The study presented an approach to accomplish the nearly zero-energy school building through the assessment of energy and economic performance of the design solutions with renewable energy systems. For energy use in the school building, the energy was mainly consumed by artificial lighting through the analysis of two years’ energy consumption. Avai...

In 2021, the South Korean government highlighted the Green Remodeling Project for Public Buildings as a crucial initiative for reducing building emissions and tackling post-COVID challenges. Aimed at enhancing energy efficiency and living conditions in public buildings, especially those used by children and the elderly, this project represents a no...

Poor outdoor air quality increases air pollutants indoors. Indoor and outdoor air pollutants adversely affect human health, especially in children, who are particularly vulnerable. In this study, indoor and outdoor BC (Black Carbon) and PM 2.5 were measured in an elementary school classroom located in an urban city in South Korea. Indoor and outdoo...

Indoor air quality can be influenced by various indoor activities. The indoor air pollutants generated by cooking activities can cause severe risks to occupants’ health in residential buildings. The present study conducted field experiments to measure indoor pollutants associated with cooking in 29 residential buildings. Due to an open plan in Kore...

Building energy consumption accounts for 30% of the total global energy consumption and is increasing every year. Improvement in the heat transfer performance of the building envelope to reduce energy consumption is a current research hotspot. In the present study, we investigated the performance of the slim double-skin window (SDSW) via empirical...

Recently, many researchers have become interested in occupant information and occupant-centric control (OCC) strategies, aiming for efficient building operation. Combining a camera with deep learning (hereafter referred to as deep vision-based occupancy counting) is a very effective method for occupancy counting, but there are not many studies eval...

The metabolic rate (MET) and clothing insulation (CLO), which are personal characteristics, are generally difficult to estimate automatically. In recent years, a combination of deep learning and computer vision (hereafter referred to as “deep vision”) has enabled real-time estimation of these characteristics. Although many studies have been conduct...

‘Occupant behavior’ is the primary mechanism determining indoor particulate concentrations. Various indoor human activities generate particulate matter. Human-building interactions, such as window opening behavior, change the number of outdoor particulate matter introduces to the building. ‘Daycare center’ where young children spend considerable ti...

Recently, several researchers have attempted to detect occupancy information and use it to reduce building energy. Although occupancy counting using a camera and deep learning is a very effective method that has recently emerged, there are few cases in which the experimental performance and utilization have been comprehensively evaluated. The purpo...

Vision-based (camera-based) systems, which can effectively sense occupant information, have garnered attention as a core technology in the Fourth Industrial Revolution. A detailed understanding of vision-based sensing systems is required to detect occupant information based on vision and use it for occupant-centric control. Therefore, in this study...

The rising indoor air pollution from particles is a cause for concern especially in houses where children and the elderly reside. In South Korea, assessment of exposure to particle number (PN) in residential apartments, which account for 76% of all houses, is limited. In our study, the indoor and outdoor PN (sizes 0.3–10.0 µm) concentrations were m...

Cooking is a major contributor to indoor particulate matter (PM) concentrations. Studies suggest that cooking-generated PM rapidly disperses even when a range hood is in operation, suggesting that range hoods fail to perform sufficiently when used in isolation. However, the performance of range hoods can be improved by a supply of make-up air equiv...

Due to the recent industrial development and COVID-19 pandemic, people are spending more time indoors. Therefore, indoor air quality is becoming more important for the health of occupants. Indoor fine particles are increased by outdoor air pollution and indoor occupant activities. In particular, smoking, cooking, cleaning, and ventilation are occup...

Indoor cooking is the main cause of particulate matter (PM) within residential houses along with smoking. Even with the range hood turned on, cooking-generated PM can spread quickly into the living room due to the heat generated by the cookstove. In order to improve the PM spread prevention performance of the range hood, a supply of make-up air is...

Efficient natural ventilation is an important approach to maintaining indoor air quality. However, owing to the increasing concentration of outdoor particulate matter (PM), natural ventilation without filtration results in the introduction of outdoor particles in buildings, thus increasing indoor exposure to PM. Indoor PM concentration is determine...

This study measured five apartments in the Daejeon. There is higher fluctuation for ambient air particle conditions. The average PN (particle number) concentrations was 5.2x10 ⁸ /m ³ . There are differences between five sites because of fluctuation for ambient air conditions. Particle concentration has different each occupant schedule. I/O ratios w...

The office building consumes cooling energy in the summer season. Building envelope such as different windows affects the indoor heat gain. Operation of the cavity in double skin façade (DSF) is widely used passive design and can reduce the cooling load. Many cases have applied a building envelope. However, increase the initial investments affect t...

A slim double-skin window (SDSW), which is a window that is naturally ventilated through a thin cavity of 20 mm, has recently been developed. This study aims to analyze the cooling energy performance of SDSW through field measurement and to numerically investigate its thermal characteristics and the influence of outer single glazing on it. The resu...

The fine particles (PM2.5, PM10) have worsened indoor air quality and have caused an adverse effect on health. While range hoods have been typically used to exhaust cooking-generated fine particles in residential buildings, it is difficult to remove the fine particles effectively. The present study analyzed the effect of cooking on indoor air quali...

One of the most important problems of cooking-generated particulate matter (PM) is that it rapidly disperses when the range hood is in operation during cooking. To improve the performance of the range hood and prevent the dispersion of PM, a supply of make-up air equivalent to the airflow rate of the range hood should be provided. In this regard, w...

The purpose of this study was to measure the concentration of cooking-generated particles and to assess the health risk of the occupants. Numerous particulates are released from the kitchen when people are cooking, and diffused to other spaces in house, which would adverse the health of occupants. Sufficient ventilation is needed to decrease the PM...

Purpose: Residential cooking(gas or electricity) emits many air pollutants. For Removal of these contaminants, range hood is play an important role in the cooking activities. However, deterioration about performance of range hood can be occur in used range hood which is not verified on performance by testing balancing and adjusting in apartment. So...
