Leadership in Energy and Environmental Design (LEED) is an internationally recognized green building certification program developed by the U.S. Green Building Council (USGBC). The framework evaluates the environmental performance of buildings through a structured scoring system that considers energy efficiency, water conservation, sustainable materials, indoor environmental quality, and site sustainability. Buildings that meet the criteria can achieve certification levels including Certified, Silver, Gold, and Platinum.

In Sri Lanka, the construction sector has shown increasing interest in sustainable building practices as developers seek to improve operational performance and reduce environmental impacts. Hotels, office buildings, healthcare facilities, and mixed-use developments are among the projects that may explore sustainability certification frameworks. LEED certification is often used in international projects where environmental performance documentation is required.

The LEED certification process includes sustainability planning, energy modeling, environmental analysis, and documentation submission. These stages require coordination between architects, engineers, contractors, and sustainability specialists. Because of the technical requirements involved, many project teams work with experienced sustainability consultancies that guide them through the certification process and help integrate environmental strategies into building design.

The following consulting firms provide LEED advisory services and sustainability consulting relevant to projects in Sri Lanka.
