Departmental Energy

Volume 490: debated on Monday 30 March 2009

To ask the Secretary of State for Justice what steps have been taken by (a) his Department and (b) its agencies to improve the thermal efficiency of their buildings in the last 12 months. (266753)

Steps taken by the Ministry of Justice to improve the thermal efficiency of its core headquarters buildings in the last 12 months cover a range of work such as:

the installation of additional roof insulation;

improved draught proofing of windows;

thermal insulation of pipework;

re-balancing of air conditioning to improve operational, energy and thermal efficiency; and,

the refurbishment of 102 Petty France which saw the building fabric and systems improved to meet the high BREEAM1 standards.

In respect of the Agencies for which the Ministry is responsible:

Her Majesty’s Court Service (HMCS): all new buildings are required to be designed using the Court Standard and Design Guide which incorporates building regulations and includes details of U values (the measurement of heat transfer through a given building material, glass etc., the lower the U Value—the better the insulator) and thermal modelling. The use of the Design Guide assists developers in achieving BREEAM “Excellent” for all new building and “Very Good” for refurbishments. This means that they would be in excess of Building Regulations in terms of thermal efficiency. There are a wide range of factors required to achieve BREEAM “Excellent”, so the extent of the thermal efficiency improvement would vary from building to building so as to achieve the best overall thermal performance for that building.

HMCS has carried out research to ascertain which types of building from the existing stock are the most energy efficient. HMCS has used this information to prioritise the retention of the most energy efficient buildings, the disposal of the least energy efficient, and targeted improvement of the thermal efficiency of all retained building stock. This is leading to an ongoing improvement in the thermal efficiency of the overall estate.

Tribunals Service: no specific work has been undertaken in the last 12 months.

National Offender Management Service—Her Majesty’s Prison Service (HMPS): In undertaking a Carbon Management Programme (from June 2008) HMPS are identifying cost-effective opportunities for saving carbon. Included in these are building fabric improvements to improve the thermal efficiency. These opportunities are being costed and prioritised, and will be implemented subject to approval of the implementation plan.

HM Land Registry have not taken specific action to improve the thermal efficiency of their buildings, in the last 12 months, mainly because they carried out this work on most of their buildings over a lengthy period prior to then especially in relation to providing double glazed windows.

The National Archives (TNA): no direct steps have been taken to improve thermal efficiency of TNA’s Kew site in the last 12 months. The Carbon Trust and TEAM Energy Auditing Agency have provided energy saving recommendations.

1 For over a decade, BREEAM has been used to assess the environmental performance of both new and existing buildings. It is regarded by the UK’s construction and property sectors as the measure of best practice in environmental design and management.

To ask the Secretary of State for Justice what recent progress his Department has made towards the target of increasing its energy efficiency per square metre of its Estate by 15 per cent. by 2010, relative to 1999-2000 levels; and if he will make a statement. (266885)

The Ministry of Justice and its Executive agencies have made progress towards the target of increasing energy efficiency per square metre of estate by 15 per cent. by 2010, relative to 1999-2000 levels. In 2007-08, we achieved an 18.8 per cent. reduction in energy use. This information was published in the seventh annual “Sustainable Development in Government” Report (SDiG) at:
