    Understanding climate action through the words we use

    Keep an ear out for an easter egg after the outro on this one.

    The words we use matter. Terms like "sustainability”, “net zero” and “resilience” signify our industry's evolving priorities and concerns. These “buzzwords” reflect current cultural circumstances within the AEC industry and larger society while also actively shaping how we approach and address these issues.

    In this episode will be exploring the meanings and relationships between many of the current buzzwords that are alive in the AEC today. If you’ve ever wanted to deepen your understanding of words and terms like “sustainability”, “net zero”, “embodied carbon”, “circular economy”, “resilience” or “adaptation” you’ll appreciate this interview w/ Kjell Anderson of LMN Architecture in Seattle.

    Yes, buzzwords come and go. We routinely air quote them somewhat irreverently. But do not be fooled - buzzwords are also important. Far from being superficial, these trends in language mark the emergence, acceptance, and eventual integration of new, often significant, ideas. When a word gains prominence, it often signals a collective reckoning with the issue it represents. Conversely, when it fades, it may indicate that the idea has either been absorbed into the mainstream, superseded by more urgent concerns, or—sometimes quite worryingly—been deprioritized.

    Dictionary definition of “Buzzword”: (pejorative) A word drawn from or imitative of technical jargon, and often rendered meaningless and fashionable through abuse by non-technical persons in a seeming show of familiarity with the subject.

    Kjell Anderson

    Kjell is LMN’s Director of Sustainable Design and leader of LMN’s Green Team, spearheading initiatives into energy modeling, materials + health, and water use reductions. With 24 years of experience, Kjell is well-regarded at local and national levels as a sustainability expert. He is a founding part of Seattle’s 2030 Roundtable, an inaugural member of AIA’s National Energy Leadership Group, and in other roles in setting practical and innovative directions for the profession. Kjell has contributed to the design of dozens of LEED New Construction projects, plus Pilot projects under USGBC’s Neighborhood Development and Commercial Interiors programs, including several Gold and Platinum-certified projects. He is the author of Design Energy Simulation for Architects, published by Routledge in 2014, and has guest taught Arch 533 (Advanced Environmental Systems) at the University of Washington. Kjell earned a Bachelor of Science in Architecture from Washington State University.

    Some of Kjell’s representative projects include the Hyatt Regency Seattle, Seattle Aquarium Ocean Pavilion, and the Eastside Tech Tenant East Campus Modernization and RedWest South project.

  • Telling Better Stories
    2025/02/26

    “The world is not made of atoms, the world is made of stories”

    Muriel Rukeyser

    “Where do buildings come from?” is a question that comes with a story. Less often asked, “Where do buildings go?”. The evolving story human society tells itself in answer to those questions is worth unpacking thoughtfully. That’s what happens in this episode. Join Kristof as he shares a conversation with Greg Esparza on the power of storytelling and the connection between stories and the materiality of buildings. The power of storytelling is clear in the ability to connect people, foster empathy, and transmit knowledge and shape cultural values. The materiality of buildings is itself a response to storytelling.

    Every building belies the presence of an underlying story about our relationship with nature. At every step of the design and construction process we make decisions. What are those decisions based on? Unfortunately the answer is not often evident and is likely tangled up in outdated ideas based on stories that no longer make sense. The importance of biogenic building materials as an emerging theme in the AEC is not just their materiality, it’s deeper. It is the story of us all coming to our senses - both literally and figuratively - our senses of sight (of course), sounds, smells, and textures - while also thinking about where buildings come from and where buildings go.

    Ultimately the choices we make in how we deliver homes to ourselves impacts our felt sense of life altogether. Why not curate materials for our homes that actually make us feel good? Turns out when we do this we find that these same decisions support the AEC’s ultimate triple bottom line of healthy homes, healthy people, healthy planet.

    Greg Eparza

    Greg Esparza is a designer and builder with over a decade of experience in custom residential design and construction as a co-founder of Moontower Design Build in Austin, TX. In 2021, Greg immersed himself in designing and building a prototype project called Cross Cabin, a “plant-based” home made of hemp, cork, and cross-laminated timber for himself and his family in Austin. Inspired by this experience. Greg established Cross Cabin Build & Supply to represent and distribute healthy, high-performance, and low-carbon building materials in Texas. Greg has a passion for building with natural, plant-based materials rooted in the commitment of the AIA Architecture & Design Materials Pledge to support health at three scales–human, social, ecosystem–and to prioritize climate impact and circular economy considerations with all material specifications. The Cross Cabin has been featured on the Build Show Network, Dwell+, Passive House Accelerator, The Architect’s Newspaper, as well as the 2023 AIA Austin Homes Tour where the most frequent feedback on the home was “I love the smell!”.
