Dave House North pulls ahead

The Dave House North is still charging over the course of this graph, as it starts almost even with the Dave House South and ends up almost 3 oF warmer. Even though the sol-air temperature decreased as the week went on, the ambient temperature still rose and so the temperatures in the buildings also rose slightly. This may be due to the fact that the ambient temperature stayed above 40 oF on the night of the 13th. So far, it looks as if the 4 selective surface absorbers are still charging the Dave House North and could easily boost it above the Andy Shack’s day time temperature. And the improved building envelope and extra thermal mass will keep the Dave House North significantly warmer during the night.
