I have been long thinking if I were to choose only one tool that would give me the adequate flexibility to do conceptual design stage analyses what that would be?
Please name your favorite tools/GUIs and the pros and cons.
I am particularly interested in options that allow FAST and RELIABLE access to weather analysis, massing, shape, orientation, daylighting, and natural ventilation studies with easy transition/integration with more detailed HVAC and passive systems analysis.
