Frau M. Sc. Isil Kalpkirmaz-Rizaoglu



Isil Kalpkirmaz-Rizaoglu is an architect and an urban planner working in the field of sustainable building design and environmental modeling. She holds bachelor degrees on architecture (in 2010) and urban planning (in 2013) from the Faculty of Architecture at Istanbul Technical University, Turkey. After graduation, she has worked as a design and a site architect in both in design offices and construction sites for large scale projects ranging from housing to hotel uses between 2013 and 2018. She got her Master’s degree from Environmental Control and Construction Technology graduate program in 2018.

She is currently a PhD candidate under the supervision of Prof. Dr. -Ing. Karsten Voss at the Building Physics Chair of the University of Wuppertal, Germany, where she is also working as a research assistant - taking part in research projects and teaching architecture master courses - since 2019. Her PhD research, namely Performance Based Early Design (PBED), focuses on performance evaluations in architectural early design phase – particularly in architecture education, for the development of new teaching methods, as well as design & simulation workflows, which are simplified enough to be adopted in early design investigations. Parametric design and simulation, and optimization methods are part of her research. This research was partially supported by German Academic Exchange Service (DAAD) through teaching assistant fund within the STIBET doctoral program in 2021.

She was a member of the research college EnEff.Gebäude.2050 supported by the German Federal Ministry for Economic Affairs and Energy (BMWi), between 2019 and 2020. She has been working in Solar Decathlon Europe 21/22 as a building simulation professional. She completed the international qualification programme SelmaMeyerMentoring for the female researches in 2022.


Title and abstract of thesis project

Informing, Stimulating and Inspiring Architectural Design


Changing needs and expectations in architecture practice, not only regarding environmental issues, but also the technological advancements, fulfilling comfort needs and managing energy efficiency, as well as advancing aesthetic quality of a design are more challenging for architects than ever. In parallel to these developments, the role of digital tools of design and building performance analysis are redefined and the use of them in an integrated manner by architects became a must rather than option. Including Building Performance Simulation (BPS) in design process as early as possible and using it not only as performance evaluator, but also as a design stimulator to inspire the architects during design exploration is one of the most possible paths to sustainable environment.

Utilizing design and BPS tools in tandem can be an important pillar for supporting efficiency, variety and flexibility of the design process. Most architects meet BPS during their education, and the experiences gained throughout play a significant role in terms of adoption of BPS tools in their future works. However, BPS is often an additive in design education rather than an inherent part, therefore new methods are needed to provide design-integrated use experiences. In response, this research aims to present a novel approach for Performance-Based Early Design (PBED) for architecture students. Methods; such as literature review, surveys & interviews, examination of existing design and BPS tools, development and test of Performance-Based Early Design (PBED) prototypes, structuring and guiding an architectural design studio, and case studies are applied during the research.
