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

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.
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.
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.
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.

Gas phase filters have been installed within the air handling unit of an HVAC system feeding 100 %fresh (outdoor) air to an office building.
Ginestet A., Pugnet D.
Positive input ventilation (PIV) systems were installed in a new build housing development inBallantrae in south west Scotland; utilising a glazed sunspace on the south elevation of each dwelling to augment the energy saving potential of the insta

To gain access to information on energy use in office buildings, the German Federal Ministry forEconomy launched an intensive research and demonstration programme in 1995.
Voss K., Herkel S., Löhnert G., Pfafferott J., Wagner A.
Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climateis, however, being questioned.
Blomsterberg A.
Modelling thermal and aerial behaviour of unconditioned buildings requires an accurate knowledge of the air temperature and velocities fields inside the considered spaces.
Gharbi L.,.Ghrab-Morcos N., Roux J.J.
Balanced ventilation systems with heat recovery and earth to air heat exchangers are interestingtechniques, which can reduce heating and cooling demand of buildings, and improve internal thermal comfort.
Chlela F., Husaunndee A., Inard C., Kartachi Y., Riederer P.
The optimization of building thermal performance has traditionally been based on designers’ experience.
Conraud Bianchi J.,Mengistu T., Haghigat F., Ghaly W.S.
The average air tightness of the ventilation ductwork in France is rather poor, corresponding toa 3A class. This is mainly due to air leakage in the fittings.
Vialle P.J.
Application of scale models along with the use of wind tunnel testing facility have been the primary tool used in building aerodynamic studies by architects and planners.
