OpenEMS |
Andy McMillan |
Discussions of Open Systems tend to be long on technical concepts but short on concrete value propositions. I think that is partly because the term “Open” usually gets applied to systems in a technical context rather than a business context and partly because it is just easier to talk about “Open” in abstract terms. But, energy managers and facility directors can not take “abstract” to the CFO for funding nor can they take “technical” to the CEO for approval. To get Open Systems project approval from C-level executives requires that we translate Open Systems concepts into concrete value propositions. Defining OpenEMS and clarifying how it applies to particular organizations is a powerful tool for accomplishing that translation.

What is OpenEMS?
OpenEMS (Open Energy Management Systems) is a
philosophy of doing business where energy-related product and service providers
collaborate and interact through standards-based solutions to deliver maximum
value to building owners and operators. In an OpenEMS environment, while
equipment, software and services may come from different providers they
interoperate quietly and efficiently in the background -- allowing building
owner/operators to focus on their core business.
There is typically a broad range of suppliers making up the “energy ecosystem”
for an owner/operator. The owner/operator may work with utilities, mechanical
service providers, alarm monitoring services, bill-pay-audit services,
electrical contractors, sustainability consultants, demand-response aggregators
and other energy-related product and service providers. Whether these providers
are external suppliers or internal service groups, they are all part of the
process of acquiring, using, controlling and managing the use of energy in a
building.
One way to view an energy ecosystem is to think of it as a building
owner/operators supply chain for energy. It includes all of the organizations
that impact the sourcing, utilization and management of energy. Just like in
manufacturing and retail supply chains, there are substantial value creation
opportunities in improving the efficiency of interaction among the stakeholders
in an energy ecosystem. OpenEMS is about accelerating the flow of information
among those stakeholders while reducing the cost of transactions … and these can
dramatically increase efficiency.
Improving the efficiency of interactions through links among business processes
and information systems serving stakeholders in an energy ecosystem yields
maximum owner/operator value. OpenEMS is the most cost-effective way to link
these systems and share required business and technical information among the
broad range players. This will result in substantial gains that flow to all of
the stakeholders and benefit everyone through lower overall costs of doing
business.
Who Benefits from OpenEMS?
OpenEMS offers substantial benefits to building owner/operators in a variety of
operating scenarios. (Check out www.OpenEMS.com
for animated examples of typical scenarios in the retail sector.) OpenEMS can
lower costs, reduce environmental footprints and increase productivity of
facility management staff. Owner/operators achieve lower costs through direct
reductions in energy use, better utilization of service resources and lower
exception processing costs. But owner/operators are not the only ones who
benefit.
Commercial and industrial buildings account for a large fraction of the total
energy used in the US. There is tremendous potential for reducing building
energy use through improved energy efficiency. There is also tremendous
potential for improving the effectiveness of energy utilization in buildings
through automated interaction among building systems, utilities and facility
management systems. OpenEMS enables these interactions and as a result, benefits
not only building owner/operators but also product and service suppliers as well
as society as a whole.

Where Can You Get OpenEMS?
OpenEMS doesn't come in a box, on a truck, or through the mail. It is a web of
business and technical connections among a building owner/operator and their
suppliers. Of course, those connections require a technical foundation, or
information platform, that bridges the gap between building automation (where
BACnet is the key technology) and IT (where Web Services is the key technology).
For a building owner/operator, that foundation will necessarily encompass their
energy management system and that is why energy management system selection is a
critical issue.
Energy management systems, and the companies that support and maintain them,
must be full participants in the energy ecosystems of building owner/operators.
This requires a different kind of system and a different kind of company. It
requires energy management systems that support transparent industry-wide
interconnection. Vendor-specific “standards” will not be sufficient.
Collaboration among supplier companies will be equally important. No one company
can optimally fulfill all roles in an energy ecosystem. As such, selecting an
energy management system with the goal of implementing OpenEMS means selecting a
partner as well as a product.
Conclusion
In a world of volatile rate structures, dynamic regulation and uncertain
economics, energy management systems must do much more than just manage and
optimize energy use. They must be integral components in energy ecosystems where
they create a foundation for OpenEMS. Energy management suppliers must do more,
too. By definition, no single supplier can deliver on the full value of OpenEMS,
so best-in-class suppliers must work together to serve a building owner's
diverse and often complex energy management and information needs. In future
columns I will walk through some specific scenarios where collaborative
suppliers and OpenEMS can deliver concrete value to building owner/operators.
