Impact of Room Colors and Construction Materials on Temperature Distribution in Tropical Climate: An Experimental Study in Nonthaburi, Thailand

This experimental research investigates the thermal performance of different room colors and construction materials under Thailand's tropical climate conditions. The study was conducted over a six-month period in Nonthaburi, Thailand, examining temperature variations across multiple room configurations. Using precision monitoring equipment, we analyzed how traditional Thai building materials and various wall colors affect indoor temperature distribution. The research encompassed both modern and traditional Thai construction materials, including concrete, brick, traditional teak wood, and bamboo, combined with different wall colors (white, cream, terra cotta, and dark blue). Results demonstrated that rooms with traditional materials like teak wood maintained lower average temperatures (by 3.2°C) compared to modern concrete structures, while light-colored walls showed up to 4.1°C temperature difference compared to darker colors during peak sunshine hours.
