Letter A is the correct answer from the choices. Energy Star is a screening tool in determining a company’s building performance when it comes to using and saving energy. When a building is awarded by Energy Star with high energy performance, it can boost up the company’ reputation.
The median is a score of 50 but if a building scores 75 or higher, it can be dedicated with an Energy Star certification. The score helps in normalizing the business activity; the climate, hours, and workers, indicating the energy performance’s level, evaluating the billed energy data, and comparing building among the national population. Companies must not worry for it will never explain why their building has a poor performance thus they can improve them.
