You may not be a window expert but you are way ahead of the game already.
While I think some of the passive solar stuff that Serious does has some application value and certainly in your case, it comes at a cost prohibitive price tag in my opinion. I think you are better suited to go with either a clear glass window in a triple pane krypton format on the South facing side and put triple pane krypton (with Low-e) on the North and East sides. Depending on your West facing windows and their exposure, they might be passive solar candidates as well.
You need to look for a window with as low an air infiltration number as you can get in my opinion.
Are you current windows wood? Are you doing full tear outs or inserts?
You can get a very good triple pane window with phenomenal numbers for reasonable numbers if you shop it. I would also look into some air sealing work and insulation to compliment the windows.
Thanks for the input, full replacements. I currently have wood casements and there is some rot going on outside. Inside, I have no evidence of water intrusion and the house supposedly had blown in cellulose done prior to us buying it 1.5 years ago. My goal for a contractor is someone who can recognize a problem once everything is torn out, inform me of that problem and repair it properly. It would be foolish to cover up a problem with new windows and not do anything to solve it.
My west side is double sliding glass doors that are pretty new (Andersen), so I don't have too much to worry about there. I was given a number of $750 per, installed on the 501. I know my man has wiggle room because he's quoting me the same price for the monster size 5ft long windows as he is for the tiny bathroom windows. What triple pane windows with low infiltration would you reccomend I shop that you think I can work the salesman on. Also, wondering if it is not a good idea to have a contractor not associated with the sale put in windows or if I should strive to do it all in one place.
Thanks again for all the help.
