October 2016 Program

The Wisconsin Chapter of ASHRAE is proud to announce that on Thursday, October 20th, Kishor Khankari, President of AnSight LLC, will be presenting on: Airflow Management for Healthcare Facilities. The presentation will cover the importance of HVAC configuration on airflow distribution of airborne contaminants in patient rooms and operating rooms. The presentation will also cover the applications of active chilled beams, radiant systems, and displacement ventilation in patient rooms.

Dr. Kishor Khankari, Ph.D. provides engineering analysis of HVAC solutions with physics based simulation software thru his company AnSight LLC. His software allows HVAC designers to optimize their system designs for efficiency and comfort in countless application types. Dr. Kishor is also a past Chair of ASHRAE Technical Committee TC9.11 Clean Spaces, and has great insight into solutions for achieving exceptional IAQ in several types of applications.

March 2015 Program

The Wisconsin Chapter of ASHRAE is proud to announce our next chapter meeting on March 19th. Ryan Hoger, Director of Corporate Training for Temperature Equipment Corporation,  will be presenting on Rooftop Unit Optimization. This topic will offer a continuation of some of our earlier discussions regarding RTU’s. For a full course description and background on our presenter, please see the write-up below.

The program will be held at a new venue for us, Dave & Buster’s located in Wauwatosa on Hwy 100, see www.daveandbusters.com.

4:00 to 5:00 PM – Registration and Networking (Cash Bar)
5:00 PM – Scholarship/Awards Presentation
5:00 to 6:00 PM – Presentation (Appetizers)
6:00 to 8:00 PM – Reception: Buffett Dinner & D&B Fun!



Packaged rooftop units (RTUs) are used to easily and effectively heat and cool more than 50% of all commercial buildings, but are they efficient?  The cooling efficiency improvements in the refrigeration circuits have improved slightly in the past 10 years and the average gas efficiency has improved from 80% to just 82%.  What else can we do to make a simple RTU use significantly less energy to heat and cool our structures?  A recent 2013 Department of Energy study explored this exact question and the solution is summarized by the term Advanced Rooftop Control or ARC.  This seminar will explore that ARC research and several options for existing (or new) RTUs to save 24 to 35% of the fan, cooling, and heating energy.

 Review of What We Already Know… but maybe don’t implement enough

  • Programmable Thermostats: recommended settings, OA interlocks, and Wi-Fi… duh, everything with an App is better
  • Economizers: dry-bulb vs. enthalpy, integrated economizing, and recommended settings… yes you have been too conservative
  • Demand Controlled Ventilation (DCV): basic concept, sensor reliability, recommended settings, and “is that allowed in Wisconsin?”
  • Code requirements, utility rebates, and energy savings calcs for all of the above

What is New?… or at least new again

  • Multi-speed fan control of “Constant Volume” systems
  • Name Game: Staged Air Volume (SAV), Single Zone VAV, Multi-stage Air Volume (MSAV)
  • How is SAV different than VAV?
  • What good is a VFD on a “constant volume” RTU?
  • How is it controlled?
  • Is it required by energy codes or standards?
  • Energy savings and utility rebates

What about ERVs, Variable Capacity Compressors, Dynamic Balancing Systems, and Magic Black Boxes… oh, we love those magic elixirs

  • It is not easy jamming 4 hours of topics into an hour, so we cannot cover everything
  • Never fear, we can direct folks to recorded webinars if they want to learn more about some of these technologies
  • And of course there is always cocktail time… Ryan would be happy to discuss any of these topics with you

December 2014 Program

The Wisconsin Chapter of ASHRAE invites you to attend a tour of ABB in New Berlin on December 18th. The tour of the facility will include an overview of the HVAC system and equipment, a visit through the mechanical room, review energy saving techniques that were implemented, along with a brief tour of the manufacturing facility.

ABB is a global leader in power and automation products.  The approximately 150,000 sqft ABB facility in New Berlin houses both manufacturing and office space.  The building recently underwent a major renovation, which included an entirely new HVAC system.  The system includes a central plant, thermal storage, FANWALL technology, adiabatic humidification, and an intelligent system utilizing BACnet communications.  In fact, this building was recently featured in the attached BACnet publication. 

After the tour we will have a reception with drinks and food at the New Berlin Ale House.


4:15 to 4:30 PM – Meet at Lobby of ABB
4:30 to 6:00 PM – Tour ABB
6:00 to 8:00 PM – Reception at New Berlin Ale House (Buffet Dinner)

February Program: Advanced Energy Design Guide

The Wisconsin Chapter of ASHRAE is proud to announce that on February 20th Ron Jarnagin (Distinguished Lecturer) from Pacific Northwest National Lab, located in Richland, Washington, will be presenting on Advanced Energy Guide Lines – Going Beyond Minimum Standards.

The Advanced Energy Design Guide (AEDG) series of documents is one of the most popular in ASHRAE’s history with well over a 100,000 copies in circulation.  Focused on providing clear guidance for achieving 30% energy savings in smaller commercial buildings, the AEDGs meet the need for a large number of projects where project budgets and design professionals might be in short supply.  The presenter chaired the initial AEDG for Small Offices as well as 3 additional guides and will offer perspectives on the partnership that contributed to the guides, the intent of the guides and how practitioners can apply the guides.

For Further information on Ron please feel free to visit the follow site: Ron Jarnigan

Topic: Advanced Energy Design Guide
Presenter: Ron Jarnagin
Time: 5:00 pm social hour,  6:00 pm dinner and presentation
