HVAC 360 Podcasts

Welcome to building[x]!

Imagine if you will an online learning center that provides the information that you want, no need, about the built environment.  Wouldn't that be great?! That's what I want this site to become.  Now that may be a bold statement but what's life without a few goals.  So what I plan on doing over the next few months is developing a discipline or two at a time.  The pages of these disciplines will contain information from myself as well as other resources from the internet that I have found worth your while. Enjoy.

HVAC 360 - Episode 072 - Melink - 2014 AHR Expo

This week on HVAC 360 I talk with Jason Taylor from Melink Corporation, who I talked to on the floor of the AHR Expo 2014 in New York City.  Melink was showing off their solution to a common problem in the kitchen hood industry, namely control and energy waste by running the exhaust system when it wasn't necessary.  Hopefully you'll pick up a thing or two about kitchen hoods and if you like the episdoe, share it with a friend.

HVAC 360 - Episode 069 - Commissioning Issues Log

Commissioning Issues Logs are the at the heart of what we do as Commissioning Authorities.  In this episode of HVAC 360, I field this topic in response to a listener question and go through what I think should be part of the issues log, what should and shouldn't be included, and what to due about getting these resolved in a timely fashion so that you can make a profit while not making any enemies.  At the end, I include what I consider to be my secret sauce when it comes to making the most use out of a commissioning issues log.  I hope you enjoy the episode and if you did please past it on to a friend or a collegue.

HVAC 360 - Episode 064 - ICC IAS Commissioning Accreditation

The week on HVAC 360 we have a very hot topic for you and this involves standards that are being proposed by the ICC that effect all of the current commissioning certification programs.  We have Gerry Kettler talking to us today as a member of the ICC committee and also as someone who is heavily involved in the commissioning standards for ASHRAE.  One thing to keep in mind is that this standard is out for public comment until mid-May so get your two cents in and if you think anyone else is interested, forward the show and have them comment as well.  Hope you like this topic, if you do let me know.

HVAC 360 - Episode 045 - OPR and CFR

The week we talk about the OPR or Owner's Project Requirements and the CFR, the Current Facility Requirements.  Ultimately they are two side to the same coin, what a owner needs and wants from their facility.  It is a buildings playbook, how it is intended to be used and operated.  Most people would associate the OPR with being something that is found and required by LEED under the commissioning section.  Although this is true, I feel that this document is more than that.  An OPR is a documented plan on how to meet and exceed an owner's expectations.  Is this not the goal for most service organizations anyway?  Why would you not make this a standard practice on every project regardless of size?  It just makes too much sense to me.  Let me know what you think or if I missed the boat on something.  If you like what you hear pass it on.

HVAC 360 - Episode 020 - Prefunctional Checklists for Building Commissioning

In this episode I talk about prefunctional checklists for building commissioning in relation to ASHRAE Guideline 0 and the PECI documents.  Most commissioning authorities have there own style of checklists but I breakdown the anatomy of these forms to help professionals understand or possibly improve their documents.

If you want more information regarding Portland Energy Conservation, Inc., visit www.PECI.org or visit the Commissioning Resource Center for the forms.

Or for ASHRAE Guideline 0, visit the ASHRAE Bookstore.

HVAC 360 - Episode 018 - Virtual Cx

This week we are talking with Mark Walter, the Founder and Principal at Virtual Cx. His firm provides services to other Building Commissioning Company large and small.  I like the niche that Mark is filling with his company and they are truely one of the most innovative services firms that I have seen in a construction industry where the term "innovative" is rarely seen.

The new Green Standard - ASHRAE 189.1

Dusting off my notes from my January trip to Las Vegas for the ASHRAE Winter Meeting I came across a session with Past ASHRAE President Kent Peterson talking about Standard 189.1.  This is ASHRAE's Green Standard which has recently published it's user manual.

The big news about this standard is that it's written in a codified language, which means that it is enforceable by code officials, and it is meant for high performance buildings.  

Now before I go any futher let's back up two steps so that I can paint a broader picture.  ASHRAE's superstar standard has long been 90.1, which governs the minimum energy code compliance. It too is also written in codified language and has been updated on a three-year cycle (2001, 2004, 2007, 2010).  It wouldn't be stretch to say that this code is the least that an engineer could design to without breaking the law (a little food for thought). But ASHRAE has also been raising the bar on standard 90.1 with each new version.  

Now that we have talked about the minimum bar for all buildings let's move on to the minimum bar set for High Performance Buildings, Standard 189.1.

Today when people think about high performance buildings, they think green, they think LEED.  But the LEED process is no more than a guideline, a "paint-by-numbers" points system that doesn't always get you a high performance building. Enter Standard 189.1.  Those familiar with the LEED guidelines will look at this standard and do a double-take.  They look the same.  But be careful, they may have the same structure and some of the same goals, but the ASHRAE committee that developed this has taken a lot of care in structuring it into an enforceable language. One of the real keys that is in the standard is the requirement for high performance building operation.  Time and time again the operation of a building is reduced to the level of understanding of the building operators, but this standard has taken steps that this cycle is broken.  Specifically the steps include commissioning throughout the design and construction process, owner training that focuses on system operation not just equipment operation, and plans for operation that incorporate benchmarking, useage, and maintenance.

Putting 90.1 and 189.1 together you will see that they are not independent.  As standard 90.1 becomes more stringent so to will 189.1.  With the ultimate goal for standard 189.1 to become the net-zero standard for buildings.

Other tidbits from the session:

- Standard 189.1 now adopted as an optional path of compliance for the new Internation Green Construction Code

- Water comsumption is quickly becoming more of an issue than energy consumption for most buildings.

- Studies of existing buildings showing that US power consumption is leveling off, despite improvements in efficiencies.  This is primarily due to the fact that we are plugging more stuff in.

- Newest version of standard 62.1 (the ventilation standard) is coming out requiring less ventilation.

ASHRAE Winter Meeting 2010 - Day 2

Today was spent attending educational sessions are here some of the nuggets of knowledge that I will pass on to you:

  • ASHRAE 90.1 - 2010 is being reviewed and is slated to exceed the 2004 version in energy savings by 30 percent.  However, preliminary data is coming in that in its current form the standard is saving only 11.4%.  The standards committee is confident that the goal will be reached and that they have a couple of large addenda that may make that possible.
  • On the commissioning front, common places to look for improper operation include economizer operation, hot and chilled water resets, static pressure control, equipment scheduling, and lighting scheduling.  Despite how basic these may sound they are often not set and end up just falling through the cracks.
  • Also on commissioning, when you start your project, and hopefully that's during the design, you might first read through the sequence of operations, then draw a system schematic, and finally graph equipment function interaction.  If you didn't follow me just then let me explain.  First the sequence should make sense, be completely testable, and have the proper set points identified. Next draw the system to help make sure that you understand the system, this will also help with the documentation for your LEED System Manual. Lastly create a graph with the Y-axis labeled 0-100% and the X-axis labeled with operating temperature range.  Now if you graph the sequence of the, say, HW Valve, CW Valve, and OA damper for air-handling units all in different colors you have just made a graphical representation of the sequence that may show scenarios that the written sequences just don't.
  • Here was the thought question of the day: If you are restricted by the architect for mechanical room space because extra square footage is expensive, do you not run the risk of forever increasing the energy inefficiency of the system because of the severe duct and piping transitions?

Now its time to get some sleep and rest my puppies before I go to the AHR Expo tomorrow.
