Combi-sensor systems
Certain aspects pertain to a combination sensor comprising a set of physical sensors facing different directions proximate a structure, and configured to measure solar radiation in different directions. The combination sensor also comprises a virtual facade-aligned sensor configured to determine a combi-sensor value at a facade of the structure based on solar radiation readings from the set of physical sensors.

11. An apparatus for controlling one or more components of a building, the apparatus comprising at least one controller configured to:
control, or direct control of, the one or more components of the building based, at least in part, on a plurality of radiation values determined at a plurality of positions of the building, wherein the plurality of positions include a first subset of positions and a second subset of positions, and each position of the first subset:
lacks a physical sensor, and
faces a corresponding direction toward which no physical sensor is directed;
wherein each position of the second subset is associated with a corresponding physical sensor.
12. The apparatus of claim 11 , wherein the one or more components of the building comprise: a fire system, an elevator system, a power system, a security system, a lighting system, a ventilation system, a heating system, a cooling system, or a heating ventilation and air conditioning (HVAC) system.
13. The apparatus of claim 11 , wherein:
to control, or direct control of, the one or more components of the building, the at least one controller is configured to consider a second radiation value determined at a second position of the building, wherein the second position lacks a physical sensor, and is facing towards a direction to which no physical sensor is directed.
14. The apparatus of claim 11 , wherein:
the one or more components of the building comprise a tintable window disposed in the building, and
the at least one controller is further configured to adjust, or direct adjustment of, a tint of the tintable window to adjust an amount of light passing through the tintable window.
15. The apparatus of claim 14 , wherein the tint is adjusted to a tint value determined based on at least one of the plurality of radiation values and a space type associated with a region of the building in which the tintable window is disposed.
16. A non-transitory computer-readable medium comprising computer-executable instructions, wherein the computer-executable instructions, when executed by one or more processors, cause the one or more processors to execute operations comprising:
controlling, or directing control of, one or more components of a building based, at least in part, on a plurality of radiation values determined at a plurality of positions of the building, wherein the plurality of positions include a first subset of positions and a second subset of positions, and each position of the first subset:
lacks a physical sensor, and
faces a corresponding direction toward which no physical sensor is directed;
wherein each position of the second subset is associated with a corresponding physical sensor.
17. The non-transitory computer-readable medium of claim 16 , wherein the operations further comprise determining, or directing determination of, the plurality of radiation values based, at least in part, on one or more clear sky irradiance values and data from a plurality of physical sensors.
18. The non-transitory computer-readable medium of claim 17 , wherein the operations further comprise adjusting, or directing adjustment of, at least one of the one or more clear sky irradiance values based, at least in part, on data from one or more physical sensors and/or a virtual sensor corresponding to the plurality of radiation values determined at the plurality of positions of the building.
19. The non-transitory computer-readable medium of claim 17 , wherein the plurality of radiation values are based, at least in part, on a virtual sensor that is based, at least in part, on the data from the plurality of physical sensors.
