John J. Sbrega Health and Science Building
Walls and Roof
The envelope consists of a number of assemblies. Window to wall ratio is 22%.
Wall assemblies are a combination of stud and mass wall. The approach to stud assemblies to fill the stud cavity with mineral wool insulation and put 3 inches of mineral wool insulation outboard of the vapor barrier. The approach at mass walls is similar, except that the stud cavity, which is shallower, is filled with foam-in-place insulation.
The air-vapor barrier is continuous, with carefully designed transitions and tie-ins at openings.
