Passive design analysis is a very helpful comparison tool in Weather Tool, and I have a few suggestions to make the results a bit more useful:

* Provide the option to show values on the bar chart, so that percentage and number of comfort hours can be compared between different passive strategies as well as the climate baseline. (I suppose you may have eliminated this to make the results more "representative"?)
* Color code or separate the "after" bar in the results to show the number of cooling vs heating hours that were captured from the selected strategies. This would be especially helpful for evaluating the use of thermal mass.
* Report these values at the top, or in a separate chart that can be exported from Weather Tool.

My thanks for creating such intuitive and useful visual analysis tools -- Weather Tool and Ecotect are both a pleasure to work with. I look forward to your next revisions!
