Building HVAC Science

"Astronomy's much more fun when you're not an astronomer." Brian May COVID-19 has impacted the way people interact for many months. Especially the way people interact with each other in spaces outside their homes. What do the air quality scientists have to say about the management of indoor air? What kind of measurements are significant and important? Will this pandemic impact the way we do things in HVAC after it subsides? Steve Pascuzzo, manager of testo's commercial division, joins us to discuss indoor air quality metrics, with a keen focus on managing the return to schools after COVID-19. Steve also shares with us his background, career path and his keen intertest in astrophotography and shares with us the 7 unusual features of Oumuamua - the first known interstellar object detected passing through our Solar System. Here is the link to the ASHRAE guideline for reopening schools and universities as mentioned in the podcast: https://www.ashrae.org/technical-resources/reopening-of-schools-and-universities To learn more about testo products visit: www.TruTechTools.com/testo This episode was recorded in January 2021.

"Vision is the art of seeing what is invisible to others." Jonathan Swift Listeners to this podcast know, it is often very hard to explain what it is we do. When I try to explain this, people's' eyes and ears glaze over as I get into the technical descriptions of the invisible elements that make a home more comfortable, safer, healthier and energy efficient. (Wait, can an ear actually glaze over? I think 've done it.) What if there were an independent, third party means to capture and make visible the values we build into high performance homes and retrofits? In this episode, co-founders Cynthia Adams and Robin Lebaron join us to explain how Pearl Certification is truly transforming the housing market. They're on a mission to make visible the invisible aspects that contractors know about. The elements that make all the difference in the comfort, health, safety, resilience, and energy efficiency of a home. They are achieving this by qualifying an elite network of contractors and real estate professionals. These professionals work to improve home performance and ensure Pearl Certified homes are properly marketed and valued. This isn't a one and done effort. As your customers improve their homes, they continue to get credit for these improvements over time. The value of their high-performing home becomes visible at the time of appraisal for refinance or sale.

"I've been struck again and again by how important measurement is to improving the human condition." Bill Gates Lend us your ears as Kaleb and Bill have a very fun interview with Ben Reed, VP of Products at TZOA, a relative new comer to the world of measurement products. TZOA's approach with the Haven product is totally unique: a retrofittable residential air quality monitor that lives inside the central air handler and can control 1 or 2 systems that can impact air quality. Not just measurements/sensors, but control/solutions. This product is exclusively available to qualified contractors and is NOT a DIY device. In addition to a great streamlined product, the dashboard is AMAZING, largely due to the tight ties between the contractor-beta testers and clever product developers.
