The ceiling radiation heating system having solar power as a heat source and joint system of air conditioning and floor heating were installed in a highly airtight and adiabatic house. In this report, data obtained from the long-term measurement were analyzed, and comfortableness and energy-saving depending on operating methods (use of air conditioning alone, joint use of air conditioning, panels and floor heating, and use of panels alone) under the same outside air conditions were studied with such figures as COP, PMV and SET. In addition, it was examined what impact ceiling radiation panels had on indoor thermal environments before and after panels were in operation. The reliance on electric and natural energy was also investigated in order to find how effective the use of solar power was. It has been found that the use of panles alone made the distribution of vertical temperature more uniform than the joint use of panels and air conditioning and that the intermittent use of both panles and air conditioning saved energy and kept indoor environments comfortable. The outcome that the reliance on natural energy stood at between 20 and 40 percent has shown that the use of solar power was effective. It has been discovered that the ceiling radiation system using solar power was more effective than the conventional heating system in terms of energy-saving and comfortableness.
