He conducted Joint Admissions and Matriculations Board JAMB (the Board responsible for admission into Nigerian universities) examinations for four years as JAMB UTME Coordinator for Ihiala, Nnewi, Igbariam and Awka South. As a Unionist, he was Secretary, Academic Staff Union of Universities (ASUU) Educational Advancement Committee, and at National level, he was Secretary of ASUU Welfare and Gender Committee. He was Architect/Member of the Federal Government’s National Implementation Working Committee for the Entrenchment of Entrepreneurship Education in All Nigerian Universities. He also served the Nigerian Institute of Architects variously as Member – Practice Committee, Student Affairs Committee, Library & Publications Committee, and Competitions & Exhibitions Committee.

Widely travelled, he has visited universities in Ireland, United Kingdom, USA, Kenya, Ethiopia, Ghana and Benin Republic.  He is currently a PhD Scholar at the Institute of Architecture, Â鶹´«Ã½, Leicester, United Kingdom. He is married to Mrs Sussan Maduabum and they are blessed with children.

PhD Title

INDOOR THERMAL EVALUATION OF CLASSROOMS BUILT WITH COMPRESSED EARTH AND SANDCRETE BLOCKS IN ANAMBRA STATE, NIGERIA

PhD project abstract

Local building materials have been widely researched and analysed by Nigerian built environment professionals during the past three decades. This burden has spawned several works by Nigerian academics on local materials as alternative building materials. Findings from studies show that building materials constitute 50% to 65% of the cost of a building and that the wall contributes a major part (22% of the cost of a building). Most of these studies suggested earthen blocks as an alternative to the conventional sandcrete blocks (a mixture of sand, cement, and water) commonly used in Nigeria and some West African countries. The Government of Nigeria initiated a policy that established burnt brick factories in all the then 12 states of the country by 1975, but this scheme failed because the bricks turned out to be more expensive than the sandcrete blocks they were meant to challenge because cement, the main component, was imported and therefore expensive. 

Aside from cost, the matter of global warming raised concerns about the sustainability of sandcrete being tied to cement, which has been identified as a heavy emitter of greenhouse gases (GHGs). This led to a further search for a more environmentally friendly walling material, and the ancient earthen material was once again suggested as a suitable alternative. The mechanical properties of earth: wetness (it expands when it absorbs water and contracts when it dries up); poor tensile strength (which limits its use without support); and brittleness (which makes it produce dust and wear away easily) led to its decline. Aside from the properties of earth, the establishment of 5 cement plants in Nigeria between 1957 and 1964 made earthen buildings less attractive since cement then became affordable. To deal with these mechanical problems, the Stabilised earth block technology was gradually adopted. Even then, earthen buildings still suffered from a negative perception of being cheap, weak, and obsolete. Furthermore, beyond stabilisation, the building industry kept experimenting with various concepts related to earth, and this led to the introduction of the interlocking block press. Interlocking block construction, sometimes called “dry stack” construction (because it largely eliminates mortar), introduced some advantages in walling, such as shorter construction time, a reduction in the skills demand, and stability, considerably reducing the cost of construction. The problems of sandcrete, the popular, widely used block across West Africa as identified in some writings, include cost (related to cement), carbon footprint, and energy efficiency, as have been noted in the preceding paragraphs. Previous studies concentrated mostly on the cost of production of the building and not the cost of occupancy, which will bring up energy use. A few have dealt with embodied energy, but hardly any have studied the indoor thermal environment. Furthermore, most of the studies have covered residential buildings, but little work has been undertaken on other building types like office buildings, hospitals, school buildings, and commercial buildings. This research is specifically on classrooms built with the two different walling materials in the same location to ascertain the indoor thermal conditions that occur in the two types of classrooms, respectively. Nigeria is vast and diverse, with six distinct climatic zones; therefore, any climate-based study has to be specific to a particular zone. The 5 states of the south-east geopolitical zone of Nigeria—Abia, Anambra, Ebonyi, Enugu, and Imo—have been found to present uniform climate characteristics, so the findings of this study will also apply to all 5 states.
