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.

The estimation of annual energy use and maximum electricity demand
takes into account design improvements to the building envelope and the
efficiency of air-conditioning and lighting systems and equipment and
etc. It shall cover all aspects of energy use in buildings. BEAM credits
additional measures address further energy efficient system.
Passive building design allows buildings to respond to the local climate;
reducing the reliance on active servicing for human comfort, which in turn
reduces energy consumption and associated carbon dioxide emissions.
There is an alternative route to asses these elements for residential
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. The use of robust automatic controls has been shown to
provide for energy conservation through ‘switching-off’ or ‘turn down’.
