Saudi Energy Code SG-01: Insulation and Glazing Requirements Explained

The Saudi Energy Code (SG-01), developed by the Saudi Energy Efficiency Center (SEEC), is a mandatory building energy code that sets minimum thermal performance requirements for all new construction and major renovations in Saudi Arabia. Understanding these requirements is essential for architects, engineers, and contractors to ensure permit approval and avoid costly retrofits.

Saudi Arabia's Climate Zones for Energy Code Compliance

Saudi Arabia is divided into four climate zones under SG-01, ranging from the hot-dry interior (Riyadh, Qassim) to the hot-humid coastal regions (Jeddah, Dammam). Each zone has different minimum thermal performance requirements, with hotter zones generally requiring higher insulation values. Always verify which climate zone your project falls in before specifying materials.

Minimum Roof Insulation Requirements

Saudi Energy Code requires minimum roof insulation thermal resistance (R-value) of R-19 to R-25 depending on climate zone. In practical terms, this typically requires 75-100mm of EPS, XPS, or mineral wool insulation above the structural roof slab. This is one of the most critical code requirements given that solar radiation on flat roofs is the primary source of heat gain in Saudi buildings.

Minimum Wall Insulation Requirements

External walls must meet minimum R-values of R-11 to R-13 in most Saudi climate zones. A standard 200mm hollow CMU block wall has very low thermal resistance and typically requires an additional 50-75mm insulation layer to meet code. AAC block walls of 200-250mm thickness can potentially meet code without additional insulation due to their superior intrinsic thermal performance.

Glazing Performance Requirements

Windows must meet maximum Solar Heat Gain Coefficient (SHGC) values of 0.25-0.35 depending on window orientation and climate zone. This generally requires solar control glazing — either single glass with a high-performance solar control coating or double-glazed Low-E units. Standard clear glass, which has SHGC of 0.86, cannot meet Saudi Energy Code requirements.
