Rec Analyzer: an energy consumption analysis web app for the Netherlands
ScalaCode built Rec Analyzer for a smart energy solutions provider in the Netherlands. The web app collects data from municipalities, business parks and companies, calculates their electricity, gas and heat consumption, and produces reports with energy-saving recommendations.
A smart energy solutions provider in the Netherlands
The client works on energy consumption in the Netherlands. It needed a web application that calculates and analyses electricity, gas and heat use for municipalities, business parks and companies, gives them insights they can act on, and supports the adoption of energy-saving installations.
What the platform had to handle
Large data sets
Data for many entities had to be stored, managed and used for precise consumption calculations.
Four user roles
Admin, Sales, Engineer and Project Manager each needed their own permissions to keep data secure.
Custom reports and quotations
The platform had to calculate energy use, generate customised PDF quotations and support energy-saving measures.
Several languages
Local companies needed the application in more than one language.

A calculation engine with role-based reporting
A Django and React web app that turns entity data into energy calculations and customised reports.
- 01
Role-based access control
Each role sees the data and functions it needs, which keeps information secure.
- 02
Calculation engine
The engine computes electricity, gas and heat consumption metrics for each entity.
- 03
