To support sustainability during construction/reservation, which guidelines should be followed?

The correct choice, which is LEED, stands for Leadership in Energy and Environmental Design. It is a widely recognized green building certification program that provides a framework for developing sustainable buildings. LEED guidelines focus on optimizing energy efficiency, reducing water usage, minimizing waste, and enhancing overall sustainability during the construction and renovation processes. By following these guidelines, construction projects can significantly decrease their environmental impact and improve long-term viability.

Other options, while relevant in different contexts, do not specifically address sustainability in construction and renovation in the same comprehensive way as LEED. ISO pertains to international standards in various fields, including quality management and environmental standards, but it does not specifically focus on the sustainability of building practices. OSHA is concerned with occupational safety and health standards to ensure worker safety on job sites, but it does not address sustainability directly. NEEA, or the Northwest Energy Efficiency Alliance, promotes energy efficiency and conservation in the Pacific Northwest, but it is more of a regional initiative rather than a set of universal guidelines for construction sustainability. Thus, LEED is the most appropriate and focused choice for ensuring sustainability in construction and renovation efforts.
