Energy efficiency in British housing
Domestic housing in the United Kingdom presents a possible opportunity for achieving the 20% overall cut in UK greenhouse gas emissions targeted by the Government for 2010. However, the process of achieving that drop is proving problematic given the very wide range of age and condition of the UK housing stock.
Although carbon emissions from housing have remained fairly stable since 1990 (due to the increase in household energy use having been compensated for by the 'dash for gas'), housing accounted for around 30% of all the UK's carbon dioxide emissions in 2004 (40 million tonnes of carbon) up from 26.42% in 1990 as a proportion of the UK's total emissions. The Select Committee on Environmental Audit noted that emissions from housing could constitute over 55% of the UK's target for carbon emissions in 2050.
A 2006 report commissioned by British Gas estimated the average carbon emissions for housing in each of the local authorities in Great Britain, the first time that this had been done. This indicated that housing in Uttlesford (Essex) produced the highest emissions (8,092 kg of carbon dioxide per dwelling). This was 250% higher than housing in Camden (London) which produced the least (averaging 3,255 kg). Among the 23 towns included, Reading had the highest emissions (6,189 kg), with Hull the lowest (4,395 kg). The variations are due to a number of factors, including the age, size and type of the housing stock, together with the efficiency of heating systems, the mix of fuels used, the ownership of appliances, occupancy levels and the habits of the occupants.
In the December 2006 Pre-Budget Report, the Government announced their 'ambition' that all new homes will be 'zero-carbon' by 2016 (i.e. built to zero-carbon building standards). To encourage this, an exemption from Stamp duty land tax was to be granted, lasting until 2012, for all new zero-carbon homes up to £500,000 in value.
Whilst some organisations applauded the initial announcement of the scheme, in the pre-budget statement from the then UK Chancellor, Gordon Brown, others are concerned about the government's ability to deliver on the promise.
In 2003 the housing stock in the United Kingdom was amongst the least energy efficient in Europe. In 2004, housing (including space heating, hot water, lighting, cooking, and appliances) accounted for 30.23% of all energy use in the UK (up from 27.70% in 1990). The figure for London is higher at approximately 37%.
In view of the progressive tightening of the Building Regulations' requirements for energy efficiency since the 1970s (see the history section below), it might be expected that a significant cut in domestic energy use would have occurred, however this has not yet been the case.
Although insulation standards have been increasing, so has the standard of home heating. In 1970, only 31% of homes had central heating. By 2003 it had been installed in 92% of British homes, leading in turn to a rise in the average temperature within them (from 12.1 °C to 18.20 °C). Even in homes with central heating, average temperatures rose 4.55 °C during this period.
