President's Corner 

It’s hard to believe the holidays are already upon us. I’d like to take a quick moment to say that I hope all of our NCC ASHRAE members had an enjoyable Thanksgiving holiday. Hopefully your holiday was filled with family, friends, football, and great food. Last month I challenged all of you to follow up September’s large turnout with another strong showing in October, and you did just that. Thank you to all of the NCC ASHRAE members who attended our chapter meeting on October 15th. I’d like to extend a special thanks to all of the student ASHRAE members who came to the meeting. We had a fantastic student turnout, and it was great to hear about the projects they are working on. 

Speaking of students, I’d like to take a few minutes to tell you about a recent experience I had thanks to our Student Activities Committee. In addition to working with student chapters at local colleges and universities, the committee goes into the community to help expose young students to science and engineering. This is done through elementary schools, Boy Scouts, Girl Scouts, and other groups. We have a full slate of Student Activities events planned, more events are most likely on the way, and we could really use volunteers to help out. 

Two weeks ago I had the pleasure of attending my first ever Brownie Girl Scouts meeting. I had no idea what to expect, but the girls were engaged, asked great questions, and were really excited about the experiments we showed them. It was a great time. I encourage anyone who might be interested in attending an event to reach out to our Student Activities Committee Chairs, Mary Opalka and Mikelann Scerbo. If your experience is anything like mine was, you’ll be glad you did. Mary and Mikelann can be reached at 

I’m also very happy to announce that Roger Chang, our current Government Activities committee chair, recently received some great news from ASHRAE. Those of you who attended our September meeting may remember that Roger won a Region III Technology Award and that his project was under consideration for Society-level recognition. We recently found out that Roger was selected as a First Place winner of an ASHRAE Technology Award in the Commercial Buildings – Existing Category for the Wayne N. Aspinall Federal Building and US Courthouse project in Grand Junction, Colorado. Roger will receive his award in Chicago in January, and his project will be featured in the March 2015 issue of the ASHRAE Journal. Congratulations, Roger! 

Our next meeting of the 2014/2015 season is scheduled for Wednesday, December 10, at the Hilton Arlington Hotel, and I think we have another great set of programs lined up. We’ll be teaming up with ASPE as part of our first joint meeting of the year. Our dinner topic, Legionella, is one that resonates within both of our industries. I look forward to seeing each of you there.

PES Presentation
Constructability/ BIM
-Speakers: Dr. John Messner

This presentation will provide an overview of a structured procedure for integrated teams to plan and communicate their Building Information Modeling (BIM) implementation strategies on a project with a particular focus on the role of the mechanical design and construction professions. A proposed method for BIM Project Execution Planning has been developed through a buildingSMART Alliance project by the Computer Integrated Construction (CIC) Research Group at Penn State. This planning method includes a four step procedure:

  1. Identify BIM goals and uses
  2. Design the BIM process for the project
  3. Develop information exchange requirements for exchanges between project participants
  4. Define the project infrastructure to support the BIM implementation

Dinner Presentation
ECM Motors
-Speaker: Gary Hamilton and Ionel Petrus

The presentation will discuss the motor types available in HVAC design. The theory behind ECM Motors and the reason why it is the future of HVAC pumps, and fans technology. It will also highlight where ECMs are currently used so that the audience will understand that the technology has been used for a while. The presentation will show the audience how the ECMs motor design was applied to in-house project. It will also question the reasons why ECM are not specified for all HVAC fans. 


  •          Facts
  •          Motor Types
  •          ECM Theory
  •          ECM temperature Rise
  •          ECM Benefits
  •          Where are ECM used?
  •          ECM application in AHUs
  •          Why don’t Engineer Specify them more?
