The design and management of the indoor environments buildings should foster ‘‘health wellbeing’’. Buildings affect health occupants in many ways, for example, through building related illnesses, sick syndrome allergy, environmental problems. principal causes majority cases are to microbial effects emissions volatile organic compounds (VOCs) formaldehyde from materials or products used buildings. Lighting inadequate ventilation, particularly airtight also important factors. New refurbished...

This paper provides a review of the building environmental schemes for rating indoor air quality which could have an important impact on health and wellbeing occupants in sustainable homes buildings. The majority assessment introduced different countries world are based BREEAM LEED model. has major emphasis energy efficiency whereas ‘‘Indoor Environmental Quality’’ ‘‘Health Wellbeing’’ most central issues LEED. criteria included BREEAM, HK BEAM systems (IAQ) illustrated. There should be IAQ...

The outbreak of pneumonia caused by 2019 Novel Coronavirus arises significant concern for virus transmission and control. control the indoor environment or public-enclosed is crucial to reduce risk infection. Heating, ventilation, air-conditioning (HVAC) systems are used create a healthy, thermal-comfort environments. Thus, rational use HVAC great importance environmental infection improve human wellbeing in pandemic. In order satisfy requirement better healthy more thermal comfort...

This paper considers the requirements for investigation of sick buildings including some guidelines assessment exposure risks with a particular focus on dampness, proliferation moulds, and dispersion fungal spores in indoor environments. Building pathology, indoors air quality management bio-deterioration, health problems are complex issues requiring multi-disciplinary investigations environmental monitoring. Lack maintenance, chronic neglect, building defects leading to water ingress,...

The purpose of this paper is to provide a review developments in Korea relation its energy consumption and sustainable development policies progress achieving targets as given by the Building Energy Codes. insulation passive building technologies are also reviewed for house standards 2017 zero-energy or near buildings (nZEB) 2025 Korea, identify strategies further reduce usage primary achieve efficiency targets. A defining feature ability significantly environmental impacts embodied...

This paper discusses the emission of formaldehyde and VOCs from wood-based panel products effect on indoor air quality (IAQ). The concentration monitored in four energy efficient test houses over a 7-year period has been included to illustrate long-term emissions E1 panels used dwellings. Formaldehyde floorboard obtained investigation sick buildings are for comparison. Also discussed was impact fitting “low emitting” wardrobe an energy-efficient house apartment home. exposure risk individual...

Supply of hot water, including space heating and domestic water (DHW), is very important for the creation indoor environment. Hot not only most source in winter, but also widely used bathing, washing, swimming so on. It exaggerated to say that human being cannot live without water. The building energy consumption contributes 30– 40% total developed countries, about 15–25% developing countries. 1 breakdown by end uses countries summarized Table 1. 1,2 In residential sector, 20–50% DHW, 10–20%...

Hourly particulate matter mass concentrations and meteorological parameters, recorded by the China National Environmental Monitoring Center (CNEMC) Observatory, between June 2013 March 2016 in Beijing, Xi'an, Shanghai Guangzhou were examined to explore correlations. Characteristics of a rapid (abrupt) rise PM2.5 concentration during early stage serious urban PM pollution event compared with events gradual (accumulative) concentration. The accumulative air is characterized prolonged slow...

A new ventilated Trombe wall (VTW) constituted with double Phase Change Material (PCM) wallboards (PCMs-VTW) has been developed. The year-round thermal performance of the system was evaluated via an experimentally validated model. impact transition temperature PCMs and air change rate on cooling heating load were determined. Also, total energy electric consumption fan evaluated. PCMs-VTW can contribute to a reduction in (14.8%) (12.7%) when fusion temperatures exterior interior PCM 26°C...

Formation of haze is a phenomenon dependent on the relative atmospheric humidity and concentration aerosol particles. The physical chemical reactions particle surfaces would lead to variations in sizes. This paper focuses behaviour particles under influence humidity, which produces liquid bridging forces electrostatic interactions among By water absorption experiment, correlation between (RH) content was obtained. Through theoretical derivation, relationship ratio established for calculating...

Observation data show that natural wind has a characteristic of regular time-variation in speed and direction. However, the time-varying inflow conditions are usually simplified as constant profile simulations on airflow pollutant dispersion urban street canyons and/or building cluster. The study characteristics canopy layer (UCL) flow under should be further contribute to understanding energy transport processes atmospheric environment. In current work, typical studies air array reviewed....

Dynamic optimal airflow ventilation can have a great impact on the indoor air distribution and pollutant removal to improve quality while saving energy. An online monitoring control system has been developed evaluated using fast prediction models micro-control. environmental chamber (1.8 m 3 ) was used for evaluation monitor CO 2 dispersion under different change rates speed. Specifically, an artificial neural network model based low-dimensional linear introduced validated provide rapid of...

In this work, the thermo-sensitive materials N-isopropylacrylamide (NIPAM) and acrylic acid (AA) were crosslinked with carboxymethyl cellulose (CMC) (CMC/P (NIPAM-co-AA)) via a free radical polymerization method for removal of U(VI) from aqueous solution. The L16 (45) orthogonal experiments designed optimization synthesis condition. chemical structures crosslinking hydrogel confirmed by FTIR spectroscopy. microstructural analyses conducted though scanning electron microscopy (SEM) to show...

In recent years, the pollution of air environment has been increasing, which seriously endangered human health. The large amount coal burning and automobile exhaust emissions in winter have caused serious regional pollution, greatly increased prevalence respiratory disease people. purpose this study is to use Jilin Province as an example map out environmental status Northeastern China, provide suggestions for improvement atmospheric environment. Using annual data China's monitoring, was...
