European Directive for Energy Performance of Buildings (EPBD) was approved in the beginning of2003. The transition period is 3-6 years depending of the article.
Olesen B.W.
French buildings highly contribute to the total national energy consumption.
Sarrade L.,Manificat A., Corgier D.
Since the energy-crisis of the 70’ies, the trend goes to energy-saving constructions, that have strongly changed our way of building.
Leimer H.P., Toepfer I.
The aim of this work is to study the influence of global heat transfer coefficient (Utot en W/m2.K) of the opaque walls (walls and roofs) and of the glazed walls (bays) on the annual consumption of heating, cooling and overall consumption energy.
Filfli S., Marchio D.
The energy consumption of a building is evaluated by neglecting the heat loss which can occur when the air passes through the envelope.
Barhoun H., Guarracino G.
An Earth-to-Air Heat Exchanger (ETAHE) is a low energy cooling and heating technology for buildings.
Zhang J., Haghighat F.
In this study the COwZ model (COMIS with sub-zones) was modified to allow dynamic simulations ofindoor thermal conditions, humidity and pollutant transport and concentrations throughout wholebuildings.
Ren Z., Stewart J.
The thermal exchanges between the buildings and its surroundings may be easily evaluated from balance equations.
Palme M., Isalgue A., Serra R., Coch H.
The prediction of air infiltration is very important when simulating a building, due to the couplingaspects of the thermal and ventilation problem.
De Castro E.P.B., Virgone J.
The actions to limit the energy consumption and the electricity demand lead in Europe and inFrance to think about the energy labelling of the consumption of the fans used in ventilationsystems.
Vialle PJ., Barbat M., Collignan B.
The paper discusses a methodology for thermal analysis applied to buildings in which the stochasticnature of the external forces is concerned. The considered forces are ambient temperature and solarradiation.
Abida M., Lefebvre G., Ghrab-Morcos N.
In this study the question whether or not and to what extend ventilation and air cleaning can contribute to the reduction of exposure to environmental tobacco smoke in the hospitality industry is answered.
De Gids W., Jacobs P.
As a large part of the education year occurs during the cold weather season, the proportionally largeglass areas permit excessive heat loss in the classrooms.
Zorer Gedik G. , Koyun A. , Yilmaz T.
The idea proposed in this paper is to control the HVAC equipment with predicting the heating/cooling loads and indoor conditions by computational simulation according to the target, such as energy consumption, energy cost, CO2 generation and indoo
Utsumi Y., Mitamura T., Kamimura K.
In most conditioned spaces, the Mixing Jet Ventilation (MJV) systems are commonly installed. Relying on turbulent mixing, MJV homogeneously controls the room environment.
Varodompun J. , Cotel A.J.,. Navvab M.
The use of heat produced by solar thermal collectors is an interesting option for thermal driven airconditioning process. Three technologies are commercially available: absorption, adsorption anddesiccant cooling systems.
Vitte T., Brau J., Chatagnon N.
The joint IEA research project of ECBCS Annex 43 / SHC Task 34 “Testing and Validation of Building Energy Simulation Tools” contributes to evaluation, diagnosis and improvement of building energy simulation tools.
Felsmann C.
Regular maintenance, such as the cleaning of filters, is important for the efficient operation ofresidential ventilation systems.
Tajima M., Sawachi T., Mineno S., Murata S.
For the conservation of an important museum collection in a historic building a better controlled indoor climate may be necessary. One of the most important factors is controlling relative humidity.
Neuhaus E., Schellen H.
The design of ventilation equipment is important because it affects the ventilation performancedirectly. To improve the ventilation efficiency of the displacement ventilation, a new ventilation system was proposed in this study.
