Building Envelope

The building envelope protects us from the elements, enables comfort, and ultimately allows us to be at home in our houses, to be productive at the office, to learn in school, or to heal in the hospital.

A building envelope—also commonly called a "building enclosure," should:

  • support comfort

  • manage moisture

  • not poison us or the planet

  • allow us to breathe clean air

When possible, it should do all this while using resources effectively—durably, energy-efficiently, and with low embodied impacts.

Here you’ll find strategies for envelope design and material selection that help balance all these demands and more.
