Unfortunately, this is mostly anecdotal as I wasn't tracking temperatures inside and outside the house as I do now. So, take this for whatever it's worth.

In the summer of 2003 we had a heatwave with high temperatures in the mid to upper '90's (record high of 99°F). Daily Averages for Santa Fe, NM (87505) - weather.com When I got home from work the house would be quite hot and I would open windows and use fans to vent the hot air (no AC or swamp cooler). The house would slowly cool as the outside temperature dropped. Often, I couldn't fall asleep until after midnight and slept with either no covers or at most one sheet on the bed due to the heat.

Flash forward to the heatwave of 2010 Monthly Weather Forecast for Santa Fe, NM (87505) - weather.com. We have a new "galvalum" propanel "cool" roof, cleared eave vents, a full ridge vent, and R-50 of cellulose insulation in the attic. We still use fans to vent hot air from the house (still no AC or swamp cooler), but now I work from home and watch the temps more closely. We've had days that have been just as hot, but the house doesn't heat up as much and it cools down more quickly. I also haven't had any sweaty and sleepless nights from the heat.

According to our indoor/outdoor thermometer the max. outdoor temp. has been 102°F and max. indoor temp. has been 85°F. While 85°F is warm the house cools down pretty quickly with fans as sun sets and the outdoor temp drops.

While I wish I had better data I am much more comfortable and I don't like the heat any more than I ever have.

FWIW,
Tim
