초록

The current energy consumption of buildings occupies 23.5% of the total energy consumption in Korea, a high ratio, of which about 22% is consumed through lighting energy. For that reason, various experiments and research have been undertaken to reduce the energy consumption needs of indoor artificial lighting. This study suggests a light-shelf system applied with user recognized technology based on considerations of the light-shelf system and user recognized technology, and verified the possibility of introducing it to residences, and its effectiveness by comparing the results of energy reduction performance evaluations for the proposed light-shelf system with the user recognized technology and that with user unrecognized technology.
The light-shelf system applying user recognized technology is a system that allows the occupant to set the luminance value of the room so that the light-shelf system and lighting can be interlocked and provide the luminance value requested by the occupant. In order to verify the energy reduction effects of the light-shelf system with the user recognized technology applied, this study has calculated the power consumption of lighting energy for a user unrecognized fixed light-shelf system, a user recognized fixed light-shelf system and a user recognized variable light-shelf system. From the results, when comparing the user unrecognized fixed light-shelf system and the user recognized fixed light-shelf system, Case A did not generate a reduction in energy consumption, and Case B saw a 4.4% reduction of lighting energy consumption levels. Case C generated a 13.3% reduction of lighting energy consumption. When comparing the user recognized fixed light-shelf system and the user recognized variable light-shelf system, power consumption was equivalent in Case A of one occupant and A, B and A, Case C for 2 occupants, while a 13.3% energy reduction was achieved for Case B of 1 occupant and B, Case C of 2 occupants. Case C of 1 occupant also achieved a 15.2% lighting energy consumption reduction. The user recognized variable light-shelf system showed the largest reduction of lighting energy power consumption, followed by the user recognized fixed light-shelf system and the user unrecognized light-shelf system in order of the reduction of lighting energy power consumption from user recognition.
