Item Thermal Comfort Performance of Thermoelectric Peltier Module Refrigeration System in Built Environment(School of Environmental Technology, Federal University of Technology Minna. PMB 65, Minna, Niger State Nigeria., 2024-11-29) Musa Titus Dada; Ejiga Anthony EjigaAccording to data provided by the International Energy Agency, nearly 1.6 billion air conditioning (A/C) systems were operating globally in 2017, accounting for approximately 6% of the overall final energy consumption. To address the energy and economic challenges posed by such extensive use of air conditioning for thermal comfort, it is imperative to identify alternative solutions that can effectively operate in warm-humid environments. This study explored the thermal comfort performance of thermoelectric module refrigeration (TEMR) system in built environment; installed in a single-room facility in Minna, Niger State, Nigeria, over a one-month period. The experimental setup involved a test room measuring 1.3 m x 2.6 m x 3 m, equipped with aluminum roofing, an asbestos ceiling, an aluminum-framed window, and a steel door. The TEMR system was assessed for its ability to regulate indoor temperature and humidity under varying external climatic conditions. The TEMR system operated at a constant current of 6.4A, with data collected at specific intervals throughout each day. Results indicated that the TEMR system significantly reduced indoor air temperature and relative humidity, particularly during peak operational hours (12:00 pm to 2:00 pm). Weekly variations showed temperature drops from 37°C to 22°C and humidity reductions from 60% to 32% within 60 minutes of operation. These findings align with ASHRAE Standard 55-2017 for indoor environmental quality. The study concludes that the TEMR system is effective in improving indoor climatic conditions, offering a sustainable and energy-efficient cooling solution. Its performance, influenced by external climatic factors, demonstrates potential for broader application, particularly in developing regions where long- term, low-maintenance, and environmentally friendly cooling solutions are needed.Item Examination of Rental Default by Commercial Property Occupiers in Minna, Niger State, Nigeria(2022) Zainab Adetoro Folorunso; Rukaiyat Adeola OgunbajoThe effect of rental defaults by commercial property occupiers cannot be overemphasised, as the rate of default is increasing at an alarming rate. Rental default arises when occupiers of commercial properties fail to carry out their obligation of fulfilling the financial requirements as when due. This phenomenon has led to several issues on the part of the property managers and property owners, including delays in mortgage payments, poor maintenance, and a host of other problems. This study investigates the prevalence of rent defaults among owners of commercial property in Minna, Niger state, to stop this unsightly occurrence of rental default and related attendance concerns in commercial buildings. This is done to give property owners in the study region more authority over their decisions. The study used a survey methodology in which 311 residents of 38 purpose-built retail complexes (PBSC) received questionnaires via simple random distribution. The received data was examined using percentage and frequency distribution. The results depicts that 52% of the respondent pay their rents as at when do and 48% defaults in the in payment, this shows that the rent default amongst tenants of PBSC in study area is fair.Item ASSESSMENT OF THE EFFECT OF ROAD PROVISION ON PROPERTY RETURNS IN BOSSO ESTATE, MINNA, NIGERIA.(2022) SULEIMAN YAKUBU; AJAYI M.T.A; ABASS SULE; RUKAIYAT OGUNBAJOThe paper assesses the effect on property investment returns, of public capital investment (budgetary expenditures) on road infrastructure in Bosso Estate, Minna (Nigeria) with the aim of establishing the degree of impact of public capital investment on property investment returns. The paper covers an important policy and practice issue regarding the impact of government spending on the real estate industry. The government is keen to know the areas of greater impact of its expenditures and the extent to which the benefits from the effect may go in enhancing or providing funds (through tax) for new road Infrastructure provision or repair of existing ones as it faces funding challenges in providing new infrastructure or improving existing ones. The beforeand-after case method is employed in the study to the increase in property values (rental and sales). The findings demonstrate that once budgetary expenditure (road reconstruction) occurred, property investment returns in the area increased. The findings serve as the foundation for the government’s decision to provide more funds for budgetary allocations and expenditures connected to the infrastructure for road provision. The findings also estimate the potential for capturing the rise in returns from real estate investments as a potential alternative funding source through property.Item Assessment of void periods in residential buildinds in Minna, Nigeria(UNIVERSITY OF THE WITWATERSRAND, JOHANNESBURG, 2024) Rukaiyat Adeola Ogunbajo; Shien Stephen KumaThe period of void is a major challenge faced by investors in residential buildings in Minna. Re-letting vacant apartments takes a while, and in many cases, newly completed residential buildings experience voids. Therefore at what level of void periods, residential building types are most vulnerable, as well as locational differences are the critical questions that informed this study. Thus, the study aimed to provide an in-depth assessment of void periods in buildings among residential neighbourhoods in Minna, Nigeria. The objectives are to assess the level of void periods, analyse variations across residential building types, and explore neighbourhoodlevel differences in the study area. The study utilized a quantitative research design, employing a structured questionnaire that was distributed to ESVs, LEAs, and property owners who oversee the management of the 1,500 residential units that were selected for the sample in 13 different sted analysis of variance, and the Games-Howell post hoc test were used for data analysis. The findings revealed aggregate mean void periods of 4.87, 5.47, 5.13, and 7.03 months for tenement, 1-bedroom, 2-bedroom, and 3-bedroom residential building types. This outcome varies significantly among the building types across the 13 neighbourhoods in terms of those with high and low void periods. The study concludes that there are relatively high void periods in the Minna residential property market and the need for collaborative efforts towards stemming the tide.Item Influencing Factors of Land Dispute in South West Nigeria(FEDERAL UNIVERSITY OF TECHNOLOGY, MINNA, 2024) Dairo O. Elizabeth; Sule A.I.; Nuhu M. B.; Ogunbajo R.A.In Nigeria, particularly in the South-West, the unpleasant consequences emanating from land ownership disputes such as killings, destruction of properties, ethnic and tribal violence, political protests, and multiple sales of land result in a seeming or assumed ambiguity about the real ownership of the land. It was on this basis that this work comparatively analyses measures adopted in managing land disputes in Southwest Nigeria, with a view to developing guidelines for the most effective and efficient measures. A systematic random sampling method was used in selecting the landowners and lawyers, and a purposive sampling technique was used in selecting the directors in the states. Primary data were collected using a questionnaire administered to 955 landowners, 456 lawyers, and 17 directors. Also, seven experts were interviewed, which was made up of 4 lawyers and 3 directors. Descriptive, chi-square, Anova, content analyses, and case studies were used for the analysis. The findings as regards the overall type of disputes in communities in the south west indicate that 22.5% of the respondents encountered boundary disputes, 21.8% encountered land grabbing disputes, 21.5% encountered community land disputes, 30.6% encountered ownership property rights, and the remaining 13.6% encountered encroachment disputes. The land owners found that greed and lack of love generate land disputes in Ondo State, coownership and idle land in Ekiti State, and poverty and lack of love in Osun State. The lawyer found that encroachment and virgin land cause land conflicts in Ondo, Ekiti, and Osun states. The director found that co-ownership, encroachment, and virgin land cause land disputes in Ondo State, Ekiti State, and Osun State respectively. The study recommended that the government, through its agencies, should look into the establishment and creation of more land resolution agencies to resolve issues around land matters. The government should mitigate the nefarious activities of land officers or community land owners by encouraging them to do the needful.Item Assessment of Public Real Estate Investment Performance in North Central Nigeria: A Literature Review(FEDERAL UNIVERSITY OF TECHNOLOGY, MINNA, 2024) Zakari U. Dodo; Mohammed B. Nuhu; RukaIyat A. Ogunbajo; Adeyosoye B. AyoolaThis paper examines the performance of public real estate investments in North Central Nigeria, focusing on their impact on economic development, infrastructure, and social welfare. A comprehensive literature review was conducted, drawing from recent studies on public real estate investment in developing nations. The methodology is a systematic literature review to assess the performance of public real estate investments in North Central Nigeria. Academic journals, government reports, and conference proceedings from the past decade were reviewed to gather relevant information on the subject. A search was conducted using keywords such as "public real estate investment," "North Central Nigeria," "housing development," "infrastructure," and "economic impact." The findings highlight how public real estate investments contribute to job creation, housing development, and infrastructural improvements.

The paper provides insights into how these investments can be better aligned with community needs for improved social and economic outcomes.Item Potential Impact of Smart Building Elements on Commercial Property Investments in Lagos State, Nigeria(FEDERAL UNIVERSITY OF TECHNOLOGY, MINNA, 2024) Joy E. Omoare; Unekwu J. Adama; Namnso B. Udoekanem; Rukaiyat A. OgunbajoThe impact of smart building elements on commercial property investment in recent years including the landscape of real estate investment has undergone significant transformation across the globe, particularly in emerging economies such as Nigeria. This study explores the potential effect of Smart Building Elements (SBEs) on commercial property investment in Nigeria, as the global narrative of real estate investment has been progressively influenced by the Fourth Industrial Revolution Technologies (Industry 4.0), particularly through the integration of (SBEs). In developed regions like the United States, evidence in literature suggests that investors are securing higher premiums in rents and transaction prices by incorporating technologies such as the smart building elements which include sensors, smart meters, smart security cameras, smart thermostats and smart lighting systems into commercial properties. SBEs address the complex demands of commercial spaces which include enhanced comfort, improved accessibility, heightened security, and efficient energy management. The study methodology is based on a review of published articles in peer-reviewed journals and conferences, accessed from online search engines including Google scholar, ResearchGate and Scispace. Results show SBEs facilitate predictive maintenance, enhance space utilization, achieve significant returns on investment, increase tenant satisfaction and retention. Notably, stakeholders (investors, facility managers and tenants) in the real estate sector are aware and accept SBEs. Nevertheless, predominant literature did not capture the tangible economic impact and the operational benefits SBEs can deliver in Lagos state, Nigeria. This research gap underscores a critical need for in-depth empirical study on how SBEs specifically affect commercial property investment outcomes in Lagos state, Nigeria.Item CHALLENGES OF RENTAL HOUSING AFFORDABILITY BY TEACHERS IN MINNA, NIGER STATE, NIGERIA.(International Anatolian Scientific Research Congress, Kayseri – Turkey, 2022) Falilat Abdulmalik; Rukaiyat Ogunbajo; Sekinat AbdulkareemAffordable housing has become a serious and considerable challenge especially for low incomes households which resulted from continue growth and expansion of the urban centre. There has been a serious threat to rental accommodation in the urban areas especially to certain grade of workers whose income in most cases are based on their salaries. The challenge becomes not only to provide the houses but to make the houses affordable to the average Nigerian worker. The study examined the challenges of rental housing affordability by teachers in Minna, Niger state, Nigeria. Data were collected from 927 teachers between grade levels 07-17 in 20 purposively selected public secondary schools within Minna metropolis. Information were obtained on the annual income, property rental value and challenges of rental housing affordability by teachers in the study area. Appropriate descriptive and inferential statistics were employed in analyzing data collected. The study revealed that there was a positive significant correlation between annual income and property rental value of the teachers, which implies that as long as there is increase in annual income of teachers, property rental value of teachers in the study area will increase. Lastly, high cost of building materials among others is the strongest predictor of rental value and thus a key contributor to explaining the level of rental housing affordability of teachers in the study area. Among other recommendations to reduce the rental values of properties occupied by teachers in the study area, government should implement existing staff housing programme. While implementing this programme, various income groups should be put into consideration. Emphasis should also be placed on low and medium housing units specific for teachers. This will reduce the housing cost thus making it more affordable to many teachers.Item Effect of Demographic Features on Household Residential Mobility in Bida(School of Environmental Technology International Conference 2024 (SETIC 2024),School of Environmental Technology, Federal University of Technology Minna, Niger State Nigeria, 2024) Samuel j.; Kemiki O.A.; Ajayi M.T.A.; Musa H. D.; Olawale A.A.This study examined the impact of demographic characteristics on household residential mobility in Bida, Nigeria. Residential mobility, a critical aspect of urban dynamics, is influenced by various demographic factors including age, income, education level, household size, and employment status. Through a descriptive survey approach, the study administered questionnaires on 385 residents of selected neighbourhoods in the study area with 276 questionnaires, indicating 83.6, returned valid for analysis. The collected data were analysed descriptively with frequency tables, percentage distribution and mean values. Findings of the study indicated a steady pattern of residential mobility across the selected neighbourhoods with high income earners more susceptible to mobility than their low-income counterparts. It was further observed that highly educated and younger households exhibit greater mobility, often seeking improved housing conditions and employment opportunities. In contrast, lower-income households tend to have lower mobility rates, constrained by economic limitations and affordability issues. This implies that economic demographic feature (income, employment and home ownership status) is more effective than social features (age, marital status, religion, cultural and social ties) in determining residential mobility (weighted mean score of 3.55 for social features and 3.66 for economic features). The study highlights the importance of understanding demographic influences on residential mobility to inform urban planning and housing policies aimed at fostering equitable and sustainable urban development by concluding that demographic features indeed influence residential mobility pattern over time. The need for policy formulation, such as improvement of economic possibilities, encouragement of affordable house ownership, and the promotion of education and skill development, are recommended.Item Factors influencing implimentation of safety measures against scaffolding Accidents on construction site(School of Environmental Technology International Conference (SETIC 2024), 2024-11-29) Otaru, S, Abdullateef, A.S.
