Part L - Section 6
Section 6 stipulates minimum levels of thermal
performance for walls, roofs and floors in buildings. These
performance requirements are detailed in the table below.
There are three methods of demonstrating
compliance with Section 6 in Scotland:
(1) Target U-value method
(2) Carbon index method
(3) Elemental method
The ‘Elemental method’ is by far the simplest
to use and is suitable for extensions, alterations and new-build
work where the heating system achieves approved minimum boiler
efficiency. To comply, each element of the external envelope of the
dwelling (e.g. external walls, pitched roof etc) must achieve the
required U-values.
