Energy Accounting and Control Platform

Our client came with the challenge 

For over a decade, our client had been offering an integrated web-based platform for observing, analyzing, and regulating the energy consumption of buildings and real estate. Their platform had been helping corporations, hospitals, universities, and many other use energy sustainably. However, one of their end customers started experiencing problems. Due to the growing volume of energy usage data, the performance of the platform’s frontend had started deteriorating, and the lack of data visualization and reporting capabilities became a more acute problem.

This is when our client came to Intellias. They needed to build an experienced web development team that could help their in-house Java backend team in reworking the technological foundation of their legacy Adobe Flex-based frontend application. 

Intellias developed the solution 

Intellias started supplying team members to work as part of our client’s organization. This team was intended to build the frontend for the energy management application using Ext JS and additional APIs and frameworks. 

Over the course of several months, our team evaluated the existing system, analyzed our client’s new requirements, and suggested a totally different frontend architecture both conceptually and technologically. 

This new architecture relied on HTML5 and hundreds of modern JavaScript components to enhance visualization and reporting capabilities. The new solution also outperformed the existing on all popular web browsers when fed twice the volume of usage data. Once the new design was approved, our Intellias team moved on to the development and quality control.

We achieved great results together 

The released product has been highly appreciated by end customers for being faster, more modern looking, more functional, and easier to use. 

Today, our collaboration is still flourishing. Intellias has taken over responsibility for continuous maintenance and further product development. Because of our strong technical expertise, many responsibilities have been transferred to our Intellias team. Collaboration has helped our client to extend their team’s abilities and focus on backend enhancements. Our long-term partnership is built on reliability and a continuous drive for improvement. 

We helped our client’s end users: 

  • Work with a modern and attractive frontend 
  • Load consumption data quickly when browsing data-intensive pages 
  • Analyze energy usage statistics via interactive charts 
  • Generate reports via sophisticated data grids with extended sorting, grouping, and pagination capabilities 

They had a huge impact. The collaboration provided a lot of backend-focused capacities which we can utilize differently. A lot of tasks were transferred to Intellias, which was done well in a reliable way.
