President’s Message


Winter is here and hopefully it was a smooth transition for everyone and their buildings. Paul Schack is lining up a great evening for us, with a social hour, nice dinner, and interesting topic. This month's chapter theme is Research Promotion. Alex Bakel will have raffle tickets for sale at the meeting. Bring cash for raffle tickets! As a young and tech-savvy guy he will also have the capacitiy to serve as a Venmo-powered ATM, if you are so inclined. He has done a great job wrangling up raffle prizes from nearly a dozen generous contractors and vendors in the area. Don't miss out on the opportunity!

The ASHRAE Handbooks, among other resources from Society, are driven by research funded through ASHRAE. The University of Wisconsin-Madison draws a lot of these funds for research projects, and actually Wisconsin gets more RP dollars back than it sends in. So this is a great investment for you as well as the local area.

There are also options to support Scholarships for students, as well as Young Engineers in ASHRAE efforts. Promoting students and young members is how we drive interest and keep our industry healthy; it is also a focus for our Chapter this year. Please consider donating at

The Winter Conference is approaching, from January 12-19 in Atlanta. Reserve your spots by the end of the month for registration savings!

Hope to see you at the meeting!

The Psychometrics and Subtleties of Drying Hops and Hemp

Starting in 2005, Dan developed a drying and processing method that better preserved the aromas and oils in pelletized hops for the craft brew market to help his hops company push ahead of the larger growers of the Pacific Northwest.  This was primarily achieved by developing a low temperature drying method that provided a better flavor profile than just “Beachwood”.

Fast forward to 2018, after leaving his position at the UW and selling the hops business, Dan landed at Quest, Therma-Stor’s commercial dehumidifier division.  Low and behold, Quest’s Gardening division leads the market in providing dehumidification to the indoor grow market…yes folks, that means cannabis.  Much like the world of hops, the marijuana and hemp market is ripe with misinformation, anecdotal drying/curing methods and an utter lack of understanding of the fundamentals of drying herbaceous materials.  It is truly an art with very little science…and even less engineering.  You can even learn to build your own Hop dryer in 420 easy steps!

In December’s ASHRAE chapter presentation, Dan will provide a humorous trip through the world of processing hops and his insight into the coming world of processing cannabis products.


Daniel J. Dettmers

Sales Engineer

Dan Dettmers spent 23 years at the U.W., providing applied research, technical assistance and training to the HVAC and refrigeration industries.  In his spare time, Dan, as part owner of Gorst Valley Hops and Bine Implement, developed harvesting, drying and processing equipment for his own farm and many others in the small-scale commercial hop grower market.  Since the summer of 2018, Dan has been working as a Sales Engineer for Quest commercial/industrial dehumidification equipment where he specializes in expanding Quest’s desiccant offerings to the Cold Chain market.

While it may seem early, now is a good time to start thinking about the annual ASHRAE Technology Awards. 

Established in 1990–1991, the Technology Awards Program applies to new and retrofit applications in seven categories: Commercial Buildings, Institutional Buildings, Health Care Facilities, Industrial Facilities or Processes, Public Assembly, Residential and Alternative or Renewable Energy Use, with separate categories for New and Existing Buildings. Award applications are judged with respect to energy efficiency; indoor air quality, innovation, operation and maintenance, cost effectiveness, environmental impact and quality of presentation.

The purpose of the ASHRAE Technology Awards is threefold:

  1. To recognize ASHRAE members who design and/or conceive innovative technological concepts that are proven through actual operating data.
  2. To communicate innovative systems design to other ASHRAE members.
  3. To highlight technological achievements of ASHRAE to others, including associated professionals and societies worldwide, as well as building and facility owners.

All current members of ASHRAE and its Associate Societies may submit entries. Entrants must have had a significant role in the design or development of the project.

Last year we were able to send two projects to the regional level, where they were awarded in their category. 

We hope to see some great submissions again this year, so think of a great project you've done recently! (Note that projects should have a full year of energy usage data by September of 2019.) Winners will be announced for our chapter level at the April meeting. Winners will be sent on to the regional level to compete against other chapters, as several Madison entries did last year. 

So start looking through your project portfolio, and feel free to contact me with any questions.

Technical Committee Member Highlights

Our Madison chapter members are heavily involved in ASHRAE Technical Committees (TCs), with nearly 50 total people involved in some capacity. This month, we’d like to highlight a few of our member’s TC involvement.

Fred Betz

Building Performance Department Head, Affiliated Engineers, Inc.


  • TC 2.8: Building Environmental Impacts and Sustainability, Member
    • Past co-chair of Water:Energy Nexus
    • Working on a variety of issues including the Water:Energy Nexus and Resiliency
  • SPC 191P Standard for the Efficient Use of Water in Building Mechanical Systems, Chair

Jeff Boldt

Managing Principal – Director of Innovation & Quality, IMEG Corp

TC 2.6 Sound and Vibration – Consultant or maybe just corresponding member

I have (almost) a MS in Acoustics and Vibration Control. I’m trying to get the current chair (Erik Miller Klein) to be appointed chair of the 189.1 Acoustics Discussion Group. I led it for the last 6 years, and we rewrote the entire chapter, but need someone who is a fulltime acoustical consultant to take the next strides. TC 2.6 is also in the midst of significant revisions to their handbook chapter (although my opinion is that it might be the best chapter in all of the handbooks, and I’ve read nearly every one – if you read it from end to end, you are an acoustical consultant with everything but experience).

TC 3.6 Water Treatment – Member + Handbook Committee

Complete update of Handbook chapter. I’m one of the 3 primary persons working on the update. I’ve presented at ASHRAE conferences in the past few years about the engineer’ role in legionella control and about a workbook I created about whether you need a water softener for your application and with your feedwater.

TC 5.2 Ductwork – Consultant (I asked only to be a consultant because 90.1 meets at most of the same times and I could hurt their quorum)

Duct system leakage is a big topic. I’m working on potentially requiring leakage testing of ducts below 4” pressure class and am trying to get data from committee members about costs to test for leakage class, which is very different from seal class. I’m the primary editor of the acoustical chapter of the upcoming revision to the Duct System Design Guide and when I have time a commenter on the other sections.

TC 8.6 Cooling Towers and Evaporative Condensers – Member

Cooling tower GPM/HP is always being considered in 90.1. A new standard for dry coolers (maybe we need to change the committee name) was approved and, subject to public review, added to 90.1-2019.

SSPC 90.1 Energy Code for Buildings, Except Low Rise Residential buildings

Chair of Mechanical Subcommittee

Crashing to complete as many energy conservation addenda as possible for the 2019 code. At the October in-person meeting (we meet in person 4x per year + monthly for the full committee + monthly for each subcommittee + I and the other subcommittee chairs meet monthly) probably the largest changes are a potential requirement for condensing boilers (this one WILL get public review comments) and a clearer delineation of which spaces fall under 90.1 vs. 90.4 (Energy Code for Data Centers). Updated most of the equipment energy efficiency requirement tables. 90.1 is a LOT of work now that I’m the MSC chair, but worth it!

Guideline 36 Advanced Control Sequences – Member (this has enough momentum to be in continuous maintenance)

The Guideline has been published. I gave a talk about this at the Madison chapter and got Ron Bristol added to the committee (a great addition of a real user of controls and we had almost zero Owners until Ron joined). I also gave a talk about it at a conference in Orlando on Monday. The sequences that are published are air-side sequences. The next steps are:

  • Hydronic Sequences – I sent all of IMEG’s sequences to Steve Taylor (Taylor Engineering has the contract for the ASHRAE Research Project for hydronic sequences) partially because I wanted our ideas considered, partially because Steve and I are good friends, and partially because Steve lives in San Francisco and I didn’t want all of our systems to freeze!
  • Update Air-side sequences based on comments from users
  • Promote the Guideline. If enough engineers and owners adopt it, IMO there will be large cost savings for owners and engineers plus reduction of liability for engineers.

A Past President’s Reflection

To me ASHRAE is an organization of members dedicated to the “sharing” of our knowledge for the benefit of all. Sharing is both receiving and giving. We all receive the benefits from the ASHRAE handbooks, The ASHRAE Journal, the newsletters, the meetings, and conferences sponsored by ASHRAE. But what about the giving back? Someone has to give in order for us to receive. Someone has to plan the meetings, organize the conferences, write the papers, and raise the money for research.

I felt a need to give back and share my knowledge. Being an active participant in ASHRAE is one way I could give back. Going through the Board of Governors and the chairs gave me a chance to give back. I learned more about ASHRAE, felt good about planning and executing the chapter meetings, felt good about raising money for research and scholarships, and had the chance to interact with other board members and with other chapters at the CRCs.

I am proud to have served you and would recommend to all of you to find your way to give back.

Gene Nelson
2007-2008 Madison ASHRAE Chapter President
