In this new episode of All Things Facades Podcast, we dive into what it actually takes to decarbonize buildings at scale, starting with the building envelope.

Featuring Andrew Zech, CEO of Alpen, the conversation traces his path from financing billions of dollars in commercial energy retrofits to leading a high-performance glazing manufacturer.

We unpack why retrofits—not just new construction—are critical to reducing emissions, how secondary glazing and thin-glass IGUs can deliver real payback and comfort gains, and why tenant experience often drives decisions more than regulations alone.

We also discuss how manufacturing automation, third-party validation, and a flexible “toolkit” approach are helping bring high-performance glazing into the commercial mainstream.

This episode is for anyone focused on envelope performance, retrofit strategy, and making decarbonization work in the real world.
