SYSTEM AND METHOD FOR PANELIZED, SUPERINSULATED BUILDING ENVELOPES

摘要

Panelized wall and roof structures for constructing energy efficient buildings. The panelized structures have a structural layer with insulation, an airtight layer providing a primary air barrier and a vapor retarder exterior to the structural layer, a vapor open blanket layer including insulation and attached to the structural layer via structural screws, a weather resistant barrier provided exterior to the blanket layer and including an airtight, water-repelling, vapor-open fabric, and a rain screen provided exterior to the weather resistant barrier and including a drainage plane for channeling moisture away from the weather resistant barrier.

1. A system for constructing an energy efficient building, said system comprising:
at least one panelized structure having
a structural layer including a first set of voids and located at an inner area of said at least one panelized structure, said inner area being adjacent to intended living space of said energy efficient building,an airtight layer formed by a first sheathing layer providing a primary air barrier and a vapor retarder exterior to said structural layer,a blanket layer located exterior to said first sheathing layer and formed by a plurality of vertical members with a second set of voids located between each of said vertical members,a weather resistant barrier located exterior to said blanket layer and including a second sheathing layer formed by an airtight, water-repelling, vapor-open fabric,a rain screen located exterior to said weather resistant barrier, said rain screen being adjacent to outdoor space external to said energy efficient building and including a drainage plane internal thereto, said drainage plane for channeling moisture away from said weather resistant barrier; insulation for placement within said structural layer and said blanket layer; and wherein said at least one panelized structure is air-sealed and insulated within said first and second sets of voids after installation.
