We're running it again, Integrated HVAC Engineering: Mastering Comfort, Health, and Efficiency.

2017 ASHRAE Winter Meetings
Las Vegas, NV

Seminars made possible with funding from Uponor.

Seminar: Ducts? Who Needs Ducts? Hydronics the Original Unducted System

Overview: In the land of comfort, educated home owners are changing their thermal expectations from HVAC systems, and contractors are on the front line hunting for the best solutions. Regardless of ducts or pipes, the “migration” of heat takes a basic understanding of what works and what doesn’t. It is not easy to figure out the right design for the application, especially as homes get more efficient. Low­cost ducted systems may not always
work right or be the best fit. This seminar looks at best practices for distributing heat in residential air and hydronic systems, including ducted and radiant design options.
Learning Objectives:
1. Describe best practices for designing and installing flex duct systems.
2. Describe best practices for designing and installing hard duct systems.
3. Describe best practices for designing and installing hydronic radiant systems.
4. Define how proper distribution of heat contributes to perceptions of thermal comfort.

Go here to post your password request (please don't post requests in other Linked-In groups, our admin. people don't monitor them)


If you have questions please post them in the IEQ group. Before sending us private emails for assistance see our Services page>>

Top 5 reasons why we may not have sent you the password:
1 You have not joined our IEQ group as per instruction step #2.
Why is this important? Linked-In does not allow us to send private emails to non-members.
2 You have not posted a password request at the IEQ group as per instruction step #3
3 You have not included the text string as per instruction step #3
4 You have sent us a private email requesting the password - see instruction step #3 and step #4
5 You have posted a request in another Linked-In discussion group - see instruction step #2

Background - we have well over 800 pages at the website many with course slides and spreadsheet tools. In order for us to manage who wants what and from where, our administrative team assigns a password to a URL and uses the IEQ Linked In group to manage the request. Additionally our email is backlogged to last year so sending us private emails requesting passwords for this years conference material is an exercise in futility...if you really want the resources - please follow the instructions.
