    EP105 Unpacking the ANSI-RESNET-ACCA-ICC 310 HVAC Rating Standard series Tasks 2&3, Duct Leakage and Blower Airflow With Steve Rogers

    Simplicity is the outcome of technical subtlety.
    It is the goal, not the starting point.
    Maurice Saatchi



    It’s worth repeating that HVAC equipment is often the largest energy-consuming system in a home.
     
    While listeners have likely run duct leakage and blower airflow tests, how did we arrive at the straightforward, almost simple test equipment and methods used today?
     
    What is the science behind the tests?



    Today’s podcast continues down the technical trail with part two of a three-part series on cracking open the details of the ANSI/RESNET/ACCA/ICC Standard 310. We are joined by Steve Rogers, President of The Energy Conservatory and an expert in pressure and flow measurements.
     
    Steve introduces us to the technology used to measure duct leakage and blower (air handler) airflow and the power of proper diagnostic methods and techniques.
     
    Some of the educational resources mentioned may be found here: www.HVACairflow.com, which includes materials prepared by Ed Janowiak, Manager of HVAC Design Education for ACCA.
     
    After listening, you will better understand the “why and how” of getting the duct leakage and blower airflow dialed in.

    EP103 KB Home Creating More Water Efficient Homes with RESNET’s HERSH2O and EPA WaterSense with Jacob Atalla

    EP103 KB Home Creating More Water Efficient Homes with RESNET’s HERSH2O and EPA WaterSense with Jacob Atalla

    “Positive attitude plus effort equals performance.”
    Tommy Tuberville



    As we hear more about droughts, what is the impact on residential new construction?
     
    Why did KB Home feel it was important to commit to the WaterSense label for all future home builds in Arizona, California, and Nevada?
     
    How is KB Home using RESNET’s HERSH2O water efficiency rating system to address water consumption without sacrificing performance for homeowners?
     
     
    Jacob Atalla, VP of Innovation and Sustainability for KB Home joins us to discuss the important work is being done to create more water efficient homes using RESNET’s HERSH2O water efficiency rating system. 
     
    We discuss the importance of water efficiency, the trends over time and the stakeholders that value water efficiency.
     
    Jacob also shares the background on RESNET’s HERSH2O water efficiency rating system, how it was created and how it is an easy “add” to the work performed by a HERS Rater.
     
    Jacob helps us understand the long history of work KB Home has done and some of the awards they have received as a positive force in this area.
     
    According to the US EPA, WaterSense labeled homes use at least 30% less water than a typical home and can save a household 50,000 gallons of water annually, on average. 
     
    To date, KB Home has built over 18,000 WaterSense labeled and Water Smart homes — more than any other homebuilder — and installed over 900,000 WaterSense labeled fixtures. The company estimates that these homes, together with the WaterSense labeled fixtures within them, conserve approximately 1.6 billion gallons of water annually.
     
    We also touch on the water/energy nexus discovering that Las Vegas homes built by KB Home (as part of an EPA study) saw savings of an extra 1,100 kWh annually (beyond the savings estimated by the RESNET HERS rating alone) due to the overall water conservation, a portion of which is hot water conservation.

    EP101 Freddie Mac’s Green Mortgage Program with Simone Beaty

    EP101 Freddie Mac’s Green Mortgage Program with Simone Beaty

    “Sustainability is no longer about doing less harm. It’s about doing more good.”
    Jochen Zeitz



    How is the topic of energy efficiency in new single-family homes addressed in the mortgage industry?
     
    What pillars of ESG (Environmental, Social & Governance) are at play in this system and who are the players?



    We are joined on today’s podcast by Simone Beaty who is the Director of Housing Policy with Freddie Mac.
     
    Freddie Mac was chartered by Congress in 1970 to support the U.S. housing finance system and to help ensure a reliable and affordable supply of mortgage funds across the country. 
     
    Freddie Mac operates in the U.S. secondary mortgage market, buying loans that meet their standards from approved lenders. Freddie Mac then pools the mortgages it buys into securities, which they sell to investors around the world.
     
    Drawing on her in depth experience in the financial services industry and strong finance related skills in housing policy strategies, Simone explains how Single-Family Green Mortgage Backed Securities support Freddie Mac’s focus on financing energy efficiency in new and existing single-family homes.
     
    These activities help to preserve home affordability over time and attract capital to promote sustainable activities through mortgage financing.
     
    Simone shares with us data, statistics, and trends on topics such as remodeling and repairs, work from home impact, and solar installations. She describes the criteria necessary for qualifying mortgages including the minimum HERS score.
     
    She notes the important impact of the increase in HERS ratings and how this helps more builders relate to more consumers the ties to sustainability that come from Home Energy Ratings.

    EP100 HERS Modelers Ensure Consistency of Input in HERS Ratings with Joshua Anderson and Scott Doyle

    EP100 HERS Modelers Ensure Consistency of Input in HERS Ratings with Joshua Anderson and Scott Doyle

    “Passion is what gives meaning to our lives.
    It’s what allows us to achieve success beyond our wildest imagination. 
    Try to find a career path you have a passion for.”
    Henry Samueli



    The RESNET ecosystem continues to grow and morph as demand increases and external factors change.
     
    What new opportunities exist for those already in or considering entering the world of home energy ratings?
     
    Are there career specializations available?




    In today’s podcast, Josh Anderson (TopBuild) and Scott Doyle (RESNET) help us understand the purpose, scope and functions of the RESNET HERS modeler designation.
     
    In 2020, the RESNET Board of Directors voted for the creation of a new RESNET HERS Rater modeling designation with a goal of increasing the consistency in the input in HERS Ratings through the training and certification of persons who conduct the modeling and analysis using accredited HERS Software Tools.
     
    Upon certification, HERS Modeler candidates are issued a unique RESNET Modeler ID which can be used for single or multiple HERS Software Tools.  In many ways this certification is like the current Rating Field Inspector certification for field inspection and testing including candidates being posted on the RESNET Registry.
     
    Josh discusses how this is a natural evolution of the industry, especially as businesses scale. He also notes this helps to create an alternate career path within the RESNET ecosystem as it embodies a different skillset and an alternate work environment (office vs. field) for a more diverse workforce. 
     
    Scott gives us an overview of the formal training required and notes that continuing education will be required to maintain the certification. The continuing education will be offered by the accredited HERS Rating Software Program developers. 
     
    Scott notes that certified RESNET HERS Raters, having taken inputs and plan reviews as part of RESNET HERS Rater Training, will automatically receive the new certification without any additional fees, yet would still have to meet the continuing education requirements.

Love this podcast!

This is such a great podcast. Bill is a excellent interviewer and keeps the listener understanding the topic when a guest goes a little deep, explains relevant topics, clears up misconceptions (like how ICC and RESNET intersect, and how the newer RESNET QA system is working to improve consistency and accuracy), and I love Bill’s fun “thought for the day” at the end of each episode. I have learned a lot and intend to listen to every one. Thank you RESNET for this insightful, educational, and inspirational podcast.
