HC Deb 17 December 1996 vol 287 cc546-51W
Mr. Yeo

To ask the Secretary of State for the Environment what progress has been made by Government Departments towards the target of improving energy efficiency by 15 per cent. in the five years ended March 1996. [9856]

Mr. Robert B. Jones

The Government's energy efficiency record has improved by just over 14.5 per cent.; very close to the 15 per cent. target we set five years ago. This is an important achievement and reflects much effort and commitment by the staff concerned. I am particularly pleased to draw attention to the very good results achieved on the Ministry of Defence estate. Full details are shown in the following tables.

Energy management in individual Government Departments is a matter for those Departments. Comparisons between Departments need to be treated with care since their estates and activities vary considerably. There have been greater pressures on electricity use, resulting in particular from the growth in use of IT equipment: some very large increases in electricity usage are due to moving a dominant HQ building from naturally ventilated premises to air-conditioned ones. This is in line with trends in the economy as a whole as part of the process of improving productivity.

I am delighted my own Department has been able to exceed the 15 per cent. target, with even more impressive progress having been made towards reducing emissions of carbon dioxide, down by 26 per cent. since 1990–91.

Energy efficiency has been an important consideration in the design of the Department's new headquarters buildings, both of which are expected to be classified as "very good" under the Building Research Establishment environment assessment method—BREEAM.

While these figures are encouraging, we must build on this success. Green Ministers have now agreed a further energy saving target of 20 per cent. by 2000, on the 1990–91 base year, and my right hon. Friend the Prime Minister has given this his personal support. Further savings will be challenging, but I remain determined that the Government should set an example and contribute to the reductions we need in meeting our climate change commitments.

* Base year is not 1990–91. Agreed base year therefore used for the purposes of these calculations.
1 Progress is expressed as a percentage relative to the 1990–91 base year value of the performance indicator in question. Positive figures represent improvement. The standard indicator, against which the target to improve energy efficiency by 15 per cent. by 31 March 1996 is measured, is obtained by weather-correcting energy consumption and converting to costs using "standard prices" for fuel (6p/kWh for electricity and 1.25p/kWh for all fossil fuels) then dividing by floor area. Conversion to money both reflects the relative costs of electricity and fossil fuel and their environmental impact, and the use of fixed prices eliminates the effects of tariff changes which distort the comparison of fuel bills. In August 1995 a report was provided for the Environment Select Committee which gave more detailed background on the energy efficiency initiative and on the indicators used.

2 Although figures have been prepared on a consistent basis, caution should be exercised in comparing the energy use of different Departments and Agencies because of differences in their estate and the nature of their work. For example, the operational needs of prisons and the QEII Conference Centre mean that they have a pattern of energy use which is different from that of a Department which has predominantly office accommodation. Expenditure on energy and investment figures are included for information only. Investment figures relate to clearly identifiable energy efficiency measures undertaken by Departments. Energy efficiency is an integral part of all major construction projects, including building refurbishment and plant replacement; for example, the investment figure for the Lord Chancellor's Department is an estimate, a large proportion of which is accounted for by works justified on operational grounds and does not reflect specifically the proportion of works attributed to energy efficiency.

3 The average performance figure for the civil estate cannot be derived by simply adding together the individual Departmental progress and dividing by the number of Departments because this does not allow for the large variations in consumption. The correct figure is obtained by calculating the value of the performance indicator for the year in question and the base year, for the civil estate as a whole, and calculating the reduction relative to the base year.

4Energy performance is improving despite the addition of new buildings, major refurbishment of specialised buildings, continued growth in the use of information technology, the business led demands of Agencies and longer working hours. Depots have been removed from the reporting mechanism.

5 For consistency with earlier years of the energy efficiency initiative, the Departments of Education and Employment have been reported separately, in the format prior to the formation of the DFEE. Figures for ACAS (now part of DTI) and HSE (now part of DOE) have been included with those for Employment Department and Employment Service.

6 QEII Conference Centre is reported separately because of its business led demands.

7 Since the beginning of the initiative the Department of Health estate has reduced from a large number of naturally ventilated buildings to five densely occupied, mainly air-conditioned, buildings with consequent substantial savings of rent and CILOR. Only 17 per cent. of the Department's 1990–91 estate remains on the current portfolio and comparisons between the 1990 data and current performance are therefore unreliable and do not reflect the real improvements achieved.

8 Base year is 1991–92.

9 Base year is 1994–95 by which time energy efficient lighting and other improvements already installed. Increased Information Technology, and also constant air conditioning during 1995's hot summer months.

10 Workload is increasing, affecting occupancy and requiring offices to be occupied for longer, increasing the use of energy. Greater use of information technology, expansion of the use of air conditioning and the upgrading of lighting levels has increased electricity consumption.

11 Figures exclude the Vehicle Inspectorate Agency. Own investment in energy efficiency advised as 8 per cent.

12 The Ministry of Defence (MOD) estate is different from the rest of the Government estate, and has been undergoing more radical changes. It is therefore treated in a slightly different way. In common with the civil estate, it has greatly increased its use of information technology. Full data for the years between 1990–91 and 1993–94 are not available, so the table shows the results for 1994–95 and 1995–96.

13 Floor area cannot be calculated for the majority of the MOD estate. However, to enable comparisons with data for the civil estate which is adjusted for changes in floor area, a proxy has been used. Changes in consumption arising from estate changes have been estimated as a result of estate adjustments, with appropriate adjustments made to the gross data for the years following the change. In common with other Departments, the MOD has a target to achieve a 15 per cent. improvement by 31 March 1996. Positive figures represent improvement.
