본 연구는 국내 주거건물에 Electrochromic window를 적용한 경우를 대상으로, 여러 제어변수 및 변색 기준값별로 에너지 성능의 민감도를 분석하였다. 제어변수는 실내 일광조도, 실외 수직면 일사량, 실내온도로 설정하였으며, 철원(중부1), 서울(중부2), 부산(남부), 제주(제주)를 대상으로 기후조건이 다른 지역별로도 에너지 절감 효과를 비교, 분석하였다. 그 결과 에너지 절감 효과가 가장 큰 제어변수는 실내 일광조도로 나타났으며 지역별로는 철원>제주>서울>부산 순서로 나타났다. |

The purpose of this study was to analyze the energy saving performance of Electrochromic window (ECW) by various control variables
through sensitivity analysis. To this end, control variables were established as daylight illuminance, solar radiation and indoor air temperature,
and then energy performance of ECW applied to residential buildings were evaluated using building energy simualtion tool, EnergyPlus (ver.
9.2.0). In addition, regional trends of Cheorwon (Jungbu1), Seoul (Jungbu2), Busan (Nambu), and Jeju (Jeju), which have different climate
condition, were compared. As a result, among the all control variables, the best reduction rate in the sum of cooling and lighting energy
consumption was found to be daylight illuminance, which was the same in all regions. In addition, the energy saving effect was in the order
of Cheorwon (9.1% to 12.3%) > Jeju (7.1% to 9.5% ) > Seoul (6.1% to 8.7%) > Busan (5.8% to 8.2%). In the case of solar radiation, the
lower the interior illuminance, the better the effect, but the best setpoint for tinting were different by region, so it was judged that prior
consideration about solar radiation setpoint for tinting is needed when conducting related research in the future. In the case of indoor
temperature, the higher the interior illuminance, the greater the energy performance, but the energy consumption saving effect was not
significant. |
