ABSTRACT 

                                                                                                                                       Building Integrated Photovoltaic (BIPV) is a multifunctional building element which performs the dual function as an integral component of a building (such as roof tiles, BIPV skylight, glazed facade) and at the same time generate electrical energy without the need for additional space and emission of carbon. It has served as a tool for designing energy efficient and sustainable buildings with ability to create a conducive micro-climatic environment where visual, thermal and acoustic comforts are attained through reduced energy cost with little or no negative impact on the environment.  Among other factors the energy generating potentials of BIPV depends on the available insulation on building site, and its form, orientation and inclination of deployed building component.  This research quantifies the energy generating potential of BIPV systems on rooftops of lecture theatres in MAUTECH, Yola, Nigeria. All  the lecture theartres of the Univeristy were  subjects of the study, based on logical argumentation. A checklist on varialbes of BIPV was generated for the LTs and a mathemathecal model was used in relation to the climatic data of Yola to calculate the energy potentials of rooftops of the  lecture theatres. It was found that an average of about 50% of the roof area of the LTs if covered with BIPV system is capable of generating the total energy need of the building. It was also found that LTs with flat roof have more potential of generating solar power than hipped roofs.

ABSTRACT 

                                                                                                                                           The study examines environmental problems and adverse impacts on the health of urban households in the Lafia metropolitan area, Nigeria. The results showed that majority (50%)of the respondents in Tudun-kauri disposed solid waste in open dumps and allow it to decompose naturally while (24.8%) others use burning as the way of disposed their solid wastes. Poor handling, evacuation and disposal of waste have numerous negative impacts on the environment such as proliferation of mosquitoes and flies, bad odour, visual pollution. These negatives impacts on the environment in turn have negatives impacts on the health of the residents. Dysentery and diarrhea (81%) appears the most encountered disease followed by Malaria (78%) and cough and sore throat (36%) among others. The major causes for the inefficient solid waste management systems in Lafia are the lack of social awareness/ community involvement and sound legislative policy. There is a need for greater government involvement, community participation and orientation with private sectors involvement in waste management in Lafia with a view to building capacity for effective delivery of waste management services and ultimately improve the sanitary state of the city thereby reducing preventable disease burden on the populace as. It is recommended that Nasarawa State environmental protection agency (NSEPA) should introduce house to house sanitary inspection, monthly environmental sanitation with strict penalty against defaulters. Other recommendations if strictly put to use, it will go a long way reducing the menace posed by solid wastes to human health and his environment.

ABSTRACT

The paper argued that road traffic accidents information collected from field survey can be used in reducing and preventing road traffic accidents. The study investigated causes and black spots of road traffic accidents in Minna. Information on accident such as place of accident, type of accident, and nature of accident were sought through field survey, and the descriptive analysis was use with Geographical Information System (GIS) to conduct the study. The result of the analysis shows that, on type of accident, motorcycle is rank 1^st with 19.9%, followed by car 17.0%, tricycle 4.8%, pedestrian 4.5%, bus 4.2%, and truck 2.1%. On nature of accident, 27.9% nature of accident is inside vehicle, and 24.1% nature of accident is hit by a vehicle. And the black spots of road traffic accident in Minna are Bosso, Kpakungu, and Tunga which are centrals of economic activities in Minna. The study finally uses information from the accident survey as a basis for reducing and preventing road traffic accident. And recommendations are made on sustainable economic empowerment, and decentralization of centers of economic activities as a way of reducing and or preventing accident in Minna.

ABSTRACT

A study on the concentrations and daily variations of SO₂ and H₂S in the waste dumpsite at Osisioma Ngwa Local Government Area, Abia State, was carried out using some hard hold air quality monitors. Results of SO₂ and H₂S obtained for morning and evening hours reading during the dry season to be for Umuigwe dumpsite SO₂(0.04:0.07), H₂S (0.70:0.30); Umujima dumpsite SO₂(1.37: 1.52), H₂S (0.80:0.30); Niger Stone dumpsite SO₂(1.62:0.04), H₂S (3.40:0.30); Uratta Amaisa dumpsite SO₂(0.09:0.04), H₂S (0.60:0.30); Eyimba market dumpsite SO₂(0.13:1.34), H₂S (0.10:0.91); Asaeme dumpsite SO₂(0.06:0.08), H₂S (0.34:0.90);  and Owerrinta control location SO₂(0.02:0.01), H₂S (0.03:0.03). When comparing results with permissible maximum standard values obtained indicated air quality to be within good to moderate ambient air quality descriptions. However, the concentrations were higher with WHO recommended standard for SO₂ and H₂S emission. This indicates that the study area can be described to have poor air quality and which can be dangerous to human health.

ABSTRACT

Theoretical and empirical studies have considered the importance of conflict management as a factor of change realization, motivation and improvement of work performance effectively and efficiently. This study investigated approaches to conflict management in building construction industries in Adamawa state. The population for this study was 500 people. 20%of the population was taken which gave a sample size of 100 respondents. They included contractors, site and project managers, engineers, consultants and labourers. A structured questionnaire was used for data collection and the data was analysed using means and standard deviation. The findings of the study revealed that, conflicts possess a high negative effect in building construction industries and solutions to these conflicts as to its effects and frequent occurrence in building construction industries, seem insufficient to critically handle these effects efficiently. The findings reveals that amongst others,  effective management of available resources and proper inventory of residual, used and needed items on the site as well as adherence to design specification and instructions of site engineers and tolerance amongst workers should be basis of conformity to job engagement, and be employed as fundamentals for conflict management.

ABSTRACT

The paper identified materials management as an ingredient to reducing total construction cost since cost of materials account between 40% to 70% of the total cost of construction. Materials cost control activities are therefore, directed mostly towards selection, purchase, storage, and consumption of materials. It can also be very effective if it involves the cooperation of various departments such as: Purchasing, receiving and inspection, and stores, production and stock control department. The research also discussed storing procedure and materials cost price. Therefore, materials management is a function responsible for coordination of planning, sourcing, purchasing, moving, storing, and controlling materials in an optimum manner so as to provide predetermined services to the client at a minimum cost. Store keeper should be appointed on any construction site, the location and layout of stores should be decided very carefully to minimize multiple materials handling, materials brought to site should be accounted for on a daily basis.

ABSTRACT

Water is a basic need of all humans and its accessibility, an important component of human development. Accessibility to safe water is a major concern to every responsible government at local, State and Federal levels. The Sustainable Development Goal number six aims at making water available for all by 2030. Even so, the national water coverage at the end of 2015 (Millennium end-year) was 69% in Nigeria (USAID, 2016). The water board/corporations in Nigeria with the statutory mandate of providing safe drinking water for the people have not been able to do so effectively, hence, the development and proliferation of alternative sources of water including boreholes and wells to meet up with the water need of the people in urban areas. This research examines the contribution of boreholes and wells in meeting the overall water need in Suleja area, Primary data was collected through the use of Global Positioning System (GPS) to record the coordinates of the identified boreholes and wells in each district making up Suleja area. A total of 1124 sources were identified in the area made up of 474 boreholes and 650 wells. The total volume of water supplied by these sources is 2,674,500liters/day representing 17.74% of the total water need by a population of 264, 506 persons in Suleja area (2016 projected population), at 60ltres/capita/day. However, the study recommends that individual landlords and house owners should be encouraged to develop joint mini-water schemes to reduce potential incidences of environmental hazards associated with underground water abstraction and reduce economic stress in digging private individual boreholes and wells.
