There are several rankings and benchmarks for corporate energy efficiency and corporations can perform an energy audit to see where they can improve with their energy usage. Corporations should look into how many kilowatts they use per square foot and how much gas or BTUs are used per square foot. Each country will have average values and recommended values for being efficient.
If you are looking to improve your company’s energy usage you can look into the different products available as each vendor will have information about its products’ energy consumption. For example, glass companies will provide information on their products’ solar heat gain and U-value, and so on.
