The first edition of this book was calibrated to the LEED green rating system, but that system, while popular and created with the highest of good intentions, has serious drawbacks, including the fact that achieving a rating on a building tends to be slow, complex, and expensive. It is also still easy to get a high rating on a building located in a very unsustainable place.

The Original Green Scorecard, by contrast, is meant to be fast, friendly, and nearly free. It is also appropriate to the region, to the version used in this book is calibrated to The Bahamas.

LEED is built almost entirely on Gizmo Green, which is the proposition that with better equipment and better materials, we can achieve sustainability. While efficiency is a part of frugality, Gizmo Green misses most of what true sustainability is really about. As a result, the previous edition of this book was only able to tag some patterns as sustainability patterns. If you compare this edition to that edition, it’s clear that far more patterns show up as sustainability patterns using the Original Green Scorecard, highlighting how the architecture of The Bahamas is attuned so wonderfully to its place. The Original Green Scorecard is being rolled out for the first time for this book, with the hope and intent that The Bahamas become an international model of sustainability.

Primary & Secondary Credits

The four foundations of lovable, durable, adaptable, and frugal buildings are primary to the Building Scorecard. But buildings can also contribute to places that are nourishable, accessible, serviceable, and securable, which are secondary credits of the Building Scorecard. The credits are organized by foundation, category, and subcategory as follows:
