1 Year Later: What Builders Can Learn From the Panasonic OASYS Home

Learn more about the Panasonic OASYS system: https://oasys.na.panasonic.com Follow Panasonic IAQ on Instagram:   / panasoniciaq   One year after completion, the Panasonic OASYS concept home has been fully lived in, monitored, tested, and analyzed—and the results are in. In this episode of The Your Project Shepherd Podcast, Curtis Lawson is joined by Ken Nelson, Group Sales Manager for Panasonic IAQ, to break down what builders can actually learn from a full year of real-world performance data from the OASYS home in Houston, Texas. This is not a showroom demo or a lab test. This home has experienced occupancy, vacancy, extreme heat, high humidity, system adjustments, and even intentional stress-testing—all while collecting temperature, humidity, and air quality data throughout the house. Key builder takeaways from this conversation include: 1. Why continuous air movement outperforms traditional HVAC cycling 2. How OASYS achieved consistent temperatures within 1–2 degrees room to room 3. What the data revealed about moisture management in a tight envelope 4. The real-world performance of ERVs in hot, humid climates 5. Why small “cost savings” during construction can lead to major warranty risks 6. What surprised Panasonic most after a full year of operation If you’re a builder thinking about tighter envelopes, indoor air quality, moisture risk, or long-term durability—not just first-cost decisions—this 1-year retrospective offers practical insights you can apply to your own projects.
