This study is to predict energy independence in Green Home by energy performance evaluation and present fundamental data
of heating and cooling system by optimal design and energy analysis about Ground Heat Source Heat Pump(GSHP) system as a
alternative. Green Home analysis was carried out with consideration over energy of heating, cooling, domestic hot water, lighting
and equipment while heating-centered energy analysis was avoided. The Green Home will be built in Chung-nam and was
planned at 167㎡ and 2nd floor. The structure was reinforced concrete and such key technologies as super-insulation,
super-window, economizer, shading system and GSHP system were applied. Also base model which meet domestic construction
law was selected for key technology analysis. As s result of simulation, heating, cooling, hot water, cooking and lighting energy
consumption of base model were 101kWh/㎡, 39kWh/㎡, 17.36kWh/㎡, 16.6kWh/㎡, 24.76kWh/㎡ respectively. In case super
insulation of 250mm is applied at building surface, heating and cooling energy can be reduced by 28.6% and 1.5% respectively.
However, if economizer is installed, cooling energy is increased by 28.6% while heating energy is decreased by 35.9%. In case
super-windows are installed, heating energy is decreased by 15.1% but cooling energy is increased by 16.3%. If three of key
technologies and shading system which can prevent indoor temperature rise by insolation are applied, 52.9% total energy
consumption (heating 20.2kWh/㎡, cooling 27.9kWh/㎡, cooking 16.6kWh/㎡, hot water 17.36kWh/㎡, lighting and equipment
24.76kWh/㎡)can be reduced. If GSHP system is installed, heating and cooling energy can be decreased by 90%.
