Document L: Conservation of Fuel and Power

Recent changes in the Building Regulations are being driven by the need for the Government to comply with EU Energy Performance of Buildings Directive (EPBD).

Reducing energy consumption and eliminating wastage are among the main goals of the European Union (EU). EU support for improving energy efficiency will prove decisive for competitiveness, security of supply and for meeting the United Nations’ commitments on climate change made under the Kyoto protocol. There is significant potential for reducing consumption. With 40% of our energy consumed in buildings, the EU has introduced legislation to ensure that they consume less energy.

L1 Domestic Buildings

Domestic window U Values have been tightened for new build, refurbishment and replacement windows, with greater restrictions placed on the centre pane U Value compliance route.

Window Energy Ratings apply to all windows on existing dwellings and allow the effect of solar gain to offset heat lost though a window. Window Energy Ratings can be significantly improved using low iron glass and thermally enhanced spacer bars.
