LoginThere is research acknowledging that the home environment may be responsible for worsening respiratory conditions, especially for children. The indoor environment is a substantial source of exposure to pollutants e.g. environmental tobacco smoke.

Simplified measurement techniques for health visitors to assess indoor environments | 2003 | English
Developing virtual laboratories for the design and test of ventilation control strategies | 2003 | English
The control industry integrates more and more recent innovations, especially on the sector of communication networks (bus), control (fuzzy logic, neural networks...) and informatics (hard-and software) for the development of Building Automation an
Reshyvent - A EU cluster project on demand controlled hybrid ventilation for residential buildings | 2003 | English
In January 2002 the EU RESHYVENT project started, a three-year project within the EU Fifth Framework Programme on the investigation and development of demand controlled hybrid ventilation systems in residential buildings.
Experimentation : humidity controlled system in french collective buildings refurbishment | 2003 | English
In France, most of the public project managers have collective dwellings built in the 70’s 80’s with first generation mechanical ventilation systems.
Impact of residential natural ventilation and air-tightness techniques on the energy loss and indoor air quality | 2003 | English
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.
For historical and demographical reasons, in many European countries, an important part of educational building must be retrofitted.
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.
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.
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.
In the survey study ‘Kantoor 2000’ the HVAC-system of several large office buildings in Flanders was monitored. Some of these buildings use air humidity control, most of them not. This triggered the question : why?
Mold in dwellings is a persisting complaint in moderate climates.
For energy savings, DCV systems are more and more used in ventilation systems. In France, in nonresidential buildings, these systems are generally controlled by either a CO2 sensor, or an opticalmovement detection (infrared).
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
