ACTUAL MEASUREMENT ON HEAT FLOW THROUGH A SOLID GROUND FLOOR WITH AN INSULATED FOUNDATION AND EVALUATION ON VARIOUS INSULATION METHODS BY NUMERICAL ANALYSIS

Abstract

This study shows the actual measurement and simulation results of heat flow through a solid floor in contact with the ground and with a vertical layer of edge insulation. The rate of heat flow was estimated to be about 3-5 W/m² in summer, which was about twice as large as one by a wooden floor. The results also show that the improvement of insulation over the current is not always effective except the outside insulation of the foundation. The use of an overall layer of insulation under the concrete must be studied by the thermal property of the ground under the floor.
