Optimize light commercial HVAC designs with VRF and packaged rooftops


Beginning Jan. 1, 2023, The U.S. Department of Energy (DOE) is increasing minimum efficiencies for residential and commercial HVAC equipment. Commercial HVAC equipment larger than 65 kBTU increased an average of 15% above current minimum integrated energy efficiency ratio (IEER) ratings. For specifying engineers, this means new product offerings and technology in light commercial HVAC equipment.

Looking into the future, variable refrigerant flow (VRF) systems continue to increase as a popular choice providing a flexible, versatile solution that is ideal for a wide range of structures and industries. This will help mechanical engineers understand light commercial rooftop equipment changes and how VRF technology can help build better air in building design.

Learning objectives:

  • Understand the U.S. Department of Energy 2023 commercial requirement highlights.
  • Review technologies to meet new regulations.
  • Learn the advantages of technology to design comfortable air in buildings.
  • Review VRF technology.
  • Explore the advantages of designing with VRF equipment.
