Ecotect-1020:WARNING:Material-1(No Material)high surface reflectance trunc 0.85

[Anonymous]

Hi,

I keep getting this error message from ecotect when I do an electrical and daylight analysis on my model :

"Re: 1020: WARNING: Material -1 (<<No Material>>) high surface reflectance truncate to 0.85".

I've checked the reflectances of all the internal and external surfaces and they are in the 0.5 to 0.65 range (so they're not too bright). The internal daylight analysis grid shows me values of 800-1000 lux, even though I've set the time to 10pm in December, in Greece! 

I have recently inreased the height of the space from 3.5m to 4m and I've added some lights in (fluoroscent tube lights)...could this have anything to do with this? But this doesn't make sense as the high lux values on the grid are for DAYLIGHT values and the ELECTRICAL light illuminance values are around 60 - 100 lux! 

If anyone could help I would appreciate it!

Thanks.
