[Bldg-sim] Design Builder : Low E coated surface

[Jeff Haberl]

The "surface" depends on the climate.

Cooling dominated climates benefit from the low-E on the inside surface of the outside pane.

Heating dominated climates benefit from the low-E on the outside surface of the inside pane.

Such characteristics are normally defined by the applicable codes for a given location.

Subject: [Bldg-sim] Design Builder : Low E coated surface

Hello all,

I am trying to model several types of Low E glazing in Design Builder to understand the effect on the peak heating and cooling load.

While choosing different glazing, I could not understand which surface of the glazing has the Low E coating.

I would appreciate any inputs about this aspect.


Thanks,
