Existing Building Commissioning Workshop Series 17 Materials

As indicated on the main page, the true source for the materials for the existing building commissioning class workshop is the FTP site Ryan maintains.  If you need information regarding how to access it, you should contact him via e-mail at R2S2@pge.com.  It would be desirable to include the words "EBCx Workshop Series Materials FTP Site Access" in the subject line to catch his attention.
 
​The materials below are the materials I provide for the portions of the workshop that I teach.   I am going to keep placing them here so that you can access them before class if you want and also to make it easy for Ryan to pull them back for the FTP site. 

Note that most of the time, I include a "READ ME" file in the zip file with the materials and resources that describes what each of the files is about.

FOLLOW UP

I will be placing any follow up information here with a week after the class.

.This is the average daily consumption analysis tool that is no longer available online because the California Commissioning Collaborative's website no longer exists.   You will find a paper titled Using Utility Bills and Average Daily Energy Consumption to Target Commissioning Efforts and Track Building Performance on the Materials from Classes and Presentations  ICEBO page if the website that describes the concepts behind the tool

For those who want a little SketchUp familiarization tutorial, we are offering two informal 30 minute web training sessions.  Here are the links to them:

• Wednesday, June 30, 2021 at 6:00 PM Pacific Time - Click here to join the meeting
  
• Thursday, July 1, 2021 at 12:00 Noon -  Click here to join the meeting

There are also recordings from the sessions last year that you could review on the SketchUp Resources page at this location:

I mentioned in class that the folks at CERL had shared a "cheat sheet" they made to guide folks to common EBCx opportunities when they were scoping a project and they have generously shared it with us.  I have put that on a new Scoping Resources page I created on the website that also includes a couple of other resources that may be helpful for you as you benchmark your facilities, do the average daily consumption analysis, and start your scoping process.

In the course of our discussions, we talked about Triple Duty Valves (TDV) several times.  The image to the left below shows how you go about reading one.  The images in the center and to the right show what one looks like inside.  Note how there is only one valve seat, meaning that when it wears out, unless there is another isolation valve upstream of the TDV, you will need to schedule a system outage to make the repair.

 

We also looked at a (very scary looking" pressure-enthalpy diagram (ph diagram) and I mentioned a resource that would make it much less scary.  That resource is the file below.

Finally, our outreach seems to be spreading and we now find ourselves with students from different countries;  countries where the engineering units are the SI system instead of the British system we are accustomed to.  Ryan and I are thinking about how to address that, but as a starting point, I wanted to point out that Excel has a function called CONVERT.  I think you can take a formula and put it inside the CONVERT function and it will change the units.  The trick is remembering the units codes.  This link explains it a bit.

I plan to experiment with it a bit and we will include some sort of demonstration as a part of our next class.
