Welcome to the Department of Sustainable Technology and the Built Environment web site, where you can learn more about one of the most dynamic departments on campus! We encourage you to join our more than 500 majors and to work with some of the most outstanding faculty in the nation in the fields of sustainable technology and building science.

The Department of Sustainable Technology and the Built Environment offers degree programs in Sustainable Technology (emphasizing renewable energy and other "appropriate" technologies) and Building Science (with concentrations in Construction Management,  Architectural Design & Technology, and Sustainable Building Systems). Our Graduate Program offers a Master of Science in Technology degree, with concentrations in Appropriate Technology, Building Science, Sustainable Design and Construction, and Renewable Energy Engineering.

Department of Sustainable Technology and the Built Environment faculty and staff are dedicated to:

  • Enhancing students' problem-solving abilities through laboratory and studio-based experiences that feature hands-on activities.
  • Teaching students to examine current and emerging technologies critically, with the goal of improved technological designs for a more sustainable future.
  • Preparing students for careers and, where relevant, professional certification or licensure.
  • Helping students to become informed consumers and responsible citizens.
  • Encouraging students to establish professional and personal goals and ethics to guide practice.
  • Inspiring students to pursue lifelong learning.

We hope you'll consider becoming a part of the Department of Sustainable Technology and the Built Environment at ASU!
