Oddly, the Autodesk Labs web site links the 2009 AU interview with Robert Aish:
"Imperative programming is characterized by explicit ‘flow control’ using for loops (for iteration) and if statements (for conditionals) as found in familiar scripting and programming languages such as Python.Only a few rare designers are going to be interested in this...?
On the other hand, Associative programming uses the concept of graph dependencies to establish ‘flow control.’ Changes to ‘upstream’ variables are automatically propagated to ‘downstream’ variables." REF
- Vasari has a great 'virtual wind tunnel' feature, but it does not model the effect of the turbulent boundary layer that leads to downwash causing danger / discomfort at the base of poorly designed tall buildings. Wind tunnels were validated against measured data. I live in a really windy city with lots of opportunities for comparison of reality and virtual environments, but it took a long time for the wind tunnel testing back in the 1980s to collect enough data to demonstrate credible 'virtual wind' environments.
- Ecotect is essentially an extremely powerful simulation analysis results viewer coupled to hand calculations developed decades ago. How might these DesignScript or Vasari options be linked to and then validated with modern simulation software that addresses the physics more directly? And how might these analytical tools be applied at a time in the design cycle of a building when they might make a difference?
- 100 years or so in the case of Sabine's Reverberation Time in the Acoustics module
- 30-40 years ago in the case of the Admittance method for thermal performance analysis which assumes essentially that climate trends (temperature and sun) can be described as sine wave 'excitations' responded to by a building in such a way that the interior (temperature) environment also follows a sine curve, somewhat delayed in time of the peak and reduced in terms of size of the peak by the amount of mass inside.
- 50+ years ago in the case of Daylighting the BRE Split Flux Method was developed as a simple way of calculating how much light arrived directly from the sky and how much was reflected off the external environment: reflected light in the room is less well handled so complex lighting environments such as atria are not well covered...
