What is the maximum U-value for external walls?

The maximum U-value for external walls refers to the measure of thermal transmittance, indicating how effectively a building element conducts heat. A lower U-value signifies better insulation, which is crucial for energy efficiency and comfort within buildings.

In the context of Estidama, which emphasizes sustainability and resource efficiency in construction and design practices in Abu Dhabi, the maximum U-value for external walls is indeed established to promote thermal performance and minimize energy consumption. The value of 0.57 W/m².K aligns with guidelines that prioritize maintaining a balance between energy efficiency and practical construction applications, allowing for a reasonable level of thermal insulation while also considering the climatic conditions typical of the region.

This maximum U-value is critically established to ensure that buildings can maintain desired internal temperatures with minimal reliance on mechanical heating or cooling systems, leading to reduced energy consumption and lower carbon emissions over the building's lifecycle.
