INVESTIGATING THE EFFECT OF SHEDDING DEVICES ON INDOOR THERMAL COMFORT OF RESIDENTIAL BUILDINGS IN EMEKUKU, NIGERIA
Abstract
Indoor thermal comfort is a critical factor in residential building design, especially in
tropical climates like Emekuku, Imo State, Nigeria. This study investigates the effects of
shading devices on indoor thermal comfort in residential buildings, focusing on their role
in mitigating heat gain and improving occupant comfort. The research adopts a mixed
methods approach, combining field measurements, simulations, and occupant surveys to
evaluate temperature, humidity, and thermal perceptions across different shading
strategies. Key shading devices analyzed include overhangs, louvers, and vegetation
based solutions. Findings indicate that properly designed shading devices significantly
reduce indoor temperatures by limiting solar radiation penetration, enhancing thermal
comfort, and reducing reliance on mechanical cooling systems. The study emphasizes the
importance of incorporating passive shading techniques in residential building design to
improve energy efficiency and occupant well-being. Recommendations are provided to
guide architects, builders, and policymakers in adopting effective shading strategies for
sustainable residential development in Emekuku and similar tropical regions.
