====== Case Study: Painting LA Streets White======
{{ ::examples:modelarea_whitestreets.jpg|LA Model Area}}\\

<WRAP centeralign>//L.A. model area to test the effect of white coated streets (552 m x 552 m).//</WRAP>

In this case study, one of LA’s oldest neighborhoods, Angelino Heights, was simulated in order to analyze changes caused by different surface materials. 

In order to understand long-term effects like underground heat storage, this simulation covers 6 days in June (18th to 23rd).

==== Download Model Files  ====

Here you can download the two L.A. models, one with dark streets and the other with white coated streets plus the associated .SIMX files. This project also uses a Project Database which included in the download.

==== Download Sample Results ====

The model results below have been calculate using the full version of ENVI-met (BUSINESS/SCIENCE, V5.5.). The simulation time with an AMD Ryzen Threadripper 2990WX with 32 cores, a maximum clock speed of 4.2 Hz and 128 GB of RAM is approximatly 372 hours. The outputs generated by the free LITE version contain much fewer data. **This is a large dataset covering 6 simulated days.**

<WRAP center round info 60%>
There are always two sets of files, one for the base scenario with classic dark streets ("//AsphaltRoad...//")  and one with the white-coated streets ("//WhiteStreets..//"). To compare the two and analyse the effects of white coated streets, you need to download both sets and extract them to your disc.
