Determination of air permeability of buildings according to IS0 9972 orEN 13829 - Proposal for clarifications | 2008 | English
The Decision-making Process for Material and Ventilation Rate consideringIAQ and Cost in Apartment Buildings | 2008 | English
Indoor air concentration is mainly affected bythe emission rate of contaminants frommaterials and the ventilation rate. Therefore, theappropriate selection of materials andventilation rate is an important factor for indoorair quality.
To obtain thermal comfort in a moderateclimate, dwellings were traditionally providedwith a heating system, but few had coolingsystems.
An integrated building concept is a prerequisiteto come to an energy efficient building with agood and healthy IAQ indoor comfort.
A Study of the Ventilation Performance for Automobile Indoor AirPollution Reduction | 2008 | English
In this study, we evaluated the ventilationperformance of an automobile interior with theaim of minimizing the influence of harmfulmaterials emitted from new cars.
Experimental Study on the Combined Effect of Outdoor Thermal-Environment and Ventilation Patterns on Indoor Thermal-EnvironmentControl for Summer | 2008 | English
If thermal insulation and solar control ofbuilding envelopes are appropriately made forindoor thermal environment control, then themoderate air current becomes relativelyeffective for thermal comfort especially inresidentional buildings in summer
Recently, dampness in buildings has beenindicated to be associated with occupants' healthdamages such as allergies. In particular mold inindoor air is considered to be a significant riskfactor of health.
Misawa Homes have developed a homeaiming a zero annual energy balance, definedas the energy consumption over production byusing solar energy, in 1997.
Energy analysis of a personalized ventilation system in a cold climate: Influence of the supplied air temperature | 2008 | English
TII this study the influence of temperature of thesupplied air of a personalized ventilation systemon energy need has been investigated by meansof simulations with IDA-ICE software.

There are some ways to promote natural ventilation, but this research focuses on chimney which is traditional ventilation method used for industry or fireplace.
Building performance can be expressed bydifferent indicators as primary energy use,environmental load andlor the indoorenvironmental quality and a building performancesimulation can provide the decision maker with aquantitative measure of the exte
Numerical Simulation of Natural Ventilation Performance of SolarChimney with Built-in Phase Change Material | 2008 | English
This paper presents a study of solar chimneysusing a Phase Change Material (PCM)integrated into the heat absorber of the solarchimney.
Analysis for Wood Decay within Building Envelops Considering Moisture Production by Biochemical Reactions | 2008 | English
In this study, a durability assessment model forbuilding envelopes design based onhygrothesmal and wood rot decay analysis ispresented.
Tall buildings have traditionally been sealed andmechanical ventilated. In recent years advanceshave been made allowing the natural ventilationof tall buildings for a part of the year.
Solar Thermal and Electric Desiccant Cooling System,Part 1 : System Development and Investigation | 2008 | English
Environmental degradation, depletingconventional energy resources, and explodingworld population are indeed serious issues.Development of clean energy resources togetherwith clean technologies for human comfort is awonderful hunian creativity.
In predicting flow rate of a cross-ventilatedbuilding, discharge coefficients obtained fromthe connected value of resistance coefficient ofopening based on the chamber method, and thewind pressure coefficients from a sealedbuilding are usually use
Some Effects of Ventilation on People: Perceptions, physiologicalResponses and Mental Performance | 2008 | English
