Juliana Felkner

Assistant Professor

Juliana M. Felkner was born in Kansas City, Missouri, USA. She studied architecture and spatial planning at the University of Kansas and the Royal Institute of Technology (KTH), Stockholm. She worked for Ateliers Jean Nouvel in Paris before moving to Zurich to conduct her Ph.D. research at ETH in the Chair of Structural Design and the Chair of Structural Mechanics. She is a member of the Swiss Society of Engineers and Architects (SIA). She started as a tenure-track assistant professor at the School of Architecture in 2016 and is an advisor in the Center for Sustainable Development.

Prof. Felkner’s research and teaching addresses the societal challenges that come with increasing urbanization of the world. Smart urban growth requires holistic strategies ranging from historic preservation and spatial development to architecture as materialization of the planning process and energy-related questions pertaining to a sustainable built environment.

For example, inner densification as a means of transforming an area towards more efficient use of land means that in both Europe and North America, mid-rise and tall buildings will become an increasingly important building typology with which to contend. Furthermore, the transformation of historic and industrial sites into residential areas has to be harmonized with the aims of historic preservation.

Finally, a holistic approach demands that buildings be designed or retrofitted such that they operate with low carbon emissions and integrate into the urban fabric.

Prof. Felkner received the Faculty Innovation Grant for 2017 for the project, "Form and Energy: Bridging Engineering and Architectural Education through a collaborative project utilizing interactive architectural models, sensors, control systems and real-time data"

She is currently working with the School of Engineering on a project, "Integrated Transformation of Urban, Building, and Energy Systems," which simulates programmatic spatial development scenarios resulting from integrated modeling of the energy system and the built environment.
