I am having trouble with the transient numbers here. Our average transient number is 295 per day, while the peak transient number is 46 at the peak time. I assume I need to change the average transient number to a per hour value to satisfy the table requirement ("peak occupancy greater than or equal to average"). Is this correct for this table?
The confusion is that when this relates to other credits. For SSc4.2 - it makes sense to use the 46 peak time transients during the peak period to determine the number of bike racks. For WEp1, we have the option to use either an FTE or total daily occupancy. But if I enter 295 for the total daily occupancy in the table for PIf3 (to stay consistent), it doesn't satisfy the formula.
So can anybody confirm that the Transient Values should be an FTE value and not a daily value?
Also, what does the asterisks next to the "Typical Peak" title (under the "Average/Peak Text" column) refer to?

Ray -
Which rating system are you using? When I look at one of our projects under NC 2009, PI Form 3, Tables PIf3-2 and PIf3-3 I don't see the same titles or the astericks you mention in your last paragraph. Also check which form version you have - whether it's a Beta form or later version listed at the bottom of the form page. You may need to download an updated form if there's been an updated one since you started.
My understanding of table PIf3-3 Total Daily Occupancy is that "Peak" transients is the highest number of transients in the building at any one regular time, say lunch hour, which in your case sounds like 46. In my form I can enter either 295 or a lower number in the Daily Average field without seeing an error message.
It may be the Daily Average field for transients is asking for the average number of transients in the building at any typical time (less than 46 in your case), not the total number per day (295 in your case). If you use a lower number does that make the WEp1 form work as expected?
You'll probably want to ask the GBCI via online feedback form what the correct value is to enter- total transients for the day, or average at any point - since I'm not 100% clear of the intent of the form here.

Ray, did you ever get more clarification on the issue of whether the "Daily Average" number should be the total transients for the entire day? I'm working on a university classroom/lab building and I'm not sure what to enter for the daily average.
If anyone else has advice for completing this table for transients I would greatly appreciate it. Thanks!

NC 2009, PI form 3 BETA, Daily Occupancy Table has the Typical Peak* and no explanation of the *
I am curious what the * is indicating.

Tyra,I do not know what the * is indicating. I would suggest updating your form though, since you're still using BETA. I believe that form is now in v4. To do this back up your data then contact GBCI through the feedback form requesting the update for this credit. The newer version of the form should be clearer.

Thank you, Emily.
I'll request the upgrade the new forms are quite different.
This is the response I received to my initial query:
Response:
It is recommended to upgrade all forms to latest available version and you can just send one feedback for all forms.
Please review the upgrade process as mentioned below. After you decide to upgrade, please save a copy of the existing form and then please send us a ‘feedback’ from LEEDONLINE indicating (1) form has been saved and that you have (2) read all the points for the upgrade and consent to the upgrade.
Please note the following, before you upgrade forms:
1. Please check new version sample forms within “Forms Update” on home page or click on “Sample Forms Download” link after you log in.
2. In most cases, the majority of data already entered in the form will be retained. However, some data loss might occur, and if the upgrade includes new fields, new information may be required. Therefore, after the upgrade is complete, it is important that you check all upgraded forms for completeness and accuracy (please refer to help link https://www.leedonline.com/irj/go/km/docs/documents/usgbc/leed/config/co... for more details regarding “LOv3 Form Updates”)
3. At any point of time we cannot downgrade form version once updated.
Please let us know if you have further questions or feedback.
You may contact us thru the ‘feedback’ button on LEED ONLINE or call us on the ‘hotline’ at 1-800-795-1747 and (9am -5:30 pm EST).
