On today’s podcast, Sean Heath had a chat with Michael Adlerstein, former Adjunct Professor, Columbia University Graduate School of Architecture and recently retired Assistant Secretary General for the Renovation of the United Nations.

They discussed the awe that accompanies that type of project, the critical need to preserve a building’s original intent when restoring it, balancing the energy needs with the structural integrity, and what it feels like to be responsible for such historic places. (Sean might have gotten a little speechless. Seriously.)
