LoginVentilation 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.

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.
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.
There are many research works for the moisture buffering effect of the building materials.
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.
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.
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.
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.
Ventilation related to user habits. Considerations on Environmental Envelope Rehabilitation | 2005 | English
Application of ventilation techniques, as well as the use of any passive environmental solution in a rehabilitation, requires knowledge of the particularities of the climate and the specific characteristics of the building stock.
Natural ventilation reduces energy consumption for fans and mechanical cooling and in mostcases gives occupants control over their office space. Further benefits include no fan noise and insome cases elimination of the mechanical cooling system.
Indoor environmental quality, energy usage and occupant perception in commercial office buildings | 2005 | English
A multi-disciplinary study to comprehensively measure and analyze operational performance and indoor environmental conditions in a sample of typical, commercial office buildings in the United States is described.
Review on ventilation rate measuring and modelling techniques in naturally ventilated buildings | 2005 | English
Direct and indirect measuring techniques are available for determination of ventilation rate in naturally ventilated buildings.
An on-line mathematical approach was used to model the spatio-temporal temperature distribution in an imperfectly mixed forced ventilated room.
This study investigates numerically the occurrence and duration of higher relative humidities in a cold attic space, which are a consequence of excessive moisture supply from ventilating the attic and from air infiltration from inside the dwelling
This paper presents the results of a field study conducted on 31 houses owned by a French social housing management body.
Prediction of buoyancy-induced pressure difference across exterior walls of high rise residential buildings | 2005 | English
It is very important to estimate the stack pressure difference across exterior walls for understanding the energy impacts of infiltration and ventilation in high-rise buildings, because stack pressure is likely to significantly affect energy load
Impact of commercial building infiltration on heating and coolin loads in US office buildings | 2005 | English
With the exception of a few analyses of the impacts of ASHRAE Standard 62-89 and energy use in specific buildings, the energy use in commercial building due to infiltration and ventilation flows has received little attention.
The present paper presents the results of the energy and environmental evaluation of ten school buildings in the Greater Athens Area.
