What is the triple bottom line in green architecture?

• A. Environmental performance only
• B. Environmental, social, and economic performance.
• C. Social and economic performance only
• D. Economic performance only

Answer: (B)

The triple bottom line means measuring a project’s success across three areas: environmental stewardship, social well‑being, and economic viability. In green architecture this translates to designing for energy and resource efficiency and low environmental impact; ensuring occupant health, comfort, accessibility, and community benefits; and achieving long‑term cost effectiveness, value, and financial return. This balanced approach prevents focusing on one dimension while neglecting the others—for example, a building that minimizes energy use but has poor indoor air quality or unaffordable maintenance isn’t truly sustainable. So the best choice captures all three performance areas together: environmental, social, and economic.
