LEED (Leadership in Energy Environmental Design) là một giấy chứng nhận cho các công trình xây dựng xanh được cấp bởi Hội đồng Công trình xanh Hoa Kỳ (USGBC) ra đời năm 1995 tại Mỹ. Đây là tiêu chuẩn quốc tế tiên phong về vấn đề xây dựng các công trình tiết kiệm năng lượng và bảo vệ môi trường sống của con người.

• To support high performance, cost effective project
outcomes through an early analysis of the interrelationships among systems
• Perform a preliminary simple box energy modeling
analysis (site consitions, building envelope, lighting levels,…)
• Perform a preliminary water budget analysis (indoor,
outdoor water demand, process water demand, supply sources)
• Document how the above analysis in the owner’s
project requirements and basic of design.
