PERCEPTION OF BUILDING OCCUPANTS AND PROFESSIONALS TOWARDS THE INFLUENCE OF THERMAL TRANSMISSION AND MICROCLIMATIC ON RESIDENTIAL BUILDINGS IN BOSSO ESTATE, MINNA, NIGERIA

Abstract

This study examined the perception of thermal transmission and microclimatic influences in residential buildings in Bosso Estate, Minna, Nigeria. The study assessed occupants’ perceptions of thermal transmission, evaluated the impact of microclimatic factors on indoor temperature, and identified building materials and architectural features affecting thermal comfort. A descriptive survey design was employed, encompassing 120 respondents, including 100 building occupants and 20 building professionals. Data were collected using a 51-item structured questionnaire and analyzed with mean, standard deviation, and independent t-tests at a 0.05 significance level. Findings indicate that thermal transmission is perceived through roofs, ceilings, windows, walls, and ventilation systems (M = 2.83–3.11), while microclimatic factors such as solar radiation, airflow patterns, and internal heat loads significantly influence indoor temperature (M = 2.77–3.01). Building materials and architectural features including insulation, glazing, shading devices, and ceiling height also affect thermal comfort (M = 2.71–3.02). No significant differences were observed between professionals and occupants (p > 0.05). The study recommends integrating climate-responsive design and thermally efficient materials to optimize residential indoor environmental quality.
