Relevance of the Building Code of Australia

Section J of the BCA, which now forms part of the National Construction Code (NCC), was introduced in May 2006. Its objective is to reduce greenhouse emissions through efficient use of energy. It requires buildings to which it applies to include features to facilitate the efficient use of energy appropriate to the function and use of the building, the internal environment, its geographic location and other stipulated criteria.

Section J applies to most classes of buildings.

Verification must be established by either compliance with the 'deemed to satisfy' provisions concerning the construction or modelling using approved thermal calculation software.

The requirements of section J are significant mandatory requirements of the BCA and are likely to become increasingly stringent in coming years in accordance with the National Strategy on Energy Efficiency.
