Hello,
I am new to eQUEST and now is modeling a office building. Afer I ran the simulation for the building peformance analysis. I got the error messages for each thermal zone in the detailed output files.
**WARNING**********************************************************************
Zone: EL1 West Perim Zn (G.W1) could not successfully
allocate all equipment energy to the 5-minute bins
because of an equipment overload. The peak load
used in ECONOMICS will not include the fraction due
to the overload, but the PLANT reports will.
Mon/Day/Hour: 1 2 8 Energy: 22.9 Unallocated: 2.921
In my model, actually I didn't define the equipment load. Only internal load is the lighting load. Does anyone have any ideas how to fix the problem?
Thanks a lot

Hi Steve,
I checked the DOE2 dictionary and found the calcuated U-Value of the exterior wall doesn't include the outside air film in the mode of detailed date edit. Based the U-Value of the exterial wall I got from the detailed output file, the U-Value of the outside air film is 0.4 But/h.ft2.F. I guess I should include it in the as part of the wall assembly in order to meet the requirements of ASHRAE 90.1. However, in appredix A the U-Value of the outside air film is 0.17. Does eQUEST use different U-Value for the outside air film?
For Wall Below Grade, the C-factor is 1.14 for the baseline model. I chose 8" HW concrete (cc05) from DOE2 library because there is no 8" mediate weight concrete with the density of 115 lbs/ft3 that has C-factor of 1.14 excluding the outside and inside air films or soil.
I really appreciate if you could give some feedback about the model setup.
Thanks a lot
