Impact of Color on Energy Efficiency in Interior Space Design

This study explores the impact of color on energy efficiency in interior design, focusing on three building types: a secondary school, a hospital, and a residential building. Through a questionnaire administered to occupants, the research found that lighter colors enhance natural light reflection, reducing reliance on artificial lighting. In residential settings, 75% of respondents reported improved lighting efficiency with light-colored walls. In hospitals, darker color schemes were preferred for their cozy atmosphere but led to higher energy consumption due to increased cooling demands. In educational environments, lighter colors contributed to thermal comfort, especially in spaces exposed to direct sunlight. User satisfaction was linked to both aesthetic appeal and energy performance, with many preferring lighter tones for a brighter, more open environment. The study concludes that strategic color selection is essential for energy-efficient designs and offers recommendations for prioritizing lighter colors, using darker tones selectively, and involving occupants in the design process. These findings highlight the importance of balancing aesthetics with energy efficiency for sustainable interior spaces.
