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.

University dormitory is a kind of representative building in which central heating is supplied. The rooms are in simple types and the students’ activity schedule is quite steady, which makes dormitory room to be an appropriate place for field survey. This

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

Confined environments are indoor spaces which are not ventilated or few ventilated due to specific use (shelters, submarines …). In such environments, homogeneous and heterogeneous chemistry are expected to play a key role in indoor air quality (IAQ). The

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.
