Pre-assessing the reliability of ventilation systems is a dificult task and no simple methodshave existed. This paper presents a tool for estimating the…
The principles of a new tracer gas technique is described in the paper. The new technique involves pulse injection of tracer gas and has the same advantages…
Concentration of pollutants produced by car traffic in a street below the roof level has large spatial variations. In a street, pollutants are diluted by…
Natural ventilation in office buildings can sometimes offer other advantages than traditionalmechanical ventilation systems. Often natural ventilation…
This paper is concerned with heat and mass transfer through two typical staircases, The firststaircase connects the two individual floors of a two-storey…
This paper identifies successful ways of applying natural ventilation to non domestic buildings locatedin urban areas. Whilst noise and contaminant…
Based on the fundamental flow equations, a set of formulas is derived for air velocities, temperature differences and ventilation rates in relation to…
In this paper ventilation strategies are examined in order to improve the thermal performanceof an attached sunspace of a two-storey semi-detached house in…
Heat recovery in ventilation systems for office buildings in cold climates is necessary for tworeasons:1. To obtain acceptable indoor thermal comfort by…
A systematic analysis of recently constructed dwellings in the Flemish Region has beenundertaken within the SENVIVV-project (1 995- 1998) [I]. In total 200…
This study describes how the air quality in a displacement ventilated classroom can beinfluenced by the position of a contaminating person, and by the…
A dynamic simulation of the ventilation processes and the thermal behaviour of an office building is developed. This is used to investigate two aspects of…
Until now, there is no widely accepted way to express any index for this purpose and takinginto account the large variety of possible pollutants. Things can…
Modelling of indoor pollutant concentrations that varies in time can be a useful tool forestimation of the strength of internal sources and sinks. Usually…
The aim has been to determine ventilation rates and risk of moisture damage in three modernschools with passive stack ventilation. The users are supposed to…
Ventilation systems with heat recovery offer several advantages such as, of course, energy savings but also the possibility to add acoustic and filtration…
To conduct a controlled trial to test the ability of a newly developed electrostatic air cleaningtechnology (EAC) to improve Indoor Air Quality (IAQ) as…
Ventilation of buildings in urban areas may result in high internal concentrations of traffic pollutants if air intakes are positioned where external…
The Swedish Parliament decided 1991 that ventilation systems in all non-industrial buildingsshould be regularly inspected in intervals from 2 to 9 years,…
