Increasing risks of energy security and greenhouse gas emission due to the growing urbanization trend have prompted need for urban demand prediction management, in which building consumption is main cause. This paper reviews recent advances state-of-the-art modeling stock consumption, including both top-down bottom-up approaches. The study compares summarizes strengths weaknesses each primary method. Specific focus has been paid stochastic engineering methods, hold sound quantitative theory...
Electric vehicle, which is one of the major components and research areas Smartgrid, has been considered as way reducing greenhouse gas. ISO/IEC 15118 standard defines data communication interface to charge electric vehicles. The used in between vehicles power charging infrastructure. In this paper, security vulnerabilities based technology are analyzed, countermeasures for them proposed.
Even though the measures to minimize stack effect in high-rise buildings were taken that include a revolving door on lobby floor, additional barriers passage of air lower part building, and air-tightness reinforcement for elevator doors, is still present during cold season Korea. However, it difficult fully apply under occupied condition buildings. In this study, as an advanced method condition, mechanical ventilation shaft space, which cools space with outdoor reduces temperature or...
Building energy savings and occupant thermal comfort are the main issues in building technology. As such, development of energy-efficient heating, ventilation, air-conditioning (HVAC) systems control strategies HVAC emerging as important topics industry. Variable refrigerant flow (VRF) have efficient performance, so use VRF buildings is increasing. However, most studies on focus improving mechanical efficiency, with few while satisfying occupants. The goal to estimate energy-saving potential...
Because most existing smart grid models are conceptual, it is difficult to analyze in detail communication relationship between each component, such as advanced metering infrastructure, demand response, and distributed energy resources domain. Thus, this paper, we identify more concrete services with security threats requirements. Finally, suggest a new architecture model that focuses on the aspect using component.
The stack effect is dominant in multifamily high-rise buildings (MFHRBs) winter because of the considerable height MFHRBs, which causes a difference infiltration amount between floors. This heating load floors MFHRB. However, there are no indicators to quantify differences previous studies. In this article, an indicator—the thermal draft coefficient (TDLC)—is proposed that can be used estimate and evaluate TDLC built on theoretical model leakage area airflow paths, considering entire...
Apoptosis of outer hair cell (OHC) can be identified through nuclear staining by specific changes. The change filamentous actin (F-actin) is also involved in early death process. study was designed to investigate OHC along the whole length organ Corti.BALB/c hybrid mice were used this study. noise group exposed white 120 dB SPL for 3 hr per day consecutive days. tone burst auditory brainstem response (ABR) test conducted and cochleas from each obtained immunostaining FITC phalloidin F-actin...
Domestic hot water heating of multifamily buildings accounts for a substantial portion the energy load existing buildings. This is made up both required to produce and needed maintain temperature heated within building’s distribution piping so that heat can be promptly delivered building occupants as needed. Properly designed pump heater (HPWH) systems have ability improve efficiency in control operations. Further, CO2 technology reflects shift away from traditional refrigerants toward with...
The inhalation of a water aerosol from humidifier containing disinfectants has led to serious lung injuries in Korea. To promote the safe use products, Korean government enacted regulations on chemicals various consumer products that could have adverse health effects. Given concern over potential risks associated with hazardous ingredients deodorizing 17 were analyzed and assessed according their risk 3 groups by application type 47 products. assessment study followed stepwise procedure...
