Lord Rooker: My Lords, in October 2001 we made significant improvements to the energy provisions in the building regulations, which took effect in April 2002. The changes affect both heating and cooling demand. An announcement about further changes will be made in the forthcoming energy White Paper. As well as targeting the construction of new buildings, we are applying the regulations to more work on the existing stock.
Lord Hunt of Chesterton: My Lords, I thank the Minister for his reply. How are the Government and their agencies helping to reach their targets soon through their own procurement programmes and through sponsoring and applying research into new techniques for energy saving and alternative energy systems for buildings?
Lord Rooker: My Lords, an energy White Paper will be published in a few days' time and it will contain some major announcements. It is axiomatic that the Government want to do what they ask others to do; that is, we want to ensure that our own procurement policies are centred on buying products that do not waste energy. We waste some £5 billion worth of energy a year in this country, and the Government, as a public procurer, must set an example.
Lord Rooker: My Lords, the answer is "yes", but I ask the noble Lord to await the publication of the energy White Paper, which will contain a robust response to the PIU report. The noble Lord, Lord Ezra, is right: in some ways, it is trivial to concentrate on new build. There are 25 million dwellings in the country and we build only some 160,000 or 170,000 new ones each year. It is crucial to concentrate on existing stock.
Much to my surprisethings happen in government which Ministers do not always know aboutin researching for this Question, I discovered some advice for noble Lords who may be thinking of doing some do-it-yourself at Easter, perhaps replacing windows and so on. Apparently, replacement windows were covered by the building regulations that came into force in April last year. Today, it is not possible to buy, either for do-it-yourself purposes or through contractors, wasteful energy windows. Therefore, work is being done in that respect. That may not be the incentive to which the noble Lord referred, but it is an incentive in that regulations are being used to ensure that good, low-energy products are available for people to use in their homes.
Lord Skelmersdale: My Lords, is the Minister aware that there is a problem with the planning authorities so far as concerns listed buildings? Many of us would love to replace our "wasteful" windows, as the noble Lord calls them, but are not allowed to do so. Have the Government given any thought to that?
Lord Rooker: My Lords, there is always a problem with planning authorities, as I am constantly being told. I do not accept that, just because a building is listed, it is possible for someone to say, "You have to keep the old junkthe wasteful energy windows". Good planning authorities issue advice to owners of listed buildingsthey are not always large buildings; sometimes they are small cottagessaying that, if they want to replace windows, they can conform with the structure and history of the building and, at the same time, save energy.
Lord Dubs: My Lords, does my noble friend agree that the average householder might well respond to such initiatives if more information were available? Can the average householder be given more information so that, as individuals, we can try to make our houses more energy efficient?
Together with my noble friend Lord Whitty, the other day I visited the BedZED project in South London. It is a low-energy use development of some 80 flats organised by the Peabody Trust, and it is a beacon development. Nothing that it contains is rocket science. Yet the household heating and energy bills are infinitesimal compared with those of the dwellings that surround the development.
Lord Campbell of Croy: My Lords, does the noble Lord agree with the statement in the Question that heating and cooling buildings consumes about half of the energy generated in the United Kingdom? Does he accept that?
Lord Rooker: Yes, my Lords. It is estimated that about 47 per cent of carbon emissions come from buildings: 27 per cent come from dwellings and 20 per cent from other buildings. Therefore, 27 per cent of carbon emissions come from the 25 million dwellings in this country. Thus, the premise of the Question is absolutely correct and we accept those figures.
Lord Glentoran: My Lords, I declare an interest as a non-executive director of the National House Building Council. I agree with the noble Lord, Lord Ezra, that attention needs to be paid to old buildings. However, does the Minister agree that it is important, in particular, to control the use of energy in public buildings such as this palace and museums? It seems that at a certain time of year the central heating goes on and at another time it goes off, and we sweat at the beginning and end of that period. Then the summer comes and the air conditioning goes on and off arbitrarily. There is no regulating control whereby thousands of pounds worth of energy could be saved.
Lord Rooker: My Lords, I accept what the noble Lord says. In a way, that is because, in the past, the concentration has been on new build. Now, the emphasis is on existing stock. The energy savings possible from new build will always be trivial in comparison with those possible from existing stockwhether public buildings or dwellings. If people took the time and trouble to think the matter through, particularly in relation to public buildings, they could save a fortune, whether in light bulbs or through controlling heating systems.
Lord McIntosh of Haringey: My Lords, the Government provide targeted support for the poorest pensioners on top of the foundation of state support for all. Above that foundation, individuals are responsible for deciding the level of income on which they wish to retire. Most people are saving for their retirement in pensions or other assets. But around 3 million people could be seriously under-saving for their retirement, and perhaps 5 million to 10 million people may wish to save more and/or work longer. The Green Paper set out proposals to help those of working age plan more effectively for a secure retirement.
