Received 11th December 2024; Accepted 6th February 2025 ABSTRACT: This study investigates the impact of changing temperatures on building structures in Asaba and Okwe, Nigeria. Utilizing primary data from temperature readings and secondary meteorological records spanning 30 years, the study reveals a clear trend of rising temperatures in both areas, with Asaba experiencing consistently higher temperatures than Okwe, largely due to the urban heat island effect. The research highlights the vulnerability of building materials, particularly zinc roofs and walls, to temperature-induced stresses such as thermal expansion and contraction, leading to cracks and structural degradation. Statistical analysis, including regression and ANOVA tests, demonstrates a moderate positive relationship between temperature fluctuations and the extent of building damage. These results highlight how urgently better building techniques, environmentally friendly urban design, and climate-adaptive measures are needed. To ensure long-term resilience and sustainability, this study offers Asaba and Okwe's urban planners and policymakers some important insights on how to effectively adapt to the difficulties presented by urbanisation and climate change. Keywords: Building structure, Nigeria, Okwe, structure integrity, temperatures. INTRODUCTION Climate change research is a complex and contentious field due to system complexities and modelling uncertainties (Malla et al., 2022). Future changes to weather patterns include warmer and drier summers, milder and wetter winters, rising sea levels, and extreme events such as increased hot days (Met Office, 2021), more intense periods of rain, and greater frequency of storms. Buildings are systemic structures with many interacting systems and subsystems. In Nigeria, many structural failures have occurred in recent years, almost in all areas of the built environment owing to the vagaries of weather and climate (Ede, 2010; Akinyemi et al., 2016). Regular one-day non-stop rainfall held the entire Lagos State in Nigeria to a standstill due to failed drainages and flooded-potholed roads (Kalu, 2024). Of the 65 cases of building collapse around Lagos and its environs, 384 human casualties were reported, while the number of injured was numerous (Windapo and Rotimi, 2012; Aliyu, 2024). Climate factors, including temperature, wind speed, solar radiation, and daylight hours, significantly influence building energy performance in the Nigerian built environment (Bett and Thornton, 2015). Building performance and structures can be influenced in direct and indirect ways, and to make an effective estimation of the impact of climate on overall energy (Ahmadian et al., 2023), the selection of climate element collection should be based on the combined integrated impacts of the climatic elements (Radhi, 2008; Lutz et al., 2016). The lifecycle cost of a building is about 60 to 85 percent, with design and construction accounting for five to ten percent (Lewis et al., 2011; Sanodiya and Rathore, 2024). Nigerian buildings often lack climate adjustment,
