"As homes get tighter, ventilation isn't optional—it's essential."

— Patrick Nielsen
 

In this episode of RESTalk, host Bill Spohn sits down with Patrick Nielsen, Global Technical Products Manager at Broan-NuTone, to discuss the evolving world of home ventilation. With over two decades of experience, Patrick walks us through the major drivers shaping residential ventilation practices today—from tighter building envelopes to the growing emphasis on indoor air quality and energy efficiency.

Patrick explains the importance of dwelling unit ventilation (DUV), spot vs. whole-house strategies, and the increasing role of energy recovery ventilators (ERVs) as builders and raters seek practical ways to meet stringent codes and achieve better HERS scores. He also touches on upcoming developments like capture efficiency standards for range hoods, automated balancing features in modern ERVs, and the implications of makeup air requirements. Whether you’re a builder, rater, or HVAC pro, this episode is packed with actionable insights for navigating the ventilation challenges in today’s high-performance homes.
