Dr.-Ing. Wolfram Trinius studied engineering, and published his Dissertation entitled “Life Cycle Assessment in Construction” in 1999 at the Technical University of Stockholm (KTH). He founded the engineering firm Trinius in Hamburg in 2000, where he carries out consulting, research and development projects, as well as the development of standards related to sustainable building. He is academically engaged at the University of Gävle (HIG) in Sweden, and has represented Sweden in international committees dealing with sustainable building. The ISO Standards ISO 15686-6 (Service Life Planning of Buildings and Constructed Assets) and ISO 15392 (General Principles of Sustainability in Building Construction) were developed under his leadership. Through his collaboration in numerous international research projects he has established a broad portfolio of experience encompassing life cycle assessment, environmental product declarations, performance-based building, service life, and life cycle costs. Innovative sustainable building is also the focus of two EU research projects in which Dr. Trinius is playing a leading role: “STAND-INN”, which involves the integration of sustainability aspects into BIM Communication Standards (IFC/BuildingSMART) and which won the Europe-Innova Award for “Best Network 2008”, and “Smart-ECO”, which is investigating the potential contribution of innovative solutions and systems to the vision of sustainable building.
The work of Trinius Engineering in these exciting areas bridging innovation and sustainability, as well as its extensive experience with Swedish and international environmental assessment methods led the firm to become a co-founder of the DGNB, where Dr. Trinius is currently active in system development, on the Technical Committee, and as an Auditor, Education Program Instructor, and Conformity Inspector. He is furthermore a founding member of the Austrian Sustainable Building Council (ÖGNI), and his involvement in its Technical Committee further underscores his international credentials in the area of system development for certification systems. Dr. Trinius’ longstanding international engagement was highlighted again by his recent appointment as independent inspector of environmental product declarations under the IBU System.
