Developers and project teams are being asked to deliver lower-carbon, healthier buildings while keeping pro formas intact and schedules moving. The biggest barrier is rarely a single technology. It is the gap between design intent and a financeable scope. This session is a candid, highly practical discussion about how real projects stack the deal so decarbonization becomes investable. Panelists will pull back the curtain on the mechanics that determine whether incentives and financing actually land: early feasibility alignment, documentation timing, underwriting assumptions, value engineering pressure, and the hidden handoffs between developer, architect, and engineering teams that either protect or unravel performance scope. The panel brings four complementary lenses. A market-rate developer shares what makes measures pencil from an underwriting and tenant value perspective. A sustainable investment expert addresses incentives, compliance, and risk frameworks that shape capital access. An architect brings the delivery reality of how envelope and systems decisions become durable scope, and what it takes to keep performance intent intact through design development and construction. A mechanical engineer with finance fluency moderates and translates the conversation into a repeatable workflow. Attendees will gain a clearer, more actionable view of the capital stack landscape including incentives, tax credit adjacency, green lending products, and PACE, plus the sequencing required to avoid common failure points that quietly kill high-performance deals. A short “capital stack clinic” segment will let participants test the framework against a sample project scenario and learn how different deal types change the approach.
