Tracer-gas techniques are widely used for measurement of airflow in buildings and their accuracy depends critically on the uniformity of tracerlair mixing.
Riffat S B, Shao L
The main goals for this design tool are: - A powerful, but simple to use, technical and economic tool for selecting a ventilation plant. - Guide and control the consultants in accordance with the owner's economic preferences.
Wernstedt G
Simulation is proving more and more important in building physics. Programs of different levels of complexity are today available for researchers and designers to model and plan buildings.
Furbringer J-M
This paper is concerned with measurement of air and aerosol particle exchange efficiency in a single zone chamber. Aerosol particles and tracer gases were injected into the chamber and their concentrations were monitored as a funtion of time.
Adam N, Cheong K W, Riffat S B, Shao L
The monitoring of the performance of domestic ventilation systems is quite a complex exercise.
Edwards R E, Irwin C
One important aim for the development of new air conditioning systems is the reduction of the total energy consumption.
Steimle F, Mengede B, Schiefelbein K
The ventilation of a Swedish single family house is investigated by means of tracer gas and pressurization techniques.
Hedin B
The purpose of this study was to test an Indoor Air Quality model on a variety of Canadian homes, and use this model to determine the optimal ventilation levels necessary to provide appropriate comfort levels.
Hamlin T, Pushka W
A study has been undertaken to (1) evaluate airtightness in recent construction dwellings in New York State, (2) evaluate the effectiveness of various strategies in providing adequate ventilation, and (3) study the use of various ventilation optio
Matson N E, Feustel H E, Warner J L, Talbott J
This paper presents a measurement technique to perform quantitative visualization of room air flows.
Scholzen F, Moser A, Suter P
Occupant response in a good indicator of the effectiveness of a ventilation system. In a one-year study in the province of Quebec region, 20 public buildings were studied.
Donnini G, Nguyen V H, Molina J
Workers in 'white collar' jobs continue to complain about air-quality' problems.
Bassett M R, Isaacs N
Building airtightness data are essential for design and model evaluation. An attempt has been made with the Numerical Database to compile data appropriate toinfiltration and ventilation studies.
Orme M S
The work was concerned with measuring natural convection through a large horizontal opening of different sizes and shapes located between two rooms in a building.
Kohal J S, Riffat S B, Shao L
As a result of the "Sick Building Syndrome" (SBS) the confidence of operators of office buildings into HVAC technologies has suffered a considerable drop.
Steimle F, Roeben J
In many design cases, energy as well as occupant comfort are the relevant criteria which are studied using computer simulation programs. Comfort evaluations cover air quality, thermal, visual and acoustical comfort.
Dorer V, Weber A
A series of laboratory experiments are described which investigated the effect of surface roughness on the air flow characteristics of simple, straight-through, no-bend cracks with smooth and rough internal surfaces.
Kula H-G, Sharples S
Indoor air quality, comfort and energy use in buildings are largely dependent on the performance of HVAC systems. However, the pressure loss factors available to the designer show large discrepancies depending on the source of the data.
Riffat S B, Shao L, Woods A G
The Air Lock Floor and the Pressure Ring are two effective measures for control of air flow directions between rooms or zones in buildings. They create a pressure hierarchy that controls spread of pollutants.
