RELATED APPLICATION This patent application claims priority to Patent Application Ser. No. 60/959,318, filed Jul. 12, 2007, entitled Energy Management System User Interface.
TECHNICAL FIELD The present disclosure relates generally to utility management and more specifically to a system and method for managing utility resources based on utility service points.
BACKGROUND Traditional systems for managing utility resources allow users to store invoices received from vendors. In addition, these systems may permit users to search for invoices associated with a particular date or a particular account. These traditional systems, however, do not store audit information, supply information, and efficiency information for customer sites. In addition, these systems do not formulate strategies for reducing utility costs of a customer based on audit information, supply information, and efficiency information. As a result, these systems have proven unsatisfactory for assisting customers in managing utility costs.
SUMMARY In accordance with the present disclosure, the disadvantages and problems associated with prior utility management systems have been substantially reduced or eliminated.
In some embodiments, a system comprises a memory that stores a plurality of utility invoices associated with one or more customers. A particular utility invoice comprises a bill for a utility resource provided by a utility vendor to a particular customer. The memory further stores supply data associated with the plurality of customers, the supply data comprising a plurality of contract terms from at least one contract between the utility vendor and the particular customer. The memory further stores site data associated with the plurality of customers, the site data comprising one or more characteristics of a site of the particular customer. The system further comprises a processor that determines at least one strategy to reduce utility costs of the particular customer, the determination based at least in part on the particular utility invoice, the supply data, and the site data. The processor may generate a graphical user interface that displays the at least one determined strategy.
In some embodiments, a system comprises a memory that stores a plurality of usage values. A usage value may be based at least in part on usage of a utility resource measured by a utility meter having a meter identifier. The memory may store a plurality of service point identifiers and a plurality of account identifiers associated with one or more utility accounts. A particular service point identifier may represent a physical location of at least one utility meter. Each service point identifier may be stored in association with one or more usage values. The system may comprise a processor communicatively coupled to the memory. In response to a request comprising a particular service point identifier, the processor may retrieve one or more usage values from the memory based at least in part on the particular service point identifier in the request. The processor may generate a graphical user interface that displays the one or more retrieved usage values.
In some embodiments, a system comprises a memory that stores weather data associated with a site. The system further comprises a processor that determines a balance point of the site based at least in part on the weather data. The processor may determine an amount of utility usage at the site during a particular time period. The processor may normalize the amount of utility usage based at least in part on the balance point and the weather data. The processor may generate a graphical user interface that displays the balance point and the normalized amount of utility usage.
Various embodiments described herein may have none, some, or all of the following advantages. One advantage is that the system may comprise a utility management platform that monitors and evaluates information regarding invoices, supply contracts, efficiency, and/or audits associated with customer sites. Based at least in part on this information, the platform may determine strategies for reducing the utility costs of a customer. In some embodiments, these strategies comprise fixing equipment (e.g., a malfunctioning meter) and/or correcting billing errors (e.g., a meter reading error or a miscalculation of a utility rate). According to certain embodiments, these strategies may comprise negotiating particular contract terms, changing the operating parameters at a customer site, and/or applying for particular credits and/or refunds from a vendor. The platform may guide a customer in implementing these strategies to reduce utility costs and/or to increase the efficiency of a customer site.
Another advantage is that the system may comprise invoice databases that are indexed according to service point identifiers. Indexing a database according to service point identifier may provide long-term advantages over indexing the database only according to account number and/or meter identifier. For example, a customer occasionally changes an account and/or replaces a meter associated with a customer site. The new account may be assigned a new account number and the new meter may be assigned a new meter identifier. However, obtaining a new account or a new meter does not change the service point identifier for a related service point. If the database is not indexed according to service point identifier, then a query based on the new account number and/or the new meter number may not retrieve historical invoice data that is associated with prior accounts and/or meters. Accordingly, by indexing the database according to service point identifier, the system may more accurately and/or efficiently respond to queries for historical invoice data.
Another advantage is that the system may normalize utility usage with respect to weather at a customer site. In some embodiments, the system may provide a graphical user interface that graphically illustrates normalized usage data for a customer site for a particular period of time. The graphical presentation of normalized usage data may permit a user to easily identify problems unrelated to weather that may contribute to changes in utility usage at the customer site.
Another advantage is that the system may determine the emissions of pollutants caused, directly or indirectly, by utility usage at a customer site. According to certain embodiments, the system may generate a graphical user interface that illustrates emissions caused by an increase or decrease in normalized utility usage at the customer site. The user interface may illustrate how the activities of the customer, rather than the weather, are affecting the level of emissions caused by the customer site.
Other advantages will be readily apparent to one skilled in the art from the description and the appended claims.

In some embodiments, supply contract 22 is a fixed rate contract, variable rate contract, or blended rate contract. A fixed rate contract may refer to supply contract 22 in which the price of utility resource 14 is fixed for a period of time (e.g., one year, two years, the term of supply contract 22, etc.). A variable rate contract may refer to supply contract 22 in which the price of utility resource 14 is set periodically (e.g., weekly, monthly, etc.) based at least in part on the price that vendor 20 pays in the wholesale market for utility resource 14. A blended rate contract may refer to supply contract 22 in which a portion (e.g., half) of the rate for utility resource 14 is fixed for the term of supply contract 22 and the remaining portion (e.g., half) of the rate for utility resource 14 periodically reset by vendor 20 based at least in part on market prices.
In some embodiments, supply contract 22 may be customized according to characteristics of vendor 20 and/or market conditions. For example, supply contract 22 may be a rate cap contract in which vendor 20 agrees to provide utility resource 14 to customer 30 at the market price with a guarantee that the rate will not rise above a certain value regardless of the current market price. As another example, supply contract 22 may be a fixed-bill contract (e.g., weather-protection contract) in which vendor 20 guarantees that customer 30 will not pay more than a fixed amount for utility resource 14 over a given time period (e.g., year, two years, etc.). The fixed amount that is charged to customer 30 may be based at least in part on the usage pattern of customer 30 over the previous period (e.g., year, two years, etc.) and adjustments for weather. As yet another example, supply contract 22 may be a fixed volume contract in which vendor 20 and/or customer 30 estimates the periodic (e.g., monthly, quarterly, etc.) utility usage 26 of customer 30 based at least in part on past utility usage 26, and vendor 20 procures the estimated quantity of utility resource 14 on behalf of customer 30. Customer 30 may be financially responsible for the difference between the estimated utility usage 26 and the actual amount of utility resource 14 purchased by vendor 20 for customer 30 on the spot market. Vendor 20 may calculate the difference between the estimated and actual utility usage 26 of customer 30 each hour, half-hour, and/or according to any suitable interval of time. Thus, supply data 62 in memory module 46 may comprise information regarding any number and/or combination of supply contracts 22.
In some embodiments, memory module 46 stores site data 36. As explained above, site data 36 may comprise information regarding the operation, performance, and/or maintenance of customer systems 28 at each site 24 associated with system 10. Site data 36 may comprise information regarding the equipment in customer system 28, the operating schedule of customer system 28, the quantity of utility resource 14 consumed by customer system 28, and/or the operating conditions associated with customer system 28.
According to certain embodiments, memory module 46 stores invoice data 64. Invoice data 64 may comprise information regarding past and current invoices 16 from vendors 20 to customers 30. Invoice data 64 may comprise any suitable billing information such as, for example, utility usage 26 and utility cost 12 for one or more billing periods. Invoice data 64 may comprise delivery fees, customer fees, supply fees, taxes, and/or any suitable information.
In some embodiments, memory module 46 stores audit data 66. Audit data 66 may comprise any suitable information regarding audits that platform 40 may perform on behalf of customers 30. In some embodiments, platform 40 may audit supply data 62, site data 36, and/or invoice data 64 of customer 30 to determine strategies 18 for reducing utility costs 12 and/or increasing efficiency of customer 30. By auditing supply data 62, site data 36, and/or invoice data 64, platform 40 may identify problems such as, for example, a malfunctioning meter 74, a meter reading error, a miscalculation of a utility rate, a miscalculation of taxes, and/or a billing error. Platform 40 may determine any suitable strategy 18 for reducing utility costs 12 and/or increasing efficiency of customer 30. In some embodiments, strategy 18 may be for customer 30 to renegotiate supply contract 22 and/or execute a new supply contract 22 that includes a particular type of rate. For example, strategy 18 may recommend that customer 30 switch from a fixed rate contract to a blended rate contract. According to certain embodiments, strategy 18 may be for customer 30 to change operating parameters of site 24. For example, strategy 18 may recommend that customer 30 deactivate the air conditioning system at site 24 during weekends. In some embodiments, strategy 18 may recommend that customer 30 apply for exemptions and/or credits from vendor 20. For example, strategy 18 may recommend that customer 30 apply for credits from vendor 20 by switching from commercial status to residential status. By auditing supply data 62, site data 36, and/or invoice data 64 of customer 30, platform 40 may determine any suitable type and/or combination of strategies 18 for reducing utility costs 12 and/or increasing the efficiency of customer 30.
Although FIG. 1 illustrates separate memory modules 46 that store supply data 62, site data 36, invoice data 64, and audit data 66, it should be understood that supply data 62, site data 36, invoice data 64, and/or audit data 66 may be stored in one memory module 46, in multiple memory modules 46, in manager memory 48, and/or in a suitable configuration of memory devices.

GUI 72 may provide user 68 with an efficient and user-friendly presentation of supply data 62, site data 36, invoice data 64, and/or audit data 66. GUI 72 may comprise a plurality of displays having interactive fields, pull-down lists, and buttons operated by user 68. In one example, GUI 72 presents relevant invoice data 64 to user 68 and conceals the remaining information to reduce visual clutter. Then, upon receiving a request from user 68, GUI 72 expands the visual representation of invoice data 64 to display account information, contract information, and/or other suitable information. GUI 72 may include multiple levels of abstraction including groupings and boundaries. It should be understood that the term graphical user interface may be used in the singular or in the plural to describe one or more graphical user interfaces and each of the displays of a particular graphical user interface.
Each client 70 may be associated with one or more users 68. User 68 may comprise any individual, group of individuals, entity, machine, and/or mechanism that interacts with client 70. In some embodiments, user 68 may be a customer user 68 a or consultant user 68 b. Customer user 68 a may comprise any user 68 associated with one or more customers 30 in system 10. Customer user 68 a may be an executive, manager, accountant, engineer, technician, contractor, agent, employee, and/or any suitable representative of customer 30. Client 70 and/or manager server 44 may customize GUI 72 of client 70 associated with a particular customer user 68 a based at least in part on the role (e.g., executive, manager, engineer, etc.) of the particular customer user 68 a. For example, GUI 72 for accountant employed by customer 30 may display itemized cost data for each invoice 16 while GUI 72 for technician employed by customer 30 may display site data 36 comprising the efficiency of customer systems 28 at site 24. Thus, client 70 and/or manager server 44 may generate GUIs 72 that are tailored to the particular functions and/or responsibilities of the particular customer user 68 a. In some embodiments, user 68 is a consultant user 68 b. Consultant user 68 b may by an operator, agent, employee, and/or any suitable representative of a consulting company that provides consulting services to customer 30. In some embodiments, customer 30 may hire the consulting company to provide services directed to reducing utility costs 12 of customer 30. According to certain embodiments, the consulting company may own, operate, and/or maintain platform 40. In some embodiments, customer 30 may pay fees to the consulting company in exchange for receiving access to platform 40 and/or other services of consultant user 68 b. Vendors 20, sites 24, platform 40, market center 50, weather center 60, and/or clients 70 may be communicatively coupled via one or more networks 80.

In some embodiments, strategies 18 may comprise correcting errors identified by platform 40 such as, for example, billing errors and/or metering errors. According to certain embodiments, strategies 18 may comprise opportunities to reduce future utility costs 12. For example, strategies 18 may comprise renewing and/or renegotiating supply contract 22 with a particular type of rate, applying for credits from vendors 20, and/or changing one or more operating parameters of site 24. Platform 40 may cause client 70 to generate one or more GUIs 72 that display the determined strategies 18 to user 68.
FIG. 2 illustrates the distribution of utility resources 14 from vendors 20 to customers 30, according to certain embodiments. The distribution of utility resources 14 in system 10 may comprise utility lines 32, meters 74, service points 76, and submeters 78. As explained above, vendor 20 may provide utility resources 14 to sites 24 via one or more utility lines 32. Utility line 32 may comprise any suitable equipment for providing utility resource 14 to customer 30. For example, utility line 32 may comprise one or more cables, wires, conductors, buses, channels, pipes, canals, conduits, ducts, and/or any suitable type and/or combination of equipment. In some embodiments, utility line 32 may be owned, operated, and/or maintained by vendor 20 and/or another business entity (e.g., �wires� company, distribution company, etc.).
Each site 24 in system 10 may comprise one or more meters 74. Meter 74 may measure the amount of utility resource 14 provided to site 24. Measuring the amount of utility resource 14 provided to site 24 may comprise measuring the volume, flow rate, mass, weight, energy, and/or quantity of utility resource 14 provided to site 24. Meter 74 may comprise any suitable measuring device such as, for example, an electromechanical meter, solid state meter, multiple tariff meter, automated meter reading (AMR) meter, time of usage (TOU) meter, interval usage meter, and/or any suitable type of meter. Each site 24 may comprise at least one meter 74 for each type of utility resource 14 delivered to site 24. In some embodiments, site server 34 associated with site 24 may collect and store measurements from meters 74 at site 24. Site server 34 may transmit the measurements from meters 74 to platform 40 as part of site data 36.
In some embodiments, each meter 74 in system 10 may be owned, operated, and/or maintained by vendor 20 and/or another utility company. Each meter 74 may be associated with a respective meter identifier 82. Meter identifier 82 for a particular meter 74 may comprise one or more alphanumeric characters and/or symbols that uniquely identify the particular meter 74. Meter identifier 82 may be printed on, stamped on, etched on, and/or otherwise associated with meter 74. In some embodiments, the manufacturer of meter 74 may determine and assign meter identifier 82 to meter 74.
According to certain embodiments, the physical location of each meter 74 may be referred to as a service point 76. Service point 76 may comprise the point of delivery of utility resource 14 from vendor 20 to customer 30. In some embodiments, service point 76 may represent the point at which ownership of utility resource 14 transfers from vendor 20 to customer 30. Site 24 may have one or more meters 74 for a particular type of utility resource 14. As a result, site 24 may also have one or more service points 76 for the particular type of utility resource 14.
Each service point 76 may be associated with a unique service point identifier 84. Service point identifier 84 for a particular service point 76 may comprise one or more alphanumeric characters and/or symbols that uniquely identify the particular service point 76. In some embodiments, a regulatory agency or other governing body determines and assigns a respective service point identifier 84 to each service point 76 in system 10. Service point identifier 84 for a particular service point 76 may be determined and assigned independently from meter identifier 82 for meter 74 at the particular service point 76. Accordingly, service point identifier 84 may not change if the existing meter 74 at service point 76 is replaced with a new meter 74 having a new meter identifier 82.
In some embodiments, site 24 may comprise one or more submeters 78. Each submeter 78 at site 24 may measure usage of utility resource 14 by a respective customer system 28 at site 24. Accordingly, if site 24 has multiple customer systems 28, each customer system 28 may be associated with a respective submeter 78. For example, site 24 may comprise one submeter 78 that measures electricity usage of a chiller plant at site 24 and another submeter 78 that measures electricity usage of a lighting system at site 24. Submeters 78 may permit customer 30 to monitor usage of utility resource 14 by each customer system 28 with more granularity than permitted by meter 74. Submeter 78 may comprise any suitable measuring device such as, for example, an electromechanical meter, solid state meter, multiple tariff meter, automated meter reading (AMR) meter, time of usage (TOU) meter, interval usage meter, and/or any suitable type of meter. In some embodiments, site server 34 associated with site 24 may collect and store measurements from submeters 78. Site server 34 may transmit the measurements from submeters 78 to platform 40 as part of site data 36.
FIG. 3 illustrates example invoice data 64 stored in memory module 46, according to certain embodiments. As explained above, invoice data 64 may comprise information regarding past and current invoices 16 from vendors 20 to customers 30. In some embodiments, invoice data 64 may comprise utility usages 26 and utility costs 12. Utility usage 26 may represent the amount of utility resource 14 consumed by at least a portion of site 24 during a given billing period (e.g., week, month, quarter, etc.). In some embodiments, utility usage 26 may represent the amount of utility resource 14 delivered by vendor 20 to a particular service point 76 at site 24 during a given billing period. Accordingly, if site 24 comprises more than one service point 76, site 24 may be associated with more than one value of utility usage 26 for a given billing period. Utility usage 26 may be expressed in any suitable units. For example, where utility resource 14 is electricity, utility usage 26 may be expressed as kilowatt hours (kWh), joules (J), and/or any suitable unit. As another example, where utility resource 14 is natural gas, utility usage 26 may be expressed as cubic feet, British Thermal Units (BTUs), and/or any suitable unit. As yet another example, where utility resource 14 is water, utility usage 26 may be expressed as cubic meters, cubic feet, and/or any suitable unit.
In some embodiments, invoice data 64 comprises utility costs 12. Utility cost 12 may represent the monetary amount that vendor 20 charges to customer 30 for utility resource 14 consumed by at least a portion of site 24 during a given billing period. In some embodiments, utility cost 12 represents the monetary amount that vendor 20 charges for utility resource 14 delivered to a particular service point 76 at site 24.
In some embodiments, invoice data 64 may comprise a site address, account identifier 86, vendor name, and meter identifier 82 in association with each value of utility usage 26 and/or utility cost 12. A site address may indicate the street address of site 24 that consumed utility resource 14 associated with utility usage 26 and/or utility cost 12. Account identifier 86 may comprise one or more alphanumeric characters and/or symbols that identify the vendor account under which utility resource 14 is provided to site 24. Meter identifier 82 may identify the particular meter 74 that measured the amount of utility resource 14 delivered to service point 76 at site 24.
In some embodiments, invoice data 64 may be indexed according to service point identifier 84. Thus, platform 40 may store service point identifier 84 in association with each utility usage 26 and utility cost 12 from each invoice 16.
Indexing invoice data 64 according to service point identifier 84 may permit platform 40 to efficiently and accurately respond to queries for invoice data 64. In some embodiments, indexing invoice data 64 according to service point identifier 84 may permit platform 40 to more accurately respond to queries than if invoice data 64 were indexed only according to meter identifier 82. Because meter 74 at site 24 may be occasionally replaced, meter identifier 82 associated with site 24 may change. Where site 24 comprises meter 74 that was recently replaced, a query that is based on meter identifier 82 of the current meter 74 may not retrieve historical invoice data 64 associated with the prior meter 74. In contrast, service point identifier 84 of service point 76 does not change when meter 74 at service point 76 is replaced. Thus, a query that is based on service point identifier 84 may retrieve current and historical invoice data 64 associated with current and prior meter(s) 74 at service point 76. As a result, indexing invoice data 64 in platform 40 according to service point identifier 84 may permit platform 40 to accurately respond to queries for invoice data 64.
An example illustrates certain embodiments. A particular site 24 located at 123 Main Street comprises two service points 76�Service Point A and Service Point B. Meter U at Service Point A was replaced on Nov. 3, 2003. In this example, if user 68 wants to retrieve from platform 40 all historical and current invoice data 64 associated with Service Point A, user 68 may input into client 70 a query that comprises �A� as service point identifier 84. In response to the query, manager server 44 may identify and retrieve from memory module 46 all records associated with �A� as service point identifier 84. Thus, even though a portion of the historical invoice data 64 is associated with a different meter identifier 82 (i.e., Meter Identifier U) than the current invoice data 64 (i.e., Meter Identifier T), manager server 44 may retrieve and provide to user 68 all of the requested invoice data 64.
For similar reasons, indexing invoice data 64 according to service point identifier 84 may permit platform 40 to more accurately respond to queries than if invoice data 64 were indexed only according to account identifier 86. Because customers 30 may occasionally change vendors 20 and/or accounts, account identifiers 86 associated with site 24 may change. Where site 24 is associated with a new account, a query that is based on account identifier 86 of the new account may not yield historical invoice data 64 associated with the prior account. In contrast, service point identifier 84 of a particular service point 76 does not change when account for site 24 changes. Thus, a query that is based on service point identifier 84 may retrieve current and historical invoice data 64 associated with current and prior accounts.
In some embodiments, indexing invoice data 64 according to service point identifier 84 may permit platform 40 to more accurately respond to queries than if invoice data 64 were indexed only according to street addresses of sites 24. As explained above, a particular site 24 may have multiple service points 76. If user 68 wishes to retrieve invoice data 64 for a particular service point 76 at site 24 having multiple service points 76, a query based on the street address of site 24 may yield unwanted invoice data 64 associated with other service points 76 at site 24. For example, with respect to the illustrated invoice data 64, a query comprising a street address of 123 Main Street would yield invoice data 64 for two service points 76�Service Point A and Service Point B. If user 68 wishes to only retrieve invoice data 64 associated with Service Point A, platform 40 may permit user 68 to submit query based on service point identifier 84 rather than street address.
Although the foregoing examples describe invoice data 64 that is indexed according to service point identifier 84, it should be understood that any type of data stored in platform 40 may be indexed according to service point identifier 84. In some embodiments, supply data 62, site data 36, and/or audit data 66 stored in platform 40 may be indexed according to service point identifier 84. For example, audit data 66 may comprise strategies 18 for reducing utility costs 12 of customer 30. Each strategy 18 in audit data 66 may be indexed according to the particular service point identifier 84 for the particular service point 76 to which strategy 18 applies. Thus, any type and/or combination of data stored in platform 40 may be indexed according to service point identifier 84.
FIG. 4 illustrates an example GUI 72 that provides an easy-to-use interactive interface for user 68 of client 70 to search and review supply data 62, site data 36, invoice data 64, and/or audit data 66.

FIG. 11 illustrates an example GUI 72 that displays weather data 42, according to certain embodiments. User 68 may navigate to the illustrated GUI 72 by selecting the weather tab 214. GUI 72 may comprise a site field 424 and one or more weather charts 426. Site field 424 may permit user 68 to select a particular site 24 for which user 68 wishes to normalize utility usage 26.
Weather charts 426 may display information regarding the normalization of utility usage 26 at the selected sites 24. As explained above, platform 40 may use weather data 42 to normalize utility usage 26 at site 24 with respect to weather. Normalizing utility usage 26 for site 24 may comprise increasing or decreasing the actual utility usage 26 at site 24 to account for fluctuations in weather. Utility usage 26 that is normalized with respect to weather may be referred to as normalized usage 428. Normalized usage 428 may indicate to user 68 whether factors other than weather are contributing or have contributed to changes in utility usage 26 at site 24. Such factors may include equipment malfunctions, changes in operating parameters, metering errors, leaks in utility lines 32, and/or other factors that, unlike weather, may be corrected by user 68 to reduce utility costs 12.
Platform 40 may receive weather data 42 from weather center 60. Weather data 42 may include any suitable information regarding the weather at each site 24 of customer 30. Information regarding the weather at site 24 may comprise information regarding the weather near and/or within a configurable distance of site 24 (e.g., at the nearest weather station). In some embodiments, weather data 42 comprises the high temperature, low temperature, average temperature, and/or mean temperature each day. For each site 24, platform 40 may determine a number of degree-days 430 for each day based at least in part on weather data 42. Degree-day 430 may refer to a measurement unit for temperature. In some embodiments, one degree-day 430 may refer to one degree of departure of the daily mean temperature for a given day from a base temperature. For example, if the base temperature is sixty-five degrees Fahrenheit (� F.) and the mean temperature for a given day is eighty-five � F., then the given day may have twenty degree-days 430 (i.e., eighty-five degrees minus sixty-five degrees). In other embodiments, the number of degree-days 430 in a given day may be determined by monitoring the current temperature and continuously integrating the difference between the current temperature and the base temperature.
The base temperature used to calculate degree-days 430 may be any suitable temperature. In some embodiments, base temperature may be an outside temperature at which an average building does not require heating or cooling to maintain the indoor temperature at a configurable comfort level. According to certain embodiments, the base temperature may be from fifty-five to seventy � F. In some embodiments, the base temperature may be sixty-five � F.
In some embodiments, degree-day 430 may be referred to as a cooling degree-day 430 (CDD) or a heating degree-day 430 (HDD). One cooling degree-day 430 may refer to one degree of departure of the daily mean temperature for a given day above a base temperature. One heating degree-day 430 may refer to one degree of departure of the daily mean temperature for a given day below the base temperature. For example, if base temperature is sixty-five � F. and the mean temperature for a given day is thirty-five � F., then the given day has thirty heating degree-days 430. In contrast, if base temperature is sixty-five � F. and the mean temperature for a given day is ninety � F., then the given day has twenty-five cooling degree-days 430.
Platform 40 may determine the number of degree-days 430 for each day of a given year. In some embodiments, platform 40 may then determine the total number of degree-days 430 during one or more periods of time (e.g., week, month, year, etc.). In the illustrated example, each time period comprises thirty days (i.e., each time period roughly corresponds to a respective month). In the example, based at least in part on weather data 42, platform 40 determines that there were forty-two cooling degree-days 430 during February 2004, two hundred fifty-four cooling degree-days 430 during March 2004, and so forth.
To normalize usage data, platform 40 may determine a normalization formula 432 that correlates utility usage 26 and outdoor temperature for a given site 24. In some embodiments, normalization formula 432 may be used to determine the expected utility usage 26 at site 24 as a linear or non-linear function of degree-days 430 at site 24. To determine normalization formula 432, platform 40 may perform a regression based at least in part on historical weather data 42. In the illustrated example, platform 40 performs a linear regression of usage data and weather data 42 over a four-year period (January 2004 to December 2007) to determine normalization formula 432. The regression may be performed according to any suitable method such as, for example, a least-squares method, an errors-in-variables method, a weighted least-squares method, and/or a robust regression method. In this example, platform 40 determines that utility usage 26 at site 24 during a given time period (i.e., thirty days in this example) may be approximated according to the following normalization formula 432:
U=58.391*T+164,199
In the above formula, �U� represents the expected utility usage 26 during a given month and �T� represents the number of degree-days 430 during the given month.
Based at least in part on normalization formula 432, platform 40 may determine a balance point 434 of site 24. Balance point 434 of site 24 refers to the expected utility usage 26 of site 24 during a given month if there were no degree-days 430 during the month. Referring to the above example, if there were no degree-days 430 during the month (i.e., T=0), then the expected utility usage 26 during the month would be 164,199 kWh. Thus, in the above example, balance point 434 of site 24 is 164,199 kWh. In some embodiments, site 24 may comprise one or more customer systems 28 that are operated for purposes other than heating and/or cooling (e.g., assembly line at automobile factory, switch equipment at telephone facility, etc.). These customer systems 28 at may consume utility resources 14 even when there are no degree-days 430. Accordingly, such sites 24 may have balance points 434 that are greater than balance point 434 for site 24 with few or no customer systems 28 operated for purposes other than heating and/or cooling (e.g., warehouse, residence, etc.).
Platform 40 may determine normalized usage 428 of site 24 base at least in part on the expected utility usage 26 during one or more time periods, the actual utility usage 26 during one or more time periods, and/or the determined balance point 434. Platform 40 may determine the expected utility usage 26 for a particular period based at least in part on the determined degree-days 430 for that time period and/or the determined normalization formula 432. In some embodiments, for a given time period, platform 40 may input the determined degree-days 430 into normalization formula 432 to calculate the expected utility usage 26 for that time period. Referring to the illustrated example, platform 40 may determine the expected utility usage 26 during November 2007. In this example, platform 40 determines that there were 290 cooling degree-days 430 in November 2007. Platform 40 inputs this value into the determined normalization formula 432 (in this example, U=58.391*T+164,199) to determine that the expected utility usage 26 for November 2007 is 181,133 kWh. Thus, platform 40 may determine the expected utility usage 26 for each month based at least in part on the number of degree-days 430 during each month and the determined normalization formula 432.
In some embodiments, platform 40 then determines normalized usage 428 for a given time period. In some embodiments, platform 40 determines normalized usage 428 for a given time period based at least in part on the expected utility usage 26 during the time period, the actual utility usage 26 during the time period, and/or the determined balance point 434 of site 24. According to certain embodiments, platform 40 may determine the difference between the expected utility usage 26 for a particular time period and the actual utility usage 26 for the particular time period. Platform 40 may then determine normalized usage 428 by adding or subtracting the determined difference to/from the determined balance point 434 of site 24.
Referring to the previous example, platform 40 is operable to determine normalized usage 428 for November 2007. As explained above, platform 40 may determine that the expected utility usage 26 during November 2007 is 181,133 kWh. Platform 40 may then determine from invoice data 64 that the actual utility usage 26 in November 2007 was 183,842 kWh. Platform 40 may subtract the expected utility usage 26 from the actual utility usage 26 to determine a difference of 2,709 kWh. Platform 40 may then determine normalized usage 428 by adding the determined difference to balance point 434. In this example, platform 40 determines that normalized usage 428 during November 2007 is 166,909 kWh (i.e., 2,709 kWh+164,199 kWh). Thus, 166,909 kWh represents normalized usage 428 of site 24 during November 2007 (e.g., usage if weather were not a contributing factor).
In the foregoing example, platform 40 determines normalized usage 428 of site 24 based at least in part on monthly data (e.g., monthly weather data 42 and monthly usage information). It should be understood, however, that platform 40 may determine normalized usage 428 of site 24 based at least in part on weekly data, bi-weekly data, and/or data for any suitable length of time.
In the foregoing example, platform 40 determines normalized usage 428 of site 24 based at least in part on cooling degree-days 430. It should be understood, however, that platform 40 may determine normalized usage 428 of site 24 based at least in part on heating degree-days 430, cooling degree-days 430, all degree-days 430, and/or any suitable metric for temperature.
In the foregoing example, platform 40 determines normalized usage 428 of electricity at site 24. It should be understood, however, that platform 40 may determine normalized usage 428 of natural gas, water, coal, oil, and/or any suitable utility resource 14.
In the foregoing example, platform 40 determines normalized usage 428 of site 24 based at least in part on a linear regression of historical utility usage 26. It should be understood, however, that platform 40 may determine normalized usage 428 of site 24 based at least in part on a non-linear regression and/or any suitable technique.
FIG. 12 illustrates an example GUI 72 that illustrates the correlation of degree-days 430 with expected utility usage 26 at site 24, according to certain embodiments. GUI 72 may comprise site field 438 and usage graph 440. Site field 438 may permit user 68 to select a particular site 24 for which user 68 wishes to normalize utility usage 26.
Usage graph 440 may display a relationship between historical utility usage 26 and outdoor temperature at the selected site 24. As explained above, platform 40 may determine normalization formula 432 representing a relationship between degree-days 430 and utility usage 26 based at least in part on historical usage data and historical weather data 42 associated with site 24. Platform 40 may use historical usage data and weather data 42 for any suitable period of time. In some embodiments, platform 40 may use historical usage data and weather data 42 for a period longer than or equal to two years. According to certain embodiments, platform 40 may use historical usage and weather data 42 for a period longer than or equal to four years. In the illustrated example, platform 40 uses historical usage and weather data 42 from January 2004 to December 2007 to determine normalization formula 432. For each month during this four-year period, platform 40 determines the average utility usage 26 and the average number of degree-days 430 at site 24. Referring to the example illustrated in FIG. 11, utility usage 26 during the average February from 2004 to 2007 was approximately 169,828 kWh and the number of cooling degree-days 430 during the average February from 2004 to 2007 was fifty-eight. In this example, platform 40 may determine the four-year average utility usage 26 and number of degree-days 430 for each month.
The example usage graph 440 illustrated in FIG. 12 may comprise the determined average utility usage 26 and number of degree-days 430. In some embodiments, usage graph 440 comprises a first axis 442 representing usage of utility resource 14 at site 24 and a second axis 444 representing numbers of degree-days 430 at site 24. For each period (e.g., month) of the year, usage graph 440 may display the long-term (e.g., two-year, four-year, etc.) average for utility usage 26 and number of degree days for each period (illustrated as points 446). In the illustrated example, each point 446 represents the four-year average for utility usage 26 and number of degree days for each month. For example, the first point 446 illustrates utility usage 26 and number of degree days for the average January from 2004 to 2007, the second point 446 illustrates utility usage 26 and number of degree days for the average February from 2004 to 2007, and so forth.
In some embodiments, graph may further comprise a line 448 that represents the relationship between utility usage 26 and number of degree days at site 24. Line 448 may be expressed as normalization formula 432. As explained above, normalization formula 432 may be determined by performing a linear or non-linear regression of historical utility usage 26 and/or weather data 42 for the selected period (e.g., from January 2004 to December 2007).
In some embodiments, usage graph 440 may comprise balance point 434. Balance point 434 may refer to the expected utility usage 26 at site 24 during a period with no degree-days 430. In this example, balance point 434 is illustrated graphically as the y-intercept of line 448 with axis 442 (i.e., 164,199 kWh). As explained above, platform 40 may use the determined formula and balance point 434 to determine normalized usage 428 at site 24.
FIG. 13 illustrates an example GUI 72 that displays normalized usage data, according to certain embodiments. GUI 72 may comprise site field 438 and usage graph 452. Site field 438 may permit user 68 to select a particular site 24 for which user 68 wishes to normalize utility usage 26.
Usage graph 452 may display normalized usage 428 of site 24 for a configurable period of time. Usage graph 452 may comprise a first axis 454 representing normalized usage 428 and a second axis 456 representing one or more periods of time. Usage graph 452 may comprise a first line 458 that indicates the determined balance point 434 of site 24. Graph may comprise a second line 460 that indicates normalized usage 428 at site 24. In the illustrated example, line 460 illustrates normalized usage 428 at site 24 from January 2007 to December 2007. According to certain embodiments, graph may comprise a third line 462 that indicates a long-term average of normalized usage 428 for site 24. In the illustrated example, line 462 represents normalized usage 428 at site 24 based on four-year averages for each month from January 2004 to December 2007.
The graphical presentation of normalized usage 428 may permit user 68 to easily identify problems unrelated to weather that may contribute to changes in usage at site 24. In the illustrated example, user 68 may easily observe that normalized usage 428 for September 2007 in line 460 sharply deviated from both the balance point 434 (i.e., line 458) and the four-year average of normalized usage 428 (i.e., line 462). This observation may alert user 68 to a problem, unrelated to weather, that occurred during September 2007 and that caused an increase in utility usage 26 at site 24. User 68 may then use client 70 to retrieve supply data 62, site data 36, invoice data 64, and/or audit data 66 associated with September 2007 to determine the problem. Without the display of normalized usage 428, user 68 may not as easily detect that the increased utility usage 26 during September 2007 was due to a problem other than weather.
FIG. 14 illustrates an example GUI 72 that displays emission data 56 associated with one or more sites 24, according to certain embodiments. In some embodiments, platform 40 may determine an amount of emissions that are directly and/or indirectly caused by utility usage 26 at site 24. In some embodiments, platform 40 may determine emissions for any suitable pollutant such as, for example, carbon dioxide (CO2), sulfur dioxide (SO2), carbon monoxide (CO), methane, volatile organic compounds, nitric oxide (NO), nitrous oxide (N2O), nitric dioxide (NO2), and/or any suitable pollutants. Platform 40 may determine the amount of emissions attributable to site 24 based at least in part on utility usage 26 at site 24 and at least one emission factor 58. Emission factor 58 may refer to the average emission rate of a given pollutant for a given activity. The activity may be any suitable activity that contributes directly or indirectly to the release of pollutants into the atmosphere. In some embodiments, the activity may be consumption of electricity, usage of steam, usage of chilled water, and/or combustion of gas, oil, diesel, coal, propane, and/or wood. Platform 40 may determine the emission of pollutant based at least in part on the intensity of the particular activity and/or at least one emission factor 58.
In some embodiments, GUI 72 comprises a search field 464 and an emission table 466. Search field 464 may permit user 68 to select at least one type of pollutant for which user 68 wishes to retrieve emission factors 58.
Emission table 466 may display emission factors 58 for the selected pollutant. Each emission factor 58 in emission table 466 may be associated with a respective activity. In the illustrated embodiment, emission table 466 displays emission factors 58 for various activities. For example, emission table 466 display emission factors 58 for usage of electricity (illustrated as column 468); emission factors 58 for combustion of natural gas, oil, diesel, coal, wood, and propane (illustrated as columns 470-480); and emission factors 58 for the consumption of steam and chilled water (illustrated as columns 482-484).
In some embodiments, each emission factor 58 in emission table 466 may be associated with a respective location (illustrated as column 486). In the illustrated example, each emission factor 58 is associated with a respective state. According to certain embodiments, emission factor 58 for a particular activity in one location may be different from emission factor 58 for the same activity in a different location. For example, the CO2 emission factor 58 for usage of electricity in Connecticut may be 754.1860 lbs/MWh while the CO2 emission factor 58 for usage of electricity in Indiana may be 2098.0280 lbs/MWh. In some embodiments, this difference may be due to different locations having different sources of electricity. For example, a higher percentage of Connecticut's electricity may be generated from clean sources (e.g., nuclear, wind, and/or geothermal energy) and/or a higher percentage of Indiana's electricity may be generated from more polluting sources (e.g., coal, oil, and/or gas).
Although the illustrated example shows emission factors 58 for CO2, it should be understood that GUI 72 may display emission factors 58 for any suitable type and/or combination of pollutants.
FIG. 15 illustrates an example GUI 72 that displays emissions that are directly and/or indirectly caused by utility usage 26 at site 24. GUI 72 may comprise site field 488 and emission graph 490. Site field 488 may permit user 68 to select a particular site 24 for displaying emission data 56.
Emission graph 490 may graphically illustrate emissions that are directly or indirectly caused by utility usage 26 at site 24. As explained above, platform 40 may determine the emission of pollutants attributable to site 24 based at least in part on a particular activity at site 24 and/or at least one emission factor 58. In some embodiments, platform 40 determines the emission of pollutants according to the following formula:
P=A*F In the above formula, �P� may represent the amount of pollutant that is emitted into the atmosphere. �P� may be expressed according to any suitable metric such as, for example, weight, mass, and/or volume. �A� may represent the particular activity that causes the emission of pollutants. As explained above, the activity may comprise consuming resources such as, for example, energy and water. �A� may be expressed according to any suitable metric such as, for example, energy or work. �F� may represent the appropriate emission factor 58 based on the particular activity and the location of activity.
An example illustrates certain embodiments. GUI 72 may display to user 68 that site 24 in California used fifty MWh of electricity during a particular period. User 68 may request platform 40 to determine the amount of CO2 emissions that are attributable to the usage of electricity at site 24 during the particular period. In response to the request from user 68, platform 40 may determine the appropriate CO2 emission factor 58 for the usage of electricity in California. In this example, platform 40 determines, based at least in part on emission table, that the appropriate CO2 emission factor 58 is 700.4000 lbs/MWh. In this example, platform 40 determines the amount of CO2 emissions attributable to site 24 by multiplying utility usage 26 at site 24 by the appropriate emission factor 58. Accordingly, platform 40 determines that the amount of CO2 emissions attributable to site 24 during the particular period is approximately 35,020 lbs of CO2.
Although platform 40 determines CO2 emissions for site 24 in the foregoing example, it should be understood that platform 40 may determine emissions of any type and/or combination of pollutants.
FIG. 16 illustrates an example GUI 72 that displays information regarding emissions attributable to site 24. In some embodiments, platform 40 may convert emissions attributable to site 24 to emissions produced or consumed by a commodity.
The commodity may be any suitable object, item, and/or entity that consumes and/or produces (directly and/or indirectly) pollutants. In some embodiments, the commodity may be vehicles and/or homes that produce emissions (either directly or indirectly). In other embodiments, the commodity may be trees and/or plants that consume pollutants such as, for example, CO2. Platform 40 may convert an amount of pollutants attributable to site 24 to an amount of any suitable commodity. For example, platform 40 may convert a particular amount of CO2 emissions to a number of forest acres that, on average, consume the particular amount of CO2 emissions during a given period. As another example, platform 40 may convert a particular amount of CO2 emissions to a number of vehicles that, on average, emit the particular amount of CO2 emissions during a given period. Although the foregoing examples describe trees and vehicles as commodities, platform 40 may convert emissions of pollutants to any type and/or combination of commodities.
In some embodiments, platform 40 may store in manager memory 48 one or more conversion factors 492. Platform 40 may convert emissions attributable to site 24 to emissions produced or consumed by a particular commodity based at least in part on conversion factor 492. In some embodiments, platform 40 may multiply a particular amount of emissions attributable to site 24 by conversion factor 492 to determine an amount of a particular commodity that consumes or produces the particular amount of emissions. Platform 40 may store any suitably type and/or combination of conversion factors 492. In some embodiments, platform 40 may store conversion factors 492 for emissions comprising carbon dioxide (CO2), sulfur dioxide (SO2), carbon monoxide (CO), methane, volatile organic compounds, nitric oxide (NO), nitrous oxide (N2O), nitric dioxide (NO2), and/or any suitable pollutants. In the illustrated example, GUI 72 displays conversion factor 492 of 8.71E-5 for converting a particular amount of CO2 (expressed in lbs) to the number of average vehicles that collectively emit the particular amount of CO2 each year. Although the example GUI 72 displays a particular conversion factor 492 for vehicles, GUI 72 may be operable to display any suitable conversions factors for any type and/or combination of commodities.
In some embodiments, platform 40 may convert a reduction or increase in emissions for site 24 to an amount of at least one commodity. For example, if customer 30 reduces usage of electricity at site 24, platform 40 may determine a reduction in CO2 emissions attributable to site 24 and convert the determined reduction to at least one commodity. As an example, customer 30 reduces emissions at site 24 during a particular year by fifty MWh in comparison to the previous year. Using emission factor 58 and the location of site 24, platform 40 determines that the reduction in electricity usage resulted in a reduction in emissions of 35,020 lbs of CO2, as illustrated in the example emission graph 494. Based at least in part on this reduction in emissions, platform 40 may determine a number of average vehicles that emit an equivalent quantity of CO2 during a given year. In this example, platform 40 determines that conversion factor 492 for converting lbs CO2 per period to number of average vehicles per year is 8.71E-5. In this example, platform 40 multiplies 35,020 lbs by 8.71E-5 to determine that the reduction in electricity usage at site 24 during the particular year is approximately equal to CO2 emissions of approximately three average vehicles during a year, as illustrated in commodity graph 496. Thus, customer 30 may report to investors and/or other interested individuals that its reduction of electricity usage at site 24 during the year was equivalent to removing three average vehicles from the road during a year.
Although the foregoing example describes converting emissions to an equivalent number of vehicles, platform 40 may be operable to convert emissions to an equivalent number of acres of trees saved by the reduction in emissions, to an equivalent number of single-family homes, and/or to an equivalent amount of any suitable commodity.
In some embodiments, platform 40 may determine an increase or reduction in emissions attributable to site 24 based at least in part on normalized usage 428 at site 24. For example, platform 40 may determine the difference between balance point 434 for site 24 and normalized usage 428 at site 24 during a particular time period. Based at least in part on emission factor 58, platform 40 may determine a particular amount of emissions that corresponds to the determined difference between balanced point and normalized usage 428 at site 24. In some embodiments, platform 40 may convert the particular amount of emissions to a particular commodity (e.g., forest acres, vehicles, etc.) that produce and/or consume pollutants.
An example illustrates certain embodiments. In the illustrated example, platform 40 determines that balance point 434 for Green Tower is 150,025 kWh. Platform 40 further determines that normalized usage 428 for Green Tower during January 2007 was 120,025 kWh. Accordingly, due to factors other than weather, Green Tower consumed 30,000 kWh fewer than expected during January 2007.
In this example, platform 40 determines that the appropriate CO2 emission factor 58 for the selected site 24 is 0.7004 lbs/kWh. Accordingly, platform 40 multiplies emission factor 58 by 30,000 kWh to determine that the reduction in normalized usage 428 during January 2007 caused a reduction in emissions of 21,012 lbs CO2. Platform 40 then multiplies the determined reduction in emissions by the appropriate conversion factor 492 to determine that the reduction in normalized usage 428 at site 24 during January 2007 was equivalent to removing two average vehicles from the road during a year.
Thus, GUI 72 may allow user 68 to observe the effect on emissions caused by an increase or decrease in utility usage 26 at site 24. Knowing the environmental effect of utility usage 26 at site 24 may be valuable to interested parties such as, for example, investors, regulators, lawmakers, and/or other individuals and entities. In some embodiments, expressing changes in emissions associated with changes in normalized usage 428 at site 24 may demonstrate how the activities of customer 30, rather than the weather, are affecting emissions.
FIG. 17 illustrates a flowchart for retrieving invoice data 64 that is indexed according to service point identifier 84, according to certain embodiments. The method begins at step 602 where manager processor 52 receives invoice from vendor 20. Invoice 16 may comprise any suitable information such as, for example, utility usage 26 and utility cost 12 for a given billing period. At step 604, manager processor 52 determines service point identifier 84 associated with invoice 16. Service point identifier 84 may uniquely identify the particular service point to which vendor 20 delivered utility resource 14 associated with invoice 16. At step 606, manager processor 52 stores in memory module 46 service point identifier 84 in association with utility usage 26 and/or utility cost 12 from invoice 16. In some embodiments, manager processor 52 may further store in memory module 46 at least one account identifier 86, site name, street address, and/or meter identifier 82 associated with service point identifier 84. Manager processor 52 may repeat steps 604 to 606 for each invoice 16 received from each vendor 20 in system 10.
At step 608, manager processor 52 generates GUI 72 that displays a plurality of service point identifiers 84. In some embodiments, client 70 displays GUI 72 to user 68. User 68 may submit a query by at least selecting one or more of the displayed service point identifiers 84. At step 610, manager processor 52 may receive from client 70 a query comprising at least one service point identifier 84. At step 612, manager processor 52 may identify in memory module 46 one or more values for utility usage 26 and/or utility cost 12 associated with service point identifier 84 from the query. At step 614, manager processor 52 may generate GUI 72 that displays the identified utility usage 26 and/or utility cost 12. Client 70 may display GUI 72 to user 68. The method then ends.
FIG. 18 illustrates a flowchart for determining normalized usage 428 of utility resource 14 at site 24, according to certain embodiments. The method begins at step 702 where manager processor 52 receives a query for normalized usage 428 at site 24 during a first set of time periods. At step 704, manager processor 52 determines utility usage 26 at site 24 during each time period from a second set of time periods. In some embodiments, the first set of time periods and the second set of time periods may be the same or may overlap. For example, the first set of time periods may comprise each month from January 2007 to December 2007 and the second set of time periods may comprise each month from January 2004 to December 2007. In other embodiments, the first set of time periods may not overlap with the second set of time periods.
At step 706, manager processor 52 may determine the number of degree-days 430 at site 24 during each time period from the second set of time periods. Manager processor 52 may determine the number of degree-days 430 based at least in part on weather data 42 from weather center 60. At step 708, manager processor 52 determines normalization formula 432 that expresses an expected utility usage 26 at site 24 during a particular time period as a function of the number of degree-days 430 at site 24 during the particular time period. Normalization formula 432 may be determined based at least in part on a linear or non-linear regression of the determined utility usage 26 and/or determined number of degree-days 430 at site 24 during each time period from the second plurality of time periods.
At step 710, manager processor 52 may determine balance point 434 of site 24 based at least in part on normalization formula 432. Balance point 434 may represent the expected utility usage 26 of site 24 during a particular time period if there were no degree-days 430 during the particular time period. At step 712, manager processor 52 may determine the number of degree-days 430 at site 24 during each time period from the first set of time periods. Manager processor 52 may determine the number of degree-days 430 based at least in part on weather data 42 from weather center 60. At step 714, manager processor 52 may determine the expected utility usage 26 at site 24 during each time period from the first set of time periods. The expected utility usage 26 at site 24 during a particular time period may be based at least in part on normalization formula 432 and the number of degree-days 430 at site 24 during the particular time period.
At step 716, manager processor 52 may determine the difference between the expected utility usage 26 and balance point 434 at site 24 during each time period from the first set of time periods. At step 718, manager processor 52 may determine normalized usage 428 for each time period from the first set of time periods by adding balance point 434 to the determined difference for each time period from the first set of time periods. At step 720, manager processor 52 may generate GUI 72 that comprises graph illustrating normalized usage 428 at site 24 during each time period from the first set of time periods. Deviations of normalized usage 428 from balance point 434 of site 24 may indicate that factors other than weather are causing increases or decreases of utility usage 26 at site 24. The method then ends.
FIG. 19 illustrates a flowchart for generating GUI 72 that displays information regarding emissions of a particular pollutant caused directly or indirectly by changes in normalized usage 428 at site 24. The method begins at step 802 where manager processor 52 receives from client 70 a request to display emission data 56 based on changes in normalized usage 428 at site 24 during a particular time period. At step 804, manager processor 52 determines balance point 434 of site 24. At step 806, manager processor 52 determines normalized usage 428 at site 24 during the particular time period. Manager processor 52 may determine balance point 434 and/or normalized usage 428 according to the method described above with respect to FIG. 18.
At step 808, manager processor 52 determines the difference between balance point 434 of site 24 and the determined normalized usage 428 at site 24 during the particular time period. At step 810, manager processor 52 determines the appropriate emission factor 58 associated with the particular pollutant and the selected site 24. Manager processor 52 may determine emission factor 58 based at least in part on emission data 56 stored in manager memory 48. At step 812, platform 40 determines an amount of emissions based at least in part on the determined emission factor 58 and the determined difference between balance point 434 of site 24 and the determined normalized usage 428 at site 24 during the particular time period.
At step 814, manager processor 52 determines an appropriate conversion factor 492 for converting the determined amount of emissions to an amount of a commodity that consumes or produces emissions. The commodity may be any suitable commodity such as, for example, forest acres, vehicles, and single-family homes. Manager processor 52 may determine the appropriate conversion factor 492 based at least in part on emission data 56 stored in manager memory 48. At step 816, based at least in part on the determined conversion factor 492 and the determined amount of emissions, manager processor 52 may determine an amount of the commodity that consumes or produces the determined amount of emissions during a particular time period. At step 818, manager processor 52 may generate GUI 72 that graphically illustrates the increase or decrease in emissions caused directly or indirectly by a change in normalized usage 428 at site 24. In some embodiments, GUI 72 may graphically illustrate the determined amount of the commodity. Client 70 may display GUI 72 to user 68. The method then ends.
