Failure on starting from my own files #2413

Closed dowbh closed 4 years ago

dowbh commented 4 years ago

I tried to do simulation on CEA for the buildings that are still under the design process. Therefore, I used ArcScene to build all the required data structures, i.e. all the data in the "input" folder in your example (reference-case-open). After I uploaded the data onto the CEA browser interface, an error popped up on my screen, shown below. I wonder is there any suggestions about how it might be resolved?

@dowbh, I did some reformatting of the traceback to make it easier to spot what is going on. Without more information, it looks like a problem with the coordinate system of your shapefiles.

How did you generate these shapefiles? Did you use the CEA project selection method? Or copy from a GIS?

dowbh commented 4 years ago

Step A. Since the buildings are not existing buildings yet, I used the "zone helper" on CEA and cropped the extract same site where the buildings will be located, and then I used the "District helper", "Street helper", and "Data Helper" to generate some of the required data.

Step B. I drew the building footprints (in dwg.), put them into ArcScene (version 10.7), and created the data for the footprint (age, occupancy, height, etc.) in the format that CEA requests. I created a new scenario and copied the data generated in Step A (because the district and street are the same), and replaced the original zone shapefile with the one I drew.

When I uploaded them onto CEA, I got the error. I am not quite sure what is "CEA project selection method" that you mentioned. I am also wondering if I am using ArcScene 10.7 instead of 10.6, would that be a problem (as the instruction requests below)?

daren-thomas commented 4 years ago

@JIMENOFONSECA do you know how to handle this error maybe?

dowbh commented 4 years ago

Hey Daren,

Thanks for your reply! I assigned the coordinate system of the zone shapefile as you suggested, and I put it at the same location where district, terrain, and street shapefiles are in ArcScene. It worked!

However, I am now getting a new error as below.

City Energy Analyst version 2.23 Running cea demand with the following parameters:

Originally, the parameter "Hs" was set to 0.82 when I got the error saying that the value was too small. After I changed it into Hs = 1.0, the error keeps saying that the value is too small. Even if I tried to run simulations for another building, the errors I got are all the same. Other than that, the building geometry is what is it; settings of internal loads are attached below. Do you have any suggestions on how to deal with this problem?

jimenofonseca commented 4 years ago

Since we do not support ArcScene anymore, it is difficult to know how this performs. Does the case study show in our CEA GUI/Dashboard? That is a good indicator that the files are in the right coordinate system.

Maybe you can zip and pass your case study to us? that could help to check what the problem may be.

@JIMENOFONSECA it looks like @dowbh is running this in the CEA GUI (see screenshot above). The error he is running into is the Exception: Temperature in RC-Model of building B001 out of bounds! error. Do you maybe have some advice on how to deal with this?

jimenofonseca commented 4 years ago

I think this has to do with the coordinate system. It may be happening that the files are in lat and lon coordinates, what would make the dimensions of the buildings extremely small.

I advise to do the next checks:

  1. use QGIS or arcgis and see if the zone and district file map correctly
  2. use QGIS or arcgis and see if th zone file (properties) has the coordinate system of UTM.

If some of the above is not working then the problem is with the input files. Again, it is too hard to know without the data. I advise to send it for us to help.

Attached please find the file we have been discussing on. inputs.zip

Btw, since you guys keep mentioning that you don't support ArcScene anymore, are you suggesting to build the required data on QGIS instead?

jimenofonseca commented 4 years ago

Alright we fixed it!.

Here is your scenario. We found a problem in your streets file and fixed it by rerunning the tool. We also found a problem form our end and fixed it in the development environment.

To be able to run your work do the next:

  1. Download the latest version of CEA and install the developer's version (tick the box of developer version).
  2. Run the solar radiation, building schedules and demand forecasting tool.

dowbh commented 4 years ago

I really appreciate your help. It works! Now I am trying to assign the program types to the building geometry, and I have some questions on that.

First, on the "occupancy" tag, as shown in the attached image, I wonder what the numbers mean? Are they the number of floors of a certain program? Or are they occupancy density?

occupancy

Second, how do those numbers reflect on the multiple programs within a geometry? For example, if a geometry has 2-story retail on the ground floor and a 1-story office above it, how should I build the data of occupancy?

Third, for now, I assumed that the numbers I am asking represent the number of floors of a certain program, which makes the building distinguished from each other. And I ran "Building Schedules" after the occupancy was made. However, on the "Schedules" tag, all the schedules among different buildings look exactly the same. It is kind of weird to me. Does that mean that the occupancy data is not effecting on the schedule? For instance, I assumed that hotels may consume more water than office, but now they consume the same amount of water.

jimenofonseca commented 4 years ago

Hi, so the numbers in the occupancy database are from 0.0 to 1.0 and represent ratios of gross floor area per type occupancy. The sum of every row should be equal to 1.0.

After changing the occupancy. You need to rerun the data helper, which will adapt the other databases accordingly.

This is to avoid that the changes you do building by building become overwritten sporadically once you chance the occupancy.

I hope this helps. Btw. The search button should be able to show what any variable means. Let us know if it does not work. On 13 Nov 2019, 04:11 +0800, dowbh notifications@github.com, wrote:

I noticed that there is an overlay between the podium and the tower, which might be problematic. Because when I built the building's footprint (in AutoCad and ArcScene), there was no parameter that allows me to control at what z-axis level the tower will stand. Is there a way to make the tower stand "on" the podium?

Volume overlay

Another question I have is about the Type of system and envelope kind of setting. On the CEA interface, there are a series of types of wall, window, shade, etc., defined by T0, T1, T2.... I wonder what are those categories stand for? Is there a table of those categories that I can reference?

System Type

jimenofonseca commented 4 years ago

Not for the moment. CEA considers volumes attached to the terrain for now. What you can do is to change the height and number of floors of the podium tower so it goes until the desired height.

I hope this helps. On 14 Nov 2019, 1:41 AM +0800, dowbh notifications@github.com, wrote:

dowbh commented 4 years ago

So, based on what you suggest, the podium and the tower will have some portion overlapping with each other. Will that cause problems? Or will CEA subtract that overlapping volume?

dowbh commented 4 years ago

I successfully ran the simulation with the occupancy I want and with everything else set in default, but I got the "Temperature is out of bounds" error again after I changed the roof type from T4 to T6. I couldn't think of what might cause the problem because the simulation ran well before I changed the roof type. Can you take a look again for my input file? I attach it below.

Also, I am still wondering about the overlapping issue between the volumes of tower and podium, please reference back to our last discussion. Do you have any suggestions?

Is there a T6 in the database of technology/systems/envelopesystems/roof ? On 21 Nov 2019, 02:06 +0800, dowbh notifications@github.com, wrote:

I think T6 is "dark paint over plaster over concrete", if I was looking at the correct excel sheet.

@dowbh mind posting the error messagge you get? @reyery this could be a cell validation error in the interface, mind checking after @dowbh puts the error message in? thanks

dowbh commented 4 years ago

Hello Jimeno and @reyery

Here is the error message.

Clarifying the situation again, after I set the desired occupancy rate for all buildings, I ran the data helper -> solar radiation -> building schedules -> building energy demand. Everything worked well. And then I changed the type_roof in the architecture tag into my desired type T6, and I ran solar radiation ->building schedules -> building energy demand again, after which I got the error attached below.

@dowbh I wonder if you are having still the same problem in the latest version of CEA? we attempted to fix this issue in later december.
