Sun Responsive Facade W/o Plug iN

Hey guys , I am trying to create a facade that responds to sunlight (without the use of any plug-ins) as the triangles open and close as well as a curve attractor displaying a repulsion effect somewhat. I have created the facade but is coming short with how I envisioned it to be due to the lack of plug ins which I am not allowed to use . I have tried, any help would be greatly appreciated . File is down below . is there possibility and how so could be done
