2. Related Art
Executing energy evaluations and modeling energy consumption is challenging. Evaluations and models are often based on limited and unverified information. In manufacturing the challenge is greater because industrial attributes are less uniform than residential and commercial attributes and industrial data is not readily available.

An industrial analytic system provides multi-layer industrial energy information at the manufacturing plant level, industrial subsector level, zone level (e.g., zip code level), regional level (e.g., county level), authority level, state level, and national level. The system executes statistical analysis on uniform and disparate datasets accessed from local and remote databases to estimate and forecast manufacturing energy consumption across geographic areas (e.g., such as more than 300,000 manufacturers across the U.S.). The system provides geospatial interlinking to virtual globes and superimposes images and objects on satellite imagery, aerial photography, three dimensional geographic information system globes, and two dimensional maps. Some industrial analytic systems render energy consumption estimates and fuel stream estimates at a granular level. Some industrial analytic systems generate models that provide energy intensive processes per Standard Industrial Classification (SIC) codes, load curves per process step per SIC code, and load factor per type of manufacturing plant, for example. And, some industrial analytic systems include architectures that provide an optimized experience to a variety of mobile devices by rendering content to the form factor of the displays of the mobile devices.
The industrial analytic system includes a database engine that provides access to pluralities of database management systems (DBMS). The database engine pulls information and datasets that may be in a variety of formats from one or more databases, one or more Very Large Databases (VLDB), or data warehouses, some which may contain volumes of data in the hundreds of gigabytes or terabytes size. The database engine may operate across a variety of different local or remote platforms and operating systems and is configured to operate with many different data repository applications including information accessible through Internet Web portals. Some database engines may execute data fusion by mining and integrating raw data from a plurality of sources to produce a new raw data set, such as a fused data set that includes energy consumption and sales, location data, and associated business classification codes.

The standard deviation filter 104 processes the filtered data streams by applying (+/−) n σ of sales and electrical energy consumption, where n σ comprises the number of standard deviations as expressed by equations 1-3.

In some industrial analytic systems, a computation module 110 may execute linear regressions between sales and electrical energy consumption of different manufacturing industries, including industries represented by a 4-digit SIC code. The computational module 110 analyzed correlations between electrical energy consumption and square footage, number of employees per industrial consumer, number of operating hours, etc. The linear relationship may be expressed by equation 4.
y=β0+β1x+ε Equation (4)
Where, β1 represents the slope of the regression line (MWH/Sales), β0 is the intercept and ε the error associated with the empirical observations. In many cases, the error between the data and linear relationship is minimized through the sum of the squared residuals or least squares. The regression coefficients may be solved using equations 5 and 6:
β1=(Σxy−(ΣxEy/n1))/(Σx2−(Σx)2/n1) Equation (5)
β0=(Σy/n1−β1Σx/n1) Equation (6)
Where n1 represents number of data points. In some cases, outliers may cause the regression coefficients (β1 and β0) to have misleading values. The coefficient of determination R2 provides a measure of how well future outcomes are likely to be predicted by the model. In the industrial analytic system, R2 values may range between 0 and 1, where 1 indicates the highest prediction capability. The R2 value may be expressed by equation 7.
R2=1−(Σ(yi−fl)2)/(Σ(yi−y)2) Equation (7)
Where, fl represents the linear regression solution. The available information including sales and electrical energy consumption may be obtained mainly from the IAC DB. This information is applied to the linear regression equation to derive the coefficients of regressions as shown in equation 8.
E(SIC)=βS(SIC)+S0(SIC) Equation (8)
where, E represents electrical energy of a given industry type in MWh, S represents product sales in a given industry type in dollars, and S0 represents a constant determined by the regression analysis. In some industrial analytic systems higher resulting values of β indicate industries where electricity is important in the manufacturing of a given industrial product.
An example of the linear regression performed for the glass industry (SIC 3211) is shown in
A user may access some industrial analytic systems through icons, menus, and dialog boxes rendered by a layout or rendering engine (also referred to as a visualization engine) on a fixed local/remote or mobile screen. The user may select and activate these options through a relative or absolute pointing device, voice commands, gesture controls, and/or eye tracking technology. In

In use, the industrial analytic systems provides multi-layer industrial energy information including industrial energy information across major industry groups (e.g., a first layer at a two digit SIC code) and industrial energy information by specific industries (e.g., a second layer at a four digit SIC code).
Layer 1 of the analysis performed by the industrial analytic systems provides information on the major industry sectors where the combined effect of electricity and product sales is significant. Layer 2 of the analysis performed by the industrial analytic systems returns information on specific type of industries within these sectors including analysis at the process level within each of these industries.
In a second use, the industrial analytic systems modeled industrial electrical energy consumptions at the state level and were compared to those published by DOE's EIA-MECS. As shown in

The industrial analytic systems may utilize available information in publicly available datasets via publicly accessible distributed networks like the Internet or Wide Area Networks to provide estimate of manufacturing electrical energy consumption at multiple levels of details and may require minimal user input. Access to the systems analytics and models may require a user to enter as little as a zip code or an SIC code of desired industrial plant. But the automated data output is vast and may include information such as electric energy intensity (MWH/$) per industry type and per zip code at the state and nationwide levels. Alternative versions of the system includes manufacturing processes steps, energy intensive processes, applicable energy efficiency technologies, and may combine heat and power, to provide detailed analysis on indices of interest such as CHP capabilities across manufacturing sector, available low grade waste heat per industry type and per Region. All of the output may be rendered at a geo-spatial resolution.
The methods, devices, systems, and logic described above may be implemented in or may be interfaced in many other ways in many different combinations of hardware, software or both hardware and software and may be used to process industrial data and visually display objects and content through a visualization engine. For example some alternative industrial analytic system's computational modules 110 and geospatial modules 112 interface a separate mobile computer server or server cluster (also referred to as the mobile architecture) that optimizes the renderings of the content delivered by the layout engine and rendering engine to a variety of mobile devices by fitting the content to the form factor of the device. The mobile architecture receives and the content such as the HTML, scripts, etc., and transforms it to the size and orientation of the requesting mobile device client. The mobile computer server considers what is and what is not supported by the requesting mobile device client such as the script or version of script, flash, etc. that may or not be supported and then changes the objects, information, software, etc. and sends the changed content and software that may be consumed by the mobile device client. The more advanced the mobile device, the more features the mobile computer server will serve to the mobile device client. The mobile computer server translates the content in a variety of different ways as dictated by the disparate operating systems and/or data/software requirements of the mobile device client.
All or parts of the system described above may be executed through one or more controllers, one or more microprocessors (CPUs), one or more signal processors (SPU), one or more graphics processors (GPUs), one or more application specific integrated circuit (ASIC), one or more programmable media or any and all combinations of such hardware. All or part of the logic and modules described above may be implemented as instructions stored on a non-transitory medium executed by a CPU/SPU/GPU that comprises electronics including input/output interfaces, and an up-dateable memory comprising at least a random access memory which is capable of being updated via an electronic medium and which is capable of storing updated information, processors (e.g., CPUs, SPUs, and/or GPUs), controller, an integrated circuit that includes a microcontroller on a single chip or other processing devices and may be displayed through a display driver in communication with a remote or local display, or stored and accessible from a tangible or non-transitory machine-readable or computer-readable medium such as flash memory, random access memory (RAM) or read only memory (ROM), erasable programmable read only memory (EPROM) or other machine-readable medium such as a compact disc read only memory (CDROM), or magnetic or optical disk. Thus, a product, such as a computer program product, includes a specifically programmed non-transitory storage medium and computer readable instructions stored on that medium, which when executed, cause the device to perform the specially programmed operations according to the descriptions above. An engine is one or more specially programmed processors or application programs stored on a non-transitory medium that manages and manipulates data. And a cluster is a group of independent network computers servers that operate—and appear to clients—as if they were a single unit.
The industrial analytic systems may evaluate industrial content shared and/or distributed among multiple users and system components, such as among multiple processors and memories (e.g., non-transient media), including multiple distributed processing systems. Parameters, databases, software, filters and data structures used to evaluate and analyze or pre-process the messages may be separately stored and executed by the processors. It may be incorporated into a single memory block or database, may be logically and/or physically organized in many different ways, and may be implemented in many ways. The programming executed by the industrial analytic systems may be parts (e.g., subroutines) of a single program, separate programs, application program or programs distributed across several memories and processor cores and/or processing nodes, or implemented in many different ways, such as in a library or a shared library accessed through a client server architecture across a private network or publicly accessible network like the Internet. The library may store industrial classification model software code that performs alternative modeling and classifications described herein. While various embodiments have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible.
The term “coupled” disclosed in this description may encompass both direct and indirect coupling. Thus, first and second parts are said to be coupled together when they directly contact one another, as well as when the first part couples to an intermediate part which couples either directly or via one or more additional intermediate parts to the second part. The term “substantially” or “about” may encompass a range that is largely, but not necessarily wholly, that which is specified. It encompasses all but a significant amount. When devices are responsive to commands events, and/or requests, the actions and/or steps of the devices, such as the operations that devices are performing, necessarily occur as a direct or indirect result of the preceding commands, events, actions, and/or requests. In other words, the operations occur as a result of the preceding operations. A device that is responsive to another requires more than an action (i.e., the device's response to) merely follow another action.
While various embodiments of the invention have been described, it will be apparent to those of ordinary skill in the art that many more embodiments and implementations are possible within the scope of the invention. Accordingly, the invention is not to be restricted except in light of the attached claims and their equivalents.
The invention was made with United States government support under Contract No. DE-AC05-00OR22725 awarded by the United States Department of Energy. The United States government has certain rights in the invention.
