As a result of this webinar, you will be able to:

  • Describe the importance of residential ventilation and promote its benefits.
  • Select appropriate ventilation equipment.
  • Apply various control strategies including intermittent operation.
  • Explain the impacts of quality installation techniques and materials.
  • Identify inexpensive methods to measure CFM.
  • Understand proper ventilation system documentation.
  • Calculate ASHRAE 62.2 whole building and local exhaust fan CFM.

Who should watch?

HVAC apprentices, installers and service technicians; building performance consultants; weatherization personnel; residential builders and remodelers; designers and architects; code officials; and anyone interested in quality residential ventilation systems.

Tight, properly ventilated homes are a priority when it comes to high performance building. Although it is not adopted everywhere, the ASHRAE 62.2 Standard mandates and scrutinizes effective mechanical ventilation. This standard has been adopted by the U.S. Department of Energy Weatherization Assistance Program and the Building Performance Institute. Could it eventually be required in the communities you serve? Be prepared.

Like everything else in building science, there's a lot more to residential ventilation than simply opening the windows. As houses get tighter, the need for mechanical ventilation to ensure indoor air quality increases and the interaction with other air-hungry equipment, such as combustion devices, becomes more critical. These converging issues have influenced standards, which emphasize effective ventilation systems in both new and existing homes.

With a multitude of parts, the ASHRAE 62.2 Standard addresses sizing and installed system performance. Review ventilation system fundamentals, design, selection, operating costs and testing to comply with the latest version of the ASHRAE 62.2 Standard. Learn best practices to document installation procedures and performance results. Understand infiltration rates and conditions in existing homes in order to properly size ventilation systems.

During this webinar, participants will calculate the whole building ventilation rate for a new home, the adjusted whole building ventilation rate for an existing home, the infiltration credit and the effective length of a duct run.
