In recent years, occupants conduct various behaviors in the appurtenant dressing room, so it isimportant to know the amount of modern moisture production in the appurtenant dressing room.Investigation data showed amount of moisture production caused by the behaviors in the dressingroom did not differ between males and females, and amount of moisture production caused by washingclothes and drying clothes did differ depending on the equipment.
Houses which use only electricity are becoming popular in Japan. Electromagnetic ranges (IH range)are used in those houses. The updraft above an IH range is slower than a gas range. The requiredventilation rate is different for a gas range and an IH range. In this study, measurements of updraftvelocity and temperature distribution above the IH ranges are conducted.
Recent studies suggest the reactions between ozone and indoor materials and contaminants caninfluence human health and perceived indoor air quality within a building. This analysis uses datafrom the U.S. EPA Building Assessment Survey and Evaluation (BASE) study to determine if there is anassociation between increasing outdoor ozone concentrations and increased reporting of BuildingRelated Symptoms (BRS) by occupants. Multiple logistic regression (MLR) models, which adjustedfor personal, workplace and environmental variables, revealed statistically significant (p
Methods of computational fluid dynamics (CFD) have been applied to predict the details of air,contaminant and thermal transport within isolated building zones, yet zone transport processes do notoccur in isolation they result from and interact with transport from the larger building system in whichthey are embedded. Consequently, there is a growing interest in combining CFD models of individualzones within multizone models of enclosing building systems to more faithfully model both the largerbuilding interactions and the intrazonal details.
Many homes in New Zealand are poorly constructed and maintained for the climate with inadequateheating resulting in winter temperatures that frequently fall below the World Health Organisationrecommended level of 18C. Approximately 30% of New Zealand homes are heated by unfluedportable gas heaters. To investigate the link between the indoor air environment and respiratory healtheffects in children, we studied 409 households that used unflued gas heaters or electric heating andhad an asthmatic child.
The requirements for good indoor air quality and energyefficiency have often been considered to conflict with each other, however, buildings with low energy consumption in Europe seem to have also a lower rate of building related health symptoms. This indicates the importance of proper design, installation and qualified, well trained operational personnel, who understands both the requirements for good indoor air quality and energy efficiency.
In order to show the efficiency of Phase Change Materials(PCM) in building walls we have used the software CODYMUR. The aim of the simulation is to evaluate the optimal thickness of the material and its behavior for different speeds of temperature evolutions in the room. The conclusion deals with the behavior of the wall due to the phase change phenomenon with a non linear thermophysical properties in comparison with a pure sensible storage layer.
The Clathrate Hydrate Slurry (CHS) of Tetra-n-Butyl-Ammonium Bromide (TBAB) comes into being under normal atmosphere when aqueous TBAB solution is cooled to 5-12 . It is a kind of high-density latent-heattransportation medium. CHS of TBAB has far higher cold-loading density than that water does, and can be transported easily through pipeline. So it can save the circulating pump power, and isvery promising to apply TBAB CHS into central air-conditioning or district coolingsystems as a new secondary refrigerant. In this paper, the pipe flow experiments of TBAB CHS are carried out.
Many schools today have a need for artificial cooling over the year but most of the classrooms do not have any cooling capacity installed. This fact results in high room temperatures as well as poor thermal comfort. However, new research shows that an increased air velocity during short periods can create an improved temperature tolerance in human beings. The high velocity pulses are short, a few minutes, so that the air movements should not be perceived as draft. This means that, within certain limits, it is possible to let the room temperature rise with maintained comfort.
This paper concentrates on the results of sustainability caused by Courtyard as a climatic element in Iranian traditional architecture of hot-arid regions. Traditional architecture of Iran is perceived sustainable for having sustainable features. It is able to response to environmental problems from a long period.
