EFFECTS OF THERMAL INSULATION LOCATED IN THE EARTH AROUND A SEMI-UNDERGROUND ROOM: COMPUTER ANALYSIS BY THE FINITE ELEMENT METHOD.

Author(s) : YOSHINO H.

Summary

IN ORDER TO OBTAIN FUNDAMENTAL INFORMATION ON THE THERMAL PERF ORMANCE OF A SEMI-UNDERGROUND ROOM, CALCULATIONS BASED ON THE TWO-DIMENSIONAL FINITE ELEMENT METHOD WERE DONE USING VARIOUS FORMS OF UNDERGROUND THERMAL INSULATION IN ROOM MODELS WHOSE SIZE AND BUILDING MATERIALS WERE SIMILAR TO THOSE OF A TEST ROOM UNDER STANDARD WEATHER CONDITIONS IN THE CITY OF SENDAI IN NORTHERN JAPAN. THE EFFECT OF THE FOLLOWING FACTORS ON ROOM TEMPERATURE FLUCTUATION AND/OR HEATING AND COOLING LOADS WAS COMPUTED: (1) HEIGHT OF THE ROOM ENVELOPE ABOVE THE GROUND SURFACE ; (2) FORMS OF THERMAL INSULATION IN THE EARTH AROUND SEMI-UNDERGROUND ROOMS ; (3) SOLAR RADIATION INCIDENT THROUGH WINDOWS AND USE OF INSULATED WEATHER SHUTTERS ; AND (4) AIR-CONDITIONING MODE.
