The Valuation Metric

Hosted by Sara Gutterman, CEO, Green Builder Media
[SARA MAY CHANGE THIS BUT I WILL RETYPE IN] In a world driven by price tags, clickbait, and short-term wins, The Valuation Metric asks a different question: what do we actually value?
Hosted by Sara Gutterman, CEO of Green Builder Media, this podcast challenges the metrics that shape our decisions—from price per square foot to GDP—and explores what real value looks like in housing, business, culture, and life.
Through conversations with leaders in sustainability, technology, finance, design, and philosophy, each episode reframes success around the things that endure: wellbeing, resilience, equity, connection, and purpose.
The future belongs to those willing to measure what truly matters.
The Impact Series

Hosted by Mike Collignon, Executive Director, Green Builder Coalition
This long-form interview podcast hosted by Mike Collignon explores how sustainability moves from theory to action. Each episode features candid, in-depth conversations with policymakers, scientists, industry leaders, advocates, and innovators who are shaping the systems that govern how we build, regulate, insure, and sustain our communities. From building codes and water policy to climate resilience, housing equity, energy transition, and global risk, The Impact Series goes beyond headlines to examine the forces driving real-world outcomes.
With decades of experience in advocacy, codes development, and cross-sector collaboration, Collignon brings both institutional knowledge and sharp curiosity to every conversation—asking the questions that connect policy decisions to on-the-ground consequences.

Letters from Mariposa
Hosted by Ron Jones
Letters From Mariposa is a contemplative audio podcast hosted by Ron Jones, Co-Founder and President of Green Builder Media, recorded in spirit—and often in place—at Mariposa Meadows, a high-altitude off-grid sustainability project nestled in Colorado’s San Juan Mountains.
Born from years of designing, building, and stewarding a living laboratory of high-performance structures, renewable energy systems, wildfire resilience strategies, and ecosystem protection, Letters From Mariposa is not a technical podcast in the traditional sense.
Instead, it is a series of reflections—life stories, metaphors, recollections, and conversations—offered quietly and intentionally. These Letters explore the intersections of sustainability, responsibility, anger, joy, patience, and purpose in a world increasingly defined by speed, noise, and distraction.
Sometimes the Letters are solitary. Sometimes they are shared. But always, they are written with humility—and with the hope of offering a moment of clarity, a pause for thought, or a fleeting glimpse of wisdom.
As Ron says: “I have saved your seat at the campfire.”
