The Decision-making Process for Material and Ventilation Rate consideringIAQ and Cost in Apartment Buildings | 2008 | English
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.
Misawa Homes have developed a homeaiming a zero annual energy balance, definedas the energy consumption over production byusing solar energy, in 1997.
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.
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.
Study onAirflow around Building Roof for Design ofNatud Ventilation by Chmney- Part1 Distribution of wind pressure coefficient on a building roof - | 2008 | English
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
Distribution of contaminants in the occupied zone of a room served by a novel enhanced displacement ventilation system | 2008 | English
The aim of this study is to examine contaminantdistribution in the occupied zone of a room servedby a novel enhanced displacement ventilationsystem which brings cooler air near the floorupward around human body via 4 fans mounted ateach corner of
The concentration in the convection flows ofresuspended particles from the floor area wasexperimentally investigated under laboratoryconditions with different ventilation strategies.It was concluded that the number of smallparticles transported in
In building design the requirements for energyconsumption for ventilation, heating and coolingand the requirements for increasingly betterindoor climate are two opposing factors.This paper presents the schematic layout andsimulation results of an
The use of floor heating has been know sincemore than 3000 years from the Chinese Kang,the Korean Ondol, the Romans hypocaust to daysmodern water based systems embedded in thefloor construction.
Effect of technical solutions on non-heating and non-cooling temperatures and free cooling potential in office buildings | 2008 | English
In this paper we analyze by means ofbuilding simulation the effect of differentparameter combinations on the non-heating andnon-cooling temperatures of a typical airconditionedoffice building.
The Mechanical supply only (MSO) ventilationsystem has many advantages, such as good airdistribution, easy pre-heating of cold fresh airsupply and prevention of chemical aerosolsintake through wall cavity.
Adaptive Mesh Refinement Method Suitable for CFD Analysis of WindEnvironment around Buildings | 2008 | English
In order to generate effective grid for CFDanalysis of wind environment around buildings in urban area, we newly develop non-uniformtype adaptive mesh refinement method(NUAMR).
Advanced Distribution and Decentralized Supply : A Network Approach for Minimum Pressure Losses And Maximum Comfort | 2008 | English
The paper presents a new concept for a lowpressure drop supply system suited for theventilation of office spaces.
Domain decomposition technique is a methodfor CFD simulation, which can handle internalairflow of cross-ventilation of dwellingsseparately from extemal domain.
We are building a particle tracking systemfor the measurement of convective heat transfersand pollutants displacements in full scale rooms.To increase the depth of the zone of interest, thesystem is non stereoscopic and do not use laserlight.
