Energy Efficiency (Hansard, 22 July 1999)

§ Mr. Meale

By 31 March 1998, energy efficiency in Government Departments had improved by just over 18 per cent. since 1990–91, as measured by the Total Cost Indicator.

Full details are given in the tables which have been placed in the Library; the overall estate improvement is shown in Table 4. The tables give a summary.

The tables include revisions to figures for earlier years revealing better performance than previously reported. In particular, the 1996–97 figure for the Army has been revised to take account of a large estate increase which had been inadvertently omitted, and this restores not only the Army's own steady progress but that of the whole government estate, to 17.5 per cent. instead of to 15.1 per cent. as previously reported in that year.

Energy management in individual Departments is a matter for those Departments and their Green Minister. However, the Government aim to be at the forefront of good practice to improve energy efficiency, and progress is reviewed regularly by Green Ministers under the Chairmanship of my right hon. Friend the Minister for the Environment. We have developed and are now piloting new performance indicators which will, for the first time, enable comparisons with independent standards of good practice across the economy. These are likely to form the basis of the new campaign starting in April 2000.

The results for the former Department of the Environment and the Department of Transport have now been consolidated for all earlier years to allow a 583W continuous series for the Department of the Environment, Transport and the Regions. DETR's overall performance in 1997–98 has slipped relative to 1996–97 as a result of the continuing relocation and rationalisation of its accommodation in London and elsewhere, in particular,

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 20 per cent. by 31 March 2000 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. Conversation 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.
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 and the figure '0' for some Departments does not necessarily mean there has been no investment, just that the investment was not clearly identifiable.
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.
⁴ The energy performance for MAFF's 'Main estate' and its 'Laboratories' continues to improve through ongoing investment in energy schemes, monitoring of energy at local level and taking appropriate action as well as central initiatives including continued staff awareness programmes.

the need to run a number of old and new buildings in parallel while changes took place. However, the Department's two new headquarters buildings at Eland House and Ashdown House were fully occupied by the end of March 1998 so future results should reflect this.

⁵ The DETR's figures have been compiled from the former Environment and Transport Departments. The Department now has a greater proportion of air-conditioned buildings than in the base year, because of estate rationalisation, relocation to new HQ buildings and inclusion of some Government Offices for the Regions. Performance in 1997–98 was adversely affected by parallel operation of both old and new buildings while staff moved from one to the other.

⁶ HSE was removed from the DfEE estate on the formation of that Department. QEII Conference Centre is reported separately because of its business led demands. The initial sharp rise in consumption following the 1990–91 base year was directly attributable to increased revenue earning activity, which has continued throughout the reporting period, and the more recent decline in consumption reflects the effect of energy conservation measures undertaken at the site.

⁷ Rationalisation of the estate since the base year has led to staff moving from several naturally ventilated buildings to more densely occupied air-conditioned buildings, all equipped with information technology equipment.

⁸ Base year is 1991–92.

⁹ Base year in 1991–92. Data for Natural Resources Institute no longer included following its transfer to the University of Greenwich.

¹⁰ Base year is 1994–95 by which time energy efficient lighting and other improvements already installed in buildings which are already fully air-conditioned with intensive IT usage.

¹¹ 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.

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.

¹³ In civil departments, the effect of estate changes is allowed for by dividing consumption by floor area. In MOD, floor area is sometimes not meaningful (e.g. in relation to security or runway lighting) and also not often available, so estate changes are allowed for by being explicitly excluded from the calculations, i.e. the energy consumption of new facilities is removed, and for facilities no longer part of the estate, the consumption for the last full year of operation is added back. In most cases, such changes are small compared to the total and can often approximately cancel each other out.

¹⁴ It is almost impossible to produce any meaningful results to date for MOD's Procurement Executive (PE) since it has suffered major estate gains and losses over the past 10 years and now consists largely of one recently built large office. The standard MOD methodology produces a meaningless 'no change' result (since the present estate is almost entirely different from the original).

¹⁵ This shows the combined results for the whole of the Government estate based on the data in tables 1,2 and 3. It is not a simple average of the data, but reflects the proportion of total consumption represented by each part of the estate (see also note 3). Some Departments have a different base year, and the individually agreed base year has been used for the purposes of this table, where appropriate.

¹⁶ In some instances the base year is not 1990–91, but for the purposes of tables 2 and 5 the agreed base year has been used in the calculation.

¹⁷ The figures quoted here for the Home Office have been weather-corrected in the same way as for all departments. Figures quoted elsewhere were provisional, not yet weather-corrected and therefore showed higher apparent progress.
