Vikram,

The conversion from W/sq.m.-K to Btu/hr-sq.ft.-F is 5.68. This gives a
U-value of 0.162 Btu/hr-sq.ft.-F.

 

I would like to see a study of the energy consumption of this window
compared to a building with normal low-e IGU and actual radiators. 

 

Sam

I'm a little curious - is 0.92 W/m2k a good U-value? Just poking around
on online converters - it looks like the IP version of that is around
0.56 or something in that region - doesn't seem spectacular (you get
0.25 with a lot of double pane low-e IGUs). Unless the 0.922 is for the
entire glazing assembly - in which case its around the same as other
glass types. 

 

I might have got the conversion factor wrong.

Namrata,

 

I would model the heating as electric baseboards and select a glazing
type based on the U-value and SHGC.

 

Regards,

Bill

How does one model active heating windows like the ones listed below.
