Buildings represent a major part of the world energy requirement. The simulation of combined heat, air and moisture (HAM) and pollutant transfer in this context is important to predict the indoor air quality (IAQ), along with the thermal comfort inside the buildings. Moreover, it is important to have appropriate levels of indoor humidity along with the room temperature as movement of water vapo...

This study investigated the ventilation efficiency and energy performance of three strategies—an all-air system (AAS), a radiant panel with displacement (DPS), decentralized (DVS). The research analyzed indoor air quality (IAQ) in high-rise building based on building’s height, handling unit (AHU) location, infiltration rate, outdoor pollution seasonal change, filter efficiency. results indicate...

To develop and evaluate housing strategies interventions for improving indoor air quality (IAQ) at a city or national scale, stock IAQ models are required. Without such models, reliable prediction of residential pollution concentrations exposures various spatial-temporal scales cannot be achieved. address the areas not covered by past review articles in performance modelling, this paper present...

Due to increasing health and environmental issues, indoor air quality (IAQ) has garnered much research attention with regard incorporating advanced clean technologies. Various physicochemical treatments have been used monitor, control, manage contaminants, such as monitoring devices (gas sensors internet of things-based systems), filtration (mechanical electrical), adsorption, UV disinfection, ...

In our practice, clients increasingly approach us with complaints related to asthma and allergy triggers. These need to be addressed separately from many of the other exposure-related risks we are used to dealing with on a daily basis. There is more to IAQ than monitoring radon, heavy metals, VOCs, biologic contaminants and molds. In the interest of your clients, you may want to include another...

The mitigation of indoor air pollution sources in printing facilities is crucial for ensuring healthy environments and protecting the health well-being employees. This study assessed severity different pollutant control strategies use 22 presses Zaria metropolis, Kaduna State. adopted a quantitative method. A checklist was used to characterize selected examine on 5-point Likert scale. instrumen...

Gaps in internal audit function (IAF), such as quality (IAQ), began to be pointed out by studies carried after Sarbanes-Oxley (SOX) Act publication. As a subject still under development the literature, this article seeks delineate research profile for IAQ period from 1999 2021. To end, bibliometric on was conducted, resulting identification of how area has progressed over last 22 years, encompa...

background: in the past few decades, indoor air pollution (iap) has become a primary concern to the point. it is increasingly believed to be of equal or greater importance to human health compared to ambient air. however, due to the lack of comprehensive indices for the integrated assessment of indoor air quality (iaq), we aimed to develop a novel, fuzzy-based indoor air quality index (fiaqi) t...

Window operation is among one of the most influential factors on indoor air quality (IAQ). In this paper, we focus modeling windows’ opening state in a real open-plan office with five windows. The IAQ was monitored over whole year along A k-Nearest Neighbor (k-NN) classification model implemented, based long time series both and outdoor environmental such as temperature relative humidity, CO2 c...
