Natural ventilation studies were carried out within the frame of PASCOOL EC Research Project. Research on this topic included experimental and modelling…
Ad Hoc Group 4 of Working Group 2 of CEN TC156 (Ventilation) was set up to put forward standardised techniques for estimating ventilation rates in dwellings…
Electric utilities in the Pacific Northwest have spent over $100 million to support energy efficiency improvements in the HUD-code manufactured housing…
Full scale measurements of air flow velocities, temperature, intensity of turbulence and air exchange rate are carried out on two rooms with different types…
Wind towers (scoops situated on the roofs of buildings to catch the wind) have been in use for centuries in the Middle east and Pakistan, to provide…
A Probabilistic model of air change rate in a single family house based on full-scale measurements has been developed. The probability of air change rate…
Since 1985 more than 170 very low energy houses, all of the same type and structure, were built in the Flemish Region, Belgium. Because conduction losses…
The homogeneous emission passive tracer gas technique is described. This technique relies on an even distribution of constant tracer gas emission rate…
System safety of the performance of mechanical ventilation systems can of course be analysed by means of general methods for system safety analysis. Such…
Ventilation by displacement is a type of ventilation where the air flow is thermally driven. By this arrangement one obtains two zones in the room - a lower…
The use of local exhaust is considered to be the most effective way to control pollutant dispersion from intense sources, such as in kitchens, in toilets,…
Although the power law has been broadly accepted in measurement and air infiltration standards, and in many air infiltration calculation methods, the…
The project described in this paper has performed simulations using a multi-zone air flow model (4(COMIS)) of three different passive stack ventilation…
The work presented in this paper is aimed at the definition of tracer gas experimental procedures for measuring the air change rate, the age of air and the…
Train tunnels and subways are an interesting field of ventilation. Trains move air through tunnels at rates of 600 m³/s (over 2 x 10^6 m³ per hour) which is…
Many dwellings with natural or gravity ventilation systems suffer from poor airchange rates. In Sweden, especially houses built in the 1960-ies and 1970-ies…
The first part of the paper will show some aspects of experimental research on air distribution in ventilated rooms. The study has been carried out to get…
A study of the reliability of systems by considering the ability of different systems to maintain a required air flow rate over time is included in a…
Especially in modern buildings with small capacity of humidity storage it is necessary to reduce the humidity in the supply air. Normally this was done by…
The common way to determine air infiltration, exfiltration and interzonal flows from tracer gas measurements in multizoned buildings is to rely upon the…
