About the program

Commercial building architects and engineers are moving to provide better energy efficiency in the buildings they design and construct.  The need to provide better ventilation strategies for healthy and comfortable indoor spaces and still meet energy efficiency goals requires a better   understanding of the design and installation of ventilation systems. The result can be dramatically better occupant health and productivity, as well as dramatically reduced energy use to provide outside air.

This workshop dives deep into energy recovery ventilation systems, removing the mystery of how these systems work. Since ventilation systems often last as long as the building, getting it right during design and installation will save energy for decades to come.

Participants will learn:

  • What Are High-Performance Buildings and High-Performance Ventilation
  • Why Efficiency Matters: HRVs, ERVs, Cross-Flow, Counter Flow, Wheels
  • Best Practices for a Range of Building Types
  • Ventilation Standards: Where We Are and Where We Are Going
  • All About Controls: Constant Air Volume (CAV), Demand Control Ventilation (DCV), Variable Air Volume (VAV), Flow Options, and Building Control Integration
  • Retrofit Opportunities Utilizing Dedicated Outdoor Air Systems (DOAs) and High Performance Heating & Cooling

Who Should Attend?

Architects: The design of ventilation systems starts at the beginning of the design process, and architects play a vital role in enabling good design and application of these principles.  Engineers: Much of this technology and equipment is cutting edge to many engineers, and this workshop dives in to the impact that ventilation done right can have on the entire HVAC system.  Contractors: The best design is only as good as the installation that follows. Understanding what makes a ventilation system efficient is critical to installing it correctly.  Energy Efficiency Professionals: Whether you work with new-build projects looking for energy efficiency, or with retrofit programs from utilities or energy efficiency organizations, this workshop is for you.
