Later, I replace all my windows with Loewen double and triple glazed, low-e windows (which are fantastic) and the shades still make a difference. Not as much, but certainly noticeable.

Will they pay for themselves in saved energy costs? probably not, but then, neither will the windows. Nor will many of the ecologically friendly choices I make for my home. But together, I’ve been able to reduce my oil consumption to about 1/3 the previous level.

The economic payoff argument that I see so often when it comes to “green” upgrades is largely bogus. Yes, one should know what the economics are and should prioritize projects. However, there are many aesthetic choices one makes where there is zero economic payoff. Why do these items get a free ride? How do you put a price on comfort and health of your structure?

Granted, I understand you have a pricing goal for your home, so you have to prioritize based on the economic formula, but I don’t want others to constrain themselves to this line of thought. Most people will put in shades anyway, often very expensive ones that provide minimal insulation. Why not put in less expensive window treatments that actually make the house better?
