I am really looking forward to test this very interesting tool!

It can only be a success as DIVA ;)

Thanks Daniel! Umi will be available publicly after the Sustainable Urban Design Symposium at MIT. :)

Hi, today I just joined. I found this via Diva and happy to test it tonight. I got a perfect application so the timing could not be betterI am very excited and hope that my enthusiasm remain the same at the end of my task. :)

Hi Michal,

We would be more than glad to support any of your questions, and we welcome all feedback.
Thanks a lot! :)

Hi,

It looks very promising. Some questions Thermal.:

1. How to move files/project between PC whan need to be copied?

2. I managed to het thermal simulation OK. In results I can not identify which building is which

-Building Energy Consumption - each 3D building is coloured to this scale?

- Building EUI by Type and WWR? I have 4 circle I guess that represent my building? 

- WWR is window to wall ratio?

- Average Template Building Monthly Energy Consumption is some of specific template building type and  calculated average?

Some questions Daylight:

I really like the fact that we can see numbers above buildings.

3. I could not get results to present there, and got it blank not sure why?

3a. I can see image is very nice, Why do you present radiation in MLux and not kW/m2?

4. I could not get any results for Design Accessibility Maybe got something wrong following   Step 2: Modeling Streets, Buildings and Amenities . I attached rhino file could you please comment?

4a. I can see in Rhino command line messages: No walk found for line at position 4. Are end points isolated?

Attachments:

Summary:

It is very positive as I could get so far... right now just need to find some solution for those two problems and I think it is great. I would recommend to get new layer with Legend and Units so it is clear what we see. 

Great work, congratulations!

Hi Michal,

Nice to see you on this venue too.

1. How to move files/project between PC whan need to be copied?

Good question. If you don't have any custom template data, you can just move the Rhino file. If you have custom template data, also bring along the c:\Urban-Modeling\Building Templates\ folder too.

2. I managed to het thermal simulation OK. In results I can not identify which building is which

Thanks for the feedback. In fact, we were just discussing that today.

-Building Energy Consumption - each 3D building is coloured to this scale?

Yes.

- Building EUI by Type and WWR? I have 4 circle I guess that represent my building? 

Exactly -- there is a point for each building simulated.

- WWR is window to wall ratio?

Yes, the normalized just means it is area-weighted across all wall orientations.

- Average Template Building Monthly Energy Consumption is some of specific template building type and  calculated average?

If you have multiple custom templates assigned (say one for residential and one for commercial), you will see the average for each template type displayed. Since all four of your buildings use the same template, this is just the mean monthly EUI for your buildings. 

Hope that clears up some questions about the thermal components!

Best regards,

Alstan

 

 

Thanks for reply. Can you aslo look at my Daylight questions,

You'll be surprised to hear that I don't work on the Daylight components of Umi. Timur will reply to that portion, I am sure.

All the best,

Alstan

Hi Michal,

Your questions were listed under Daylight, so I did not reply because it is not in my domain as a developer for umi, so I apologize for the delay, I just noticed them.

Both your issues had one problem, you modeled streets isolated from the network! Please check the model, you will find that you have on the "streets" layer curves that outline the main building and the courtyards, please remove them and re-run. In addition to this please place any buildings you want to analyze for Walkability on the "buildings" layer. The blockage layer has a building that seems like you want to get analyzed based on the streets network, perhaps you can place it on the buildings layer for this analysis.

Let me know if all is well!

4. I could not get any results for Design Accessibility Maybe got something wrong following   Step 2: Modeling Streets, Buildings and Amenities . I attached rhino file could you please comment?

4a. I can see in Rhino command line messages: No walk found for line at position 4. Are end points isolated?

Hi Michal,

It is hard to say why in your case the results viewer stays blank.

I highly recommend that you use the Urban Daylight toolbar as shown in UserGuide/UrbanDaylight/ExampleFile. Also have a look at the Builder, Settings and Results Viewer section. There is a more detailed results visualization and you will have a lot more control over your simulations. E.g. in your screenshots the indoor mesh density looks much too low. I recommend something around 1m. Radiation is simulated in lux due to Daysim. 

Best,

Timur

In Short

Umi is a Rhino-based design environment for architects and urban planners interested in modeling the environmental performance of neighborhoods and cities with respect to operational and embodied energy use, walkability and daylighting potential. Since 2012, Umi has been  developed by the Sustainable Design Lab at the Massachusetts Institute of Technology with support from a National Science Foundation EFRI_SEED project, the MIT Energy Initiative, the Kuwait-MIT Center, the Center for Complex Engineering Systems (CCES) at KACST and MIT, Transsolar Climate Engineering and United Technologies Corporation. Further tool developed is now also being conducted at the Environmental Systems Lab at Cornell University.

A first public version of Umi was released during a public symposium on Sustainable Urban Design on May 6th 2013 at the Massachusetts Institute of Technology. Version 2.0, which also includes an embodied energy module, was released on November 7th 2014.
