The book of proceedings from the 26th AIVC Conference  "Ventilation in relation to the energy performance of buildings", Brussels, Belgium, 21-23 September 2005.
The 26th AIVC Annual Conference took place in Belgium at the Hotel Husa President Park, located in Brussels.
This paper investigates the sensitivity of indoor humidity models to the numerical description of water vapour buffering in porous materials in the room.
Janssens A., De Paepe M.
The performance of three different ventilation systems in cold climate homes is discussed.
Walker C.E., Kosar D.
The hybrid ventilation systems have been widely used for livestock barns to provide optimum indoor climate by controlling the ventilation rate and air flow distribution within the ventilated building structure.
Wu Z., Heiselberg P., Stoustrup J.
Studies on air circulation became of great importance in recent years, since are crucial for the energy consumption of buildings, for the pollutant dispersion within cities and for the good comfort conditions for the pedestrians and the habitants.
Georgakis C., Santamouris M.
High levels of indoor relative humidity are one of the main causes of moisture damage in buildings. That cause can be removed by an appropriate ventilation system.
Woloszyn M., Shen J., Mordelet A., Brau J.
The design and realisation of natural ventilation systems is an important research topic into the ability of buildings to respond to climatic conditions, using parts of the buildings themselves as indoor microclimate control systems.
Iannone F., Fiorito F.
This work presents simulations results exploring the influence of the building air-tightness on the energy consumption of buildings for different hypothesis on the type of ventilation system.
Voeltzel A., Carrié F.R.
The probabilistic model (PROMO) applied to the problem of air infiltration in low-rise buildings is presented. The PROMO model allows the estimation of the effect of variations of climaticconditions on air exchange in a building.
Pietrzyk K., Hagentoft C.E.
The paper presents a study of the indoor climate of a monumental building with periodic high indoor moisture loads. Several scenarios of the past performance and new control classes are simulated and evaluated.
Van Schijndel A.W.M.
Currently, various studies have demonstrated some doubt about the accuracy of the orifice equation when applied to the calculation of cross-ventilation.
Hiyama K., Kato S.
This article describes five blower door measurements – each made with a different objective – carried out on large buildings.
Dorschky S., Simons P., Rolfsmeier S.
This project aims to demonstrate via a refurbishing operation, how a mechanical ventilation system can both provide a good indoor air quality and limit the energy consumption due to air renewal.
Vialle P.J., Voeltzel A., Pico C.
Thermal comfort in living rooms or bedrooms is among others determined by the spatial distribution of the supplied ventilation air.
De Neve J., denys S., Pieters J.G., Pollet I., Denul J.
Natural night ventilation is an energy efficient way to improve thermal summer comfort. Coupled thermal and ventilation simulation tools predict the performances.
Breesch H., Janssens A.
Introduced for the first time at 25th AIVC Conference in Prague in September 2004, the HR-Ventproject still delivers new rich teachings since its start in January 2004.
Savin J.L., Berthin S., Jardinier M.
The commercial general - purpose Computational Fluid Dynamics (CFD) code PHOENICS is used to study the indoor environmental conditions of a large, mechanically ventilated, athletic hall.
Stathopoulou O.I., Assimakopoulos V.D.
Building materials and furnishing used in contact with indoor air have some effect to moderate the variations of indoor humidity in occupied buildings.
Rode C., Peuhkuri R., Hansen K.K., Time B., Svennberg K., Arfvidsson J., Ojanen T.
Ventilation in buildings is necessary first for hygienic reasons and also to preserve the building structure. This is more essential, today, because the buildings are more and more airtight, mainly due to energy regulations.
