GLOBAL data in hourly results

12 posts / 0 new

Dear all,

Has anyone faced a problem where on selecting GLOBAL variables like DBT and
WBT in a 'Hourly Report Block' , the variables appear as '0' for all hours
in the excel file? I am facing such a problem. The weather file and the
eQuest file are okay, as in the same file simulation results are viewable in
all result outputs (summary, detailed, hourly). How can this be rectified?

Regards,

There is an older 3.65 build that did that (and had CAD file issues). The build 7158 from Nov 2013 in the download area fixes this issue.

A follow-up question: There is a 3.65 build dated Sept 2014 in the download area (build 7164). Anyone know what this build addresses?

My mistake. It was build 7163 from Mar 2014 that fixes the GLOBAL hourly
report info.

Brian,
I am using build 7158 and the issue remains.

Build 7164 throws errors when you try to do the Compliance Analysis which is why I went back to 7158.

Note that the Global Dry Bulb and Wet Bulb are reported in the .sim file correctly. You just have to extract the data. I have a C program I wrote years ago to do that. So I generate the .csv using eQuest then extract the OAT and paste into the column in the .csv file.

I have a different problem with hourly outputs that seems to be present in both 3.64 and 3.65.

I have built a large hourly spreadsheet to model the savings from the "Ice Bear", a small ice TES used with air-cooled DX equipment such as rooftop package units and split systems. In addition to the standard hourly electrical end-use values in the .sim file, I also export hourly dry bulb temp and cooling coil load. The problem I've noticed is that the hourly values in the .sim file are shifted off by a day. I'm just using a simple Monday-Friday office building for fine-tuning the spreadsheet. For example, day type 6 (Friday) will show no cooling electric or load and minimal lighting consumption. Day type 7 (Saturday) as expected shows no cooling and minimal lighting loads. Day type 1 (Sunday) shows considerable cooling electric and lighting as one would expect for a weekday but not a weekend day.

So far, I've been having to manually change the day types to make the loads align to weekdays, a tedious process. I'm curious to know if anyone else has observed anything similar with hourly results.

My best,

Mike

Hi Mike:

I think DOE-2 has always considered Day Type 1 as Monday. Just like Hour 1 is 12 Mid - 1 AM.

I have had problems with the hours not matching the schedule - being off by
1 - creates headache when I am trying to make sure that the winter peak is
before the start of peak demand period.
Have you checked whether it is a leap year problem - I have had that happen
to me before.

John,

Good to hear from you, old buddy.

Maybe it?s my early Alzheimer?s ? but I could have sworn Sunday was day type 1, Monday 2, etc., and holidays 8. I?ll double check the DOE-2 manuals.

Rohini,

I?ll check if it?s a leap year problem, but my gut feeling is that it isn?t. I?ve observed the day shift in Jan. and Feb. before the end of Feb. is reached and I?ve observed it in old models, say from 2011 or 2013.

Thanks for the suggestion.
Mike

I?m with John. Monday = day 1, Saturday = day 6, Sunday = day 7, Holiday = day 8.

Well maybe that?s confirmation that I should be put out to pasture to retire. ? I?ve been in this business since 1976 and can?t remember anything anymore.
