Plants managers who want to reduce the consumption of energy in facilities can create a plan that addresses all areas of energy consumption.
National Instruments Corp. (NI), an Austin, Texas-based automation products vendor, suggests using these guidelines for determining energy consumption and addressing potential energy savings strategies: NI estimates that plants can achieve a 10 percent to 25 percent savings in energy consumption at facilities by implementing this plan. NI notes, however, that an engineer with a keen eye for energy savings is hard to find.
- Find inefficient systems and faulty systems and repair them
- Adjust clock-controlled systems for shorter operational time and ensure systems are not working on holidays
- Lower general energy usage
Find the rate tariff best suited for the energy profile at your place of business. In order to implement energy facility
management, several things are needed:
- Data logging a few of the most important equipment parameters such as electrical usage, gas usage, and forward and return temperatures. While sampling may be every five seconds, a good periodic data storage is 15 minutes, giving 96 registrations per 24 hours.
- Automatic collection of data, storage, displays and Web access to data
- Automatic reports to provide overview
- Automatic calculation of least-costly rate tariff
- An energy engineer with a keen eye to figure out if energy is wasted or should be used differently. The engineer should be able to calculate savings based on change scenarios.
- A contact within the facility who has the power to enforce changes.
