Elemental and Heat Loss Methods

 

The requirements laid down by the Section 6 Elemental and Heat Loss Methods, as applying to non-dwellings, can be set out as follows. The numbering system used here is that used in the <Virtual Environment> implementation. Paragraph numbers refer to the Technical Standards document^[1].
