What should be prioritized in studio massing according to the hierarchy of action?

• A. Mitigation.
• B. Offsetting.
• C. Avoidance.
• D. Cradle-to-Grave assessment.

Answer: (C)

Avoidance takes priority because preventing impacts from arising in the first place is more effective than dealing with them after they occur. In studio massing, this means shaping the building form, orientation, and material choices so that energy use, embodied carbon, and other environmental burdens are minimized from the outset, rather than trying to fix problems later. If avoidance isn’t possible for some aspects, the next focus is reducing those impacts through smarter design and performance-minded decisions. Offsetting tries to compensate for whatever remains, but it comes after the effect has already happened and is therefore a secondary step. A cradle-to-grave assessment, meanwhile, is a tool for analyzing a product’s life-cycle impacts, not a design-action step in the hierarchy.
