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.
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.
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.
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.
An Earth-to-Air Heat Exchanger (ETAHE) is a low energy cooling and heating technology for buildings.
Zhang J., Haghighat F.
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 thermal exchanges between the buildings and its surroundings may be easily evaluated from balance equations.
Palme M., Isalgue A., Serra R., Coch H.
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.
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.
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.
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 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
