Pre-assessing the reliability of ventilation systems is a dificult task and no simple methodshave existed. This paper presents a tool for estimating the reliability of domestic ventilationsystems.
Natural ventilation in office buildings can sometimes offer other advantages than traditionalmechanical ventilation systems. Often natural ventilation systems are promoted at an earlystage by an architect, but perceived dificulties, e.g.
The principles of a homogeneous tracer pulse technique for measurement of ventilation and air distribution in buildings. | 1998 | English
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 as the previously known homogeneous emission technique.
Concentration of pollutants produced by car traffic in a street below the roof level has large spatial variations.
Ventilation systems using variable airflow are useful in urban areas. Due to outdoor pollutionand the indoor load from pollution or thermal sources, it is important to vary the airflow.
Displacement ventilation in a classroom - influence of contaminant positioning and physical activity. | 1998 | English
This study describes how the air quality in a displacement ventilated classroom can beinfluenced by the position of a contaminating person, and by the activity of a person who walksaround in the room.
Evaluation of thermal performances of residential ventilation systems with heat recovery. | 1998 | English
Ventilation systems with heat recovery offer several advantages such as, of course, energy savings but also the possibility to add acoustic and filtration treatment.
The paper describes the results of a Pan-European survey carried out on identifying thebarriers that restrict the implementation of natural or simple fan-assisted ventilation systems inthe design of new office-type buildings and in the refurbishme
This paper is concerned with heat and mass transfer through two typical staircases, The firststaircase connects the two individual floors of a two-storey building, and the other connectsthe three individual floors of a three-storey building.
Today, the development of new technologies to improve building envelope performances ishighly encouraged and provides a clear challenge for designers and researchers. In thiscontext several typologies of active envelopes have become very popular.
A systematic analysis of recently constructed dwellings in the Flemish Region has beenundertaken within the SENVIVV-project (1 995- 1998) [I]. In total 200 dwellings have beenexamined in detail.
Reentrainment of pollutants from exhausted air - discussion of different types of regulatory requirements. | 1998 | English
In many existing ventilation systems unintentional reentrainment of pollutant, due to improper location of exhaust and air intake, decreases quality of indoor environment.
Building performance evaluation for indoor air quality using occupant contaminant inhalation and attribution to contaminant sources. | 1998 | English
The emissions of building materials like volatile organic compounds and indoor airbornecontaminants such as environmental tobacco smoke expose occupants to hazardowsubstances.
Modern passive stack and ventilated schools - evaluation of ventilation and moisture conditions. | 1998 | English
The aim has been to determine ventilation rates and risk of moisture damage in three modernschools with passive stack ventilation.
The present paper discusses issues related to the potential of natuml ventilation techniques whenapplied to urban environment and in particular to buildings located in canyons.
On the time-dependant efficiency of building ventilation on the indoor air quality in a medium sized urban area in Greece. | 1998 | English
From an air pollution study in a medium-sized, seaside town in Central Greece (Volos) it wasfound that some common air pollutants (CO, NO, NOx, SO,, 0,), whose emissions are connectedto activities and conditions that reveal some characteristics of
The Finnish Society of Indoor Air Quality and Climate has prepared a proposal for the classification of the cleanliness of new ventilation systems and components.
Heat recovery in ventilation systems for office buildings in cold climates is necessary for tworeasons:1. To obtain acceptable indoor thermal comfort by preheating of fresh air,2.
Analytical solutions are derived for calculating natural ventilation flow rates in a single-zone building with two openings when no thermal mass is present.
