Hello,

I am just wondering if someone could clarify how the overheating user interface works in UMI, or point me towards the documentation as I couldn't find it when I looked.  I am just confused about how to operate it and what it gives me back. 

You have the max comfortable temperature (pretty self explanatory), which I am assuming is the threshold for overheating if internal temps rise above that.

Next there is the Affected Floor area, and this is the part that is confusing me.  Is it saying how many hours in a year that an area of this size anywhere in the building overheats? 

I imagine it is implemented this way since there are no actual thermal zones defined in the building like a typical model, but how then would you make an accurate assessment of overheating in UMI that you could compare to a "typical" simulation output?

Thanks for your help!

Cheers,

Wes

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.
