A sustainable future for America requires sustainable buildings. And sustainable buildings must be durable buildings. And while the mention of the word “sustainability” is usually a trigger for designers and builders to think about energy efficiency and green building materials, building durability cannot be overlooked as a critical pillar of sustainability. Simply put, a home with a fantastic thermal envelope and high efficiency mechanical systems which is also riddled with prematurely failing building materials and systems is NOT green or sustainable. Green and sustainable homes must be durable homes.
