[EnergyPlus_Support] Lighting heat gain

["valerie3407tony" <tony@xxxxxxxxxxxx>]

Hello anyone,

I have been trying to summate the internal total heat gain for a zone.
I am using the report "Zone Total Internal Total Heat Gain", this 
gives a total, which consists, in my case of People, Electric 
equipment and Lights.

The problem I have is that the Total heat gain does not equate to the 
individual component totals.  The difference seems to be the "Total 
Internal Visible Heat Gain" for lighting, which does not appear to be 
added to the "Zone Total Internal Total Heat Gain".

As an example hourly (W) values:

Zone Total Internal Radiant Heat Gain       334.5
Zone Total Internal Convective Heat Gain    903.7
People Sensible                             161.4
Zone Total Internal Latent Gain             458.5
Zone Total Internal Visible Heat Gain        49.8
Total should be...                         1746.5

Zone Total Internal Total Heat Gain        1696.7
This is exactly 49.8 lower than the total should be.

Any comments would be welcome.
