NTRODUCTION
BEAM encourages detailed design of buildings and systems, with
provisions that enhance energy efficiency and energy conservation.
Credits are awarded on the basis of enhanced energy performance, the
provision of energy efficient systems and equipment, and provisions for
energy management.

LASSIFICATION OF
B
UILDINGS
To deal with the wide range of buildings that may be encountered,
buildings/premises are categorised according to the provisions for air-
conditioning and ventilation. This is necessary as the operational needs
of buildings together with the different air-conditioning and ventilation
systems that serve their needs result in large variations in energy use
between buildings.

CONDITIONED
B
UILDINGS
This refers to buildings and premises that are air-conditioned, either by a
central plant serving the entire building or unitary equipment for
individual spaces, and where the air-conditioning system operates
almost throughout the year. When a significant portion of such buildings
are mechanically or naturally ventilated additional assessments shall be
included.

B
UILDINGS
This refers to buildings that are designed to use natural ventilation, but
may be air-conditioned when natural ventilation fails to provide adequate
indoor comfort conditions. When a significant portion of such buildings
are mechanically ventilated additional assessments shall be included.

ECHANICALLY
VENTILATED
B
UILDINGS
This refers to buildings such as car parks, factories, godowns, etc.,
where the major areas rely solely on mechanical ventilation for indoor
thermal environment and/or control of air quality. When a significant
portion of such buildings are air-conditioned or naturally ventilated
additional assessments shall be included.

B
UILDINGS
This embraces buildings/premises that cannot be categorised as one of
the above and comprise an unusual mix of premises or premises with
special uses. Such buildings would be assessed based on either the
generic framework for assessment of energy performance, with the
required parameters and benchmarks determined as the first stage of the
assessment, and/or feature specific assessments.
A
SSESSMENTS
The energy use assessments take account of the specific characteristics
of the building development, such as the type and usage of premises it
houses and the range and operational characteristics of the systems and
equipment required to meet the needs of users, and comprise three
parts:
•
estimated Total Building Annual Energy Use (and where appropriate,
Maximum Electricity Demand) for heating, cooling, lighting,
equipment small power, etc.;
•
features and performance of specific systems and equipment; and
•
testing and commissioning of systems and provisions that facilitate
energy efficient management, operation and maintenance.
