To run a project you will need an internet connection so the REopt™ Gem can access the REopt Lite API.
You’ll also need an API key from the NREL Developer Network. Copy and paste your key as an environment variable on your computer. Step-by-step instructions for creating env variables are found in the installation docs for your operating system.
GEM_DEVELOPER_KEY = '<insert your NREL developer key here>'
To run an example project incorporating REopt Lite functionality, use the URBANopt™ Command Line Interface (CLI).
