Event Description

Improved health and cognitive performance. Easier Title 24 compliance. Utility bill savings. These are the reasons to consider incorporating Heat Recovery Ventilators & Energy Recovery Ventilators (collectively Recovery Ventilators or RVs) into your next high-performance home project.

The instructors are a high-performance home contractor and energy consultant who together have specified and installed hundreds of RVs. They will draw on these experiences and data gathered from these units to better understand these mechanical ventilation systems and their benefits. They will cover the details of ducting to the outside for inlet and exhaust air and distributing the supply and exhaust throughout homes. Balancing airflow rates and maintenance requirements will also be covered.

3C-REN will also go over new 2025 energy code requirements for balanced ventilation and heat recovery in multifamily dwelling units, how to add an RV to a Title 24 compliance energy model and the change in energy use and compliance metrics that result. 3C-REN will present various configurations of RVs, including through-the-wall paired units, packaged HRVs and packaged ERVs, and various ducting options.

Learning Objectives -

• Understand the basics of how Recovery Ventilators (RVs) work to improve indoor air quality in homes and reduce heating and cooling energy use
• Learn the 2025 energy code requirements for mechanical ventilation in single-family and multifamily buildings and how RVs impact Title 24 compliance metrics
• Model a case study home and multifamily building using RVs and examine the energy use and compliance scores in various configurations
• Hear best practices for specifying and installing RVs
