Scalable and flexible energy monitoring.

Opinum’s Data Hub solution aims at reducing the energy consumption in both new and old residential and commercial buildings. Thanks to its partnership with Smappee, Opinum is able to offer ESCOs a fully integrated end-to-end solution combining the cutting-edge hardware and the most advanced analytics data management platform. One of Opinum’s clients, Optiwatt, is using the Data Hub solution to monitor and optimise the technical facilities and energy efficiency of buildings for AG Real Estate, Belgium’s largest real estate group, whose portfolio includes office buildings, shopping centers, warehouses and residential buildings.


Affordable, scalable and future-proof.

"Reducing the energy consumption of the real estate stock by 30%, even for old buildings is perfectly possible without major investment," says Nicolas Storms, executive director of Optiwatt. Opinum’s Data Hub solution uses the Smappee hardware components to monitor the energy consumption and production. The compact components can be installed inside the distribution panel without having to make any changes to the electrical installation. The plug-and-play hardware is easy to install and requires no maintenance afterwards thanks to over-the-air updates. The modularity of the Smappee Infinity setup also allows clients to expand the system as their energy needs change over time.
All of these Smappee features make Opinum's Data Hub solution an affordable system that does not require a large investment to install and that can be expanded without major additional costs.

Compatible with 3rd party systems.
“For several years, we have been focusing on providing a robust and flexible energy monitoring solution. Too often, these types of solution are constrained, inflexible and specific to a type of supplier or hardware. The result, sooner or later, is a dead end”, says Loïc Bar, CEO of Opinum. “Therefore, we have made sure that our Data Hub solution only works with components that can integrate with pre-existing energy monitoring environments e.g. sensors, monitoring systems and data processing software. Smappee, for example, has an open API that easily and securely transfers the energy data via the cloud to any 3rd party HEMS or BEMS.”

"Data Hub does not in any way make the client or the provider captive to its solution. This fits perfectly with our requirements and our philosophy of maintaining total scalability, robustness and the ability to share data with our clients”, Nicolas Storms continues. “It’s a win-win situation: we benefit from the richness and efficiency of their solution, and we provide them with our expertise in energy monitoring."

Nicolas Storms (Optiwatt): "We have the freedom to decide not only on the type of sensors and Smappee-hardware, but also on how the data is returned. The solution is very flexible and future-proof as we can pick and choose the features and services we need. Should we need more control, data and services over time, we can easily build on the existing solution to meet our changing needs. "

The building’s energy data in all its aspects.
The Opinum Data Hub solution collects Smappee’s real-time and historical energy consumption and production data. It also retrieves information concerning fuel consumption, meteorological or technical data from distribution system operators or control systems. "Data Hub is suitable for a multitude of uses. Soon we may be adding data from CO2 probes and other sensors”, says Nicolas Storms. “One of Data Hub’s main strengths is its ability to compile all of this data, regardless of format or frequency, making it comparable and interpretable. We can switch between a predetermined set of variables. This enables the system to analyse the energy behaviour of a building and immediately come up with specific indicators, such as the number of kilowatts per hour by m2, the overconsumption percentage, deviations, weekly standard usage and theoretical weekend usage. Based on Smappee’s historical energy data and our analysis, we know how a building is supposed to behave in a given situation and can therefore compare theoretical consumption to actual consumption. For example, we can apply a filter to the main values on Monday morning and visualize possible deviations instantly. Or create a one-year time series, visualize consumption on all the buildings we manage, or compare them according to their size."

“Efficiency gains are significant, Nicolas Storms continues. "The analysis is instant. This saves time both for us and our end customer. In addition to optimizing consumption, this also enables the life of the equipment to be extended, avoiding unnecessary use or predicting the need for maintenance.”

Detailed, actionable energy insights.
Toon Beerens, Property & Sustainability Manager at AG Real Estate, needs to ensure the company’s positive contribution to the community and the planet. “The consumption of our buildings is one of the major factors in that mission. Optiwatt can easily share the building’s data via reports that can be tailored to our requirements. Based on that data, we can implement proactive management, detect anomalies rapidly and respond quickly.”

The continuous energy monitoring and data interpretation has a specific purpose for AG Real Estate: targeting minimum consumption thresholds. "As soon as a limit is exceeded, we are notified”, Toon Beerens adds. “We can closely monitor the overall consumption of the park, both per building and per type of space (whether shared or private) and subdivided per floor. The detail, if we want, can go down to every individual screen, plug or light.”

Data that saves energy, costs and the environment.
Toon Beerens: "Energy compatibility allows us to track the energy footprint of our real estate portfolio over time and reduce it in terms of consumption and CO2 emissions. This is not just about small savings or trivial warnings. One Monday morning, I received an overconsumption report for one of our buildings. The building had apparently used 3,000 liters of water a day. Our maintenance team was sent immediately to discover the cause. Such warnings inform us of any unusual usage for all the different utilities involved, such as gas or electricity."

Every AG Real Estate client has access to their usage profile for the area they occupy. During the course of 2019, buildings managed by AG Real Estate will gradually be equipped with a large screen at reception or at the entrance, allowing anyone entering the building to visualize the results of energy optimization efforts. As a result of these savings, the real estate group is reinvesting in active measures, including the renovation of facilities and solar panel fitting.
