In this episode of Harvesting Wisdom, guest host Diana Kruzman sits down with Irina Sokhodov (Ukrainian Green Building Council) and Olena Rybak (Managing Director, IC Ukraine) for a practical conversation on green reconstruction and energy-resilient rebuilding.

They break down what sustainable recovery looks like on the ground: rehabilitating schools and hospitals, repurposing existing buildings for housing, improving district heating and water systems, and meeting donor requirements for energy reduction and emissions performance.

The discussion also explores the trade-offs teams face in real projects—how to balance speed, affordability, and long-term efficiency—plus what “nearly zero energy buildings” mean, how renewable energy can support building performance, and why the biggest energy resource is often the energy we never have to use.
