This study is to compare and analyze ‘the Korean energy saving design standard in building’ with ‘the passivehouse standard of PHI’ in Germany in using of energy efficient factors which have an effect on reducing energy demand in building. We used following architectural design method for energy efficiency : direction, south oriented window-wall ratio, insulation, glazing, frame, heat recovery, external blind, airtightness, thermal mass, ect.
We set a base model and analyzed annual energy demand, heating&cooling demand through energy-simulation according to each standard above by energy efficient elements. Consequently, ‘the passivehouse standard of PHI’ is more effective on reducing energy use than ‘the Korean energy saving design standard in building’. Also, this study found energy efficiency rate for heating demand by elements and it is as in the following : Window(37.92%) > Heat recovery(27.87%) > Insulation(25.23%) > Airtightness(5.49%) > Internal/External Insulation(4.42%) > Thermal mass(3.99%) > South oriented window-wall ratio(0.29%) > External blind(0%). And we found that the external blind(56.2%) takes a key role in reducing cooling demand. Through this study, we discovered energy reducing rate by energy efficiency factors in building and with this result, we are expecting to make energy efficiency design standard for the improvement of the high energy-use detached house.
