the typical usage for a given timeframe and only allows data within a percentage range of that profile.
In order to make cost savings, energy managers also need the ability to verify the accuracy of utility bills. An energy management software tool can take information from a bill, compare it to actual consumption taken from the meter, and then notify users of any inconsistencies. This may be one of the easiest ways to save costs and achieve buy-in from your finance department !

baseline which reflects the varying factors that affect energy use in your business. Depending on the business, this may include variables such as production output, occupancy, time of year, temperature etc.
To achieve this, an regr ession analysi s tool is required to build an accurate profile from historical data, taking into account all the driving factors that have an impact on energy consumption .

Once accurate targets have been set, the next challenge is to identify where the savings to achieve these targets can be made. An effective place to start is to break down energy consumption by location, whether that’s site, building, floor or department. This is possible with analytics software that enables you to compare normalised consumption for each location, so that factors such as building area, volume and production are taken into account to ensure a fair

practices of the highest performing sites, and also motivate personnel in lower performing sites to improve.
To identify inefficiencies at a more granular level, such as a faulty piece of equipment, consumption profiles can be constantly monitored on regularly updating dashboards and using
visualisation such as surface-mapping graphs, so that anomalies can be found .
3. WHEN DO IN ERVENE WHEN DO I INTERVENE?
Energy usage can legitimately vary due to a number of factors, so it’s therefore important to understand at what point to take action. Only with effective profiling can this be achieved, for example a spike in consumption due to an increased production output is to be expected, therefore an energy management system needs to be able to intelligently recognise and normalise the increase.
With a multi-variable regression model in place users can then identify th e genuine anomalies in energy data and react accordingly. To maintain this at the lowest impact to the user, alarms can be set up so that a notification via email is sent when consumption is at an
unexpected level. The tolerated limits for alarms can either be set up manually or

always a challenge, but it’s virtually impossible without the tools to analyse, monitor and target energy data to inform where greater efficiency can be achieved. An energy analytics tool can help you choose where to place those additional meters, as well as monitor their performance to identify savings. Importantly, energy management software tools also offer the full
reporting capabilities to track and verify savings to assure stakeholders of a return on investment and ultimately give you r business the confidence in your decisions to ensure future investments in energy initiatives.
