ASHRAE guidebook on hot and humid climates (April 2009)

The second edition of the ASHRAE Guide for Buildings in Hot and Humid Climates offers comments and suggestions about keeping heat and humidity out of buildings in climates where those elements are a factor. The book includes four new chapters to guide architectural design toward reduced energy consumption, reduced mold risk and lower-cost mechanical systems. The HVAC&R design section has also been expanded. Six new chapters help system designers quantify and reduce cooling and dehumidification loads, design more economical ventilation systems and save more than 25 percent of annual HVAC&R energy through low-cost sealing of air distribution components. Chapter summaries allow building professionals to quickly understand the big picture issues and the logic behind suggested best practices for hot and humid climates. The book also provides specific, actionable suggestions for implementing ASHRAE standards for comfort, ventilation and energy efficiency in parts of the world where high heat and humidity can occur at any time of the year.
