Results Viewer Overview

umi contains a built-in data viewer that allows users to quickly see simple aggregations of simulation results. This allows for exploration of simulations on a more sophisticated level than simple falsecolor views. The viewer is designed for fast feedback and trend spotting, not presentation-quality visualizations - for those, umi data should be exported and properly rendered in another program.

To access the results viewer, click the "Results" button in the umi toolbar:

The umi results panel will open. On the left, the list of metrics stored for the project are listed. Selecting a metric in this list plots that metric on the right side:

If no objects are selected in Rhino, one line is plotted for each umi simulation object for which the selected metric has been calculated. If any Rhino objects are selected, only data for those objects are plotted in the viewer. If a metric name is present in the list on the left but greyed-out and unselectable, that means that it is present for some selected Rhino objects but not all of them. Clicking on a plotted line will zoom to the corresponding object in the Rhino viewport, which is useful for identifying outliers.

The "Multiselect behavior" option below the metrics list controls the behavior of the viewer when multiple metric names are selected simultaneously (via Shift- or Control-clicking). When "Sum" is selected, the selected metrics will be added together. For example, the following image shows total heating (perimeter + core) for each simulated building:

When "Separate" is selected, each metric is plotted separately. For example, with a single building selected, the changes in its perimeter loads can be seen throughout the year:

In all cases, hovering the mouse pointer over a plotted line will display a tooltip providing more information.

Selecting the "Non-series" tab above the metrics list will show a list of all simulated metrics, not just time series metrics:

This list includes all time series totals as well as additional time-insensitive values like window-to-wall-ratios and mobility scores. To the right of each metric name, buttons exist to plot that metric on either the x- or the y-axis of a scatter plot. A third button allows the metric to be normalized by gross building floor area when visualized. As with series metrics, if any Rhino buildings are selected, only those buildings are shown, and otherwise all simulated buildings are shown.

If no metrics are placed on the x-axis, and a metric is placed on the y-axis, the scatter points for that metric are sorted:

If any metrics are placed on the x-axis, a standard scatter plot is displayed:

Multiple x-axis metrics can be displayed simultaneously. As with series metrics, hovering the mouse pointer over a point will show a tooltip with more information, and clicking on a point will zoom to the corresponding object in the Rhino viewport.

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.
