2022 - RESEARCH
The Catherine Commons Deconstruction Project describes the penalized deconstruction of a 1910 residential building in Ithaca, NY. The project is unique as it allows a side-by-side comparison of demolition and deconstruction processes on almost identical buildings within the same economic setting. The case study includes comprehensive research on deconstruction’s local potential, documenting the quantity and quality of materials saved to the resale market, the time and labor required, and the total cost – including environmental and social costs that are typically not factored into construction and demolition budgets.

MycoBuilt represents a cross-disciplinary research collaboration leveraging the expertise of biologists, engineers, architects and economists from Cornell University and external industry partners to develop both new technologies and a new architectural language combining the specific qualities and potential of urban (construction) and rural (agricultural) waste streams with the incredible potential of fungal mycelium.

Sustainable design and construction require holistic thinking across a wide variety of topics and fields: Socio-cultural, economic, ecological, functional and aesthetic, local as well as global factors must be considered and understood as equivalent and interacting with one another. This complexity makes it impossible to convey simplified recipes and answers, or suggest generally valid applications. Sustainable design and construction are rather the result of an unbiased, critical perspective and, consequently, a personal attitude towards the task - based on empirical values from one’s own experimental activities and a comparatively broad foundational knowledge base on topics of sustainability.

RhinoCircular, a CAD plugin for Rhinoceros3D and Grasshopper developed within the Circular Construction Lab, is a software tool to evaluate material circularity in the early phases of architectural design. It assesses a building design’s environmental impact with respect to its embodied carbon values and circularity: the degree to which design solutions minimize extraction and waste in favor of reusable, recyclable, and renewable material resources.
2021 - NETWORK
The Circular Construction Lab is a founding partner of CR0WD: Circularity, Reuse and Zero Waste Development, which is comprised of Historic Ithaca/Significant Elements, the Susan Christopherson Community Planning Center, the Circular Construction Lab and the Just Places Lab of Cornell University, Finger Lakes Reuse and Cortland Reuse, and the Preservation Association of Central New York.
2021 - RESEARCH
The CI:RCLE project team aims to investigate circular potentials of the local built environment by capitalizing on material reuse and recycling; new construction methods; the reactivation of embodied carbon, water, and knowledge; green job creation; and new business models of production and construction. CI:RCLE represents a wide and diverse community of academic and industrial partners promoting and enabling circular construction through integrated research, case study projects, and policy recommendations in support of the City and Town of Ithaca’s Green New Deal and 2030 carbon-neutrality goals.
2021 - Exhibition
The 17th International Architecture Exhibition - Venice Biennale - took place from 22 May to 21 November 2021 in the Arsenale and the Giardini in Venice, Italy. Curator Hashim Sarkis called on architects to imagine spaces in which we can generously live together in different ways, in the context of widening political divides and growing economic inequalities. As part of an intercontinental team spanning ETH Zürich, KIT Karlsruhe, EiABC Addis Ababa and Cornell University, Felix Heisel and Marta H. Wisniewska co-developed a contribution titled “Quo Addis? Conflicts of Coexistence”. The resulting urban model of Addis Ababa depicts the historical and architectural development of the Ethiopian capital from the age of Menelik’s empire in the 19th century until today in an abstract and at the same time precise and clear way.
2019 - Built Work
The Mehr.WERT.Pavillon by 2hs architects and engineers and KIT Karlsruhe addresses the question how we can perform a paradigm shift in the way we use our resources, from the currently dominant linear economy towards a circular economy of closed and pure material cycles. On the one hand, the pavilion makes use of the existing urban mine – all materials used in the project have already undergone at least one life cycle, either in the same or in a different form. On the other hand, it acts as a material depot, which will become available again for future constructions at the end of the exhibition.
2018 - Built Work
The Urban Mining and Recycling (UMAR) Unit is located within the NEST research building of Swiss Federal Laboratories for Material Science and Technology (Empa) in Dübendorf, Switzerland. The building design created by Werner Sobek with Dirk E. Hebel and Felix Heisel proves that circular construction is possible already today.
