A High-performance HVAC Approach for Better Indoor Air Quality, Energy Savings and Resilience

NOVEMBER 17, 2022 | 8:00 AM - 12:00 PM
  • This event has passed.

This four-hour live, interactive webinar will review a wide range of ventilation topics including system design, specification and installation for high-performance, small- to medium commercial buildings. Attendees will learn about advances in dedicated outside air systems (DOAS) and the pairing of HRVs/ERVs. Participants will also learn about very high efficiency heating and cooling systems and optimized system design. This HVAC design approach has yielded significant energy and cost savings in buildings across the Northwest while providing better indoor air quality and improved occupant comfort.

Through this course, attendees will learn to:

  • Identify the features and attributes of high-performance buildings, including common mistakes and drawbacks to “value engineering” HVAC systems
  • Differentiate between HRV and ERV operation and design, as well as metrics of efficiency
  • Communicate to clients the important role ventilation plays in health and indoor air quality (IAQ) based on studies and emerging requirements and standards for IAQ
  • Understand and differentiate between various current and future ventilation requirements and standards, including ASHRAE 62.1, IMC and PHI
  • Identify retrofit opportunities using high-performance HRVs/ERVs and heating and cooling systems
  • Properly design and install high-performance HVAC systems
