Marilyn’s Ultimate Green Building Checklist A Green Checklist is essentially a list of building materials and methods that you can incorporate into your project to make it GREEN. Within the past decade, many Green Building Checklists have been created around the world. They have been developed by different government entities, public utilities, non-profit organizations and private entities with the overarching intent to clarify the many ways in which we can design and build GREEN. The most well known and referenced Green Building Checklist in the United States is the Leadership in Energy and Environmental Design (LEED) Guidelines. Architects, builders and even entire government jurisdictions refer to LEED to guide their commercial and municipal building projects. Since the U.S.G.B.C has yet to publish a Green Building Checklist for residential projects, other entities have developed their own. In California, the most respected and frequently referenced Residential Green Building Checklist is that of the Alameda County Waste Management Authority (ACWMA). In combination, the LEED and ACWMA Guidelines represent the definition of green building in California today. But neither LEED nor ACWMA nor any other Green Building Checklist is currently comprehensive—none of them list ALL of the ways in which to build green—until now. Marilyn has created a COMPREHENSIVE Green Building Checklist. This Checklist not only covers the contents of LEED and ACWMA but ALSO INCLUDES ALL of the other green products and practices referenced in other green building Checklists, books, articles and classes. In this way, Marilyn’s Green Building Checklist is the most thorough and up-to-date reference to Green Building today. Moreover, this Checklist is organized according to what “kind” of green the product or practice is. That way, you can search for green building materials/methods based on whether you are most concerned with 1) Improving Health/Comfort 2) Conserving Resources 3) Increasing Energy Efficiency or 4) Respecting the Site and Promoting Community. I hope that this comprehensive Green Building Checklist helps you determine how your project will be GREEN!
