On the Agenda for 2017

Opening the Window to the Builders Back Office
Bill Rectanus

This presentation will try to give you some insight into the builder’s world. Learn how builders make decisions and choose to move towards or away from building science and energy efficiency. Get an understanding of the different types of builders and how their structures push them towards the decisions they make? Get a sneak peek into home builders financials; how they price their homes, the types of margins that run their businesses and the risks they face in this very competitive business.

This interactive session should help you better understand your builder client, how they make decisions and who or what is the driving force behind making them. Learn how you can use this information to bring value to their design, their cost control and in the end drive them towards building better more efficient and healthy homes.

Learning objectives:

  1. Better understand the different builder types and building company structures.
  2. Learn how the different builder types make decisions and who is behind making them.
  3. Understand the builders financial structure and review the strains and limits it poses to a builders business.
  4. Review and learn how builders price their homes and how that exercise effects their decision making process.
  5. Learn how building science and energy efficiency fit into these different building company models.
  6. Gain an understating of how you can help builders limit risk and control cost while moving towards a more energy efficient, healthy and durable product.

What RaterFest! Previous Attendees Have to Say…

“RaterFest 2016 was a BLAST! It was great to meet other HERS raters from across the country and to collaborate with each other on better ideas and practices to become better RATERS!” Grant Warner, RF! 2016

“Every year I look forward to breathing in the mountain air and being surrounded by so many passionate, knowledgeable and experienced Raters and building science geeks. It’s the mid-year power up I need and I always leave feeling energized and well equipped to take on the challenges we face day-to-day in this industry.” Cristen Burrell, RF! 2016

“RaterFest! is not a conference. It is a gathering. It encourages good vibes & camaraderie, and I’m refreshed and a better person for having gone. Plenty of breaks, no stuffy conference rooms, and a venue that encourages sharing. Energylogic knows what’s important.” Blake Reid, RF! 2016

“RaterFest 2016 was a great event with great people, excellent conversation, and an amiable environment conducive to both learning and fun. I am impressed, as always, with the level of engagement from everyone in attendance and I look forward to participating again next year.” Ari Rapport, RF! 2016

“RaterFest 2014 was a great event in a beautiful setting with interesting attendees and presentations. It is probably the most enjoyable way to get CEUs I could imagine. Thanks to EnergyLogic for coordinating this event!” Jeremy Draper, RF! 2014

“What a fantastic event! Great facility with an awesome group in attendance. Excellent content as always. Thoroughly enjoyed the fire-side chats on topics ranging from Building Science to Code to kids. The food and accommodations were outstanding and the beer… ah, the beer was truly the nectar of the gods. Being largely disconnected from the outside world made it so much easier to connect with each other at RaterFest! 2014!!” Stephen Davis, RF! 2014

“First time to Rater Fest. Solid training and great networking. Thanks for making it happen!” Shawn LeMons, RF! 2014

“I had a wonderful time for the third year in a row! Rater Fest is a great way to meet associates, update our knowledge and band together to energy efficiency in buildings.” Nancy Kellogg, RF! 2014

“The element of Raterfest that made it stand out from other conferences was the specific focus on the role of the rater. Networking with such a diverse group of people doing that same work that I do was invaluable for me. And the site was fantastic!” Heidi McCullough, RF! 2014

“I am a huge fan of RaterFest. The organizers acheive a perfect balance of learning, engaging conversation, and nature … a sort of “unconference” that you walk away from feeling like you were part of something special! When was the last time you could say that about a conference? I know why it’s called RaterFest now … Looking forward to the next one!” Colby Swanson, RF! 2014

“What a great time! It’s rare that you can pack so much education and fun into the same event. As a code official, it was great to hear what is happening on the rater side of things and what is coming down the pike as far as innovations, policies, procedures and technology. I look forward to enhancing the rater/code official relationship and already looking forward to next year’s event!!” Shaunna Mozingo, RF! 2014

“Excellent gathering of building energy professionals.” Jack Beal, RF! 2014

“Great conference for catching up with folks in a relaxed and intimate setting while also knocking out those CEUs!” Laura Capps, RF! 2013

“I appreciated the balance between lecture and networking – with such a small group, the structure was particularly powerful.” Thiel Butner, RF! 2013

“Just like mother nature, RaterFest! is a force to reckoned with!” Andrea Ingalsbe, RaterFest! 2013 attendee

“Thank you so much for having Rater Fest, I totally enjoyed attending this event. I learned alot but meeting fellow raters was the best!” Nancy Kellog, RF! 2013
“This was an extremely informative session, and I truly enjoyed the hospitality. We will begin implementing some of the tactics presented, to improve our performance in the field. ‘What a Fest-Raters!’” Stephen Kassa, RF! 2013

“Tired of your old, dry, stuffy home performance conference? Trade it in for a fresh, lively, intimate, hands-on mountain high conference with down-to-earth building experts. Come to Raterfest!” Graham Davis, RF! 2013

“RaterFest! is truly unique within the mix of home performance conferences–national in scope yet small and intimate, high level, attracting a very unique group of professionals from the industry, and NOT in a Holiday Inn ballroom! My favorite event of the year.”

“Honestly, I was anticipating a bunch of nerds discussing building science. Turns out RaterFest! brought together the funnest, most dynamic group of people I have been with in a long time. There was no shortage of building science talk, but it was blended with the perfect amount of laughter, and beer, to make me want to come back again and again. Thanks for a great weekend!”
