Hot Humid Climates Cover
The ASHRAE Guide for Buildings in Hot and Humid Climates, Second Edition [purchase]

Harriman, Lewis G. and Joseph W. Lstiburek
2009 book (or downloadable PDF), 316 pages, color

The expanded second edition of The ASHRAE Guide for Buildings in Hot and Humid Climates triples the size of this popular reference, adding information on building enclosures, dehumidification, sustainability, mold avoidance, energy reduction, and much more—all tightly focused on the needs of owners, architects, and engineers who build and manage buildings in hot and humid climates. The book includes six chapters that discuss critical crosscutting issues for architecture, engineering, and building management along with eleven chapters of detailed and practical solutions to everyday problems in each area. This expanded second edition provides a richly illustrated summary of the state of the art in building science, moisture management, and techniques for reducing energy consumption in hot and humid climates, all based on real-world field experience as well as on recent ASHRAE research. The expanded second edition is written and illustrated by Lew Harriman, the lead author of ASHRAE’s well-known Humidity Control Design Guide, and by Joe Lstiburek, ASHRAE Fellow and the author of the irreverent and popular Building Science column in the ASHRAE Journal.


Mold DVD Cover
Mold in the Building Environment [purchase]

an ASHRAE satellite broadcast DVD (recorded on April 13, 2005)

Concerns about mold in the building environment are no longer limited to just humid environments or North America. Mold is now a global concern for facility managers, building owners/operators, designers, contractors, and building occupants. This DVD provides information on how to properly control moisture and humidity conditions in order to minimize mold. Sponsored by ASHRAE’s Chapter Technology Transfer Committee (CTTC), this broadcast/webcast was recorded on April 13, 2005 at the WETA public television studio in Washington, DC.



Humidity Control Design Guide for Commercial and Institutional Buildings [purchase]
Harriman, Lewis G., G.W. Brundett, and Reinhold Kittler
2002 hardcover book, 31 chapters, 512 pages, color

This four-color, hardback book is an easy-to-read, user-friendly manual aimed at HVAC designers concerned with humidity control. It helps to define the purpose of a humidity control project, and provides information on the effects of humidity on mold, mildew, bacteria, viruses and overall human health and comfort. The text also discusses how humidity control equipment works and the importance of managing air pressure in a building. Schools, office buildings, nursing homes and laboratories are discussed in depth along with other types of buildings. The book provides checklists to help architects, owners, contractors and building and HVAC system designers get the job done quickly and accurately.
