Improving Maintenance Conditions Of Residential Buildings And Infrastructure Through Comparative Analysis: A Study Of Housing Development Corporation Estates In Enugu
Get PDFEnugu metropolis has faced high building and infrastructure maintenance needs, whose solutions require the synergy of both residents and facility providers. This is because robust solutions are required as the rate of the population increase could overwhelm the capacity of the residents to cope. The objective of the study was to examine the difference in maintenance conditions of residential buildings and infrastructure between Enugu State Housing Development Corporation (ESHDC) estates in Enugu Metropolis with a view to improving the existing building maintenance practices in the city. Survey design method was applied. A multistage, stratified random sampling technique was adopted in the selection of the sample. Four estates were chosen and representative buildings within these estates were selected. Analysis of Variance (ANOVA) tool was used to test the difference between the ESHDC estates in the Maintenance Conditions of Residential Buildings within them. With p<0.05, the study found that there was a significant difference between the housing estates investigated in the state of maintenance conditions of the buildings. The policy implication of these findings was that for improved building maintenance conditions, the lessons learned from the better performing estates would be used for guidance on achieving better maintenance conditions in the estates that performed poorer. This could also be applied to other estates which are managed in a similar manner
Evaluating Adoption Of Green Concepts In Tourist Resort Development In Calabar
Get PDFRegional development is fueled by tourism. Resorts are charming locations created to provide visitors with a tranquil experience. However, the local culture, community development plans, and the natural ecosystem are all impacted by the construction and operation of resorts. This introduces the concepts of green building, green resorts, and green tourism. Green building lessens its impact on the environment. Green tourism places a higher priority on community benefits, cultural sensitivity, and environmental preservation while green resorts employ green building practices. According to statistics, Nigeria and Africa have not embraced green tourism development very much. The majority of studies concentrated on entertainment and economic factors, leaving a gap in the study of green and sustainable issues. By assessing the adoption of green concepts in Calabar, Nigerian tourist resorts, this study fills that knowledge gap. The obstacles to implementing green building techniques include a lack of knowledge, a lack of funding, a shortage of environmentally friendly products, and a lackluster government effort. The study looks into how widely green ideas are being used in resort construction. Using a quantitative methods design, questionnaires were used to gather quantitative data on adoption levels, Seven hundred questionnaires were sent to resort developers, operators, legislators, and designers. The study\u27s findings showed a low-to-moderate adoption level. According to this study, there is a moderate level of adoption of green building practices. Operators can increase the adoption of green resorts if they are educated of its low operating costs benefits and that eco-friendly travel is preferred by tourist. Particular obstacles to the adoption of green practices have been identified as Costly start off capital (84%) Insufficient incentives (79%) low awareness (68%) Eco-materials are scarce (62%). The discussion is moved from presumptions to data-driven understanding thanks to the quantifiable evidence and practitioner insights it offers. The Recommendations are Government Grants and Incentives, Mandatory Green Policy Framework, Training and Capacity Building, Local Manufacturing of Sustainable Materials, Marketing and Public Awareness and Public-Private Partnerships (PPPs). Future studies should examine the economic benefits of developing green resorts, visitor perceptions, and longitudinal adoption trends
Climate Change And Food Security: Navigating Vulnerabilities And Advancing Resilient, Equitable Solutions
Get PDFThe relationship between climate change and food security is a critical issue amid rapidly changing environmental conditions. Rising global temperatures and erratic weather patterns disrupt agricultural systems, especially in rain-fed farming regions. These changes threaten not only food quantity but also accessibility and nutritional quality. This review paper examines the complex impacts of climate change on food security, focusing on vulnerable groups—women, smallholder farmers, and indigenous communities—whose adaptive capacity is limited by socio-economic inequalities. Beyond food availability, climate change reduces the nutritional value of staple crops, worsening ‘hidden hunger’ and malnutrition in impoverished areas. The study highlights the urgent need for inclusive, holistic strategies that combine climate-resilient agricultural practices with structural reforms prioritising equity and social justice. It calls for a paradigm shift towards sustainable, equitable food security approaches that recognise the interconnection of environmental, social, and political factors shaping global food systems. As a review, the methodology involved systematic synthesis of existing literature, using secondary data from peer-reviewed journals, policy briefs, and institutional reports. This enabled a thorough evaluation of current knowledge and gaps, with emphasis on gendered vulnerabilities and socio-economic disparities
Comprehensive SERVQUAL Assessment: Evaluating The Role Of Property Managers In Challenging The Environmental Kuznets Curve Within The Nigerian Real Estate Sector
No full textThe Environmental Kuznets Curve (EKC) contends that rising economic prosperity mitigates environmental degradation practices and orchestrates a greener economy. Despite decades of research, scholars remain divided on whether EKC adequately explains sustainability transitions in emerging economies. More pertinently, extant research is yet to test this hypothesis from a housing perspective considering its over 40% contribution to climate change. The paper interrogates these unresolved tensions by examining how environmentally aware property managers’ proactive capital allocation for green innovations contests the linear assumptions of the EKC. A structured SERVQUAL (service quality) survey was used to measure the reliability, assurance, tangibility, empathetic and responsiveness of sustainability transition by property managers. A purposive and stratified sample of 384 residents of high-end properties in Awka and Enugu was used to capture measurable sustainable housing service quality dimensions. Confirmatory Factor Analysis validated the model, while data analysis employed Structural Equation Modelling. Results show that tenants perceived low reliability in green infrastructure maintenance, limited confidence in managers’ expertise, and weak tangible adoption of energy-efficient systems. While income predicted perceived energy efficiency (β=0.55, p=0.000), SERVQUAL dimensions like tangibility (β=0.47) and reliability (β=0.32) showed limited moderating effects, exposing the EKC’s neglect of human agency. It was concluded that firm growth alone cannot drive sustainability without human agency. Theoretically, this advances environmental economics by linking service quality to ecological outcomes. Practically, it urges property managers to prioritize staff training and proactive green investments. Policy implications advocate for tax incentives and regulatory frameworks to incentivize sustainable practices in emerging economies
Assessing Thermal Performance In Two Classroom Building Types In Warm Humid Climate Imo State, Nigeria
Get PDFAchieving energy efficiency in educational buildings in countries located in the tropical regions is a big challenge because of very high temperatures and humidity. The problem is further complicated by designs that encourage the use of mechanical ventilating systems to provide thermal comfort. This paper presents the report of fieldwork carried out in primary schools in Imo State, Nigeria. It involved two naturally ventilated classroom building types categorized as short wall and enclosed wall classrooms. The aim was to determine and compare their thermal performance so as to provide information for use in design of sustainable school buildings in warm and humid environments like Nigeria. The data (environmental parameters and physical measurements) of these classrooms were collected during the rainy season and dry season. Results of the correlation analysis of the retrieved data showed that the two classroom types were in thermal compliance with the requirements of ASHRAE Standard 55. However, the relationship between the outdoor temperature and the indoor temperature in the short wall classroom-type was stronger (r2= .856), than the relationship found in the enclosed wall classroom-type (r2= .722). Furthermore, the prevailing daily mean indoor temperatures were higher in the enclosed wall classroom type. The difference in thermal performance in these two building-types is likely as a result of the difference in their building envelopes. It was concluded that the short wall classroom-type has a greater potential to contribute to reduced energy use in buildings. It was recommended that the short wall concept in the design of classroom blocks be adopted in the warm and humid climate, in Nigeria
Geospatial Distribution Of Waste Dumpsites And Socioeconomic Factors Influencing Waste Management Practices In Abeokuta South, Nigeria.
Get PDFRapid urbanisation has continually led to waste increase, placing a demand on dynamic waste management for effectiveness. This research focuses on the examination of the potential geospatial distribution of waste dumpsites and the socioeconomic impacts on managing waste in Abeokuta South, Nigeria. Fourteen (14) dumpsites were observed and mapped using geospatial techniques, with buffer zones of 100m, 500m, and 1km indicators monitoring significant residents vulnerable to the hazards relating to dumpsite. Households falling within the exposure buffer zone are then visualize. Additionally, structured questionnaires were administered to residents within these distances to evaluate the influence of socioeconomic factors—particularly income and education levels—on waste disposal methods, including open burning, open dumping, incineration, and waste collection. Results revealed that many households in Abeokuta South reside within 100m proximity to a dumpsite, a proximity linked to increased respiratory health risks. Furthermore, the study shows that lower-income and less-educated households were more likely to engage in open dumping and burning. Among these respondents, 68% and 46% who practiced open dumping and open burning, respectively, were low-income earners. However, keeping waste for collection was the most widely practiced disposal method across all income groups. 44% of low-income, 50% of middle-income, and 6% of high-income households adopted this practice. These findings reveal that while household income levels significantly influence waste management behaviors, the strategic placement of waste bins can help mitigate improper disposal practices across different income groups

Improving The Design Of Pediatric Rehabilitation Centre Using Environmentally Friendly Ideas: Case Study Of Some Selected Hospitals In South-East Nigeria
Get PDFPediatric rehabilitation centres play a vital role in the long-term recovery and developmental support of children with physical, neurological, or musculoskeletal conditions. Yet in many Nigerian hospitals, the architectural design of these centres neglects children’s environmental and emotional needs, which are essential for healing. This study examines how environmentally responsive design can improve pediatric rehabilitation centres in South-East Nigeria, focusing on two case hospitals: Federal Medical Centre, Owerri, and Amanda Hospital, Imo State. A mixed-methods approach combined site observations and semi-structured interviews with healthcare staff, caregivers, and administrators, alongside secondary data from journals and design manuals. Key dimensions assessed include spatial organisation, natural ventilation, daylighting, sensory qualities, landscape integration, and material choice. Findings reveal limited child-centred features, weak connection to nature, and minimal adoption of eco-friendly design strategies. Environmental comfort, emotional well-being, and functional efficiency emerged as critical gaps affecting therapeutic experience and outcomes. The study proposes context-sensitive design principles for Nigerian pediatric rehabilitation, emphasising biophilic elements, adaptive spatial layouts, and passive environmental control. The research contributes to healthcare architecture and sustainable design discourse and offers a practical framework to guide architects, policymakers, and health planners in transforming paediatric rehabilitation facilities in resource-constrained setting
Comparison Of Different Density Materials In Lightweight Concrete
Get PDFConcrete is a highly prevalent construction material in contemporary society. The quest to reduce the weight of this material has been the focus of research that has posed a challenge to both scientists and engineers. The primary difficulty in producing a lightweight concrete lies in reducing its density while preserving its strength and without negatively impacting its cost. Adding light aggregates to the mix design is a frequently used method to reduce the density of concrete. According to BS EN 206-1, lightweight concretes are characterized by an oven dry density ranging from 800kg/m3 to 2000kg/m3. This is achieved by substituting dense natural aggregates with lightweight aggregates, either completely or partially. The materials used in this study are available locally, these includes Cement, River sand, Granite, Coconut shells (CS), Sawdust (SD), Expanded polystyrene (EPS), Master Rheobuild 858, and potable water. The mixture was prepared using a ratio of 1part cement, 1.6 parts sand, and 3.2 parts aggregate, with a water-cement ratio of 0.5. There are three different mixtures which are the conventional concrete, sawdust concrete and polystyrene concrete. The conventional aggregates were replaced with SD, CS and EPS in same ratio of 0%, 10%, 20% and 30%. Master Rheobuild 858 Plasticiser 858 was then mixed with half of the water required. The concrete\u27s performance was evaluated based on its compressive strength and hardened density. The sample underwent testing at intervals of 7, 14, and 28 days. The compressive strength of the control sample (C0) at 28 days was 34.8 N/mm2, which successfully met the desired goal strength. Additionally, the density of the sample was measured to be 2447 kg/m3. S10, S20, and S30 exhibit compressive strengths and densities of 28 N/mm2 and 2198 kg/m3, 24 N/mm2 and 2081 kg/m3, and 18.4 N/mm2 and 1980 kg/m3, respectively, after 28 days. E10, E20, and E30 have compressive strengths and densities of 25 N/mm2 and 1884 kg/m3, 18 N/mm2 and 1752 kg/m3, and 12N/mm2 and 1653 kg/m3, respectively. The study determined that there is a reduction in both compressive strength and density. Nevertheless, given the circumstances, as the replacement material increased, both the strength and density also reduced. Lightweight concrete was achieved with 10% of EPS at 1884 kg/m3. This resulted in strength of 25 N/mm2, making it appropriate for M25 concrete. While it was achieved with 30% of SD and CS which has a density of 1980 kg/m3 and strength of 18.4 N/mm2. Hydrophobic compounds can be included into sawdust to mitigate its high water absorption rate
