Perkins&Will

The 2024 City of Chicago Sustainable Development Policy establishes new sustainability requirements that influence how projects are designed, documented, and delivered. This workshop begins with an overview of the policy, including applicability, point requirements, compliance documentation, and the intent behind each major strategy. Participants will learn how to interpret the policy and identify which requirements are relevant to their projects.

The hands-on portion of the workshop is divided into two workflow modules. The first demonstrates advanced Revit techniques for modeling curtain wall systems with embedded performance data, including shared parameters for calculating window-to-wall ratio (WWR), assigning bird protection, generating orientation-based schedules, and creating quality assurance views for rapid design validation. The second introduces a Grasshopper workflow for panelized façade systems on complex geometry, showing how to automate panel classification, organize reporting by orientation and panel type, apply bird-safe frit strategies, and rapidly evaluate design alternatives. By the end of the workshop, attendees will have practiced reviewing policy goals, understanding the needed outcomes, and developing delivery strategies for meeting those goals.
