LEED is a green building certification program used worldwide, providing a framework for healthy, efficient, carbon and cost-saving green buildings and is applicable to all building types and phases, including new construction, interior fit-outs, and operations & maintenance. (Latest update in 2024 continues to emphasize energy efficiency and sustainable materials.) LEED v4.1 is the most current version, emphasizing improved performance and outcomes in buildings. The LEED rating system addresses various aspects of sustainability, including energy efficiency, water conservation, material selection, indoor environmental quality, and innovation in design.

OSHA sets and enforces protective workplace safety and health standards, ensuring safe and healthful working conditions for workers by setting and enforcing standards and by providing training, outreach, education and assistance. (The most recent updates in 2024 focus on fall protection, hazard communication, and respiratory protection.) OSHA standards are designed to prevent workplace injuries and illnesses. They cover a wide range of hazards, including exposure to toxic substances, fall hazards, electrical hazards, and machinery hazards. Employers are required to comply with all applicable OSHA standards.

The ADA sets standards for accessible design in new construction and alterations to ensure that facilities are readily accessible to and usable by individuals with disabilities. (Updated guidelines as of 2024 ensure that public accommodations and commercial facilities are accessible to individuals with disabilities.) These standards cover a wide range of elements, including accessible routes, entrances, restrooms, parking spaces, and signage. Compliance with the ADA is essential to avoid discrimination and ensure equal access to opportunities for people with disabilities.
