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

See us at these 2016 events, ASHRAE AHR (Orlando), Better Buildings: Better Business (Wisconsin), Uponor (Las Vegas) ACI (Austin), Humid Climate Conference (Austin), ASHRAE (St Louis), ASHRAE IBSPA SIMbuild (Salt Lake City)

Better Buildings: Better Business 2016
Wisconsin Dells, WI.
Hosted by Seventhwave

Workshop by Robert Bean for this co-presented workshop made possible with funding from Uponor.


Day 1 workshop: Wednesday, March 2nd, 8:30am - 5:00pm
Day 2 seminar: Thursday March 3, 2016 10:30am - 11:45am and 1:30pm - 2:45pm 

Hydronic Based Hybrid Systems for Efficiency and Comfort

Abstract: This session will take students through key aspects of why and how hydronic-based hybrid systems enable conditions for thermal comfort and energy efficiency. Participants will learn big picture concepts; see examples of fully integrated and very simple applications; and get into the finer details required for cost effective system performance.

Workshop seminar #1: Thermal Comfort: First Principles

Before manufactures and contractors adopted the role of comfort providers, it was the healthcare professional that studied and defined spaces suitable for occupancy. Somewhere in the transition from doctors to contractors the root understanding of thermal comfort got lost. In this reintroduction to the first principles you will learn why building codes and reliance on air temperature and humidity have always been and will continue to be woefully inadequate proxies when it comes to establishing acceptable conditions for human comfort.

It is not a requirement, but a recommendation that you bring these with you to the workshop on your own laptop etc. The Excel tool will be demonstrated live and you'll have a chance to use it during this presentation. Print the worksheet if this better serves your needs.

Caveat: Use of the spreadsheet is subject to our legal terms and conditions. It is not an engineering design tool. It is a tool to understand the effects of surface temperatures on thermal comfort. Read the legal terms and conditions before using this spreadsheet.

Workshop seminar #2:  Integrating Design:  Building Enclosures, Architectural-Mechanical Interfaces To Enable HVAC Energy and Exergy Efficiency

The root of all evil in sustainability begins with the myth that 1st Law of Thermodynamics "energy efficiency is the end game". This conviction is masking the bigger problems associated with sustainability and reinforcing people beliefs that they are doing the right thing. In fact every time someone improves the energy efficiency of a building system, i.e. insulation and air-tightness etc. (good things) and is associated with combustion appliances, i.e. power plants, furnaces, boilers, water heaters etc. the less 2nd Law Thermodynamics “exergy efficiency” the system becomes (a bad thing) – it’s the greatest paradox of the 21st century...and an example of when two rights make a wrong. You will learn how to use hydronics to enable both eNergy and eXergy efficiency by understanding the relationships between building and architectural systems with mechanical and energy systems.

Workshop seminar #3:  Hybrid: Integrating Ventilation, Dehumidification & Cooling with Hydronics

Why is it that a large percentage of the industry recommends against hydronics because it forces owners to purchase a ventilation equipment and ducting independent of the heating and cooling system; and yet when stating preferences most renowned ventilation experts agree separate independent ventilation systems are best? Go figure? Learn why hydronic chilled and heated water systems integrate and enable the best of both worlds – thermal comfort quality and indoor air quality.

Learning Objectives:

1. Students will be able to describe the first principles of thermal comfort.
2. Students will gain an understanding of the design and costing for complex to simple systems.
3. Students will gain an understanding of why hydronic based systems are a logical choice for efficiently converting and moving energy throughout a building.
4. Students will be able to describe the hydraulic principles found within hydronic systems.

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.
