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

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.
Phaff H J C, de Gids W F
This paper discusses four concepts that have been found useful in improving estimates of ventilation rates in residential buildings. These concepts are improved methods for describing leakage distribution and wind pressures: 1.
Walker I S, Wilson D J
This paper reports on ventilation measurements taken beneath a suspended timber floor of a BRE/DoE energy and environment test house.
Hartless R, White M K
The idea that intend temperatures can be reduced by ventilating the air-space between the ceiling and the roof (the attic) of a house, is widely acknowledged by Civil Engineers and Architects.
Krüger E L, Corbella O D
This paper investigates possible natural ventilation strategies to reduce exposure to environmental tobacco smoke (ETS) in dwellings.
Kolokotroni M, Perera MDAES
Residential ventilation has at least two energy penalties that must be considered when addressing the ventilation levels recommended in ASHRAE Standard 62. Energy is required to heat the fresh outside air used for ventilation.
Stevens D T, O'Connor D
This paper presents a trial of applying a CFD package into an air movement study in an old English church.
Ward I C, Wang F
Measurements of interzone airflow and movement of aerosol particles were carried out in an environmental chamber. SF tracer gas and oil-smoke particles were used for this work.
Cheong K W, Adam N, Riffat S B
Tracer-gas techniques are widely used for measurement of airflow in buildings and their accuracy depends critically on the uniformity of tracerlair mixing.
