Energy changes due

MATERIALS

THE GOVERNMENT is set to unveil its plans for the energy efficiency of buildings this month.

The Office of the Deputy Prime Minister will issue its proposed amendments to part L of the building regulations for public consultation on July 21.

The document is tipped to include new ways to calculate a building's energy efficiency.

It is expected that the old 'elemental method', which calculates the sum performance of a building's individual elements such as windows, doors and blocks, will be dumped in favour of the 'whole building performance'methodology.

This determines the efficiency of a building as a single structure.
