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.
Many more corporations are creating positions that deal specifically with energy management and many times there is compensation or benefits for those corporations that have good energy performance. There are several different ways in which corporations can make changes to their energy usage and ultimately enjoy big energy savings.
You want to make sure that your building is properly maintained as this keeps it running as efficiently as possible. Small changes can actually cause big changes in energy consumption. One such example is not running the air conditioning at night if no one is in the building. Also you can go through a retro-commissioning process to get your building back to its original state.
Steam systems are frequently an issue with energy usage as they are not maintained well. Steam traps tend to be used to deal with condensation but these can easily become stuck open and transfer the steam back into the boiler. This wastes a lot of heat as the steam goes back into the system and does not heat the building. You need to make sure these are replaced regularly and maintained well.
You also want to optimize your HVAC systems and these can account for 20 percent or more of all energy used in a building. And lastly, you might want to look into thermal energy storage or heat recovery options.
