Building Professionals’ Perspectives on the Implementation of Green Building for Climate Change Mitigation in Nigeria (Published)
The building and construction sector is responsible for as much as one third of total global green house gas (GHG) emissions and about 80 percent of these emissions take place during the operational phase of buildings. This results in damage and destruction of buildings and infrastructure, delayed construction and increased costs. Through the practice of green building, these emissions especially CO2 can be significantly reduced in both developed and developing countries. The green building concept considers many ways that building services ner aq as well as other GHG impacts associated with the built environment, including the effects of alternative urban designs, the use of on-site power generation and life-cycle GHG emissions from building construction, materials, and equipment. This study reviewed green building practice in developed countries considering building professional’s perspectives of climate change mitigation in Nigeria through green building and found that despite the many benefits of green building such as enhancement of the comfort and health of occupants, improvement in air quality, occupants‟ satisfaction, reduction of aggregate future capital and maintenance costs, creation of job opportunities in the construction industry and protection of the ecosystem among others, there are numerous obstacles that prevent these benefits from being achieved. Some of the obstacles are lack of green building awareness by developers, unavailability of green building materials locally, lack of policy or guidelines for green building, and lack of adequate knowledge and technical know-how of green building among building professionals. It recommends public enlightenment of green building by government and non-governmental organizations, request for green building guidelines, and funding for green building research, development and implementation.

Building Collapse in Nigeria: The Causes, Effects, Consequences and Remedies (Published)
Building collapses in Nigeria have been on the increase in recent times. There are frequent media reports of collapsed of buildings in major Nigerian cities like Lagos, Abuja, and Port Harcourt, etc and other parts of the world. In an attempt to find lasting solutions to tackle the challenges, this paper examines causes of building collapse in Nigeria and also enumerated specific areas the stakeholders in the building industry and the general public are affected. The problems range from faulty design, negligence, incompetence, faulty construction, foundation failures, extraordinary loads and corruption. Forces of nature were also identified as part of causes of building collapse. Some recommendations were made as part of lasting solutions to tackle the challenges.
