Abstract
Rural to urban migration has been a disturbing factor in Nigeria. The urban cities have become over populated resulting into poor provision of comfortable and healthy accommodation for the citizenry. The menace has further metamorphosed into complex units of socio-economic and cultural degradation, increasing youth unemployment, poor housing delivery, and depletion of the ozone layers due to carbon dioxide emission from small electric generators called “I pass my neighbor”. The situation is no longer convenient to be curtailed because of the limitations of the existing institution to provide mechanism to curtail the growing challenges. This indicates a factor of undermining urban poor of affordable and decent housing, which makes them “homeless. The research aims at conveying into luminance the drivers of low energy materials that could be employed through sustainable measures to deliver public housing in Nigeria. The objective brings forth considerations for application of low energy materials that can be integrated at the design stage to reduce the energy used in achieving comfort and limit the overall energy consumption of residential buildings in Nigeria. The purpose is to make public housing affordable and sustainable in Nigeria. The study employed the use of qualitative data analysis from relevant literatures. The results obtained indicate the high energy delivery in Nigeria’s public housing reflects the overgrowing poverty level in the country. The population living in poverty has remarkably grown from 1980-2010. This factor has made it difficult for the majority poor populace to own a house due to the high cost involved in obtaining a high energy material for building construction. The study recommends a drift to low energy materials, which involves lesser energy of production and are locally found in the country, and tends to provide affordable housing to the poor living in urban centers. Hempcrete, cob, raw earth, sheep wool, bamboo, rice hull, wattle and daub, rammed earth, the mud, adobe, fire brick, are available traditional building materials with low energy richly found in Nigeria, government and private developers should adopt them in construction of dwellings to curtail the limited provided accommodation for the increasing population in urban centers and to provide decent, affordable, and sustainable accommodation to Nigerians.
Highlights
The need for shelter by individuals is one aspect of living that keeps evolving as man and society changes
That means more of adobe and cement would produce numerous quantity within little energy inputs while concrete and fire bricks requires more of energy to produce a desired quantity
When such is put in practice, affordable public housing would desire more of cement and adobe to fire brick and concrete
Summary
The need for shelter by individuals is one aspect of living that keeps evolving as man and society changes. 50% of Nigeria’s 160 million citizens which are low income earners in urban centers are mostly affected by the unhealthy condition of the polluted environment and slaking economy to afford a healthy living. 20 Jonam Jacob Lembi et al.: The Drivers for Low Energy Materials Application for Sustainable Public Housing Delivery in Nigeria attributes of urban centers all over the country. According to [17] estimated the urban and rural areas housing needs in the country at total demand of 16-17 million units with an average cost of 2.5 million naira per housing unit, this identifies that Nigeria requires 35 trillion naira to finance the housing deficit of 14 million housing units. Sustainable architecture involves the use of various research-driven unique construction materials to achieve specific energy efficient goals [21]
