2020-05-07 Kick-off Session
The following files support the session this morning. I believe the file names are self explanatory, but let me know if you have questions. The cooling tower model we were using is not on the site yet, so I have provided that below if you want to play with it. But the chilled water plant model on the site is current and can be found on the Chilled Water Plant Scoping Exercise and on the Chilled Water Plant System Diagram Exercise page. If you want to try your hand at the "Easter Egg Hunt", you will find everything you need on the Bureaucratic Affairs Building Scavenger Hunt page.
Finally, if you want to read the Energy Conservation is an Ethic paper that I mentioned, you will find it along with other very useful things that Bill Coad wrote on the Bill Coad's Writings page of the website.

The zip file contains the files I used in this morning's session. There is a supporting information folder that includes the mixed air temperature calculation spreadsheet I used (also available on the Mixed Air Calculations tool page of the website), the spreadsheet with the ball room load calculation in it and the ASHRAE cooling load temperature differential (CLTD) tables in it, which can be used to do a manual, hour by hour load estimate.

Note that the PowerPoint slides have slides that show the calculations we did in class in case you are interested. We were going pretty quickly at the time.
In addition, an number of resources for doing piping calculations were mentioned. They included:
