Simulating Availability of Radiative Cooling


The SimRoof program I have been developing can now create graphs of the availability of radiative cooling. This "Perfect CoolRoof" graph shows that in Guam:
  • The roof will provide more than 7 W/m2 of cooling 99% of the time;
  • the roof will provide more than 22 W/m2 of cooling 90% of the time;
  • the roof will provide more than 60 W/m2 of cooling 50% of the time (the median);
  • the roof will provide more than 80 W/m2 of cooling only 10% of the time;
  • the roof will provide more than 90 W/m2 of cooling only 1% of the time.
