Although interest in and the importance of green building certification have increased, it is difficult to determine how much less energy buildings actually consume after obtaining sustainability related certification, such as LEED USA, G-SEED Korea. Focusing on evaluation, we compared analyzed evaluation items G-SEED. In addition, from Korean public data portal site, this study investigated annual site consumption (electricity gas) per floor area non-residential that obtained The...
Purpose: Starting in 2020, the Ministry of Land, Infrastructure and Transport KOREA has implemented a green remodeling support project that provides government subsidies for construction old public buildings. In addition, signature was prepared to invest large amount cost among buildings subject remodeling. this study, we aim compare energy saving effects S Public Health Center North Chungcheong Province through analyze cost-effectiveness compared saved. Method: An evaluation conducted...
The main purpose of this research is to analyze and compare the energy performance two different novel air conditioning systems; one a dedicated outdoor system (DOAS) with parallel other heat-pump-integrated liquid-desiccant evaporative-cooling-assisted 100% (HPLD-IDECOAS). It was assumed that office buildings served by each were located in six cities representing four climatic regions China. hourly thermal loads meeting local building design codes selected city predicted TRNSYS 18 software...
The objectives of this study are to investigate input variables photovoltaic generation programs and compare their prediction actual system in the C city hall sewage treatment plant. We investigated amount generation, forecast solar radiation data, calculated relative errors. simulated plant located Chungju using existing programs, such as SAM, RETSCREEN, HOMER, PV SYST, Solar Pro. result follows : Through examining errors monthly predicted data showed big winter season?. Except season, no large
Currently, global warming is accelerating, and many countries are trying to reduce greenhouse emission by enforcing low energy building. And the thermal performance of windows one factors that greatly influence heating cooling consumption buildings. According development window system, improved. There simulations tests for evaluation techniques, but both time consuming costly. The purpose this study develop a convenient method predicting U ‐value at system design stage multiple linear...
The purpose of this study is to analyse the heat flux difference and examine applicability sensor along with various attachment methods. Using multiple sensors tapes, a KS F 2278 thermal test was performed in hot/cold chamber conditions standard panel specimen. measured values were stable. But smaller than result 2278. Thus, resistance tape on should be considered during site U-value measuring process. This also examined differences between design by attaching different same area using...
Countries around the world develop and use software based on monthly calculation method of DIN V 18599:2007 EN ISO13790 for building energy performance evaluations. The purpose this study is to propose a that can consider effect reducing cooling demand by hybrid ventilation outdoor air in method-based software. For simulation, some representative floor plans area types Korean residential buildings were established through literature research. A number dynamic simulations performed various...
Purpose: Air pollution is becoming serious around the world, and indoor air quality in buildings also deteriorating. For energy-saving ventilation good environment, this research proposed made a window type heat exchange system that can be installed easily an existing house, examined its performance. A plate element for ventilator was by 3D printer. Method: According to Korean Industrial Standard KS B 6879:2020 Test Method Heat Recovery Ventilator, tested four times real environment. Two...
Energy saving of buildings is a big issue because building energy occupies about 25% national energy. To reduce energy, many countries try to control by laws, such as regulations. This study has two objectives. The first evaluate efficiency rate specific using annual analysis software based on BIM tools. second objective usage adopting passive and active architectural strategies under the Korean rating regulation. A newly constructed public library was selected simulation base model, few...
