Gross floor area modification

Project Location: Guatemala

Hi

If a project size is modified (the gross floor areaGross floor area (based on ASHRAE definition) is the sum of the floor areas of the spaces within the building, including basements, mezzanine and intermediate‐floored tiers, and penthouses wi th headroom height of 7.5 ft (2.2 meters) or greater. Measurements m ust be taken from the exterior 39 faces of exterior walls OR from the centerline of walls separating buildings, OR (for LEED CI certifying spaces) from the centerline of walls separating spaces. Excludes non‐en closed (or non‐enclosable) roofed‐over areas such as exterior covered walkways, porches, terraces or steps, roof overhangs, and similar features. Excludes air shafts, pipe trenches, and chimneys. Excludes floor area dedicated to the parking and circulation of motor vehicles. ( Note that while excluded features may not be part of the gross floor area, and therefore technically not a part of the LEED project building, they may still be required to be a part of the overall LEED project and subject to MPRs, prerequisites, and credits.)) after the preliminary review, besides of the credits that have been attempted what other consequences do I have to consider?

Thanks

Carlos—I agree with Summer’s recommendation below (http://www.leeduser.com/comment/redirect/71714) to seek guidance from your GBCIThe Green Building Certification Institute (GBCI) manages Leadership in Energy and Environmental Design (LEED) building certification and professional accreditation processes. It was established in 2008 with support from the U.S. Green Building Council (USGBC). review team. You will be expected to update all documentation affected by the change in floor area to ensure that the floor area is consistent across all credits. This may include energy models, MRp1 waste calculations, and any other credit calculations that use the gross floor areaGross floor area (based on ASHRAE definition) is the sum of the floor areas of the spaces within the building, including basements, mezzanine and intermediate‐floored tiers, and penthouses wi th headroom height of 7.5 ft (2.2 meters) or greater.

PI Form 2, Square Footage of All Parking Areas

Project Location: United States

If a project has a multi-level parking structure, does the area on the upper levels get counted, or is this simply a ground plane calculation?

Building area to site area ratio

Project Location: Italy

Hi, I am doing an office tower (19 stories above grade).
The gross floor areaGross floor area (based on ASHRAE definition) is the sum of the floor areas of the spaces within the building, including basements, mezzanine and intermediate‐floored tiers, and penthouses wi th headroom height of 7.5 ft (2.2 meters) or greater. Measurements m ust be taken from the exterior 39 faces of exterior walls OR from the centerline of walls separating buildings, OR (for LEED CI certifying spaces) from the centerline of walls separating spaces. Excludes non‐en closed (or non‐enclosable) roofed‐over areas such as exterior covered walkways, porches, terraces or steps, roof overhangs, and similar features. Excludes air shafts, pipe trenches, and chimneys. Excludes floor area dedicated to the parking and circulation of motor vehicles. ( Note that while excluded features may not be part of the gross floor area, and therefore technically not a part of the LEED project building, they may still be required to be a part of the overall LEED project and subject to MPRs, prerequisites, and credits.) is 280000 sf, with a Total site area within the LEED project boundary of 30000 sf and a 15000 sf as footprint of the project site.
I have to verify the Building area to site area ratio calculation.
Is it right to have a value as 933%?
Thank you.

LEED site definition

Hi, I am doing an office tower which locates on a podium together with another tower. I just choose the total building site as the LEED site. But after submitted for the pre-certification, the response said that the site shouldn't includes the podium and the other tower, in addition to the office tower that is pursuing certification. So I dont know how to set the LEED boundary. Shall I just set the boundary which only has the office building in it? Thanks a lot!

Hi Jie. Maybe these definitions from the MPR Supplemental Guidance Revision #2, Last Updated: September 1, 2011 (http://www.usgbc.org/resources/leed-2009-mpr-supplemental-guidance-revis...) can help:
-LEED Project: All real property within the LEED project boundary, including the building(s) or space(s), all structures, land, etc. which collectively are attempting or have earned certification.
-LEED Project Boundary: The line that indicates the limits of the real property for which the project team is attempting or has earned certification.
-LEED Project Building: The structure which is attempting or has earned certification.
It seems that you have a vertically attached case (i.e. a certifying tower on top of a non-certifying podium). You can retort to the explanation under the "BUILDINGS ATTACHED TO NON-LEED CERTIFIED BUILDINGS" section on page 17 of the stated Supplemental Guidance document.

Total Gross Area: does the roof area counts?

When calculating the "Total Project Building Gross Area" required by the PI form 2: does the roof areaRoof area is the area of the uppermost surface of the building which covers enclosed Gross Floor Area, as measured when projected onto a flat, horizontal surface (i.e. as seen in Roof Plan view). ‘Roofs’, or portions of roofs, covering unenclosed areas (e.g. roofs over porches and open covered parking structures) are not included in the areas used to evaluate compliance with SSc7.2, though they may be applicable to SSc7.1. level counts? My project has a flat roof accessible only for plants maintainance.

thank you

Thanks Jens. Does it means that if I have an enclosed space on the roof (e.g. the MEP rooms, having their own roof and walls) it has to be included within the calculation of the gross floor areaGross floor area (based on ASHRAE definition) is the sum of the floor areas of the spaces within the building, including basements, mezzanine and intermediate‐floored tiers, and penthouses wi th headroom height of 7.5 ft (2.2 meters) or greater.

Excludes air shafts, pipe trenches, and chimneys. Excludes floor area dedicated to the parking and circulation of motor vehicles. ( Note that while excluded features may not be part of the gross floor area, and therefore technically not a part of the LEED project building, they may still be required to be a part of the overall LEED project and subject to MPRs, prerequisites, and credits.) for PIform2 ?

I would alert your GBCIThe Green Building Certification Institute (GBCI) manages Leadership in Energy and Environmental Design (LEED) building certification and professional accreditation processes. It was established in 2008 with support from the U.S. Green Building Council (USGBC). review team as to the circumstances of the project size modification and ask for project specific guidance. This can be done through the Help tab at LEEDonline.
