ok so "flat with HVAC gear" is that you consider "not passive"? Better question for you: why aren't datacenter roofs covered in solar, especially in places like

  What open source tools could we use to model the impact on thermal exchange efficiency of: roof surface area given prevailing wind, the impact of rooftop renewables on laminar flow, features that cause passive airflow though the building,? FWIU wind turbines and solar panels have a local heating effect at ground level; but does that help exchange wasted heat with the air above the datacenter? (The heat is wasted inefficiently instead of thermoelectric recapture) Really white paint reflects thermal radiation, but is probably very bright for techs maintaining units on the moon. Some PV (and maybe TPV? [Agrivoltaic]) panels have an underside with an additional layer of inverted panels.
