What the IgCC Will Mean for LEED

This week, the International Code Council (ICC) released Public Version 2.0 of the International Green Construction Code (IgCC). For those who may be unfamiliar with the IgCC, in 2009 the ICC launched an initiative to develop a model code for the new and existing commercial building sector that would address green building design and performance. The AIA and ASTM International served as Cooperating Sponsors and played vital roles in the development of the IgCC. Additionally, ASHRAE, IESNA, and USGBC joined….

Is LEED De-Certification One Step Closer to Reality?

With the rollout of LEED version 3 came the LEED 2009 Minimum Program Requirements. MPR #6 requires that “all certified project must commit to sharing with USGBC and/or GBCI all available actual whole-project energy and water usage data for a period of at least 5 year.” This, of course, led to a lot of speculation that USGBC would use the reported performance data to validated (or nullify) LEED certification. However USGBC has always maintained the clear position that LEED certification….

How Performance Metrics Will Change LEED Forever

Since its inception, the LEED rating system has been criticized for its points-based approach to green building that focuses on design intent rather than actual building performance. In fact, in many circles, this was strongly considered to be a potential Achilles’ heel of the blossoming rating system. Case in point: about two and half years ago, the New Buildings Institute (NBI) published a study that now appears to have been a watershed moment in the green building movement. In that….

LEED 2009 Neighborhood Development Primer

On April 29th, USGBC officially launched the latest version of the LEED Rating System. More than eight years since its initial conception and three years following the launch of its pilot program, LEED for Neighborhood Development (or LEED-ND) is finally introduced. The rating system, which USGBC claims is the first national system for neighborhood design, integrates the principles of smart growth, urbanism and green building. The following is a quick primer for those who are unfamiliar with the new system…..

Visualizing the LEED 2009 “Size Gap”

Dan in Real Life (LEED)

Last month, I posted information about a strange LEED “size gap” issue my project team ran into with a project in northern Indianapolis, Indiana. It was a strange and complex issue and I am still wrestling with a little bit. It took a unique circumstance for the “size gap” issue to create a real stalemate. For one, the owner did not wish to make the building’s new addition “physically distinct” per the LEED 2009 Minimum Program Requirements. Rather, the owner….

Can (and Will) USGBC Revoke LEED Certification?

Can (and Will) USGBC Revoke LEED Certification?

By now, LEED project teams are generally familiar with the LEED 2009 Minimum Program Requirements (MPR’s). They’re sort of like the Seven Commandments of LEED Eligibility. To further clarify the MPR’s, USGBC issued the LEED 2009 MPR Supplemental Guidance document. However, what seems to be less frequently acknowledged—much less discussed—is the GBCI LEED Certification Policy Manual (originally published April 27, 2009). The Certification Policy manual, a curiously less refined document from the standpoint of graphic presentation, offers an “overview of….

The LEED 2009 “Size Gap”

For any project to be eligible for LEED certification, it must meet the minimum program requirements (MRP) as approved by the U.S. Green Building Council’s LEED Steering Committee (LSC). The MPR can be accessed at: http://www.usgbc.org/ShowFile.aspx?DocumentID=6715 According to the MPR, new additions to existing buildings may be certified separately and independently from the existing buildings to which they are adjoined, provided that they are physically distinct and each has a unique address or name. Similarly, the existing structure can be….
