One way is to model the vacuum gap using an equivalent “gas” approach. The WindowMaterial:Gas object has Gas Type of “Custom” and allows user to set the gas properties. If you already have the overall performance of the glazing assembly, you can use the WindowMaterial:SimpleGlazingSystem object and not do a layer-by-layer description.
