Daylighting design and user satisfaction in indoor sports facilities: an empirical study Taiwo Ezekiel Adebakin, Kazeem Olayinka Alade, Oluwadamilola Ajoke Alabi, Adewale Segun Alabi, Idowu Hazeez Adebakin Facilities, 2025 Purpose This study aims to assess user satisfaction with daylighting design, features and arrangements in selected indoor sports facilities across Southwest, Nigeria. It identifies key challenges and their impact on user experience, performance and energy efficiency. Design/methodology/approach A quantitative deductive approach was used, using structured questionnaire administered to 228 users (athletes, coaches, spectators and managers) across six indoor sports halls in Lagos, Oyo and Ondo States. Data were analysed using descriptive statistics, Kruskal-Wallis H tests and ordinal analysis (ORDANOVA) to evaluate perceptions, challenges and satisfaction levels. Findings Users reported significant dissatisfaction with daylighting adequacy (weighted mean = 2.29), glare control (2.19) and visual comfort (2.23). Key challenges included insufficient natural light (mean = 3.29), excessive glare (3.39), poor maintenance (3.22) and weather disruptions (3.44). Regression confirmed glare control (ß = 0.48) and natural light availability (ß = 0.31) as primary drivers of dissatisfaction. Daylighting had minimal perceived impact on athletic performance (2.34) or energy savings (2.20). Research limitations/implications The study is geographically limited to Southwest Nigeria and relies on self-reported data. Future research should incorporate physical measurements of illuminance and climate-based simulations. Originality/value This study provides an empirical evaluation of daylighting dissatisfaction in West African indoor sports facilities, addressing a critical gap in tropical climate contexts. It establishes a climate-responsive evaluation framework adaptable to high-irradiance, low-resource regions – directly supporting Sustainable Development Goals 3 (good health and well-being), 7 (affordable and clean energy) and 11 (sustainable cities and communities) and offers evidence-based retrofit strategies for designers and policymakers.

PROPERTIES OF CONCRETE MADE WITH RECYCLED COARSE AGGREGATES FROM OLD CONCRETE CUBES I. H. Adebakin, J. T. Adu, O. M. Ofuyatan Proceedings of International Structural Engineering and Construction, 2015 Sustainability in the construction industry is a global concern, and one way of handling this is the idea of recycling old concrete rubbles in the production of fresh concrete. Recycled aggregate concrete is normally classified as light weight concrete and recommended for use in production of low-grade non-structural elements. This study examined the properties of crushed old concrete cubes as replacement for natural aggregate. Five specimens 150x150mm concrete cubes with varying percentages of coarse recycled aggregate of 0 %( control), 25, 50, 75 and 100% were prepared. All the mixes were proportioned using the absolute volume method with a targeted compressive strength of 30N/mm2 and varying w/c ratio. The result shows that with up to 75% replacement of natural aggregate with recycled aggregate, the 28 days compressive strength of concrete is in close proximity with that of normal concrete. While the strength of exclusive recycled aggregate concrete is about 15% lesser than that of exclusive natural aggregate. The result of this research confirms that crushed old concrete cubes can be safely used in the production of high grade concrete.

Groundwater assessment in a city suburb Joy T. Adu, Idowu H. Adebakin, Olaleye Abiona Isec 2015 8th International Structural Engineering and Construction Conference Implementing Innovative Ideas in Structural Engineering and Project Management, 2015 Owode, a sprawling water catchment area better known for its commercial activities in metal and iron casting and fabrication, is located off the Lagos Lagoon and the Ajuwon River, in Lagos State. The extensive iron and steel work along with seasonal flooding of the area and the habits of the people in this area is considered a threat to its groundwater integrity. Samples designated SW1, SW2, and SW3 for stream water WW1, WW2, and WW3 for well water and BH1, BH2, and BH3 for samples collected from boreholes were collected and analyzed to determine the presence of certain physicochemical elements and heavy metals. Including pH, EC, TDS, DO, SO42-, Cl, NO3-, and PO43-. Heavy metals analyzed include Fe, Pb, Zn, Cu, Cr, Cd, and Mn. The findings showed that while a number of parameters when compared with the WHO and NADWQ stipulated maximum acceptable concentration fell within acceptable limits, others especially the heavy metals had trace elevations above the maximum acceptable levels which if not checked could have serious future groundwater contamination implications.
