In this episode of Not A 'Licensed' Architect, Stefani Thatcher sits down with David Holtzclaw, principal of Transduction Technologies and a mechanical engineer specializing in building science and high-performance homes.

With a background in aerospace and biomedical engineering, David brings a unique, science-driven perspective to residential design—challenging common assumptions about comfort, energy efficiency, and how homes actually perform.

Together, they unpack why many homes that look great don’t always feel great to live in, and how designers can bridge that gap. From window placement and insulation strategies to HVAC systems and moisture control, this conversation breaks down building science in a way that’s practical, approachable, and directly applicable to your projects.

If you want to design homes that are not only beautiful—but comfortable, efficient, and built to perform—this episode will change how you think about your plans.

What You’ll Learn

• Why comfort—not energy efficiency—should be your starting point• How the building “shell” drives 60–80% of heating and cooling performance
• The biggest mistakes that lead to mold, drafts, and uncomfortable homes
• How window placement and orientation impact both comfort and efficiency
• Why tighter homes require controlled ventilation—not “breathing”
• When systems like heat pumps and radiant heating make sense• How to balance aesthetics, budget, and performance in real-world design

Every beautiful home is built twice — first on paper, then on-site. But what happens in between those stages is where most projects fall apart.

In this episode, I’m joined by Kimberly Parker, founder of Kimberly Parker Design and creator of Four Stripes, a new app helping design teams stay aligned from concept to construction. With 15+ years of experience in luxury residential projects, Kimberly shares how strong systems, clear documentation, and professional respect between trades can make or break a build.

Her approach flips the script on traditional design. It’s not just about creativity — it’s about communication, precision, and advocacy. Because when your design packet runs 50 pages deep, you’re not just handing off drawings… you’re leading a process.
