ASHRAE's Laboratory Design Guide has been organized and developed to provide owners, designers, contractors, and operators with key information on the essential requirements for achieving high quality laboratory facilities. This design guide can be used for the design, troubleshooting, and operation of laboratory facilities or as a comprehensive reference. The design guide progresses from project inception through operations and includes chapters on: Laboratory Planning, Design Process, Exhaust Hoods, Primary Air Systems, Process Cooling, Air Treatment, Exhaust Stack Design, Energy Recovery, Controls, Airflow Patterns and Air Balance, Operation and Maintenance, Laboratory Commissioning Process, HVAC System Economics, and, finally, Microbiological and Biomedical Laboratories.
