This paper presents a design method to definethe settings of HVAC systems in order toprovide thermal comfort in high MRTenvironment in hot climates.
The holistic aim of this study is to make clearthe possibility of passive cooling systems usingnatural cool sources produced by cyclic weatherchanges. Here in this study, we focused on apossible use of rainwater for cooling.
The IEA ECBCS: Research and Development for Near Zero Energy and Carbon Emissions in Buildings and Communities | 2008 | English
The Energy Conservation for Buildings andCommunities Systems (ECBCS) is anImplementing Agreement among 23 countriesof the IEA (International Energy Agency) forenergy research and development in buildingsand communities.
Conflation of computational fluid dynamics(CFD) and building energy simulation (BES)has been used in recent years in order toimprove the estimation of surface coefficientsfor studies on thermal comfort, mold growthand other performance aspects of
Recently, supplying glass space like atrium isbeing extended widely for introducing naturallight into a building, improving rest roomfunctions and having a pleasant workenvironment.
People who become too warm or too cool willadjust their clothing or reset building controls(windows, blinds, fans, thermostats) with theainz of restoring comfort or reducingdiscomfort, if they are free to do so.
Thermal adaptation in residential buildings in the Hot Summer and WinterCold Zone of China, case study of Wuhan in summer | 2008 | English
This field work was conducted in Wuhan in2007 summer to investigate local residents'thermal adaptation.
In recent years, the insulation and air-tightnesslevels of newly constructed houses in Japanhave been improved for purpose of energysaving. However, a reduced design of airpermeability (i.e.
Translucent thermal insulation walls forJapanese houses have been designed to allowsolar radiation and daylight to pass through thewalls into the house (Fig.
In order to further improve energyperformance of buildings, intelligentbuilding control is needed which integratesindividual demands and behavior ofoccupants.
In residential buildings moisture is adominant pollution source removed by theventilation system. The Danish buildingcode requires a minimum air change rate of0.5h-1 in residential buildings to avoidmoisture related problems.
A Study on Wind Pressure Coefficients of Residential Buildings andSimplified Prediction of Air Change Rate by Cross-Ventilation | 2008 | English
This study was carried out systematically asfollows; at first, an investigation of grossbuilding-to-land ratio of real residential areawith GIs data was carried out.
The primary purpose of the present study was toevaluate the effects of retrofitting of windowsashes by measuring air tightness performanceand thermal environment of apartment housesbuilt during the period 1965 - 1974 before andafter the retrofitti
During the past half century, filtration techniques based on the use of activated carbons have been widely used in industrial applications, and considerable knowledge about the mass transfer processes involved has been developed.
Natural ventilation systems in multi-familyresidential buildings should meet the needs ofreducing ventilation heat loss as well asproviding good indoor air quality.
Thermal building simulations (TRNSYS) werelinked to nodal airflow network simulations(COMIS) for a detailed ventilated double-skinfacade calculation of performance.
