Ecology and economy are two words with the same root. Similarly, the focus on sustainability in business has two sorts of "green" impacts: on the environment and (if you do it right) on the bottom line. Perillon has an on-demand and cloud computing-based solution for companies that want to manage their double-green sustainability efforts more effectively. Perillon Workspace Suite offers "sustainability performance management" for organizations in energy and environmental management. It delivers the kind of benefits that all enterprise performance management systems are designed to provide: the ability to assemble all relevant performance-related data, put that data into the proper context, present it relative to objectives, provide individual managers with alerts when results require their specific attention and incorporate a mechanism for ensuring that out-of-tolerance situations are addressed adequately. Moreover, because of its engineering history, Perillon captures data, in effect, all the way from the smokestack and not just in the technology stack. This differentiates the product from reporting tools that, while intelligent enough to have already built data and reporting structures designed to support sustainability efforts, must obtain the data from separate systems.
