The present paper is a review on methods and technologies for air cleaning from micro organisms andviruses, which are applicable with the present HVAC practices. The advantages and the drawbacks ofair dilution, filtration (HEPA, ULPA), ultraviolet germicidal irradiation (UVGI), photocatalytic oxidation(PCO), plasmacluster ions and other technologies for air disinfection and purification is criticallyanalyzed with respect to the used today air distribution principles.

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.

As presented by the Energy Green Paper “A European Strategy for a sustainable, competitive and Secure Energy” (1), Europe has entered a new energy era. Global demand is increasing within a framework of high and unstable prices. Emissions of greenhouse gas

Experiments using human subjects have been conducted to investigate the physiological andpsychological responses to two different heating methods, i.e. floor heating and air conditioner, in ahighly insulated house. This paper describes a study on the effects of the heating methods on skintemperature changes by investigating changes in skin temperature caused by thermal conditions,sexual differences in skin temperature change, the correlation between declared scores and drops inperipheral skin temperature using the experimental results.

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.

Methods are needed for the evaluation of the energy performance of complete buildings and parts ofbuildings or building installations. In order to arrive at energy efficient buildings, materials and productsthat effectively contribute to the thermal performance of the building and its installations must be used.For that standards dealing with the design and evaluation of materials, components and systems playan important role.

To achieve the Kyoto Protocol target, additional measures for reducing GHGs from the building sectoris a strong requirement in Japan. While this situation, building occupants are eager to secure asufficient energy supply in terms of developing business and living continuity plan (BLCP).

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.
