*2.3.6 Innovation and regional priority*

These are additional requirements in the LEED rating system. Innovative design and construction practices is meant to improve the quality of the building and increase user satisfaction. Implementing green building practices requires innovation there are few LEED accredited professionals in Nigeria since Nigeria is yet to develop its policy for green building development. Design professionals are reluctant to adopt green technology, materials, and resources necessary to reduce the cost of green building development. The requirement for regional priority is to encourage every country to prioritize the immediate environmental, social and economic conditions. Nigeria has a tropical climate. The southernmost part of the country is affected by monsoon rainfall and is characterized by rainforests and mangroves, the country's middle belt has a tropical savannah climate and the most northern part of the country is arid and hot. Most parts of the country have seen a reduction in rainfall. The government estimates a decrease in average temperature across the country [13]. The south, is affected by changes in timing and duration of the raining season while the northern region is experiencing a steep rise in the frequency and duration of drought. This regional variation in climatic condition holds significant for green housing development in Nigeria. The use of prototype buildings across the various climatic zones in the country have not achieved the desired result. Green housing provides that climatic and environmental conditions of each country, region or state is prioritized in design and construction of housing.
