What is 'sustainability-based design' and how can it be evaluated in the design process?

• A. A method to maximize profit without regard to environment.
• B. A process only used after construction is complete.
• C. A design approach prioritizing environmental performance, energy efficiency, and social responsibility; evaluation via metrics such as energy use intensity, daylight metrics, LCA.
• D. A requirement to minimize material usage regardless of function.

Answer: (C)

Sustainability-based design is a design approach that prioritizes environmental performance, energy efficiency, and social responsibility throughout a building project. It’s evaluated during the design process by setting measurable goals and testing options through models and simulations. You’d typically look at energy-use intensity from energy modeling to compare how different designs perform, use daylight metrics to ensure good natural lighting and reduce reliance on artificial lighting, and apply life-cycle assessment to weigh the environmental impacts of materials and assemblies over their entire life. This evaluation happens iteratively as ideas are developed, refined, and balanced with cost and function, not after construction. It’s not about maximizing profit at the environment’s expense or minimizing material use without regard to function; it’s about making informed, quantifiable choices that improve overall sustainability.
