Mechanical ventilation systems have been adopted in airtight energy- efficient houses in Canada to provide fresh air, remove moisture and indoor pollutants…
Outdoor air pollution can have a bearing on the effectiveness of indoor air and the quality of ventilation. There is a pressing need to reflect on the…
This paper tries to give a reasonable description of the state of the art of the Belgian building stock with regard to ventilation. The Belgian research…
This paper presents an analysis of indoor climate in buildings with forced air heating systems. The results is based on indoor climate measurements and…
To avoid the shortcomings and problems that occur in today's ventilation systems a ventilation concept for future dwelling-houses is under development. The…
Ventilation produced by fluctuating pressure differences across a building appears to have received little attention . Such fluctuations are produced by…
Increases in building air tightness for purposes of energy saving have, unfortunately, also led to a significant increase in the number of instances of…
This text contains comments to the poster presented at the 9th AlVC Conference in Gent, Belgium. The project under consideration in the poster (…
In displacement ventilation systems, air flow rates, temperature and the design of the air supply device strongly influence the parameters which decide the…
This work is concerned with measuring air flows between the floors of houses. A simple measuring technique is described in which two portable SF6 systems…
Air exchange rates in occupied buildings are difficult to assess due to their dependence on a multitude of climatic parameters and inhabitant behaviour.…
Tracer gas techniques for measuring airflow rates in building systems are considered. These techniques are classified in terms of tracer gas injection…
A constant concentration tracer gas (CCTG) measuring system needs a control algorithm to calculate, at each sampling time, the required tracer gas injection…
This paper reviews research activities undertaken in the framework of IEA Annex XIV, "Energy and Condensation". It outlines the objectives and working…
A unique multiple tracer experimental system has been developed and utilized within commercial buildings to monitor ventilation rates, air exchange…
Since thermal comfort on human body is influenced by the local air flow speed, it is needed to estimate the distribution of air flow speed in a room for the…
This work deals with problems of the air humidity in inhabited dwellings. A new approach is presented here which renders the definite diagnosis of humidity…
The technique of tracer gas measurement has during recent years tended towards increasingly complicated measuring methods. The new measuring techniques are…
An element-assembly formulation of multi-zone contaminant dispersal analysis theory is described. In this approach a flow system is idealized as an…
This paper deals with field experience of airborne moisture transfer problems in houses. Two types of phenomena are discussed in more detail; the…
