Tony Schmitz, vice president and senior project manager at Dallas-based Hoefer Welker, has been leading the architecture and design firm’s sustainability initiatives across all sectors. With an academic foundation in environmental design, Schmitz has most recently taken his green building and design expertise to Collin College, in McKinney, Texas.
Sustainability features of the up-and-coming campus include improvements in the areas of water conservation, design strategies and efficient technologies.
At Collin College, Schmitz has made strides in the area of resource use reduction, primarily for water. As our most precious natural resource, water usage has recently come under scrutiny in the city of Dallas, where the city council unanimously passed the 2019 Water Conservation Plan. All of Schmitz’s projects have achieved or surpassed their goal of 40 percent water reduction for the last five years. This figure has become a standard for Schmitz, with a goal to increase to 50 percent water reduction and 100 percent for non-potable water reduction.
