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).
Direct expansion (DX) air conditioning (A/C) systems are most commonly used in residential buildings in hot and humid subtropics.
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.
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.
CFD analysis of the effect of self-regulating devices on the distribution of naturally supplied air | 2005 | English
Thermal comfort in living rooms or bedrooms is among others determined by the spatial distribution of the supplied ventilation air.
Uncertainty and sensitivity analysis to evaluate natural night ventilation design in an office building | 2005 | English
Natural night ventilation is an energy efficient way to improve thermal summer comfort. Coupled thermal and ventilation simulation tools predict the performances.
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.
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.
Building materials and furnishing used in contact with indoor air have some effect to moderate the variations of indoor humidity in occupied buildings.
Assessment of improvement brought by humidity sensitive and hybrid ventilation/HR-Vent project | 2005 | English
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.
