Passive House Envelope Design

2 weeks ago -A double envelope house is a passive solar house design whichcollects solar energy in a solarium and passively allows the warm air to circulate around the house between two sets of walls, a double building envelope. This design is from 1975 by Lee Porter Butler in the United States.

This particular example perfectly highlights why Passive House Envelope Design is so captivating.

Establishing this unbroken air barrier is central to Passive House performance and durability. In design, we do the “red pencil test” to check that an air barrier line can be drawn around each cross-section of the building without the pencil ever leaving the paper. In the field, this air barrier is built through a combination of sheet membranes, fluid-applied membranes, tapes, and sealants that transition without interruption between components of the building envelope...

Furthermore, visual representations like the one above help us fully grasp the concept of Passive House Envelope Design.

February 27, 2017 -Designing to Passive Like any construction project, Gibson says that it’s important to incorporate the passive features into the design at the beginning. “There needs to be a continuous barrier in the envelope such that on a section drawing I can connect the outer shell elements— foundtaion, wall and roof—without lifting my pencil,” he explained.
