‘This book is unique. It cleverly demonstrates the appropriate techniques to measure the ventilation and energy efficiency of naturally and mechanically ventilated buildings. It also offers the background necessary for this investigation, covering procedures to improve its performance and the reporting of results. This is a valuable single-source reference not only for academics but for practitioners: a practical, useful source of knowledge.’
PROFESSOR FARIBORZ HAGHIGHAT, Department of Building, Civil and Environmental Engineering, Concordia University, Canada

‘A book we need: an excellent overview of the state of the art of measurement techniques applied to airflows in buildings and to ventilation systems, written by a real expert.’
PROFESSOR FRANCIS ALLARD, University of La Rochelle, France

‘This book covers all of the important technical information for ventilation measurement. It is very useful for not only HVAC engineers but also researchers and university students.’
HIROSHI YOSHINO, Professor, Department of Architecture and Building Science, Tohoku University, Japan

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.
