Attic ventilation and radiant heat barriers in naturally ventilated galvanized metal-Roofed buildings
The study's uniqueness stems from its goal of determining the efficacy of natural attic vents and radiation heat barriers on galvanized metal roof buildings in lowering attic and indoor air temperatures for thermal comfort in a humid tropical climate, a topic that has received little attention in previous research. This was accomplished by utilizing three separate experimental situations using two tiny models of single-sloped zinc-roofed houses, each with varied attic ventilation openings and radiant heat barrier applications. The thermal conditions of the attic and occupant rooms in the ventilated test cell tended to be cooler than in the unventilated one in the first experiment, which compared a test cell with 20% ventilation apertures in the attic to another test cell without ventilation. The second experiment, which compared a test cell with 10% attic ventilation to another test cell (without attic ventilation) with radiant heat barrier application, found that the radiant heat barrier's effect on temperature reduction was generally better. The third experiment, which compared a test cell with 20% attic ventilation to a test cell without attic ventilation but with radiant heat barrier application, revealed that attic ventilation outperformed the radiant heat barrier in terms of temperature reduction.
