Trenwyth Industries recognizes that “Green Design” involves design and construction practices that significantly reduce or eliminate the negative impact of buildings on the environment and its occupants. The LEED (Leadership in Energy and Environmental Design) Green Building Rating System® evaluates environmental performance from a “whole building” perspective over the lifecycle of the facility.

Because “green” or sustainable design is such an important element in the life of this planet and its inhabitants, Trenwyth is pleased to provide its customers with a wide variety of products that may earn points under the “Materials and Resources” Category of the LEED Green Building Rating System.
