Which BERDE stage is described as the operational phase involving performance and ongoing sustainability practices?

• A. Stage 2 - Implementation
• B. Stage 1 - Design
• C. Berde - Districts
• D. Stage 3 - Operational

Answer: (D)

The concept being tested is identifying the phase focused on how a building performs once it’s in use. The Operational stage is the period after construction when actual performance is measured and sustained through ongoing practices. It involves monitoring energy and water use, indoor environmental quality, waste management, and the maintenance and improvement of sustainability efforts over time. This is where commissioning, post-occupancy feedback, and data-driven adjustments occur to keep meeting targets. It differs from the earlier stages—design, where goals and features are planned, and implementation, where the building is actually constructed and systems are installed. The option about districts isn’t a stage in this lifecycle, so it doesn’t describe the ongoing operation phase.
