Variable Air Volume Advancement VAV System Design Manual. The Advanced Variable Air Volume (VAV) System Design Guide (Design Guide) is a valuable new resource for HVAC (Heating, Ventilation, and Air Conditioning) designers. It contains brand new information on fan selection and modeling, as well as the most recent recommendations on VAV airside system design. The Design Guide recommendations include best practises for airside system design, including fans, air handlers, ducts, terminal units, diffusers, and controls, with an emphasis on integrating the air distribution system components.

The following chapters cover critical topics for optimal VAV design and performance: 1) early design issues, 2) zone issues, 3) VAV box selection, 4) duct design, 5) supply air temperature reset, 6) coils and filters, and 7) outdoor air, return air, and exhaust air.

The Advanced VAV System Design Guide (Design Guide) is a resource for HVAC designers that focuses on built-up variable air volume (VAV) systems in multi-story commercial office buildings in California.

The Guidelines are written to assist HVAC designers in creating systems that capture energy savings opportunities while also feeling confident that system performance will meet client expectations. This is a best practises manual based on experience designing and commissioning mechanical and control systems in commercial buildings, as well as research from five case study projects.

The recommendations cover airside system design, including fans, air handlers, ducts, terminal units, diffusers, and their controls, with an emphasis on integrating the air distribution system components.

Key topics critical to optimal VAV design and performance are:
