Filling out Space Usage Type
When filling out template PI form 3 "Occupant and Usage Data" Table Plf3-1 Space Usage Type:
1. How much break-out should be provided for Regularly Occupied 'Support' Spaces that are ancillary to main use type? (Ex. Offices within a Classroom Building, or a bookstore in a classroom building)
2. Circulation is listed as a space usage type in the pull down menu. Shouldn't this be considered "Non-regularly occupied support spaces"?

Can't select "other" in space usage type drop down
I am trying to pick the "other" category to add areas like restrooms/mechanical/kitchen/store etc. in "space usage type" dropdown but when i pick it, the box shows up blank, doesnt show other in it and the form says I am not compliant. has anyone else had any issue with this? Am I supposed to pick any other category for these spaces?
hi Shivani - I believe when you select the "other" category, you then need to type a description in the "space usage type" box.
hope that helps.
Regularly Occupied Space in Core & Shell for office buildings
Are bathrooms, stairwells, and corridors considered a regularly occupied space for a LEED Core & Shell office building?
I'm not looking at the form right now, but in general those spaces are not considered regularly occupied - bathrooms are usually ancillary and stairs and corridors would be circulation. See Cara's comments below on the flexibility of the definitions.
Regularly Occupied Area vs. Unconditioned Area
In filling out the Space Usage Type table on PI f3 I've noticed the form doesn't seem to 'like' when your regulalry occupied area is equal to your unconditioned area. For our particular instance, there is a warehouse portion that is regulalry occupied but is not air conditioned. There are exhaust fans only. In this case the occupied floor area is equal to the amount of unconditioned area, but when both those fields are completed with the same number (slightly less than the gross area) the template does not indicate it's complete.
How does one document that there is occuped but unconditioned space without receiving the red text under the table that reads "Total gross area for each row must be equal to or greater than the regularly occupied and unconditioned areas." preventing template completion?
Clarice, this sounds like a malfunction of the form. I would make sure you have the latest version of the form, and/or contact GBCI for assistance.
PI Form 3 - Daily Occupancy
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 FTEFull-time equivalent (FTE) represents a regular building occupant who spends 8 hours a day (40 hours a week) in the project building. Part-time or overtime occupants have FTE values based on their hours per day divided by 8 (or hours per week divided by 40). Transient Occupants can be reported as either daily totals or as part of the FTE. Residential occupancy should be estimated based on the number and size of units. Core and Shell projects should refer to the default occupancy table in the Reference Guide appendix. All occupant assumptions must be consistent across all credits in all categories. 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:

filling out the space usage type table
So, the point of this table is to orient the reviewer of the project - to give them a good overview of the space types within the building. There are a few credits where space types matter - such as daylighting for schools - and you should be careful to separate out spaces that will pertain to those prereqs/credits. Otherwise, you should just use your best judgement in painting an accurate picture for the reviewer without over-burdening yourself by calling out too many rooms that could be grouped together.
In response to the second question about circulation space, those can be considered ancillary/non-regularly occupied or not - we allowed for flexibility here.
Do you mean that not every room has to be listed?
i.e. We are certifying an Elementary School: should we group all the classrooms and their ancillary spaces (closets, toilets.) and combine them into a signle line in the form?
If that is tha case, what do we do with rooms such as Gymnasiums, Kitchens, Cafeterias, Conference Rooms, etc.? Neither they seem to fall under the broad "classroom" category nor is there a proper usage type under which these spaces qualify for. How about storage or mechanical rooms that are not ancillary to any specific function but to the whole building? there are any options for these, nevetheless every building has this type of rooms.
Donna,
There are probably many different ways you could fill out Table PIf3-1 "Space Usage Type" and have it work properly, and just as many that would not work. You don't need to list every room, but the total square footage for certain space types need to show up in the proper *column* of the table for certain credit forms to work. Here are some suggestions for what might work or not:
If you are pursuing EQc8 Daylight and Views, one key to making it work is to treat the 6th column titled "Regularly Occupied Gross Area (sf)" as the NET, not gross square footageSum of the floor areas of the spaces within the building including basements, mezzanine and intermediate-floored tiers, and penthouses with headroom height of 7.5 ft or greater. It is measured from the exterior faces of exterior walls or from the centerline of walls separating buildings, but excluding covered walkways, open roofed-over areas, porches and similar spaces, pipe trenches, exterior terraces or steps, chimneys, roof overhangs, and similar features. of the regularly occupied spacesRegularly occupied spaces are areas where one or more individuals normally spend time (more than one hour per person per day on average) seated or standing as they work, study, or perform other focused activities inside a building. for that row: actual floor area of regularly occupied areas where users are expected to need daylight and views. The total of this column gets carried over to the EQc8 forms, and you have to provide daylight for 75% of this "Regularly Occupied Gross [net] Area (sf)."
How you divide your spaces between the rows, and how you account for ancillary support areas isn't critical, as long as the areas for ancillary spaces such as closets, toilet rooms, storage closets, mechanical rooms, corridors, etc, are included in Column 3, "Gross Area (sf)" and *not* in Column 6, "Regularly Occupied Gross Area (sf)."
You'll also need a way to distinguish regularly occupied spaces that should be excluded from daylighting requirements such as a photography darkroom, TV studio, specialized labs, etc. so you might want to put those on their own row so that they get totaled in Column 3 but not in Column 6. (Provide a narrative to explain why these spaces should be excluded - see EQc8.)
Thus, in a school, one possible way you could fill out the table could be:
Use the Space Usage Type "Core Learning Space K-12" for all your rows, but have several rows with different summary descriptions under Column 2 "Space/ Name Description (Optional)." You could have one row to represent all your classrooms, a second to represent all group learning spacesCore learning spaces are spaces for educational activities where the primary functions are teaching and learning and where good speech communication is critical to a student's academic achievement. These spaces include, but are not limited to, classrooms, enclosed or open plan), instructional pods or activity areas, group instruction rooms, conference rooms, libraries, offices, speech clinics, offices used for educational purposes and music rooms for instruction, practice and performance. needing daylight such as cafeteria, gym, kitchen (see the EQc8 forum for discussions on why those are included), another row for the regularly occupied non-daylit spaces like darkrooms, and a last row for administrative spaces such as offices and conference rooms. For non-occupied ancillary spaces, subtract those from the Column 6 "Net" square footage for the appropriate row that they might belong to, but it doesn't matter if a closet is accounted for in row 2 or 3.
Does that all make sense?
Yes, it does make sense.
However, I still think they do not provide enough options under "Space Usage Type" (column 1); I guess I can make it up with a description under column 2.
This will do for now, thank you!
Any luck on the circulation
Any luck on the circulation space question? I'm running into this same problem right now. Perhaps these would only include exit passageways or other areas that must only be used for circulation?
Confusing indeed.
Sarah, I'll check around some more, but I would also encourage you to check with GBCI and post back here what you learn. Hopefully we can all help get an answer to this one.
Project data forms in LEED Online
Tony, I checked around and don't have any tips on your questions. We're not sure exactly what GBCI has in mind here, either.
I would ask GBCI for help, and/or go with what feels to you like the best balance of detail. Sorry not to be of more assistance here, but sometimes LEED Online is just like that!
