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.
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 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.
Moon J.H., Heo J.H., Moon S.J., Lee J.H.
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.
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.
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
Currie J., Capper G., Holmes J.
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.
Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climateis, however, being questioned.
Blomsterberg A.
The optimization of building thermal performance has traditionally been based on designers’ experience.
Conraud Bianchi J.,Mengistu T., Haghigat F., Ghaly W.S.
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.
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.
Navvab M., Varodompun J.
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.
This article presents the application of the zonal approach for modeling airflow and temperaturedistribution in Doube-Skin Facades (DSF).
Jiru T.E., Haghighat F., Perino M., Zhanghirella F.
This presentation will make the audience aware of the importance of ISO-recognized certificationprograms in the testing adjusting and balancing and commissioning of HVAC systems.
Emblem E., Hamilton J.
The paper evaluates the potential work performance benefits of increased ventilation. We analysed the literature relating work performance with ventilation rate and employed statistical analyses.
Seppanen O., Fisk W.J., Lei G.H., Heinonen J.
In Cuba the climate is tropical, with average solar radiation of 5.5 kW-h/m2and an annual average temperature of 25 °C. The relative humidity is high all of the time, with an annual average between 75 % and 85%.
Carbonell T., De Paepe M., Quesada G.
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 paper presents the evaluation of the current HVAC components and indoor climate of a high tech Naval Depot in case of failure events.
Van Schijndel A.W.M., Schellen H.L., Timmermans W.J.
