This book was released on 1988 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four different but complementary methods were used to obtain detailed information on air infiltration and interzonal airflow rates in two bilevel research houses: the tracer gas dilution method, single tracer constant concentration, passive perfluorocarbon tracers (constant release), and constant release of multiple halocarbon tracers with real-time analysis. The study included measurements of seasonal variations and differences between the houses, one of which was retrofitted in a previous EPRI study to reduce the air leakage area.

This book was released on 1990 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four different but complementary methods--the tracer gas dilution method, single-tracer constant concentration, passive perfluorocarbon tracers (constant release), and constant release of multiple halocarbon tracers with semicontinuous analysis--were used to obtain detailed information on air exchange and interzonal airflow rates in the two GEOMET bilevel research houses. The four methods yielded comparable measurements of single-zone (whole-house) air exchange rates. Constant concentration tracer gas, perfluorocarbon tracer, and multiple halocarbon tracer measurements yielded comparable measurements of upstairs and downstairs air infiltration rates; downstairs infiltration rates were as much as seven times higher than upstairs. The constant-concentration method also provided detailed information on room-specific infiltration rates. Perfluorocarbon tracer (PFT) measurements of airflow rates between conditioned zones, the attic, and garage demonstrated the effectiveness of house-tightening retrofit procedures to reduce airflows to the unconditioned airspaces. Perfluorocarbon and halocarbon measurements of week-long, time-averaged interzonal airflow rates were comparable, but the halocarbon system showed that hourly interzonal airflow rates could be as much as an order of magnitude higher than the week-long average.

Download or read book Design and Protocol for Monitoring Indoor Air Quality written by Niren Laxmichand Nagda and published by ASTM International. This book was released on 1989 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is derived from a symposium prompted by the growing concern for air quality in homes, offices and schools, and the need for better design of investigations about indoor air quality problems and solutions. Numerous chemical and physical factors influence the indoor concentrations of contaminants. The multiplicity of these factors makes the investigation design process complex. So, well-conceived designs and protocols form a crucial starting point for successful measurement programs. "Design" of a study relates to developing a general strategy or approach ; "protocols" refers to specific procedures to be followed in conducting a study. This document aims to provide information on designs and protocols used in different types of indoor air quality monitoring studies and to supply learning opportunities through shared experience

Download or read book Building Ventilation written by Mat Santamouris and published by Routledge. This book was released on 2006-06-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
