Ep230: Brent Trenga: Recovering Architect Redefines Building – Circularity, Data Centers, & Legos
Brent Trenga joins me to spill on why construction is stuck in the Stone Age while we run space-age data centers. We geek out on circular economies, ethical capitalism, and why data centers should be built like Legos—easy to snap together, just as easy to snap apart—so growth and reuse don’t come with carbon regret. Tune in for laughs and lightbulb moments!
