ASHRAE Design Guides

Share This

Good design requires addressing and balancing a variety of competing goals. In addition to improving the built environment through its technical standards and guidelines, ASHRAE also offers specialized design guides as readable, relatable and easy to implement companion texts for a variety of topics commonly faced by consulting engineers, designers and facility managers.

Real-world guidance from real experts—ASHRAE Design Guides

For Integrating Building Systems


ASHRAE Greenguide: Design, Construction, and Operation of Sustainable Buildings, 5th Edition

This new edition of ASHRAE GreenGuide is an easy-to-use reference with information on almost any subject that should be considered in green-building design. GreenTips highlight techniques, processes, measures, or special systems in a concise format, and references and resources mentioned are listed at the end of each chapter for easy access.


For Air Terminal Units


ASHRAE Design Guide for Air Terminal Units: Selection, Application, Control, and Commissioning

ASHRAE Design Guide for Air Terminal Units provides detailed guidance for selection, application, control, and commissioning of a common element in all-air HVAC systems--the air terminal unit (ATU). It was written with a view toward current codes, standards, and design practices and is intended to aid design engineers in sizing units while maximizing occupant comfort and energy efficiency.


For Tall Buildings


ASHRAE Design Guide for Tall, Supertall, and Megatall Building Systems 2nd Ed.

Expanded since ASHRAE's previous guide on the topic in 2004, this new design guide covers not only tall buildings (taller than 300 ft [91m]) but now also addresses supertall (taller than 984 ft [300 m]) and megatall (taller than 1968 ft [600 m]) buildings, with a broadened scope and updated content that reflects current standards and industry practices.


For Laboratories


ASHRAE Laboratory Design Guide: Planning and Operation of Laboratory HVAC Systems, 2nd ed.

This second edition of ASHRAE Laboratory Design Guide is a comprehensive reference manual for the planning, design, and operation of laboratories. It gives engineers, owners, and system operators the design and control strategies they need to reduce the laboratory's energy footprint while ensuring safety, providing good comfort and indoor air quality, and protecting the integrity of laboratory experiments.




ASHRAE Design Guide for Dedicated Outdoor Air Systems

Dedicated outdoor air systems (DOAS) are growing in popularity, but are still a relatively new technology. ASHRAE Design Guide for Dedicated Outdoor Air Systems offers comprehensive guidance from industry experts to simplify DOAS design, installation, operation, and management. Guided by the information in this book, HVAC system designers will be able to optimally incorporate DOASs into their projects.

Available in English or Spanish


For Geothermal Systems


Geothermal Heating and Cooling: Design of Ground-Source Heat Pump Systems

Geothermal Heating and Cooling is a complete revision of Ground-Source Heat Pumps: Design of Geothermal Systems for Commercial and Institutional Buildings, which is recognized as the primary reference for nonresidential ground-source heat pump (GSHP) installations. This new work takes advantage of the many lessons learned since the time of the original publication, when GSHPs were primarily residential applications.


For Cleanrooms


ASHRAE Design Guide for Cleanrooms: Fundamentals, Systems, and Performance

This design guide is divided into four parts: Cleanroom Fundamentals; Cleanroom Design and Environmental Control Systems; Cleanroom Testing, Certification, Commissioning, and Qualification; and Cleanroom Design in Select Industries, and is written to be immidiately applicable by designers, builders, owners, and operators of cleanrooms and advance HVAC engineering practices.


For Natural Ventilation


ASHRAE Design Guide for Natural Ventilation

ASHRAE Design Guide for Natural Ventilation assists engineers, architects, building owners, facilities personnel, and building design professionals in exploring the feasibility of natural ventilation for their projects during the early phases of design as a way to encourage designing energy-efficient naturally ventilated buildings.
