Preservationists often say, “the greenest building is the one already built,” but what does that really mean for carbon reduction? This session explores how historic buildings—rich in embodied carbon and reuse potential—are essential tools in fighting climate change. Learn how Historic New England is charting a path to carbon neutrality by 2050, with Casey Farm as a case study in audits, planning, and action. Plus, discover how The Georgia Trust’s Green Program leverages performance data—like blower door tests and solar assessments—to help older buildings outperform new ones and challenge industry myths with facts.

Speakers:

• Ethiel Garlington, Executive Director, The 1772 Foundation
• Joie Grandbois, Director of Sustainability, Historic New England
• Mark McDonald, Organization & Preservation Consultant

Learning objectives:

1. Preservation is climate action—Preservationists know that the "greenest building is the existing one," but may not be able to articulate why existing buildings are so important to reducing carbon. From embodied carbon to recycling building materials—historic buildings must play a central role in the fight to save the planet.
2. Planning—Hear directly from Historic New England staff as they lay out their ambitious goal to reach carbon neutrality across their real estate portfolio by 2050. Diving into Casey Farm as an example, attendees will learn how surveys, planning, energy audits, and assessments are critical to developing effective climate action plans.
3. Data collection—In order for historic buildings to perform efficiently and outperform new construction it's imperative that data is collected on the building's performance. From blower door tests to solar assessments, data collection informs owners on best practices, return on investment rankings, and dispels myths promulgated by manufacturers.
