EWUtilityBilling
  Cost Allocation and Utility Billing System

Despite the name, EWUtilityBilling does a lot more than provide utility bills. More than cost allocation. EnergyWitness™ is the only system combines the billing and meter data of typical utility billing systems with operational (BAS) data. Other utility billing systems can't tell you why costs are high without requiring you to add more and more meters—which makes those systems cost prohibitive and they still can't identify what's going on in many cases. By connecting your utility bills to all the operational data, EWUtilityBilling gives you a direct path from the invoice to the data behind it so that utility costs and consumption can be managed.

Utility Bills that Help Tenants Manage Energy Costs

Utility Billing System diagram
Although facilities vary, in this diagram electricity, water, and natural gas are purchased, and chilled water and steam are generated. EnergyWitness collects all consumption and billing data from the utility meters, plant operations, and buildings, then can generate consolidated bills and General Ledger reports.

EWUtilityBilling is designed to consolidate energy costs for all purchased and on-site generated utilities, and allocate the costs into a single bill for the tenant (department, cost center, building). Tenant's bills include the cost, consumption, and rate structure information, and also trend charts showing a graphical picture of operations (not just additional data from sub-meters) for the month. This gives tenants a starting point to actually manage their energy usage and costs.

Billing information is just a starting point. Tenants can see why their bills change, whether it is fluctuations in consumption or unit pricing. But what then? The only answer other systems can give is to throw more meters at the problem and they can provide the same, inadequate information at a slightly more granular level. Not so with EWBillingUtility.

Because EWUtilityBilling is an integrated component of EnergyWitness, and connects all the operational data to the utility bill, you can investigate and determine why consumption changes. Tenant bills are a roll-up of control and monitoring data—not just meters but your BAS(s) and METAR data too. The data will show if changes were due to weather, usage patterns, control changes, faulty equipment, or something else.

Finally, tenants can actually do something with their energy bill besides moan that it's too high. You can produce tenant bills with trend charts of air handlers, cooling consumption, operational cost or whatever metrics are meaningful to your tenants. Charts can show daily, weekly, or monthly patterns, show the impact of weather---actionable information so tenants can make changes to affect their costs. Beyond that, EnergyWitness provides the tools to perform detailed diagnostics of operations that influence the utility bills. And it's all possible because we have the data.

Data Drives Everything

Operational data is what enables EWUtilityBilling to perform accurate cost allocations. It  is using all the data, not just utility meters and bills (although obviously that's part of it). By combining the billing information with operational data from building automation systems, advanced metering systems, space planning systems—everything stored in EWDataWarehouse—we can more accurately identify costs down to the space level. Departments that have high energy demands will pay for their impact on utility costs (and know why costs are high and where the energy is being used), and departments with low energy needs will stop subsidizing them.

It's not just about allocating costs of purchased utilities—generated utilities are equally a part of the equation. EnergyWitness tracks rate structures, both from utility companies and internally developed rates. It supports rate structures of any complexity for facility generated utilities, including options such as time-of-use pricing.

Having a historical record of billing information is valuable. Having those records accessible beyond a departmental spreadsheet, and having access to historical changes in rate structure and operations is invaluable. And we mean historical---the data will be around for 20 years. so, you can go back as far as you need to and see changes in consumption, rates (i.e. $/kWh), and other billing determinants (taxes, fuel charges, etc.). Again, because we tie the bills to operational data, you can see the impact of changes ranging from someone lowering a room thermostat to a change in chiller setpoint.

How is all this possible? (Everyone together this time.) Data.

Uses of Cost Allocation

There are a couple important benefits to accurate energy cost allocation.

EWUtilityBilling is everything you need to convert your facility power plant from an overhead expense to a profit center. This has much greater implications than internal budgeting, as many organizations (especially universities) are struggling to find new ways to fund the maintenance of building assets. By making your power plant a profit center, you the leverage to issue bonds using your internal utility operation (bills and rates) as collateral, funding maintenance and improvements to building/campus assets on a self-maintaining basis.

For organizations (typically research hospitals and universities) involved in government funded research there is an opportunity to recover more of your energy budget through research grants. Because EWUtilityBilling can accurately identify energy costs for research space (typically heavy users) you can accurately build that cost into grant proposals and ensure your organization can maximize available funding opportunities.
