Energy Efficiency Building Regulations
7 countries have mandatory EE Building Regulations 8 countries have voluntary EE Building Regulations
8
By Building Type
• New & Existing Buildings: Bahrain, Kuwait, Saudi Arabia and Dubai
• New & Extension of Existing Buildings: Egypt, Jordan & Tunisia
• New Buildings: Syria
9
Climatic Zones
• Countries identified one to three climatic zones
• How countries reflected different climatic conditions in their EE building regulations?
– Egypt & Tunisia: different thermal resistance values for the building envelope elements
– Kuwait: different minimum regulations for air-conditioning systems for the two different climatic zones: coastal and interior regions
– Syria: different thermal resistance values of the external surfaces of roofs and exterior walls according to three wind speed categories of different locations in Syria - ?
11
Passive Building Components
Most EE building regulations set requirements for the thermal resistance
of the building envelope
However, only few countries have specifications for other passive
building components

Active Building Components
14
Saudi Arabia: no EE requirements for most active building components
Tunisia: all EE requirements for active building components are voluntary
Active Building Components
18
General Recommendations
• Mandatory with proper enforcement procedure
• Quantifiable measures for easiness of implementation
• Climatic zones need to relate to energy consumption of the building (heating, cooling, dehumidification)
• Scope of application: wide coverage of buildings
• New vs. refurbishment of existing
• Differentiate EE requirements for new buildings and existing buildings
• EE requirements should cover all building passive & active components
• Consider mandatory for cost-effective RE applications (SWH)
• Provide enabling frameworks for integration of other RE applications in building design
