Canadian research into residential ventilation and combustion venting revealed that the installed performance of exhaust equipment, ducting passages, and…
A demand controlled air ductwork should be so dimensioned that the flow controllers have good flow and acoustical operation conditions. From the air flows…
Measurement methods based upon multiple tracer gas techniques have become an established branch of the study of air infiltration and interzonal air…
It is particularly important to be aware of the air flow pattern in a building when determining indoor air quality problems or calculating space…
The COMIS workshop (Conjunction of Multizone Infiltration Specialists), using a multi-national team, is planning to develop a reliable, smooth running…
A new visual method is yielded by a particular application of Mollier's h,x-diagram. Point fields (temperature and humidity) lead to a significant…
In Sweden, the energy crisis in the early seventies resulted in attempts to lower the air change rate in buildings to reduce energy consumption. For many…
An up-to-date design concept for office buildings results in a very low energy consumption and provides a better indoor climate at the same time. This new…
In order to be validated, the computer programs simulating the air flows in multizone buildings need several measured data sets to be compared with. Such a…
This paper explores the results of air infiltration and ventilation research carried out in Canada over the last decade and specifically examines its…
Displacement flow systems are becoming popular, especially in Scandinavia, for comfort ventilation. In these systems air is supplied near the floor at low…
Building codes that address radon control in residential buildings are a relatively new development in the larger trend toward increased efforts to…
The air change rate in existing, older blocks of flats having natural ventilation has been measured by the tracer gas method. Measurements were made in the…
The paper describes the development in airflow simulations in rooms. The research is, as other areas of flow research, influenced by the decreasing cost of…
Ventilation, infiltration, indoor air flows and air exchanges determine two aspects of fast growing interest: the energy balance of buildings and the indoor…
A test room with a Displacement Ventilation System has been built. Air velocity and temperature profiles were measured at different places in the room under…
This paper presents a new technique for supply of outdoor air directly through external walls into a dwelling room without any draught problems. A new type…
Rising moisture from the ground has caused quite a lot of damage on foundations of Swedish buildings. It is in some constructions possible to prevent this…
France is one of the European countries where ventilation has the most advanced regulation. Vertical ducts have been used for a very long time, making…
Whole-building pressurisation tests can quantify the air-leakiness of a building's external envelope. The resulting information can be used in assessing the…
