Building Dynamics-Ameresco's Big Energy Data Solution: Advanced Energy Management System

CIO VendorAndreas Savvides, Ph.D., VP of Technology & Software
In today’s digital age, it’s surprising to find that energy data across a large number of buildings is generally not available in a consistent format; one that can easily be communicated across the different tiers of an organization. In many cases, energy data integration is a significant challenge, particularly for those organizations managing a multitude of buildings with data from different utilities, various meters, and across multiple accounts. Without some form of automation, it is a monumental task for a manager to compile data in a comprehensive format.

Ameresco’s Building Dynamics is a big data software solution that specializes in collecting customer energy data from a wide variety of sources, such as accounting systems, utility systems, meters, and sensors. With its technology-enabled analytics capability, it provides visibility into the customer’s energy usage trends, and uncovers critical insights for making informed energy choices. “Many of our customers have lots of buildings, and they typically don’t have a solution in place for understanding the overall picture and using it to drive their strategic energy and sustainability goals,” points out Andreas Savvides, Ph.D., Vice President of Technology and Software and General Manager of the Building Dynamics team at Ameresco.

The Building Dynamics energy analytics offering is structured in two tiers. The first, called Monitoring and Reporting, is where data is collected from the entire building portfolio, analyzed and presented to the customer in an easy-to-understand form on a web portal or as a report. This helps the customer to understand the state of their portfolio, and allows them to identify opportunities to optimize their energy usage and costs.

The second tier addresses Building Automation Systems (BAS) inside buildings. It continuously reads thousands of data points of information from the BAS and analyzes them to find faults.

We compile and analyze customer data, help the customer understand it, and incorporate their energy strategy, and ultimately manage their day-to-day consumption more effectively


It helps to identify any part of the system that is broken or misconfigured, and finds opportunities for upgrades. In many instances, there are low-cost or no-cost measures that can save the customer a lot of money, such as replacing all lighting with LEDs.

In product manufacturing, for a example, energy is a primary cost. To be price competitive, industrial customers need to understand the breakdown of energy consumed between the different machines in their facility, how much is spent by department and what their options are to become more efficient. Building Dynamics addresses these, and can provide usage information for each product the customer manufactures. In addition, Building Dynamics supports creating a comprehensive energy strategy.

In addition to its capabilities, what sets Building Dynamics apart from other big data providers is that it is integrated within the larger framework of Ameresco, a leading comprehensive energy efficiency and renewable energy company throughout North America and the United Kingdom. This provides access to engineering professionals, who can help customers develop not only their energy data solution but also provide end-to-end project support for innovative, energy efficient solutions. Most importantly, customer service is central to Ameresco. “I personally meet with customers to learn about their goals and pain points,” says Savvides.“We partner with our customers. Their inputs and needs influence the design of the product.”

Savvides believes the connected energy systems is the future. The information provided through, Building Dynamics creates high value for smart cities, healthcare, and universities, and customers with large portfolios of buildings.
