Book Description
A method has been developed to measure real-time airflow in multifamily buildings. This method uses a multi-tracer measurement system (MTMS) and simultaneous measurements of pressure, temperature, and environmental conditions. These measurements are evaluated along with the results of blower door and flowhood fan tests to develop a complete picture of the airflow patterns in multifamily buildings due to temperature differences, wind, and mechanical ventilation.

Book Description
The balanced fan depressurization method has been modified for application to high-rise apartment buildings in order to measure the overall air leakage and the wall air leakage of an apartment unit simultaneously. The method requires the use of two sets of fan pressurization apparatus. One is installed at the door of an apartment unit for measuring the air leakage rate of the exterior wall, and a much larger apparatus is installed at an exterior door of the building for measuring the overall air leakage rate. The pressures between the test unit and the adjacent units are balanced to minimize the air leakage through the party walls by adjusting the airflow of the larger apparatus and the door opening of the adjacent apartments. The method was successfully applied to two high-rise apartment towers before and after they were retrofitted to improve airtightness of the envelope. In addition, the tracer gas decay method was applied to the same buildings to obtain the infiltration rates of selected apartment units.

Book Description
A ventilation field measurement study was conducted during the 1986/1987 and 1987/1988 heating seasons in 39 energy-efficient multifamily dwelling units. Four buildings, two in eastern Washington and two in western Washington, were involved in the study. The purpose of the study was to determine the total and baseline (natural) air exchange rates in units representing energy-efficient construction in the multifamily sector of the Pacific Northwest. This information will be used to aid in the development of future construction codes and standards. The air exchange rate was measured a multiple perfluorocarbon tracer (PFT) technique. Most measurements were taken over a 2- to 4-week period, with a few measurements taken over a period of one to three consecutive months. The PFT technique allows one to determine the fresh air flow into any unit within a building as well as the air flow between adjacent units. In addition, the volumetric air flow and usage of the mechanical ventilation system installed in the units were measured. Temperature, weather, structure, and occupancy data were also collected. 12 refs., 19 figs., 14 tabs.

Book Description
Energy efficiency in buildings requires, among other things, that ventilation be appropriately dimensioned: too much ventilation wastes energy, and insufficient ventilation leads to poor indoor air quality and low comfort.Studies have shown that ventilation systems seldom function according to their commissioned design. They have also shown that airflow measurement results are essential in improving a ventilation system. This key handbook explains why ventilation in buildings should be measured and describes how to measure it, giving applied examples for each measurement method.The book will help building physicists and ventilation engineers to properly commission ventilation systems and appropriately diagnose ventilation problems throughout the life of a building. Drawing on over 20 years of experience and the results of recent international research projects, this is the definitive guide to diagnosing airflow patterns within buildings.

Book Description
Ensuring optimum ventilation performance is a vital part of building design. Prepared by recognized experts from Europe and the US, and published in association with the International Energy Agency's Air Infiltration and Ventilation Centre (AIVC), this authoritative work provides organized, classified and evaluated information on advances in the key areas of building ventilation, relevant to all building types. Complexities in airflow behaviour, climatic influences, occupancy patterns and pollutant emission characteristics make selecting the most appropriate ventilation strategy especially difficult. Recognizing such complexities, the editors bring together expertise on each key issue. From components to computer tools, this book offers detailed coverage on design, analysis and performance, and is an important and comprehensive publication in this field. Building Ventilation will be an invaluable reference for professionals in the building services industry, architects, researchers (including postgraduate students) studying building service engineering and HVAC, and anyone with a role in energy-efficient building design.
