Non-Regulated Lighting Load fatal error - Version 1e #434

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
***********Please select Version number and Issue Type below by adding
appropriate labels*************************

What steps reproduce the problem?
1. Start with small office prototype
2. Set NonReg LPD in core zone to non-zero number (e.g., 1 W/ft2)
3. Run Model.
4. I get a fatal error with proposed design (see attachment) when running it. 

What version of CBECC-NRes are you using? On what operating system?

Version 1e

Please provide any additional information below.

NonReg load should be a pass-through between proposed and standard design. This 
isn't that critical, but if it is not supported by CBECC-Com the field should 
be disabled.

The error seems to be caused if I don't set a schedule for NonReg Process Loads 
(leave as default of None).

Note that there is a related but different issue that is caused when I set the 
NonReg Lighting load to 2.0 W/ft2 and set the schedule for office lights. This 
should be a "neutral" input - same in standard and proposed designs, but when I 
set this, it generates a compliance margin, with significant fan energy 
difference. This shouldn't happen, since before changing this single input, the 
compliance margin is 0 (or very close to 0).

I have confirmed that the non-regulated lighting power is identical in the 
proposed and baseline design.  The change in compliance margin is primarily due 
to the fact that the baseline fans are being sized larger due to the increase 
in cooling load from the additional lights. 

Changing issue status to resolved. John, if you agree, please close issue.
