Available in PDF, EPUB and Kindle. Book excerpt: The ASTM Method for Determining Air Leakage Rates by Fan Pressurization Test (E 799-87) measures the airtightness of building envelopes using fan pressurization. Uncertainty is introduced in the process from the uncertainty of the airflow and pressure measurements as well as from nonlinearities in the system to be measured. This paper analyzes the precision and bias associated with making a measurement using E 779 in typical field situations. Model specification (or modelization) errors may also contribute significantly to the overall uncertainty in the estimates of the 4 Pa leakage; the sources and sizes of these modelization errors interact with the instrumentation errors in making a fan pressurization test. Insufficient field data exist to fully include the effects of modelization and other low-pressure phenomena, but the current standard can nevertheless by improved by tightening the instrumentations and procedural specifications and by judicious choice of pressure measurement stations.

This book was released on 1995 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: ASTM has recently standardized a methodology for measuring the leakage of residential air distribution systems to unconditioned zones [ASTM Test Method for Determining the External Air Leakage of Air Distribution Systems by Fan Pressurization (E 1554-93)]. The standard includes two alternative leakage measurement techniques. One technique requires only a blower door, whereas the second technique requires a flow-capture hood as well as a blower door. This paper reports on the results of field measurements in 30 houses using both measurement techniques, and analyzes the relative strengths and weaknesses of the two techniques. The repeatability of each of the techniques, as well as the comparability of the results from the two techniques, is examined. A key issue addressed is the importance of duct pressure measurements in each of the two techniques. Analyses show that the leakage measured with the blower-door-only technique would have been negatively biased by 30% to 50% if the duct pressure had not been incorporated into the measurements and analyses as specified in the standard. Similarly, it is shown that supply leakage measurements with the flow-capture-hood technique would have been negatively biased by 33% if the envelope pressure differential had been used instead of the duct pressure differential.

Available in PDF, EPUB and Kindle. Book excerpt: People live in indoor environment about 90% of lifetime and an adult inhales about 15 kg air each day, over 75% of the human body’s daily mass intake (air, food, water). Therefore, indoor air quality (IAQ) is very important to human health. This book provides the basic knowledge of IAQ and highlights the research achievements in the past two decades. It covers the following 12 sections: introduction, indoor air chemicals, indoor air particles, measurement and evaluation, source/sink characteristics, indoor chemistry, human exposure to indoor pollutants, health effects and health risk assessment, IAQ and cognitive performance, standards and guidelines, IAQ control, and air quality in various indoor environments. It provides a combination of an introduction to various aspects on IAQ studies, the current state-of-knowledge, various advances and the perspective of IAQ studies. It will be very helpful for the researchers and technicians in the IAQ and the related fields. It is also useful for experts in other fields and general readers who want to obtain a basic understanding of and research advances in the field of IAQ. A group of experts in IAQ research have been recruited to write the chapters. Their research interests and experience cover the scope of the book. In addition, some experienced experts in IAQ field have been invited as advisors or reviewers to give their comments, suggestions and revisions on the handbook framework and the chapter details. Their contribution guarantees the quality of the book. We are very grateful to them. Last but not least, we express our heartfelt thanks to Prof. Spengler, Harvard University, for writing the foreword of the current Handbook of Indoor Air Quality both as a pioneer scientist who contributed greatly to indoor air science and as an Editor-in-chief of Handbook of Indoor Air Quality 2001, 1st ed. New York: McGraw-Hill. In addition to hard copies, the book is also published online and will be updated by the authors as needed to keep it aligned with current knowledge. These salient features can make the handbook fresh with the research development.

Book excerpt: To comply with the International Energy Code, most states now require duct testing for both new construction and retrofit. Duct leakage testing provides an in-depth understanding of duct leakage testing procedures, methods of expressing results, and terminology. Building Science is the study of a building's interaction between the structure and its components. A structure's occupants, mechanical systems, and the surrounding outdoor environment all play a role in the performance of a building. Duct Leakage Testing covers: * Duct leakage testing methods or total leakage. * Leakage to the outside using a duct pressurization tester. * Modified blower door subtraction methods.
