The intent of this White Paper is to address areas of the U.S. Green Building Council's Leadership in Energy & Environmental Design (LEED®) Rating System that are relevant to the use of Decorative Glass. This document describes the ways in which decorative and mirror glass products are consistent with the intent of the LEED Rating System. Although individual building products do not in themselves constitute conformance to the LEED criteria, depending on the amount and type of glass used in a project, this versatile material has great potential to help achieve LEED credits. Also found within is a comparative analysis between LEED® 2009 and LEED® v4.
