    Investigating the Adoption of Passive Cooling Strategies in Selected Office Buildings in Abuja, Nigeria
    (IOP Conf. Series: Earth and Environmental Science, 2025) Oluwatayo, Adedapo Adewunmi; Nduka, Miracle D.
    The study investigates the adoption of passive cooling strategies in office buildings in Abuja, Nigeria, with a focus on promoting sustainable design and enhancing energy efficiency. By evaluating the implementation patterns of various cooling techniques and identifying factors influencing their adoption, the research highlights the potential of passive strategies to reduce energy consumption and improve thermal comfort. Through a quantitative approach, the study surveyed three office buildings selected via convenience sampling from a population of over fifty, achieving a 90% response rate from 73 distributed questionnaires. Factor analysis revealed fifteen distinct dimensions of passive cooling strategies, accounting for 75.836% of total variance. Enhanced ventilation, thermal mass utilization, and space optimization emerged as primary factors. Findings show a preference for conventional methods, including operable windows (mean = 4.6515), traditional building materials (mean = 4.6212), and hard landscape features (mean = 4.4923), while advanced techniques like evaporative cooling showed limited adoption (mean = 1.5937). This research contributes to sustainable building practices, offering insights for architects, developers, and facility managers while emphasizing the importance of integrating advanced passive cooling solutions into building design.

    An Assessment of the Influence of Passive Cooling Strategies on Level of Thermal Comfort in Selected Office Buildings in Abuja, Nigeria
    (Journal of Environment Sciences (JOES) ISSN 1118-8936 (Print); 3043-6176 (Online), Vol. 23, No. 2,, 2024-12) Oluwatayo, Adedapo Adewunmi; NDUKA, Miracle D.
    Buildings contribute significantly to global energy consumption, with cooling needs forming a substantial part of this demand. Passive cooling techniques present an energy-efficient alternative, promoting occupant comfort while reducing energy costs. This study analyzed the influence of passive cooling strategies on thermal comfort within office buildings in Abuja, Nigeria. Specifically, it evaluated current practices, analyzed implementation patterns, and provided recommendations for improved adoption. A quantitative research approach was employed, involving data collection through questionnaires distributed to 73 participants across three office buildings, with a response rate of 90%. The data, analyzed using both descriptive and inferential statistical techniques, revealed that most respondents (69.7%) reported discomfort. Regression analysis identified 15 significant factors affecting thermal comfort, including operable windows, courtyards, and window-to-wall area ratios, which had positive effects, while factors such as external insulation and vertical air shafts negatively impacted comfort. These findings offer insights into designing more sustainable and energy-efficient office environments, ultimately enhancing occupant well-being and productivity.
