Winter YEA Event!


Young Engineers in ASHRAE (YEA) is sponsoring a social event at the Maple Hall Bowling alley downtown on Saturday, March 9th. YEA is sponsoring the event, but as always, members and potential members of all ages are welcome to come. Maple Hall is a small bowling alley located in the historic JC Penney building downtown. The space has 11 lanes, a full-service bar, small plate food offerings, and a lounge area for those, such as myself, not too skilled with a bowling ball. The event should be a lot of fun and a great opportunity to socialize with fellow ASHRAE members.  It is a small venue so please RSVP to by Friday, March 1st so we can plan for and reserve adequate space.

Put ASHRAE In Your New Year Plans!

Andrew Meyers has finalized our meeting schedule for the remainder of the year and all meeting topics are posted on the “Meetings” tab. Additional detail and speaker biographies will be added in the near future. Please notice that the January and March meetings are scheduled just a bit later in the month to accommodate the ASHRAE Show in Atlanta and Spring Break. We hope that you will note these dates and make ASHRAE a part of your plans!

City of Knoxville Code Changes and Forum

Erin Gill, Director of Sustainablity for the City of Knoxville, has advised us about the following opportunities to learn about upcoming code adoptions for the City. Her message follows, as we want all of our members to be aware of these changes.

Good Morning (Green) Building Industry Friends,

The City is preparing to adopt the 2018 editions of the International Code Council construction codes. Historically, the adopted codes have been amended to reflect earlier editions to minimize construction process changes. This adoption will be somewhat different in that we intend to adopt the 2018 code editions with minimal amendments.

Plans Review and Inspections Staff have been reviewing the 2018 codes the past six months. Please join our staff next week Monday, July 30, 2018 through Thursday, August 2nd from 6:00 p.m. to 7:30 p.m. at the Public Works Service Center on 3131 Morris Avenue to learn more about the changes for each code.

The following schedule has been developed to discuss changes with those interested:

Monday, July 30, 2018

2018 International Residential Code
2018 International Swimming Pool and Spa Code

Tuesday, July 31, 2018

2018 International Building Code
2018 International Energy Conservation Code

Wednesday, August 1, 2018

2018 International Plumbing Code
2018 International Fuel Gas Code
2018 International Mechanical Code

Thursday, August 2, 2018

2017 National Electric Code

From a green building perspective, we are evaluating an option to lightly increase a few commercial energy efficiency standards above and beyond base code. Your input as we consider this option would be very valuable.

Please feel free to pass this along to others who may be interested.

Erin Gill
Director, Office of Sustainability
City of Knoxville, TN


April Meeting will Feature Student Design Group


Our April 25 meeting, will feature a presentation by Dr. William (Bill) Miller's Senior Design Project Team. Dr. Miller is a Research Scientist at Oak Ridge National Laboratory as well as an instructor at the University of Tennessee. Dr. Miller received his Bachelors, Masters, and Doctorate Degrees in Mechanical Engineering from the University of Tennessee. He has led a group of undergraduate Mechanical, Aerospace, and Biomedical Engineering (MABE) students as they complete their Senior Capstone Project.

Bill's current group of students are in the process of building a combined cooling and power (CCP) system that cools air for use in comfort conditioning and generates electricity from waste heat. Rather than dissipate condenser heat to the environment, the refrigeration system will convert the primary refrigerant’s condenser heat into  electricity.The key challenge is to transfer refrigerant condenser heat to shaft power and drive a turbine/alternator set for converting high quality heat into useful electricity. Students have used the NIST REFPROP[1] v9.1 refrigerant routines and have modeled the refrigeration cycle using the MATLAB programming language which the School of Engineering at UT has licensed for student academic work. Students are building a prototype CCP with support from UT Facility Services refrigerant technicians.

We expect a good crowd for this meeting - come early and network with fellow ASHRAE members! Better yet, invite a friend or colleague to hear this interesting topic.

January Global Warming Program Cancelled by Cold Weather!

In a cold, Arctic blast of irony, our own Tom Werkema's "Update on Climate Change" program will have to be postponed to a later, hopefully warmer day. Snow, and a previous night's low of 9-degrees caused hazardous driving conditions along with the usual school cancellations, etc. in Knoxville.

Meanwhile, it was sunny and almost 30-degrees warmer in Anchorage, Alaska. Rumor has it that the annual summer lake party will be scheduled there, in order to take advantage of the newly tropic Arctic weather! Stay tuned for details!

Holiday Party Success!

Our 2017 Holiday party was a resounding success - we appreciate the efforts of many folks to secure, organize, and execute a great evening. Someone whispered that Anne Jacoby did more than her fair share - we  sure did appreciate it Anne! The event was once again well attended with young and old alike.

We wish all of our chapter a wonderful and merry holiday season! We will reconvene in Janaury and look forward to the New Year.
