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.
