05 and 47 per cent in 2005-06. Just 4 per cent of dwellings were rated poor.
However, more needs to be done to continue to improve energy efficiency and increase the uptake of microgeneration across Scotland. We will address this through the introduction of the mandatory energy efficiency action plan, proposed under the Scottish Climate Change Bill. This will report on the progress of improvements, including relevant milestones, targets and anticipated carbon savings.
