Temperature Distribution in Walls and Roofs

Publication: Journal of Architectural Engineering
Volume 1, Issue 3

Abstract

Temperatures in the walls and roofs of an experimental shed were measured. An “average” mathematical model was established for the determination of heat flow through wall and roof elements with different surface finishes. The input meteorological data and parameters used in calculation are discussed. The measured data were used to calibrate the model and check the assumptions involved. Based on the established model, heat flow through wall and roof elements and efficiency of different surface finishes are compared. The thermal inertia of a 150-mm-thick concrete wall is significant. Heat transmitted through a wall also depends greatly on the color of its surface. The insulation layers reduce heat flow into the interior and increase considerably the thermal inertia of a roof. The study focused on the summer period.
