Which performance metrics are commonly used in BERDE for energy?

• A. Land-use density and transit access
• B. Energy use intensity (EUI), peak demand, and system COP/EER, lighting power density, and daylighting metrics.
• C. Noise levels, acoustic performance, and vibration
• D. Water balance, groundwater recharge, and soil carbon

Answer: (B)

In BERDE, energy performance is assessed with metrics that directly quantify how much and how efficiently energy is used in a building. The main indicators include energy use intensity (EUI), which expresses annual energy consumption per unit of floor area and lets you compare buildings of different sizes on a like-for-like basis. Peak demand measures the highest electrical load the building requires at any point, which matters for sizing systems and managing utility costs. System COP (coefficient of performance) or EER (energy efficiency ratio) evaluates how efficiently heating and cooling equipment perform, with higher COP/EER values indicating better efficiency. Lighting power density tracks the amount of energy used for lighting per area, guiding design choices to minimize lighting energy. Daylighting metrics assess how effectively natural light reduces artificial lighting needs, contributing to energy savings and occupant comfort. These energy-focused metrics together cover consumption, peak load, system efficiency, and lighting strategy—precisely the aspects BERDE targets for energy performance. Other options refer to site accessibility, acoustics, or water/soil considerations, which are not energy metrics.
