Application of the tracer gas techniques for the assessment of ventilation indexes in real buildings. | 1996 | English
This paper reports the findings of a pilot field study carried out to investigate the internal and external air pollution levels of two adjacent buildings, one naturally-ventilated and the other air-conditioned in an urban area, to investigate the
The research community as well as the design and construction practice is spending a lot of efforts and investments in developing systems which optimise the energy use for achieving certain specified air flow rates.
This paper presents the special needs and difficulties concerning cooling and ventilation of the SwissMetro high-speed ground transportation system.
The effect of recirculation on the age of air is described.
The LTEE laboratory of Hydro-Quebec, in collaboration with Canada Mortgage and Housing conducted an indoor air quality study involving 30 single family detached houses heated with electric baseboard heaters in the vicinity of Trois Rivières during
AIOLOS: Creation of an educational structure on the use of passive cooling ventilation techniques for buildings. | 1996 | English
AIOLOS is a project partly financed by the European Commission, DG XVII for Energy, within the frame of the ALTENER programme.
Air quality, air flows in buildings, and ventilation are most important topics. Good air quality is however critically dependent also on other things than ventilation, e. g. source strengths, as is well known.
The comparison of the performances of ventilation systems must take into account different issues. For indoor air quality, different kinds of pollutant sources have to be defined.
The present paper presents results from measurements of outdoor airflow rates and air change rates carried out simultaneously with measurements of the indoor concentration of carbon dioxide (CO2 ) .
Comparison of different methods of incorporation of stochastic factors into deterministic models of indoor air quality. | 1996 | English
The paper will discuss problems connected with incorporation of stochastic factors into deterministic models of indoor air quality.
Comparison of indoor levels of radon between workplaces and homes located nearby in different parts of Finland. | 1996 | English
The aim of this study was to compare the radon levels at workplaces and in homes located nearby.
IEA Annex 27: Evaluation and demonstration of domestic ventilation systems. Assessments on noise. | 1996 | English
The acceptance and appreciation of ventilation systems is mainly determined by the perceived indoor air quality, thermal comfort and noise.
A naturally ventilated three level office building has been used to study basic stack ventilation configurations and the interaction between ventilation and the subsequent cooling of the building structure in summer.
How effective is natural ventilation? A study of local mean age of air by modelling and measurement. | 1996 | English
A condition often assumed when designing a naturally ventilated building is where air enters at low level and leaves at high level due to the stack effect.
The role of ventilation in the housing stock is to provide fresh air and to dilute internally-generated pollutants in order to assure adequate indoor air quality.
Design guidelines for ventilation system for pollution control in large, semi-enclosed bus terminus. | 1996 | English
In response to complaints about poor air quality in bus termini, the Hong Kong Government is considering imposing legislative control over ventilation system design and operation of bus termini in Hong Kong.
Adequate ventilation with the "right amount of air, to the right place and at the right time" are important factors for achieving a good indoor climate. Thus it is of prime importance that the ventilation system is working properly.
The study concerns the ventilation of a parallelepiped shape room by means of several systems whose supplying and extracting methods differ, so the different thermic conditions applied to limits.
This study is done by order of a Finnish air cooler manufacturer and it is founded to a master's thesis of the same subject matter. The company produces e.g.
