In this role, he established a research lab focused on passive solar design and thermal insulation materials. His tenure at UT Austin was characterized by prolific publication, with over 40 peer-reviewed journal articles, 10 book chapters, and several conference proceedings. He also mentored numerous graduate students who later became influential researchers in the field of sustainable construction.
Industry Collaboration
In 1990, Krummel transitioned to industry, joining the architectural firm GreenTech Solutions as a senior design engineer. GreenTech Solutions was a pioneer in environmentally responsive architecture, and Krummel's expertise was instrumental in developing the firm’s first award-winning project: a LEED Platinum–certified high-rise office building in Austin. He led a multidisciplinary team that integrated advanced glazing systems, double-skin facades, and natural ventilation strategies, resulting in a 30% reduction in energy consumption compared to conventional designs.
Career in Public Service
National Institute for Green Architecture
In 1996, the U.S. Department of Energy established the National Institute for Green Architecture (NIGA) to spearhead research into sustainable building practices. Krummel was appointed as the institute’s founding director, a position he held until 2009. Under his leadership, NIGA produced a comprehensive set of design guidelines, known as the Green Architecture Code, which became a foundational reference for architects and engineers nationwide. The code emphasized modular construction, renewable energy integration, and water conservation techniques.
Policy Advocacy
Krummel was actively involved in shaping federal policy related to building codes and energy efficiency. He served on the Federal Energy Regulatory Commission’s (FERC) Advisory Committee on Building Energy Standards, where he advocated for the inclusion of green building metrics in national performance benchmarks. His testimony before Congress on the importance of energy-efficient construction was cited in the passage of the Energy Independence and Security Act of 2007, which mandated higher energy performance standards for federal buildings.
International Outreach
Recognizing the global nature of environmental challenges, Krummel represented the United States at several United Nations conferences on climate change and sustainable development. He chaired the international task force that developed the “International Sustainable Building Initiative,” a collaborative platform that facilitated knowledge exchange between architects, engineers, and policymakers across 45 countries.
Academic Contributions
Research in Renewable Energy Integration
Krummel’s research portfolio includes pioneering studies on the structural integration of photovoltaic arrays, wind turbine microgenerators in building envelopes, and smart grid interconnectivity. His 1992 article in the Journal of Solar Energy, “Distributed Energy Generation in Multi-Storey Buildings,” presented a novel model for predicting energy output and load balancing. This work laid the groundwork for subsequent developments in microgrid technology.
Advancements in Building Materials
Another area of Krummel’s expertise lies in advanced construction materials. He co-authored a 2001 study that evaluated the fire resistance of recycled aggregate concrete, leading to the development of a new class of eco-friendly building blocks. The study, published in Construction and Building Materials, showed that recycled aggregates could maintain structural integrity while reducing embodied carbon by 25%.
Educational Publications
Krummel authored the textbook “Sustainable Structural Design” (Springer, 2005), which has become a staple in civil engineering curricula worldwide. The book systematically integrates environmental considerations into the design process, covering topics from life-cycle assessment to adaptive reuse strategies. It received the Distinguished Teaching Award from the American Society of Civil Engineers in 2006.
