Building HVAC Science

Today we learn about how Amanda Hatherly has morphed the traditional approaches of technical training into something much more interactive and interesting. Over the last 8 years she helped to develop the Energy Smart Academy at the Santa Fe (New Mexico) Community College. She described some really cool online tools that help people understand the invisible and confusing aspects of heat and moisture flow in a building.

Bryan Orr and Bill Spohn spent 3 busy days learning, listening and absorbing the vibe at the world's largest HVACR trade show, the AHR Expo which took place in Chicago at the end of January 2018. Come walk the auditory aisles with these two friendly nerds and see where the market is headed as a whole and with specific products.

On this episode, Bill Spohn welcomes Bethany Profaizer and Amy Beley from Pearl Certification (www.PearlCertification.com). Pearl has created a unique and very cost effective, third party certification for the major "invisible" elements of a home: building shell (or envelope), HVAC/mechanical systems, energy baseload, home management and photovoltaic (PV) solar. Contractors actively working in any of these are disciplines are eligible to apply. Now active in 6 states and the District of Columbia, Pearl is partnering with new contractors and real estate professionals from across the country every day. Unlike other programs, there is no pre-qualification necessary for the home. Pearl has worked hard to create a system that integrates with contractor's sales and work systems, while providing a tangible record of the value for the home owner and real estate world. If you're a contractor who wants to get a lasting record (it stays with the property) that recognizes your good work, contact Pearl. Your customers will like the fact that they can get documented credit for your work when they go to sell. A third-party study found Pearl Certified Homes are getting 2-10% better prices to comparable non-certified homes. To learn more about becoming a Pearl Partner, contact Bethany at [email protected]
