Rethinking HVAC for Low-Load Homes

There is not one right heating and/or cooling system that can be universally recommended as each home has different circumstances that must be considered. This is even more so in low-load home. This session will explore the fundamental concepts of selecting and properly distributing conditioned air throughout the home.  The pros and cons of each system type will be considered in some detail, particularly with respect to first cost, energy performance, installation issues, and maintenance needs. Case studies and results from research projects conducted across the country will be presented to support the concepts discussed.

Learning Objectives:

  • Be able to define a “low-load” home and potential HVAC systems that are suitable for these applications.
  • Understand the concepts of point-source or limited distribution for space conditioning and whole-house ventilation. Learn about the potential benefits of dedicated or integrated internal distribution systems.
  • Recognize how comfort is impacted by system selection and occupant behavior in these low-load homes
  • Make informed decisions when selecting home space conditioning systems taking into account project goals, budgets, interactions with other building systems, maintenance, etc.
