Glass Spandrels and Shadow Boxes
Glass spandrels are a common design strategy utilized to opacify floor levels in building facades. These opaque glass assemblies are integrated into… -
Sustainable Retrofit Strategies for an Existing Laboratory Building
This paper analyzes sustainable retrofit strategies for an existing research laboratory building, located in a cold climate. This facility is… -
U-Factor Matters in Hot Climates
It is commonly thought that fenestration U-factor is not a key determinant in the performance of facades in hot climates, and generally the focus of
