Study on energy conservation effects of wind-induced ventilation indetached house using coupled simulation of semi-empirical ventilationmodel and network models | 2008 | English
A semi-empirical ventilation model was proposed for cross-ventilation. This model isbased on local dynamic similarity theory andwas coupled with COMIS and TRNSYS, whichare widely used for energy conservationsimulation.
Applying the activated carbon fiber filter supported with copper oxide catalyst to remove indoor VOCs | 2008 | English
HVAC (Heating, ventilating air conditioning)system is used to keep indoor air quality. Thepurpose of the traditional HAVC system isproviding a comfortable environment andventilating the indoor air pollutants.
Cool-Radiant and Dry Exergies Available from the Ceiling with an AtticSpace Conditioned by an Air-Conditioner | 2008 | English
A radiant cooling system with the use of anordinary air conditioner in attic space, whichmay cope with natural ventilation, wasdeveloped as a trial.
designed "air-curtain chemical fume hood" arediagnosed by using the tracer gas concentrationdetection method.
Upgrading the energy performance of office buildings in Greece -Trends and potentials. | 2008 | English
In this paper the energy performance and thepotentials of the energy savings decrease in twooffice buildings in northern Greece areexamined, within the frames of a renovationproject in office buildings of the public sector.Energy audits and simula
Full scale experimental evaluation of ventilation strategies of a double-skinfacade | 2008 | English
A double-skin facade is installed in a laboratory full scale test cell. The double-skin fagade has a 20 cm wide air cavity with Venetian sun-shading blinds and is provided with mechanical ventilation.
Equalization of wind pressure on the inner wall of double-skin of tall buildings for the natural ventilation | 2008 | English
This research concerns natural ventilation of the building with double-skin.
Evaluation of the solar-assisted desiccant air-conditioning systems using periodically reactivated desiccant beds under hot and humid CK climates | 2008 | English
In hot and humid regions, cooling anddehumidification are important issues of inindoor environment.
Numerous studies and everyday experiencesprove the fact that even new buildings do notperform as expected.
Double-skin facade (DSF) is an architectural/ engineering solution developed from the need to increase comfort in buildings with full glazed facades.
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
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.
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
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.
