Commercial projects can take years to plan and construct so careful planning can be essential for a successful project outcome. Properly facilitated design charrettes can add new insight and additional value to commercial projects by involving selected professionals to the meetings.

There is a free project platform for residential and commercial projects available from ARCAT* and here is the link to check it out: https://www.arcat.com/

*DesignCharrette.com is not affiliated with ARCAT in any manner. 

Meanwhile, sometimes a quick read of a suitable reference is all that's needed to help get things started...

One free resource is the Handbook for Planning and Conducting Charrettes for High-Performance Projects produced by National Renewable Energy Laboratory (NREL). (PDF download)
