[Greenbuilding] equatorial facing windows are net solar gains

[Doug Kalmer]

There's several things I find critics of direct gain Equatorial facing windows often overlook. One is movable insulation, I'm really glad to see that many people on this list have built and use their movable window insulation. I've been using mine for over 22 years- http://www.builditsolar.com/Projects/Conservation/ThermalShades/ReflectexShade.htm. The easier it is to use, the more it will be used. Another is the way window technology has increased, greatly improving R-value and heat retention. Yet another factor critics often overlook is the human factor-the ability to feel warmer at lower air temperatures when you're surrounded by warm thermal mass, radiating heat at you. Compare this to fan forced systems blowing a breeze at you-if that breeze isn't about 85 degrees or more, it's going to feel chilly. My home gets a solar gain even on bright overcast days.
