Sustainable Housing Delivery for The Urban Poor in Nigeria: Literature Findings (Published)
The plight of the urban poor towards achieving adequate and satisfying housing accommodations remains a recurring decimal in Nigeria. Previous housing policies, concepts, strategies, and initiatives failed to establish a long-term sustainable housing delivery for this particular urban populace with recurrent quality and quantity shortages. This article underlines the challenges facing housing delivery for the urban poor and the need for appropriate and timely developmental strategies to ensure sustainable and effective housing delivery in Nigeria. It examines housing policies, housing conditions, and the constraints of sustainable housing delivery for the urban poor through a systematic review of academic outputs. It was discovered among others that sustainable housing delivery for the urban poor in Nigeria is challenged by the factors of incessant and unmatched urbanization, lack of socio-cultural considerations, economic realities, neglect of urban core, and inappropriate housing policies among others. The paper contributes to the body of knowledge on housing delivery from the perspective of the urban poor and concludes by highlighting some recommendations that are likely to obliterate the challenges identified and discussed.

Advances in Building Environmental Sustainability Assessment Tools/Methods and the Nigeria Context: A Review (Published)
Improving the environmental performance of buildings is increasingly gaining global attention of researchers, policy makers/government agencies and the construction industry. This is because the construction industry as emerging sector is highly active in both developed and developing countries and responsible for the high level of carbon dioxide emissions and energy consumption especially in countries described as emerging economy. However, measuring the environmental performance or sustainability of buildings in developing countries like Nigeria, is relatively new and the practice of measuring sustainability is largely based on declarations that come from self-assessed developers and building material producers. The assessment methods, either environmental or performance-based are under constant evolution in order to surmount their various limitations. However, two main assessment approaches can be identified or distinguished: qualitative assessment methods and quantitative assessment methods. The field of environmental assessment methods/tools for buildings is vast, the aim of this paper is to clarify that field by analysing the terminologies and categorising existing tools in the context of the Nigerian building industry.

Ventilation for Comfort in Passive Residential Living Spaces in a Warm-Humid Urban Environment (Published)
The natural ventilation provision for comfort in selected residential estate buildings in Ibadan, Nigeria was assessed in this paper. This was with a view to assessing the indoor air movement for comfort and sustainability of passively operated urban living spaces within a warm-humid climatic environment. Systematic sampling was used to select 91 buildings from the 273 in the estate. The ventilation analysis indicated that the living-room spaces in the buildings had adequate comfort ventilation with the average indoor wind speed obtained ranging from 0.21m/s to 0.24m/s. In the comfort survey it was found that 82% of the total votes of the respondents were within the comfort zone and 72% of the respondents preferred their naturally ventilated spaces to air-conditioned spaces. The buildings were adjudged to be comfortable and sustainable since they operate passively and are maintained at no extra cost to the users.

IMPROVEMENT POWER FAILURE AND PROTECT SUSTAINABILITY OF THE ENVIRONMENT IN BANGLADESH BY THE RENEWABLE ENERGY: REVIEW (Published)
Developing countries are without compromising the environment, environmentally friendly, economic development of Bangladesh is a burning issue and requires a large supply of power. The use of fossil fuels is limited, solar, wind; biomass renewable energy sources such as hydro power limit option might be compensated for the other countries of similar power crisis in Bangladesh are not separated. From the power supply grid connected through three quarters (76%) of the people of Bangladesh. No doubt it is natural gas that has been limited to using a variety of purposes. Mean energy demand alarm output gap is expected to increase exponentially. Despite expectations that renewable energy sources are now in this country, you only have a 0.3% share of renewable energy in the total energy supply. In this article, not only, however, for future use in Bangladesh and the state of renewable energy that can be obtained in Bangladesh to review the renewable energy technologies. It will also try to show that the direction of future research, the use of renewable energy to meet future needs.
