A new way to retrofit old buildings ... from the outside

In this episode, I geek out with David Goldstein, founder of
Hydronic Shell Technologies, about a novel building retrofit
technology that wraps old multifamily structures in insulated
panels with built-in HVAC systems. Goldstein's approach allows
for energy-efficient upgrades without interior disruption,
potentially solving a major challenge in building
decarbonization. We dive into how the system combines exterior
insulation, air sealing, and centralized heat pumps with
individual window units to dramatically reduce energy demand and
emissions.
