Step 1 of getting your Energy Management System (EnMS) up and running is deciding on “What” and “Where” you want to measure/monitor and “How” you want to manage your consumption. This is often decided by the significant energy usage at your installation.
Possible “What” and “Where” you want to deploy measurement devices are Electrical DBs, Water Metering, Gas Metering, Lighting Intensity, Area Temperature, Compressed Air and HVAC.
You can define “How” to do Energy Management by either “Area” or “Process” or a combination of both. The only rule here is that you need to cover significant energy usage.
STEP 2 – Get Communication Working
Step 2 involves establishing a communication link between your deployed measurement devices (Step 1) and your control system (Step 3). RS485 cabling is the most common communication method but increasingly RF and TCP/IP are being used.
It is best (if possible) to piggyback on an existing communication system at your installation such as LAN, Wi-Fi, Profibus, etc. Using existing communication systems reduce the cost and effort required to get your EnMS up and running. Additionally you don’t have to independently maintain the communication system.
If this is not possible, select a suitable communication method based on your budget and installation condition. A combination or hybrid communication network, which is optimized for the installation, can also be deployed.
Step 3 is about setting-up your control system to perform data acquisition from installed measurement devices (Step 1) thru the communication network (Step 2).
You need to determine the parameters that you need to log and your logging frequency. The EnMS objective plays an important part in deciding the required parameters and logging interval.
This step also involves setting up the roles and responsibilities of your EnMS team members. Access and features can be selectively assigned to individual EnMS team members based on their role.
Most importantly, you setup your EnPI (Energy Performance Indicators) benchmarking frequency and parameter for each process / area in your EnMS.
Step 4 is the final step in getting you EnMS operational. Here the face of the EnMS is setup and this decides the success of engagement with your EnMS.
Based on your EnMS objectives, you can configure various analytics charts, tables, reports and alerts. SMS and email alerts are features that enable a fully automated EnMS environment.
Analytics feature in i3EnMS enables display and generation of reports based on “Consumption Trend Monitoring”, “Consumption Trend Comparison”, “MD Trend Monitoring”, “MD Trend Comparison”, “Area/Process Consumption & Trend”, “Consumption Breakdown” and “Energy Cost Analysis” among others.
The last activity is to configure the broadcast of EnMS data on external LCD TVs, both single and multiple throughout the organization (either showing total or selective area Energy Performance). This is an important feature that enables the development of “Energy Efficient Culture” in the organization, as everyone will have access to data on their consumption.
