Sometimes I forget...

how much thought went into certain aspects of this house. From the light covered 'cool roof' that reflects a majority of the solar gain and keeps the house cool:
The drought resistant plants and ground cover that keeps the ground cool:
and forgoing rain gutters to allow for run off to water the landscaping during the winter.

In addition to the Low E, reflective windows:

the interior has stained concrete flooring that keeps the house cool, high ceilings to allow for heat to rise and clerestory windows that open to let the heat out at night:
These design features keep the house comparatively cool during the summer. On average the house stays 25F-30F degrees cooler than the outside temp in the summer. When it was 109F+ this weekend, the house stayed 79 degrees.

7/18: Outside 105/Inside 83
7/19: Outside 109/Inside 79
7/20: Outside 112/Inside 80

Overall, the design of the house is meeting or exceeding the expected summer performance.

Let's talk about winter performance in 12/09.
