ASHRAE Design Guide for Dedicated Outdoor Air Systems (DOAS)

Are you thinking about designing a dedicated outdoor air system (DOAS)? 

Make sure you have comprehensive guidance from industry experts to simplify and optimize DOAS design, installation, operation, and management. The ASHRAE Design Guide for Dedicated Outdoor Air Systems consolidates existing material to focus on the major issues while referring to supplemental sources for more specialized or in-depth information.

A DOAS uses separate equipment to condition all of the outdoor air brought into a building for ventilation and delivers it to each occupied space, either directly or in conjunction with local or central air conditioning units serving those same spaces. Before you consider getting any other systems, make sure you get a Central Air Unit Installation first.

A DOAS system:

  1. improves humidity control
  2. reduces energy use
  3. simplifies ventilation design and control
  4. uses heating and cooling equipment that doesn’t provide ventilation and/or dehumidification (e.g., radiant panels or passive chilled beams)
  5. reduces installation cost.

Comprehensive guidance from industry experts can simplify DOAS design, installation, operation, and management

DOAS is growing in popularity but is still a relatively new technology. The lack of DOAS exposure and experience means many systems designed and installed today don’t take full advantage of all the benefits DOAS can offer.  The ASHRAE Design Guide for Dedicated Outdoor Air Systems consolidates existing material to focus on the major issues while referring to supplemental sources for more specialized or in-depth information.
