Ventilation, Humidity Control and Energy : A Tightrope of Challenges and Opportunities | 2003 | English
This paper is a keynote address presented at Ventilation, Humidity Control and Energy 24th AIVC Conference.It is a warning for HVAC professionals that are however walking a tightrope.
Simplified measurement techniques for health visitors to assess indoor environments | 2003 | English
There 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.
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
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.
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.
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.
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.
Passive cooling strategies require strict adherence to the physical world.
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.
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.
Cavity wall is often proposed in the building envelope design as a solution for improving the thermal comfort of the inhabitants and reducing the adverse condensation effects on the building fabric.
For the building team, the design of library, archives and museum facilities brings with it special responsibilities. Archive and conservation facilities require the highest levels of preservation and maintenance of the building environment.
Can adventitious ventilation negatively impact moisture performance of building envelopes in moderate climates ? | 2003 | English
In moderate climates, adventitious ventilation helps in keeping the water vapor balance in a building under control. This does not hold in hot and humid climates, where the outside air is a moisture source.
In recent years, poor indoor climate has caused health problems for building occupants.
A manufactured home has been installed on the NIST campus for ventilation, energy andindoor air quality studies. The primary purposes of the facility are to study mechanicalventilation requirements for U.S.
