Black exterior walls confusion
We are building a passive solar house. .
We are close to Dallas Texas
we have approx 2644 Heating Degree days and 2811 Cooling Degree days.
here is the problem. In BEopt 2.8 I compared a very black exterior to a very white one, everything else being the same and its showing that the black cladding actually uses less energy over a full year than the white cladding.
could this be possible for DFW tx?
cooling setpoint was 74 and heating was 71
am I doing something wrong or should I get the black wall since both my spouse and I prefer the esthetics of black over white
