Computational fluid dynamics (CFD) simulations of thermal manikins can provide detailed information which it is impossible to obtain from experiments. In this review several issues from CFD studies of thermal manikins are discussed, such as geometric complexity of computational thermal manikins (CTMs), selection of turbulence models, grid generation and boundary conditions. Calculation of CTMs ...

This study aims to shed light on the correlation between spatial composition and indoor airflow as a passive design used in contemporary tube houses Ho Chi Minh City (HCMC), Vietnam. In this constraint housing typology due rapid urbanization, clarifies patterns of living room bedroom for their architectural environmental characteristics such placement, openness, area wind path. By revealing var...

Smartphone applications or electronic devices in the form of occupant voting systems (OVS) have demonstrated to be feasible for acquiring feedback from occupants support building operation manager identify indoor environmental quality (IEQ) problems and inappropriate control settings heating, ventilation air-conditioning (HVAC). The present paper aims contribute growing research on OVS as a too...

This paper presents results of an experimental procedure to observe the impact of building materials on perceived air quality. An untrained panel of 25 adult subjects perceived the quality of polluted air in smallscale chamber settings. The air pollution was generated by emissions from individual materials, by combinations of these materials and by mixtures of emissions from single materials. T...

The central air-conditioning system attract people’s attention because the thermal comfort can be improved by arranging air outlets properly. Moreover, various blow out conditions may adopted to improve indoor environment. In this research, simulation studies accuracy of CFD Momentum method under has been conducted. Firstly, airflow distribution each blowing condition was measured isothermal co...

BACKGROUND The complex hospital environment requires special attention to ensure healthful indoor air quality (IAQ) to protect patients and healthcare workers against hospital-acquired (nosocomial) infections and occupational diseases. The aim here is to recommend effective guidelines for the control and management of hospital IAQ. MATERIAL/METHODS The authors have done an extensive literatur...

The traditional architecture of Kerala, a state in India lying along its southwest coast, is known for its use of natural and passive methods for a comfortable indoor environment. Although there have been attempts to analyze the traditional architecture of Kerala, they were focused only on qualitative approach. An investigation was thus initiated by the authors to understand the passive environ...

Radiant floor heating has received increasing attention due to its diverse advantages, especially the energy saving as compared to the conventional dwelling heating system. This paper presents a numerical investigation of airflow and heat transfer in the slot-vented room with the radiant floor heating unit. Combination of fluid convection and thermal radiation has been implemented through the t...

Abstract Humidity of indoor air is an important factor influencing the air quality and energy consumption of buildings as well as durability of building components. Indoor humidity depends on several factors, such as moisture sources, air change, sorption in materials and possible condensation. Since all these phenomena are strongly dependent on each other, numerical predictions of indoor humid...
