FAQ for CBECC-Res 2013

4. Is the file needed for uploading a project to HERS generated any time I run an input file? If not, what
do I need to do so that I do not have to re-run a job to get this file?
No, the file is not always generated. Once you are ready to move forward with a job (send a draft of
the CF1R to the client, for example), you should check the two boxes shown below for the PDF and
Full (XML) under the Analysis tab. This will produce a CF1R with the “not registered” watermark and
create the file “[filename] - AnalysisResults-BEES.xml” that will be needed to register the program.
You will find the file in the projects folder.
5. Can I model more than one garage in a single input file?
No, you can only have one garage zone. Combine the garage areas and surfaces into one garage
zone to account for one or more garages.
6. If I’m getting an error with no message, how can I try to figure out the cause?
You can find clues within the file “rules.txt” file found in the Data/Documents/RulesetSource/Rules
folder of your CBECC-Res installation. You can find out about all of the error trapping done in the
rules by searching for the "PostError" function in the rules.txt file.
Frequently garage surfaces cause errors. There should be six surfaces defined for each zone in order
for the airflow network model to accurately model the zone.
FAQS POSTED ON OCTOBER 23, 2013
1. Can I add materials to CBECC-Res?
No.
2. There are no U-factors for the opaque assemblies on the CF1R. Why not?
We no longer use U-factors for opaque assemblies. The software uses a much more detailed
calculation for the thermal performance of opaque surfaces, so the relevant information for the
builder and inspector is the insulation and materials used to make up the assembly.
3. In multi-family, how do I determine the correct number of water heaters to show in my water
heating system?
It is the number of water heaters serving the zone to which you’re assigning the system. So if there
are 4 dwelling units in the first floor zone, each with its own water heater, the system defined
should have 4 water heaters.
4. Is 1-coat stucco shown as R-4 sheathing insulation and 3 coat stucco exterior finish?
No, the exterior finish is set to R4 synthetic stucco to show the combination of insulation and the
“paint.” The 3 coat stucco finish is not the appropriate finish for 1-coat stucco.
5. Water heater efficiencies have changed. What is the correct way to enter the various efficiencies?
