Industry-wide methods of assessing duct leakage are based on duct pressurization tests, and focus on highpressure ducts.
Development of design guidelines for tertiary sector buildings equipped with natural ventilation systems | 2005 | English
This study considers the link between tertiary buildings design and equipments known as natural and hybrid ventilation or cooling.
At the conceptual design stage, one needs to pay considerable attention to both the energy as well as indoor air quality (IAQ) requirements.
Study on energy conservation effect of hybrid ventilation system utilizing wind pressure for multi-family buildings | 2005 | English
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
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).
Airtightness field measurement study of 123 new french dwellings with a simplified measuring device | 2005 | English
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).
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.
An earth-air heat exchanger (EAHX) has been implemented in a low-energy office building in Kortrijk,Belgium.
Experiment of the mixing property and the heat exhaust effect under cross ventilation in a full-scale building model. | 2005 | English
Cross ventilation is one of the most important techniques for achieving energy conservation and for maintaining a comfortable indoor environment in summer.
Direct expansion (DX) air conditioning (A/C) systems are most commonly used in residential buildings in hot and humid subtropics.
This article describes five blower door measurements – each made with a different objective – carried out on large buildings.
Currently, various studies have demonstrated some doubt about the accuracy of the orifice equation when applied to the calculation of cross-ventilation.
