Resources for Commercial and Industrial Air Systems Design

Air system performance is greatly influenced by how the system is designed and how equipment is sized, selected, installed, controlled, and operated within the system. These factors have an influence an order of magnitude greater than the marginal gains possible when attempting to increase the efficiency of any one component. With this in mind, AMCA advocates lifecycle best practices for air systems.
This section of the AMCA website provides links to information and resources for lifecycle performance of air systems and equipment. It has the following sections:

Technical Articles: Fan Efficiency Codes, Standards, &Regulation

Note:In 2011, DOE's "Office of Industrial Technologies" was renamed to "Advanced Manufacturing Office"

Other Engineering Resources
  • Advanced Variable Air Volume System Design Guide, University of California & California State University Project Teams, 2003. Note: This manual is written for HVAC designers and focuses on built-up variable air volume (VAV) systems in multi-story commercial office buildings in California.
  • Commercial Energy Services Network (COMNET) Modeling Guidelines and Procedures, Fan Systems, Baseline Building Fan System Summary. Note: COMNET energy efficiency calculation process serves multiple purposes, including the following:
    • Establishing eligibility for federal tax deductions per Section 179D of the Internal Revenue Service (IRS) code;
    • Calculating percent savings for point eligibility related to green building rating systems; and
    • Estimating annual energy use for a building in the design phase for the purpose of energy labels.

From 2013 I2SLInternational Institute for Sustainable Laboratories Conference, Minneapolis

From 2012 ASHRAE Annual Meeting, San Antonio:

From AMCASeminar at 2012 AHRExpo in Chicago:
  • Michael Brendel, PhD, Lau Fan, gave a presentation on how fan efficiency grades, as defined by AMCAStandard 205, Energy Classification for Fans, are linked to the fan brake-horsepower requirements in ANSI/ASHRAE/IES Standard 90.1-2010, Energy Standard for Buildings Except Low-Rise Residential Buildings. Click here for Michael Brendel's PowerPoint slides (1-MB PDF).
  • Steve Wiggins, PE, LEEDAP, from Newcomb & Boyd Engineering, then described how commissioning newly installed systems and revisiting the systems after a period of time (or setting up monitoring-based commissioning systems) will reduce wasted energy consumption and costs. Click here for Steve Wiggins PowerPoint slides (1-MB PDF).
  • John Reints, PE, (consulting engineer) and Gene Smithart, PE, Trane, closed the session with an in-depth presentation on high-velocity static-regain duct systems, which reduce first costs and operating costs. Click here for the Smithart/Reints PowerPoint slides (6-MB PDF).
