in Dubai including Free Zone regulators and other third parties.
102.02 Energy Compliance Method
There are two compliance routes for energy performance in buildings. The standard
method is referred to as the Elemental Method; the alternative method is referred
to as the Performance Method.
a) Elemental Method: All buildings must comply with each of these regulations.
b) Performance Method: Alternatively, a calculation method may be employed for
a building which may not comply with all the elemental requirements of those
Articles listed in Table 102.2 (1).
The Performance Method, using a calculation tool such as dynamic thermal
modelling, must compare the annual energy consumption of the proposed building
with that of a reference building which meets all the elemental requirements
listed in Table 102.2 (1). The reference building must be equal in shape, size and
operational patterns to the proposed building.
Compliance with the Green Building regulations will be demonstrated if the annual
energy consumption of the proposed building is equal to or lower than the annual
energy consumption of the reference building.

water efficient fixtures detailed in Article 601.01.
The Performance Method, using a calculation tool, must compare the annual
water consumption of the proposed building with that of a reference building
which meets all the elemental requirements detailed in Article 601.01. The
reference building must be equal in shape, size and operational patterns to the
proposed building.

average thermal transmittance (also known as U Value) and Shading Coefficients
(SC) that does not exceed the values specified and Light Transmittance greater
than or equal to the values specified.
A. External Walls, Roofs, and Floors:
Building elements forming the external walls, roofs, and floors (where one side
of the floor is exposed to ambient conditions) must have an average thermal
transmittance (U Value) which does not exceed the following values:
Roof U= 0.3 W/m2K
External Wall U= 0.57 W/m2K
If the floor is in contact with the ground, the insulation should only be applied to
one meter (1m) in from the perimeter of the building.
Glazed elements with back insulated panels must be treated as walls (and therefore
must meet the performance requirement for walls).
B. Glazed Elements - Fenestration:
1. If the total area of external walls that let in light is forty per cent (40%) or less
of the external wall area, then the glazing elements must meet the following
performance criteria:
Thermal Transmittance (Summer U value) U= 2.1 W/m2K (max)
Shading Coefficient (SC) 0.4 (max)
Light Transmittance 0.25 (min)
2. If the total area of external walls that let in light is between forty percent (40%)
and sixty percent (60%) of the external wall area, then the glazing elements must
meet the following performance criteria:
Thermal Transmittance (Summer U value) U= 1.9 W/m2K (max)
Shading Coefficient (SC) 0.32 (max)
Light Transmittance 0.1 (min)
