n  2010 MIT Sloan / IBM report on Analytics ¨  Embedding business insight into day-to-day

operations is critical to success

¨  Single greatest opportunity and challenge for the data-driven enterprise

n  2010 survey of 600+ CIOs & IT Managers ¨  Paucity of sustainability information (i.e energy)

¨  Lost opportunity to leverage information to improve sustainability

¨  Significant challenges ahead

n  What is Energy Intelligence? ¨ Transforms raw data into meaningful energy

information

¨ Enables effective strategic, tactical, and operational decision-making for energy mgmt.

¨ Provides energy consumption of business activities so they can be understood and optimized

Energy Intelligence



Energy Intelligence platforms within an Enterprise will

need to support four key requirements

Enterprise Energy Management

n  Help users to: ¨ Understand energy data

¨ Make appropriate energy saving decisions

¨ Support energy performance objectives and other business performance objectives

–  human resources (i.e. occupancy comfort)

–  enterprise resource planning (i.e. room utilization).

Energy Situational Awareness



n  Architecture for Energy Intelligence Platforms ¨ Dataspace for Information Management

¨ Linked Data for sharing Information

¨ Complex Event Processing for Interpreting Data

Proposed Approach



n  Emerging data management architecture n  Recognizes expense obtaining upfront

unifying schema across all sources ¨ Co-existence of data without unifying schema

¨ Loosely integrated set of data sources

n  Data integrated on “as needed” basis ¨ Tighter integration achieved in an incremental

"pay-as-you-go" fashion

Linked Data Principles

1.  Use URIs to identify the “things” in your data

2.  Use HTTP URIs so people (and machines) can look them up on the Web

3.  When a URI is looked up, return a description of the thing in a structured format (RDF)

4.  Include links to related things to provide context

n  Energy Intelligence platforms have 4 key requirements: ¨  Holistic energy consumption

¨  Multi-level energy analysis

¨  Business context energy consumption

¨  Energy situational awareness

n  Linked dataspace for Energy Intelligence (LEI) ¨  Supports requirements using Dataspaces, Linked Data,

Complex Event Processing for Situational Awareness

n  Future work ¨  Investigate appropriate support services for linked dataspaces

using approximation techniques

¨  Interoperability of system services as RESTful services.
