[Greenbuilding] night insulation for windows savings

[Bob Irving]

The RETScreen series of spreadsheets <www.retscreen.net> use binning  
to process their weather files.
They are also a free source of software for some purposes, green  
building-wise..

Taking comfort instead of savings depends on how warm your house is  
in the first place.
Brenda Boardman at the Environmental Change Institute in Oxford found  
that poor people with cold houses prefer warmth to savings when she  
first started studying "fuel poverty"

Lawrence Lile wrote,"The technique that you are looking for is called
"bin
data".  In the 1980's this was a commonly used technique, but it is
falling
out of favor as more powerful computer programs get cheaper. "

  Do you recommend a software program for modeling energy conservation
and
production options for the performance of buildings?

I did find a source of bin data from ASHRAE.  However it was going to
cost
me money.  Therefore, I would like to survey my other options.
