Green Building Through Integrated Design

Chapter 5: Barriers to High-Performance Buildings Why Some Projects Succeed and Others Fail

Overview

Let s take a short pause and look at what might influence the successful undertaking of a LEED project. As of June 2008, there were more than 53,000 LEED Accredited Professionals (APs), so one would expect that the success rate (defined as eventual certification of a LEED registered project) would be increasing over time. It s hard to say, because there were still only about 1170 LEED-NC and LEED-CS certified projects, as of June 2008. That means that most LEED APs have yet to complete their first LEED-certified project and therefore have little hands on experience with the entire process, from start to finish. And, as many professionals know, design and construction projects are messy affairs, often with significant obstacles in the way of realizing the initial intentions of the owners and designers. Nonetheless, buildings do get built and occupied eventually. This book demonstrates a process that works for high-performing (LEED Platinum) projects and shows you how to apply this same process to your own projects.

As of June 2008, there were nearly 7200 LEED-NC projects registered for eventual certification, and slightly less than 1100 certified projects, about 15 percent of the total registrations. In all other rating systems, there were 4060 projects registered, and 435 certified, less than 11 percent. Look at the numbers in Table 5.1, comparing registered versus certified LEED-NC projects to date. [*]
