Which certification emphasizes operational energy performance and indoor air quality in buildings?

• A. BREEAM
• B. Green Globes
• C. LEED (Leadership in Energy and Environmental Design)
• D. WELL Building Standard

Answer: (C)

This question centers on which certification most directly targets how a building operates in terms of energy use and the quality of the indoor environment for occupants. LEED is built around performance in energy and atmosphere, as well as indoor environmental quality. It includes credits for energy modeling and improving operational energy performance, plus measures that affect indoor air quality such as ventilation effectiveness, pollutant controls, and comfort in occupied spaces. This combination links how a building runs (its energy use) with how healthy and comfortable the air inside is, which is exactly what the prompt highlights. Other standards like WELL focus more intensely on occupant health and IAQ as a primary goal, while BREEAM and Green Globes also address energy and IAQ but LEED explicitly integrates operational energy performance with indoor air quality across its framework, making it the best fit for the stated emphasis.
