Implementation Strategies

General Guidelines

A few basic guidelines apply to all approaches to building with ducts inside:

  • Size equipment capacity to match the envelope requirements.
  • Identify the location of the thermal boundary.
  • Carefully plan how the six-sided air barrier will be installed, who will do the work and what materials will be used. Schedule the trades accordingly.
  • Place the furnace (air handler) in a central location.
  • Keep duct runs short and straight.
  • Minimize equipment and air noise.
  • Locate supply registers on interior walls when possible. Carefully select supply grilles for proper air throw and mixing using ACCA Manual T.
