2014 NEBB Annual Conference Presentations, Friday, April 4, 2014

 

The recession is supposed to be officially over, but given the size of the 18- to-34-year-old cohort and the shortage of "real" jobs out there, it may just be the beginning for the lost generation. Without some creative new ideas, the long-term outlook is bleak; but this generation will only be "lost" if it does not find its way to a new approach.

• Explore how the construction industry provides both long- and short-term solutions for this potentially "lost generation", and how it needs them to survive.
• Understand why we need to let go of the old ideas about career progression
• Learn how a college education fits in and look at the new paradigm this last recession allowed us to discover

Get to know the simple math that allows the balancer to calculate and visualize the system problems, especially when they’re not that easy to see!

Learn how using some basic math (+,‐,•/•), a spreadsheet and an old calculation technique can help you model and simulate what will happen in a hydronic system and how it can be applied to the field to help understand simple and complex balancing problems. Review of some of the core hydronic system fundamentals to drive home the techniques. When you’re trying to deliver performance, it doesn’t hurt to have a few extra mathematical tools and techniques in the toolbox to prove your point!

Download the presentation to understand System Curve(s) Application beyond a curve plotted on a pump curve and how to develop a simple method of using a spreadsheet to calculate an expected outcome.

Data Centers exist to provide the environment for IT assets to support the current and future needs of business. To meet this need, planning and follow through are essential, starting from the conceptual design phase through to commissioning. This panel features data center design & planning and commissioning expertise on a range of data center sizes, efficiencies and types. The presenters discussed a range of topics from first and life cycle cost decisions, how IT groups work with designers for internal and external requirements, and best practices to consider adopting. Collaboration and knowledge sharing is required in companies to manage capacity, and this is a unique opportunity to hear a topic that are essential for future data center services.

ASHRAE Guideline 0 claims 1982 as the birth of the formal commissioning process. Over 30 years later, commissioning of HVAC systems for commercial buildings is a common and accepted practice with well understood benefits. Meanwhile, the commissioning concept is still in its infancy for the commercial refrigeration industry and nearly rejected by the industrial refrigeration community. This presentation, by a practicing refrigeration engineer with a toe in the HVAC industry, seeks to explore the roadblocks being established by the refrigeration industry to full scale commissioning. Some will be excuses familiar to seasoned commissioning veterans. Others are valid grievances to shoehorning refrigeration systems, with their often unique purpose and design, into the rigid framework of commissioning. Finally, parallels were drawn between the commissioning and regulatory processes already being implemented by the refrigeration industry.

Understanding the Selection and Application of Hydronic Systems Control Valves
For whatever reason, application of control valves for heating and cooling hydronic systems can mystify and confuse HVAC system designers, but the valves proper selection is the difference between economical and comfortable system operation and uncomfortable inefficient systems. This seminar will take a systems approach to proper valve selection and operation, and how various piping and pumping designs and system components effect valve and control system performance.
 
Learning objectives:
• Understand Relationships of Applied Heat Transfer and Control.
• Be able to calculate system hydraulic effects on control and balance valve operation.
• Hydraulically appreciate how balancing of the system can be done and the performance effects, including "diverse" systems.
• Understanding HVAC control and balance valve types.
• Develop understanding of how hydronic system organization can maximize or minimize system performance and optimization.
• Practical variable speed pump and valve interaction; How you set the pump differential pressure set point.

Expedient and user friendly energy benchmarking, the first step in a successful Retro-commissioning (RCx) project is elusive. Establishing the baselines, developing the reporting, automating the utility inputs adds to accuracy, adds to the project quality and helps define results during the retro-commissioning process. Building Automation System (BAS) data mining is the key to thorough, accurate and expedient control system evaluation. The days of manual interrogation of the BAS are gone. The days of building cumbersome, system clogging trends in BAS systems are gone. The systems are simply too large and complex for this laborious, error prone process. Systems and tools that allow the RCx team to view the BAS holistically and query it for exceptions can deliver RCx results and solutions faster, with more accuracy.

This presentation covers the above components in the context of the NEBB Retro-commissioning process. The presentation includes examples of both processes and will include a live data mining session on a current project.

The quest for finding a suitable, eco-friendly replacement gas for Sulfur hexafluoride (SF6) as a tracer gas has been a top priority for NEBB and ASHRAE. This lecture will discuss a number of options; the good and bad points of each, and overall effect on the global environment.

• One of the options submitted for study, Nitrous oxide, N2O, although relatively stable, has been found to have many weaknesses; such as, being a greenhouse gas, an illegal recreational drug, chemical reactivity with CO2, and issues noted during CFD modeling in FHT

• Another option presently be investigated is heptafluoropropane or HFP. An unlikely sounding alternative, HFP, also known as FM200, has been tested and used by the US Navy and data communication companies as a fire suppressant and replacement for halon.

Learn about current updates in tracer gas, sustainability implications and updates on CFD modeling as well as computational and practical testing protocols to analyze the efficiency and practicality of tracer gas.

Glass media for HEPA filters has remained nearly unchanged since it’s origin in the 1940’s. Gore-Tex HEPA media was introduced in the mid- 1990’s. Initial cost and high resistance were issues. This indestructible media continues to evolve. Daikin Industries made significant improvements early this century, but there were challenges for in-situ integrity testing. Now there is a new generation of ePTFE filter media that can be tested using traditional oils and test equipment.

A qualified ePTFE certifier program is underway to assure older generation of ePTFE is tested properly. The program offers training in the use of modern test equipment for testing modern test filters.

Concern for a sustainable future has motivated change in the building industry. Consequently the industry's mechanical system staple, the variable air volume (VAV) system, is giving ground due to ventilation and humidity control performance deficiencies. In this presentation, a case will be made that a dedicated outdoor air system (DOAS) currently offers the best solution to VAV deficiencies. Since a DOAS requires parallel space sensible cooling equipment, a plethora of cooling technologies are competing for that role with DOAS as VAV is being displaced. One of the leading technologies, active chilled beams, was  discussed in some detail.
