In a master metered building, which action do BPI guidelines recommend for tenants?

• A. Buy energy efficient appliances, but not necessarily ENERGY STAR
• B. Provide tenants with ceiling fans instead
• C. Rent cooling units from building management
• D. Purchase Energy Star air conditioners.

Answer: (D)

Energy efficiency in a master metered building is about reducing the overall energy use that affects the shared bill. Air conditioning often drives a large portion of that consumption, so choosing equipment that minimizes energy use makes a real impact. ENERGY STAR air conditioners meet standardized efficiency criteria, so they provide the same cooling performance while consuming less electricity. This combination of reliable efficiency and measurable savings aligns with what tenants and building operators aim for in a master-meter setup: lower energy bills and less peak demand. The other options don’t carry the same guaranteed efficiency or direct impact on energy savings—relying on ceiling fans, or on renting units from management, or buying non–ENERGY STAR appliances, won’t ensure the same verifiable efficiency benefits.
