Which construction method is introduced in the 2024 Building Code for buildings up to 18 storeys high?

The introduction of encapsulated mass timber construction in the 2024 Building Code for buildings up to 18 storeys signifies a progressive shift towards utilizing sustainable materials and innovative design practices in high-rise construction. This method not only promotes the use of renewable resources but also enhances the aesthetic appeal and thermal efficiency of buildings.

Encapsulated mass timber construction involves using engineered wood products that are designed to resist fire and structural loads. This technique incorporates mass timber elements that are protected with non-combustible materials, enabling them to meet safety and performance standards for higher tall buildings. The combination of strength, sustainability, and speed of construction makes this method an attractive option for developers looking to comply with modern building codes while addressing environmental concerns.

The other construction methods listed do not align with the latest regulatory framework aimed at facilitating higher-density development. Conventional wood frame construction generally limits height and cannot meet the structural demands for taller buildings, while prefabricated steel construction and reinforced concrete construction, although effective, are not the specific innovations introduced for this purpose in the 2024 Building Code updates.
