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

[Morgan Heater]

Those are support spaces for the residential and can just be the same
system type, as that’s the predominant space type.  Anything else is
needlessly complicated.  The enclosed document is useful for establishing
modeling inputs for residential projects.

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 type
*	Dorm 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
