Campus and Multiple Buildings Approach

I recently became the LEED adminstrator for a project that includes multiple buildings, construction phases, and contractors.  The project has been divided into two has two registrations under NC 2.2.  I am still trying to get my head around how this will work and could use some advice.  The central building and a recently added auxillary building (each with separate mechanical/electical systems but connected structurally) has one registration.  These two buildings will be constructed by two separate contractors.  The second registration is for 5 office buildings that all have the same design but are situated around the central building and are structurally connected to this central building but each have their own mechanical/electrical systems.  These five buildings will be built in two phases but probably by the same contractor.  Here are my questions:

  • Can both LEED projects share the same LEED project area?  Therefore utilizing the campus approach.  The alternative would be a leed boundary that is a circle and another that resembles a donut.
  • Can the second project utilize the multiple buildings approach since they share the same design exactly but obviously have different orientations?
  • Is there a timeframe for certification of the second project if there is a significant delay between phase 1 and phase 2 for the office building registration.

Thanks for any suggestions/guidance.

Multiple Building HVAC system

Project Location: Argentina

We have two buildings in the same Project boundary, as farFloor-area ratio is the density of nonresidential land use, exclusive of parking, measured as the total nonresidential building floor area divided by the total buildable land area available for nonresidential structures. For example, on a site with 10,000 square feet (930 square meters) of buildable land area, an FAR of 1.0 would be 10,000 square feet (930 square meters) of building floor area. On the same site, an FAR of 1.5 would be 15,000 square feet (1395 square meters), an FAR of 2.0 would be 20,000 square feet (1860 square meters), and an FAR of 0.5 would be 5,000 square feet (465 square meters). as I understand, this would be a Group Building Certification.
The HVAC system will be variuous VRF systems, each for each floor of each building.
The thing is that some of the outside units of the highest building will be placed on the roof of the smallest building.
Do we have it to consider as "campus providing"?, or would it be ok if we assign each building with its own energy consumption regardless of where it is located?
I have to highlight that both buildings are in the same Project boundary.
Thank you

Aggregate vs. lowest performing

Project Location: United States

I have seen a reply on the forums from Eric Anderson claiming that the LEED Guide to Campus and Group approach is incorrect in stating that the Lowest performing building will be counted in a number of energy credits. His claim is that you will actually get the aggregate. can this be confirmed or refuted? I am in a struggle with Several large projects trying to decide between A) individual registrations and tangling with dividing out documentation details for Construction credits B) using campus approach; C) using Group Approach.

don't know if you ever got a response, but "yes", Eric is correct. We had a Group project and the energy performance (EAp2, EAc1, etc) was aggregated.

The Guide is not as clear as we would like regarding this issue.

Re: Campus and Multiple Buildings Approach

You may find pages 4 - 7 of the Application Guide for Multiple Buildings and Campuses relevant here.

Note that on
the USGBC is recommending projects wait for the anticpated update to the Application Guide in Fall 2010 before submitting.

Part 2 - hit enter too soon:
If the buildings are all under the same ownership, it sounds like all the projects could be treated as a single campus project.
The three different scenarios defined on page 5 will determine how the LEED Boundary is defined. It may be one site boundary is shared by all projects, or it could use different LEED boundaries for each building.
Although the boundary definition is an important one to nail down, it shouldn't constrain you too much either way, since the AGMBC lets many credits refer to shared resources such as parking, stormwater management, open space, etc, whether or not they are within the individual building's defined boundary.
