Evaluation of the solar-assisted desiccant air-conditioning systems using periodically reactivated desiccant beds under hot and humid CK climates | 2008 | English
Numerous studies and everyday experiencesprove the fact that even new buildings do notperform as expected.
Subjective experiments on the suitable illuminance in a living room daylitby Mirror Duct System | 2008 | English
The objective of this study is to identify theeffects of mirror duct system on energy savingsfor luminaries.
Today lots of research and application of solarheating are focused on continuously occupiedbuildings, such as residential buildings.
Impact of the Change of Gross Building-to-Land Ratio upon the ResidentialVentilation Usage and Energy Consumption for Air-Conditioning andLighting | 2008 | English
Tn this paper, using thc "SCTENCE vent"method for estimating the energy consumptionfor air conditioning in rcsidcntial buildings, wcevaluated the wind environment and theradiative conditions with respect to the targetbuildings in the case where th
Thermal mass activation (TMA) can assure, incertain cases, thermal comfort conditionswithout the need of air conditioning systems.Even if other cooling systems have to be used,night ventilation significantly reduces theduration of the working time
There are many technologies aimed at reducing energy demand of ventilation systems, but thefocus in these designs has remained on the airheating system and exhaust losses.
Activated carbon filters have been used forpurification of air and water in industrialapplications.
Considering density of housing in residentialarea of large cities in Japan, it is very difficultto secure sufficient daylight and lead daylightto whole space in the house. High side lightingis one of solutions for such situation.
Parameter Estimation of Dynamic Multi-zone Models for LivestockIndoor Climate Control | 2008 | English
In this paper, a multi-zone modeling concept isproposed based on a simplified energy balanceformulation to provide a better prediction of theindoor horizontal temperature variation insidethe livestock building.
In the recent years in Latvia is rapidlydeveloping construction sector of residentialbuildings. Engineers have to give moreattention to heating and cooling system'stechnology in the buildings to stay competitivein the realty's market.
Recently, natural ventilation, which istraditional cooling method in Japan, hasbecome considered as the key method forcooling energy conservation.
Contrastive analyses on annual energy consumption between new residential buildings and old residential buildings in Shianghai, China | 2008 | English
The purposes of this research are to contrast theenergy consumption characteristics of oldresidential buildings and new residentialbuildings in Shanghai, China, and to analyzeinfluence factors of residential energyconsumption.
Wind prefiltering and Indoor Air Quality in the vernacular architecture ofhot arid regions of Iran. | 2008 | English
The results of a recent research and it'sstatistical analysis, show that in some of theIranian cities like YAZD, there are two periods(from end of august to end of September andfrom end of February to end of March) in whichoutdoor pollution is hig
Interference Coefficient for Discharge Coefficient in Prediction of CrossVentilation Rate through Large Openings | 2008 | English
In predicting the cross ventilation rate throughlarge openings, the use of general dischargedcoefficient , values for the conventionalorifice equation is not suitable.
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.
