    Measuring Part 5, Refrigerant Charge, of the RESNET/ACCA/ANSI Standard 310

    Joe Medosch {med-osh}

    Joe Medosch will demonstrate how simple it is to measure Part 5, Refrigerant Charge, of the RESNET/ACCA/ANSI Standard 310 This can be completed by Anyone!

    Procedure: using your hand, confirm cold air inside and “beer can cold” refrigerant line outside = Done. Can it be done accurately and w/o being EPA Refrigerant charge certified = Yes. Can you also measure system SCFM, possible return duct leakage, refrigerant charge including superheat and subcooling and check for 100+ faults in the system w/o pressure gauges? measureQuick does!

    Over a dozen studies confirmed most AC systems have either airflow or refrigerant charge faults (or both). A 2018 DOE study found heating and air conditioning installations had at least one fault in 70–90% of homes, and when duct leakage is considered, this number increases to 90–100%. Improper installation leads to increased energy use, comfort issues, warranty claims, callbacks, and higher H/AC repair costs over the lifetime of the equipment.

    Fixing these two faults alone has the potential to decrease residential cooling energy loads by 5–10%. Researchers at NREL estimate that central air conditioners and air-source heat pumps in the US waste 20.7 terawatt hours (TWh) of energy per year due to equipment faults. Convert that to energy generated by hydroelectric - it’s 5.7 times the volume of Lake Mead at its highest level. Which is 8.5 trillion gallons of water.

    Learning Outcomes:

    • Identifying the requirements for part 5 of the RESNET/ACCA/ANSI Standard 310
    • Calculate refrigerant pressure from temperatures
    • Understanding how this option confirms compliance and reduces failures for your builders
    • Learn how to add this to the other sections of Standard 310 and complete the entire compliance pathway

    Lower the Guardrails and Lean Into It

    Nick Hurst

    If you’ve been working in the home rating industry for at least a year or so, you may have recently asked, “Why do these ‘industry standards’ and ‘national certification programs’ always seem to be changing?” Or, “Are you serious—they’re releasing yet another update?” Or maybe you’re wondering, “Why can’t they just settle on something simple and stick with it?”.

    Learning Outcomes:

    • Understand how home certification programs create healthier homes without undue complexity.
    • Identify the right balance between rigor and affordability.
    • Uncover how the rating industry helps shape future certification requirements that accelerate the market adoption of high-performance homes.

    Colby Swanson

    Buckle up and get ready for this session on how to do more with less in the construction industry. We are currently experiencing a significant shift towards offsite and prefab methods because onsite methods aren’t working fast enough to solve our housing challenges. In this presentation, we’ll eliminate proof points of this shift, as well as explore ways the rating and home building sectors can, and should, participate and lead as the construction industry repositions itself to do more with less.

    Learning Outcomes:

    • Demonstrate how to read tea leaves: market signals.
    • Discuss the wind direction and why it is important.
    • Summarize how alternative building methods can help build faster and cheaper.
    • Identify ways to prepare for future changes in the construction industry.
    “Where Do I Go From Here?" Career Paths in the Home Energy Rating Industry

    Scott Doyle

    In years past, there has been a lot of hand-wringing over the perceived issue that there is no real defined career ladder for HERS® Raters.  Yet the absence of well-established paths does not have to doom us all to stagnation.  Every well-worn path was begun by those who blaze the first trails.  This interactive session will delve into the obvious and sometimes not-so-obvious potential career progressions as we highlight the real-life career paths of a group of professionals with diverse backgrounds who collectively hold some of the more significant, and in some cases, high profile jobs in the residential energy space.  Through audience participation, we will discuss professional credentials and what matters to employers.  The intent is that this session leaves each person reflecting on their own personal and professional goals with renewed clarity and perhaps even a bit of inspiration.

    Learning Outcomes:

    • Describe the differences between certifications, designations, and other industry credentials
    • Understand how employers prioritize professional credentials among other traits like skill, aptitude, work ethic, seniority, etc.
    • List certifications, designations, and other credentials that are relevant to the HERS Rating Industry
    • Develop personalized list of credentials to target based on each HERS® Pro’s own individual career goals

    Your Questions Answered
    RaterFest is a truly unique experience - it's ok to have questions! Don't see the answer you're looking for here? Contact Sunny!

    What clothing should I bring to the conference?

    Casual and comfortable attire! Being in the mountains we have unpredictable weather, so pack layers! Bring a jacket, hat, mittens and a scarf if you prefer. Anything that keeps you warm on those colder days and nights.

    What about shoes?

    Comfortable walking shoes, hiking boots if you plan on hitting the trails, slippers for hanging out in your lodge or cabin. There are community showers in the cabins and lodges. Bring your shower shoes if this is something you prefer.

    I am flying into Denver International Airport, how do I get to the venue?

    Your best option (if you don't intend on renting a car) will be a ride-share service like Lyft or Uber from the airport to the venue. We will also set up a carpooling form so you can split the ride-share cost with a fellow attendee. Don't forget your RETURN ride back to the airport. It will be important for you to set up your return ride-share prior to your Sunday departure. The location is a bit remote and can be hard to find a ride-share if you wait last minute.

    Will you have a first aid kit?

    Yes! We will have Band-Aids, Neosporin, allergy medicine, ibuprofen, and bug spray. If you need something specific for your medical needs, please be sure to bring that with you.

    Where is the nearest hospital?

    Centura St. Anthony Summit Hospital (33.2 miles)
    Denver Health (40.8 miles)

    Is there WIFI at the venue?

    Yes, although it can be spotty. Feel free to bring your laptop and charging cord. You can also bring a notebook and paper!

    Will my cell phone work up in the mountains?

    This is another tricky question. You should have decent cell reception depending on your cell phone carrier, but there is no guarantee. The venue has landlines available if you need to place a call.

    Does the venue have proper lighting at night?

    Bringing a flashlight or headlamp is a great idea. The mountains tend to be very dark unless it's a clearer night and the moonlight can help pave your way.
