### Identifying High Performers
</br>
As an alternative way to explore a parametric design space, the parallel line coordinate graph below can be a useful tool. The left columns of the graph represent parametric inputs, including façade orientation, window-to-wall ratio, window U-value, shading, and thermal mass. The columns on the right display key output metrics including daytime comfort percentage, cooling degree hours (CDH), heating degree hours (HDH), and heating + cooling degree hours (HCDH). Each line on the graph, passing through each input and output columns, represents a simulated scenario. By limiting the field of results to those that provide passive thermal comfort for a minimum of 65% of the year, and selecting a façade orientation which is of interest to the user, we can identify all of the envelope combinations able to satisfy our comfort criteria, rather than limiting the design to a single optimal case.
