Professional Practice & Everyday Jargon
Charrette
An intensive, multi-stakeholder design workshop — typically multi-day with iterative feedback loops — used in planning and sustainable-building projects to align goals early.
Expert review openNo editor-accepted expert review yetDefinition
A structured, collaborative design process in which all stakeholders work intensively over a compressed period — often several days — through cycles of drafting, presentation and feedback to produce an agreed plan or design. The term comes from the carts (charrettes) that collected students' final work at the École des Beaux-Arts in nineteenth-century Paris.

Sustainability charrette for early goal alignment (GHG, water, waste); timing before site selection/feasibility.
Overview
What it means
In sustainability practice the charrette is the standard instrument of integrative design: bringing architects, engineers, owners, operators and community members together before decisions harden.
Green-building frameworks reward it — LEED's Integrative Process credit is commonly satisfied through an early sustainability charrette that sets targets for energy, water, materials and wellbeing, ideally before site selection or feasibility locks options.
The National Charrette Institute codifies the method (structured, values-based, with feedback loops), and guidance on "what a charrette is not" warns against one-off brainstorming sessions mislabelled as charrettes.
How it is used
Design teams run sustainability charrettes at project kickoff; urban planners use charrettes for community visioning; facilitators structure iterative loops with cross-disciplinary "charrette teams"; outcomes feed goal-setting documents and certification submissions.
Why it matters
Charrettes are how sustainability enters projects at the point of maximum leverage — the integrative-design ritual that turns diffuse green ambitions into committed targets.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
