    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.
