475 Presentation: Decentralized High Efficiency Ventilation

Decentralized High Efficiency Ventilation is a high performance alternative to centralized, ducted systems for whole house ventilation. As buildings are being renovated or built airtight to meet greater demands of low-energy, high-comfort, toward Passive House and similar buildings – they need to be properly ventilated. Often centralized systems are not ideal given equipment and ductwork space requirements.  With a decentralized system, there is no ductwork and the units are mounted within the exterior wall assemblies – giving designers and building owners new options for achieving high-performance ventilation. This course examines the component options and design parameters for such a system.


Learning objectives:  Upon completion participants will be able to:

  1. describe the difference between centralized and decentralized ventilation systems.
  2. describe essential qualities of high performance, high-efficiency heat recovery ventilation systems.
  3. calculate the decentralized system sizing and layout.
  4. describe essential installation parameters.

Who Should Attend:

  • Architects
  • Mechanical Engineers
  • Builders
  • Building Science Consultants
