To better quantify the impact of different window opening models in comparison to ventilation techniques a multizone ventilation model, incorporating the CO2-production of the inhabitants, was developed, using Comis-Transys.

Impact of residential natural ventilation and air-tightness techniques on the energy loss and indoor air quality | 2003 | English
For historical and demographical reasons, in many European countries, an important part of educational building must be retrofitted.
Assessment and description of humidity controlled system in french residential buildings | 2003 | English
In France, ventilation in new residential buildings must be designed and dimensioned according to the Health regulation (Arrêté du 24 mars 1982) which is basically based on required extract air flow rates.
In order to facilitate nationwide analysis of ventilation and indoor air quality issues in residential buildings, a set of homes has been defined to represent the housing stock of the United States.
The airtightness of a building envelope impacts upon the magnitude of uncontrolled air leakage and associated ventilation energy losses. A building's airtightness can be assessed using a steady state fan pressurisation technique.
A comparison of residential ventilation codes and standards requirements in cold climate areas of the United States of America, Canada and selected northern european countries | 2003 | English
The study reviewed each Code/Standard with respect to requirements relating to acommon set of ventilation factors and criteria. The main factors include the following:1.
Passive cooling strategies require strict adherence to the physical world.
User "friendly" residential ventilation system control strategies and effectiveness | 2003 | English
The most efficient ventilation system would only operate on demand, when ventilation was "needed".
This is a personal set of comments giving the author's impressions of the papers presented at the conference.
A Demand Controlled Hybrid Ventilation System is a two-mode system using natural forces as long as possible and electric fans only if necessary.
An experimental campaign was organized during the summer period 2002 in Athens, in the framework of the European RESHYVENT Project.
Natural night ventilation and an earth-to-air heat exchanger are applied in the low-energy office building ‘SD Worx’ in Kortrijk (Belgium).
Infiltration has traditionally been assumed to contribute to the energy load of a building by an amount equal to the product of the infiltration flow rate and the enthalpy difference between inside and outside.
In Arctic and sub-Arctic climates, such as those in Scandinavia, multiple-glazing windows that consist of at least three panes are widely used.
This paper deals with the real behavior of a humidity controlled air inlet, regarding to relative humidity and temperature.
Building envelope, duct leakage and HVAC system performance in HUD-code manufactured homes | 2003 | English
Between 200,000 to 300,000 manufactured homes are built to the US Department of Housing and Urban Development’s Manufactured Home Construction and Safety Standards (MHCSS) in the US each year.
The peak electrical demand of office building VAV systems will be reduced by about 1.2 Kw/1000 Ft2 by employing an Integrated Systems Demand Control Technology (ISDCT) sequence to reduce peak intake flow by about 56%.Supply, return, and exhaust fa
During the last 20 years, the humidity sensitive ventilation system evolved to products increasingly simplified thus standardised.
In the 1990's, concern about global warming has resulted in a resurgence of interest in naturally ventilated offices. The Belgian climate is particularly well adapted to apply cooling by natural ventilation.
Increasing emphasis on energy-efficiency has many jurisdictions enacting stricter energy codes.
