Interim Guidance on Building Regulations Part L
Building Regulations and Historic Buildings
Balancing the needs for energy conservation with those of building conservation : an Interim Guidance Note on the application of Part L
The Government is committed to reducing global warming by cutting the emission of greenhouse gases. Almost half the carbon dioxide produced in the United Kingdom derives from the burning of fossil fuels to provide energy for heating, lighting, ventilating and air-conditioning buildings.
The revised Part L of the Building Regulations, which came into force on April 1st 2002, seeks to improve the energy efficiency of all buildings. For existing buildings, including historic buildings, this means reducing heat losses - particularly through windows - and also means introducing much higher standards of insulation. To try to ensure that implementing the revised Part L does not harm the special interest and appearance of historic buildings, this Interim Guidance Note provides information and advice to local authorities and applicants. A more detailed Guidance Note is planned which will include technical information as well as examples of recommended best practice.
