NEW QUESTION # 31
Which of the following Is a measure of energy use intensity?
- A. Energy consumed per unit of floor space
- B. Systems with ENERGY STAR" requirements
- C. Daylighting and views
- D. The amount of electricity a wind turbine can produce
Answer: A
Explanation:
Energy use intensity (EUI) is a measure of energy use per unit of floor space. It is calculated by dividing the total energy consumed by the building in one year (measured in kilowatt-hours or kilo-British Thermal Units) by the total gross floor area of the building (measured in square feet or square meters). EUI is a useful metric for comparing the energy performance of different buildings or benchmarking against national averages. EUI can vary depending on building type, climate, occupancy, and other factors. Generally, a lower EUI indicates better energy efficiency and lower environmental impact.
