Adoption of LEED® as a Green Building Rating System in Nigeria Going Green In Nigeria
Green building rating systems are in a state of constant flux and often differ from region to region. Regardless, fundamental principles persist from which the rating system is derived. These include sustainable sites and structure design efficiency, water efficiency, energy efficiency, materials efficiency, indoor environmental quality, operations and maintenance optimization, innovation and design process, waste and toxic reduction etc. The essence of green building is an optimization of one or more of these principles. The green building rating system, LEED® (Leadership in Energy and Environmental Design), a designation developed by the United States Green Building Council (USGBC), which is the dominant system in the United States and Canada, is a strong contender for adoption in Nigeria for it encourages and accelerates global adoption of sustainable green building and development practices through the creation and implementation of universally understood and accepted tools and performance criteria. LEED-based green design not only makes a positive impact on public health and the environment, it also reduces operating costs, enhances building and organizational marketability, potentially increases occupant productivity, and helps create a sustainable community. Currently, there are nine (9) LEED® rating systems to address various project types such as; * LEED for New Construction (NC)
* LEED for Existing Buildings: Operations & Maintenance (EB: O&M) * LEED for Commercial Interiors (CI)
* LEED for Core & Shell (CS)
* LEED for Schools (SCH)
* LEED for Retail
* LEED for Healthcare (HC)
* LEED for Homes
* LEED for Neighborhood Development (ND)
LEED® certification is a credit-based rating system, with different levels of certification awarded for various tiers of credits earned. Each credit is intended to address a specific environmental impact of a building. The number of credits generally determines the number of achievements. Certification is granted solely by the Green Building Council responsible for issuing the LEED system used on the project. LEED® is not only the U.S. market leader, but is also the most widely used rating system by Federal and State agencies, which makes it easy to communicate sustainable design achievements with others.

Green building (also known as sustainable building) refers to a structure and using process that is environmentally responsible and resource-efficient throughout a building's life-cycle: from siting to design, construction, operation, maintenance, renovation, and demolition. This is particularly relevant today with the supply of the world’s fossil fuel rapidly dwindling, the concerns for energy security increasing, and the impact of greenhouse gases on our climate rising; there is a dire need to find ways to reduce energy loads, increase efficiency, and employ renewable energy resources in our facilities.
Green building is environmentally friendly because it uses sustainable, location- appropriate building materials and employs building techniques that reduce energy consumption. Indeed, the primary objectives of sustainable design are to avoid resource depletion of energy, water, and raw materials and prevent environmental degradation caused by facilities and infrastructure throughout their life cycle. Likewise, it places a high priority on health, which is why green buildings are also safe, aesthetically pleasing, and comfortable. In addition to the classical building design concerns – economy, utility, durability, and delight – green design...
