(not shown) Current Building Science Group Students
The Group attempts to reduce the current compartmentalization of decisions in building practice, by looking at buildings throughout their lifecycle in an integrated way. Compartmentalization occurs temporally throughout the building process, from initial design through delivery and commissioning. It occurs professionally, with architects, engineers, builders and operators performing their functions in sequence and with minimal feedback. It occurs conceptually, with discipline-based knowledge from research often ill-presented for the purposes of application and practice. Since buildings are a natural mix of disciplines, professions, and physical processes, the greatest promise in providing better buildings may be to create a cross-disciplinary appreciation of the fundamentals that make buildings work. We attempt this in our teaching both on campus and to professionals, and in targeting our research results to both architectural and engineering audiences. The Group has a strong interest in building science education. Many of our graduates have gone on to teach in other universities. The Group has made considerable efforts to improve curriculum materials used in teaching both here and elsewhere. Professor Arens was a co-founder in 1983 of the Society for Building Science Educators (SBSE), the only organization of its type in the U.S. with approximately 120 members internationally, and Professors Benton and Brager have served as Presidents of SBSE.
