Passive House, HERS Ratings, Blower Door Testing & Why Verification Matters -Season 2, Epi 10

Send us Fan MailWhat does it actually mean for a building to perform?In this episode of the HVAC ADHD™ Vodcast, Jeremy Begley sits down with Neil Goldman, owner of Less Energy, HERS Rater, Passive House consultant, and Philadelphia's first certified blower door Special Inspector, for a deep dive into testing, verification, and high-performance buildings.A building can meet a standard. It can earn a certification. It can look great on paper.But did anyone verify that it actually performs?Neil and Jeremy explore the relationship between the building envelope and the HVAC system—and why testing becomes even more important as buildings get tighter, mechanical loads get smaller, and ventilation becomes more intentional.We dive into:• Passive House principles and high-performance construction• HERS Ratings and what they tell us about building performance• Blower door testing and airtightness verification• Large-building blower door testing• Energy Star and third-party verification• ERVs, ventilation, and indoor air quality• HVAC sizing for tighter, lower-load buildings• Commissioning and verifying mechanical system performance• Why the building envelope and HVAC system can't be treated separately• The difference between meeting a certification and proving real-world performanceThis episode gets into one of the most important principles in building performance:👉 Don't assume the envelope performs. Test it.👉 Don't assume the HVAC performs. Commission it.👉 Don't assume the ventilation works. Verify it.Whether you're an HVAC contractor, HERS Rater, energy auditor, building performance professional, HVAC designer, commissioning provider, or Passive House professional, this conversation offers a practical look at why measurement and verification have to be part of the process.🔗 Neil Goldman's LinksLes NRG:https://www.blowerdoortestphilly.com/aboutLinkedIn:https://www.linkedin.com/in/neil-goldman-2b10a935Instagram:https://www.instagram.com/les.nrg/🎥 WATCHYouTube:https://youtu.be/IxRBubAL5As📲 Follow HVAC ADHD™YouTube:https://zurl.co/wpJHEInstagram:https://zurl.co/zrhQWFacebook:https://zurl.co/mCS5a#HVACADHD #HVACADHDVodcast #JeremyBegley #NeilGoldman #PassiveHouse #HERS #HERSRater #BlowerDoor #BlowerDoorTesting #Airtightness #EnergyStar #BuildingScience #BuildingPerformance #HomePerformance #HVACDesign #HVACPerformance #Commissioning #Ventilation #ERV #IndoorAirQuality #BuildingEnvelope #EnergyEfficiency #HVACTech #HVACTraining #HVACIndustry #HighPerformanceBuilding
