BEAM provides incentives to achieve energy performance better than
the minimum compliance with the local energy codes. Consequently,
compliance with the Building Energy Code (BEC), a government initiative
currently under review for mandatory implementation, is taken as the
energy performance Prerequisite for BEAM certification, unless
otherwise agreed by BEAM Society Limited.
BEC refers also to other 4 other Codes of Practice for energy efficiency,
namely Air-conditioning Code [1], Lighting Code [2], Electrical Code [3],
Lift & Escalator Code [4],in the 2012 version these are all combined into
one code of practice – Energy Efficiency for Building Services
Installations [5].
Performance-based Building Energy Code (PBEC) [6] uses a computer
simulation model to assess energy performance. In the 2012 version,
this is also combined in the same code of practice – Energy Efficiency for
Building Services Installations. Compliance with the BEC automatically
satisfies the energy performance prerequisite, irrespective of the
simulation software and default values.

Whilst the estimation of annual energy use and maximum electricity
demand takes into account improvements to the efficiency of air-
conditioning and lighting systems and equipment it does not embrace all
aspects of energy use in buildings. Therefore, BEAM credits additional
measures that can improve the energy performance of buildings.

As for the case of energy performance of systems, BEAM gives credit for
the inclusion of particular equipment that provides for improved energy
performance but account for which is not included in the estimation of
annual energy use.
