Industry-wide methods of assessing duct leakage are based on duct pressurization tests, and focus on highpressure ducts.
Wray C.P., Diamond R.C., Sherman M.H.
This study considers the link between tertiary buildings design and equipments known as natural and hybrid ventilation or cooling.
Van Moeseke G., Bruyère I., De Herde A.
At the conceptual design stage, one needs to pay considerable attention to both the energy as well as indoor air quality (IAQ) requirements.
Sekhar S.C., Tham K.W, Cheong K.W.
According to the R&D Project on Low Energy Housing with Validated Efficiency, the CO2 emissions due to operation of ventilation systems are estimated to be 7 to 12% of total CO2 emissions of a unit of multi-family buildings in mild climate reg
Tajima M., Sawachi T., Hori Y., Takahashi Y.
In these last years, a great deal of interest has been devoted to double-skin façades due to the advantages claimed by this technology (in terms of energy saving in the cold season, high-tech image, protection from external noise and wind loads).
Gratia E., De Herde A.
Studies on buildings’ airtightness have shown that several issues can arise from uncontrolled airflow leakages in buildings (e.g., higher energy cost, thermal comfort and health of occupants, building components and equipment preservation).
Litvak A., Voeltzel A., Boulanger X., Markiewicz R., Royet B.G.
As a result of the EPB directive, the Flemish government has established a new regulation due as from January 1ste, 2006. This regulation also imposes the presence of minimal ventilation equipment in new buildings.
Wouters P., Van den Bossche P.
An earth-air heat exchanger (EAHX) has been implemented in a low-energy office building in Kortrijk,Belgium.
Janssens A., Steeman M., Desmedt J., Hoes H., De Paepe M.
Cross ventilation is one of the most important techniques for achieving energy conservation and for maintaining a comfortable indoor environment in summer.
Nishizawa S., Sawachi T., Narita K., Seto H., Ishikawa Y., Gotou T.
Direct expansion (DX) air conditioning (A/C) systems are most commonly used in residential buildings in hot and humid subtropics.
Zheng Li, Wu Chen, Shiming Deng
This article describes five blower door measurements – each made with a different objective – carried out on large buildings.
Dorschky S., Simons P., Rolfsmeier S.
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.
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.
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.
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.
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.
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.
Barles P., Vialle P.J., Lemaire M.C.
This paper presents simulation results of the performance of ventilation systems with self-regulating inlets in different types of typical Flemish dwellings.
Willems L., Janssens A.
