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.
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.
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.
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.
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.
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.
This paper presents simulation results of the performance of ventilation systems with self-regulating inlets in different types of typical Flemish dwellings.
Combined heat, air and moisture (HAM) simulation at the envelope level and building simulation havebeen two separate activities for many decades now.
On the impact of urban environment on the performance of natural and hybrid ventilation systems | 2005 | English
The impact of the urban environment on natural and hybrid ventilation was investigated through experimental and computational procedures in the framework of RESHYVENT European Project.
In today’s architecture, innovative concepts, such as double skin facades, for the building skin are developed to improve the energy performance of a building and at the same time improve the indoor climate of the building.
Criteria to define limits for building airtightness. Airtightness of some Portuguese dwellings | 2005 | English
The increasing concern on energy conservation in buildings and the increasing insulation level of buildings, lead to the introduction of limits for building airtightness, to minimize building heat losses.
There are many research works for the moisture buffering effect of the building materials.
Energy and comfort performance of natural ventilation system office buildings in China | 2005 | English
This paper presents an analysis of energy and comfort performance of typical office buildings for summer cooling in five climate zones in China using the natural ventilation assessment tool, which is developed based on the integrated thermal and a
Experimental characterization of hybrid ventilation systems in residential buildings | 2005 | English
In the recent past, residential buildings in temperate climates were ventilated by the daily opening of windows and by exaggerated window and door permeability.
Heat and non-heat recovery ventilation performance in energy-efficient hud-code manufactured housing | 2005 | English
The Zero Energy Manufactured Home Project demonstrates and promotes innovative energy saving technologies to the manufactured housing industry and home buying public, while evaluating those technologies energy performance.
In 1998, Persily published a review of commercial and institutional building airtightness data that found significant levels of air leakage and debunked the myth of the airtight commercial building.
