TRA Certification International, Inc.

TRA-Green, based in Elkhart, Indiana, exists specifically to verify the energy-efficiency and environmental-friendliness claims made for the various materials and components that go into a modular home. We ensure that these materials and components have the proper certifications to be labeled green. We certify that a manufacturer is "green capable" that their process, materials and components can produce a green assembly. We also verify the green claims of materials and components suppliers. Our Verified Green Building Materials Directory was created to assist the systems-built manufacturer and buyer in finding products they can be certain are green-verified. To this end, we participate in (and follow the standards and specifications of) numerous green-building initiatives - the U.S. Green Building Council (LEED), the NAHB, and others. Backing our efforts are decades of international experience and accreditation in certifying Quality Management Systems, including those with environmental aspects.
