[EnergyPlus_Support] Re: How to find out the direct solar radiation falling into an internal surface

Dear Dr Li,

do you know what I am doing wrong in this case? I am getting the following warning when I am asking to e+ to produce an output with the direct solr radiation. I have try a determinate surface and also a zone and i getting the same warning.


** Warning ** The following Report Variables were requested but not generated
   **   ~~~   ** because IDF did not contain these elements or misspelled variable name -- check .rdd file
   ************* Key=BED_1, VarName=DIRECT SOLAR, Frequency=Timestep
   ************* Key=BED_1, VarName=DIRECT SOLAR, Frequency=Timestep
   ************* Key=LIVING ROOM, VarName=DIRECT SOLAR, Frequency=Timestep
   ************* Key=LIVING ROOM, VarName=DIRECT SOLAR, Frequency=Timestep
   ************* There are 4 unused schedules in input.
   ************* Use Output:Diagnostics,DisplayUnusedSchedules; to see them.
   ************* EnergyPlus Warmup Error Summary. During Warmup: 0 Warning; 0 Severe Errors.
   ************* EnergyPlus Sizing Error Summary. During Sizing: 0 Warning; 0 Severe Errors.

Solar angle altitude and azimuth are available as an output. The reference points for daylighting object provide  the light intensity at the table or floow level.

The output produce by energyplus is telling than less than 4.78E-03 w/m2 are falling into the floor at 10.30 when i was expected more radiation.
