Ilka Cassidy, CPHC, co-founder of Holzraum System, is passionate about Passive House envelope design and building science, focusing on the benefits of natural building materials. She grew up in Germany and received her Diploma of Engineering/Architecture degree from the RWTH Aachen. Ilka connected to the U.S. during her year at the University of Washington in Seattle, where she won a scholarship to study with the graduate program. Eventually, she moved to Philadelphia and co-founded C2 Architecture in 2005. She has worked on multiple projects as a Certified Passive House Consultant and is an active member of Philadelphia’s Green Building United.
Proposed Session Description
A group of women architects from different backgrounds will take a critical look at individual certification standards to advocate for a more holistic and collaborative way of thinking. While certifications are crucial to pushing the limits of sustainable construction, validating investments, and providing quality assurance, they sometimes risk a narrowed viewpoint, shifting priorities towards meeting a prescribed matrix and away from big picture values better benefitting building occupants and the environment. This presentation showcases individual projects and lessons learned from pursuing single and multiple certifications, and how they can be leveraged to create truly regenerative buildings. Guided by a combination of certification goals (LEED Platinum, Living Building Challenge, Passive House and WELL) on various building scales and construction methods--including prefabrication--the women and their projects strive towards the ultimate goal of zero/positive carbon, health, and wellbeing. In conclusion, the group will analyze further which certifications lend themselves to a successful overlay and when a multiple certification strategy is difficult to justify.
Why is this session important?
With the proliferation of so many new standards, it is important to find opportunities for synergies between them so that they can enhance one another. This session offers a unique perspective on using several certification standards to achieve the best outcome, potentially even risking certification all together. Aligning priorities of health and environment with realistic project based goals is at the center of this thought provoking discussion.
Diversity and Inclusiveness
By choosing 100% women speakers - coming from three different continents, we would like to raise awareness of the typical underrepresentation of women on project teams and showcase a collaborative work environment that encourages the willingness to share value.
Learning Objectives
Learn about the various certification standards and describe how the combination of multiple building standards can enhance the design process and outcome.
Recognize ways to reduce operational carbon and embodied carbon through design analysis.
Present lessons learned as a means of considering future project possibilities, including how we as practitioners can ensure our projects address the needs of health and well-being and just communities.
Encourage a holistic approach which fosters communication, collaboration and value sharing within and beyond project teams.

Kelly Moynihan will present the Keller Center, a Living Building Petal Certification and LEED Platinum project, a 2020 AIA COTE Top Ten recipient. Ilka Cassidy will present a case study with eye opening results regarding Embodied Carbon on a large single-family home, using Passive House and Prefab strategies in combination with wood based building products. Christina Aßmann will describe how the design of Nuthatch Hollow aims at overlaying Living Building Challenge and Passive House. She will also explain how she incorporates her research into her work as an educator. Sangeetha Sambandam will share her work as project architect on a Federally funded LIHTC Passive House - Multiphase, Multifamily Affordable Housing project - Village at Park River, CT. Kristie Broussard will discuss how the WELL Building Standard aligns with the LEED, LBC, and Passive House certification systems and outline what makes WELL unique among them.
