Metering for energy efficiency refers to the measurement of quantities of a utility delivered (e.g., kilowatthours of electricity, cubic feet of natural gas, pounds of steam, gallons of water). Metering may also involve identifying times-of-use for the various energy sources, the instantaneous demand for energy, as well as identify energy use for a collection of buildings, individual buildings, rooms, or specific equipment (e.g., a boiler, chiller, or motor).
By way of metering, owners and managers have the ability to monitor energy usage, identify areas for improvement in efficiencies, and take advantage of opportunities to decrease usage during peak hours. By monitoring usage, owners also collect meaningful data to make better energy-related decisions, especially during negotiations with utility providers.
Energy metering and monitoring programs can make a significant difference in a company’s bottom line. The first step in improving energy management is measuring how, where and when you use all that energy. While metering alone does not save energy, the information from the meters, when acted on, can result in significant reductions. It provides the information that when analyzed allows the building operations staff to make informed decisions on how to best operate mechanical/ electrical systems and equipment. These decisions will ultimately affect energy costs, equipment costs, and overall building performance.
Kroeschell can help you track and compile how much energy your facilities are using. Once metering information is available, the facility executives can compare costs per square foot against similarly designed and used buildings. That information can provide a general sense of whether energy costs at a particular building are higher than average. If so, that building may well be a good place to look for energy-saving opportunities.
Reasons for metering vary by site; listed below are some rationale to consider for metering at your site:
- Monitor existing utility usage
- Verify utility bills
- Identify the best utility rate tariff
- Measure, verify, and optimize equipment performance
- Isolate utility/reimbursable use and costs
- Measure, not estimate, tenant energy use
- Diagnose equipment and systems operations
- Manage utility use
- Benchmark utility use.
