[Bldg-sim] Definition of a University Dormitory - Residential or Non-Residential?

[Dónal O'Connor]

Hi all,

Thank you for your responses thus far.

I did a quick calculation of the areas. Total Residential Floor area is approx. 75,000 sq. ft. and total Non-residential  is approx. 50,000 sq. ft. The Non-residential areas include the basement, main floor multi-purpose rooms, lobbies, storage etc, and the common corridors, elec, janitor, lounge/study areas on Floors 2-9.

So if we are in agreement that the Residential areas are to use either System 1 or System 2, the next question is what are the Non-residential areas classified as? From Table G3.1.1A it appears the number of floors take precedence over the floor area, so as the Non-residential area extends over 10 floors, it should be classified as System 7 or System 8. Am I correct in saying that the number of floors takes precedence over the floor area?

Thanks again for your help and guidance.

Cheers

Dónal

Per the exception noted by Mr Dirkes, I would model the Baseline building based on Table G3.1.1A; except with the dorm rooms, modeled them with System 1 or 2.






Here is how I come to this decision:






Since your dormitory building contains some non-residential
space types, you shouldn't use the
building type to determine your Baseline, ie it's no longer truly a residential building typeDorm rooms still fall under the residential space type, so use residential Baseline systems (1 or 2) for those spaces"Other building and space types are considered nonresidential"  This
 statement allows the rest of the building to be modeled per standard baseline (area, # of floors, energy source).





I see the same thought process applies to the mixed-use (commercial/apartments) as well.  With the rise
 of mixed-use commercial building, I'm sure we'll be seeing this type of scenario more often.  I welcome any comments or suggestions.





Thanks,

However…..
The notes in that table clarify as shown below.  I think the notes indicate that Donal’s “predominant” building type is residential.  It sounds as though
 there are some “non-predominant” types as well.  Take a look at G3.1.1’s Exceptions for a description of those.
 
>From 90.1-2007 Table G3.1.1A:
Notes:
Residential
building types include dormitory, hotel, motel, and multifamily. Residential space types include guest rooms, living quarters, private living space, and sleeping quarters. Other
building and space types are considered nonresidential

Sir:


 


If the building is over 5 stories high believe that comes under Non-Residential. Period.

Dear Bldg Sim,



I'm looking for guidance on the definition of a University Dormitory building that I'm modeling under LEED 2009, particularly referencing Table G3.1.1A Baseline HVAC System Types. The building has 9 storeys above grade with an underground basement, with a total
 floor area of approx. 125,000 sq. ft.



The Basement is primarily crawlspace, electrical, mechanical, student storage etc.



The Main Floor consists of a number of multi-purpose rooms, further storage facilities for bicycles, recycling etc, with 1/3 of the main floor plan dedicated to student residences.



The remaining floors, 2 - 9, are student residences with a number of break out/study rooms/lounge areas on each floor.



Is the building classified as "Residential", or is it considered "Nonresidential and More than 5 floors or > 150,000 sq. ft" due to the basement and main floor spaces not being "Residential"? Will I have to model the basement and the main floor separate from
 floors 2-9?



Your help is greatly appreciated.



Cheers



Dónal
