Collectively establish meaningful sustainable objectives for a project and outline the process for achieving them before the start of design. All participants focus on ideas for efficient use of energy and resources in the new building.

The entire team (including the architect/designer, engineers, energy modeler, technical advisors, general contractor, user group representatives, representatives from planning department and utilities, facilities manager, facilities director, financial manager, purchasing/leasing agents, and owner) meet for 1 to 2 days. Consider splitting the charrette into “energy” and “broader green” goals or “skin in” and “skin out.”

Significant preparation is required. The greater the spirit of collaboration, the better the results are likely to be. All participants need to be well informed about the goals and be willing to work in a collaborative process. Establishing specific goals is crucial and the client needs to play a major role in setting goals. Team spirit, knowledgability, experience, and diversity of the team are necessary factors.

The economic gains from a successful eco-charrette are derived from efficient use of energy and resources.

A charrette post-analysis report and follow up is required to summarize project goals, set directions and clarify next steps for the team. This report is prepared by the architect with input from the owner.

For best results, each participant does some research prior to the charrette to understand how his/her systems fit into the overall project goals and to formulate some innovative approaches. The facilitator may interview the client before the charrette to determine environmental and energy efficiency goals. A champion is needed on the owner’s side to actively support the integrated design process.
