***Session 2: Ventilation - Why and How | 3.5 Hours***

With the basics of ducting and airflow understood, the next challenge in mechanical design is effecting ventilation and as we move forward with high energy efficiency we must also begin to examine the importance of air circulation and energy recovery from the exhaust air as fresh air is brought into the home for comfort, safety, and the protection of the building structure and sensitive contents and finishes. Session 2 focuses on various code-conforming ventilation strategies and energy recovery strategies while introducing advanced controls and air circulation options that can also be factored into homes. Heat recovery ventilators, energy recovery ventilators, central recirculating systems and basic supply/exhaust options will be included. An exploration of ventilation strategies that can evolve with the home as energy costs and code requirements evolve will supplement the examination of emerging ventilation technologies that may become code referenced in the future as well as minimalistic approaches for small homes in milder climate locations.
