The following is an update on where USGBC stands on recognizing multi-attribute product sustainability standards and certification programs, such as Green Squared®, for point contributions in LEED®.

A couple of weeks ago, the National Association of Homebuilders (NAHB) released draft revisions to the 2008 National Green Building Standard (NGBS). This document is out for public comment until June 11, 2012. The next version (2012) of this standard is expected to be finalized and published by the close of the year.

Tile is fired at very high temperatures, usually in excess of 2,000°F. At such high temperatures, any organics that might be present in clays or binders are completely burned away. As a result, the final product is inert and has no VOCs that can be emitted.

The standard on which the Green Squared® certification program is based, ANSI A138.1, is divided into five sections, the first of which was reviewed in our last blog entry. The second section, Environmental Product Manufacturing and Raw Material Extraction, standardizes sustainable production practices.

The standard on which the Green Squared® certification program is based, ANSI A138.1, is divided into five sections. The first section, Environmental Product Characteristics, standardizes sustainable attributes such as the amount of recycled content, level of volatile organic emissions, amount of indigenous raw materials, etc.
