[Equest-users] HVAC sizing - triple vs. dual

[Chris Jones]

The effect of SHGC on heating energy use is very significant in cold, 
sunnier climates like Edmonton.  Whether triple pane results in 
better overall energy consumption compared with double pane depends 
on the U-value improvement and the change in SHGC.  I have witnessed 
the skepticism in many Architects reactions when you tell them that 
their super glazing system - designed for cooling climates, ends up 
using more energy than a less expensive glazing.
