Energy consumed in the Canadian residential sector for space cooling has more than doubled from 1990 to 2002. Cooling requirements, expressed by cooling degree-days have also increased.
A push-pull fume cupboard is a device to capture chemical vapors in a laboratory or a factory.
Conventional air-conditioning control in a roomassumes perfect diffusion of temperature in theroom, and relies on a temperature sensorinstalled on the wall or ceiling of the room, or inthe return duct.
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.
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.
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.
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.
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.
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.
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.
Natural ventilation systems in multi-familyresidential buildings should meet the needs ofreducing ventilation heat loss as well asproviding good indoor air quality.
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.
