Property analytics that make sustainability measurable for Danish realtors.
An interactive real-time property analytics platform for a progressive Copenhagen realtor — combining React, Node.js, MySQL, Redis, and Danish government APIs (DAWA and EMOWeb) to deliver building data, energy labels, CO₂ insights, and automated change notifications.
Realtors were stuck with outdated reports and no change alerts.
Danish realtors and investors had no single place for live building data, energy performance, and CO₂ insights — and no way to know when property or energy-label data changed.
Outdated property reports
Static reports drove inaccurate analysis and poor investment decisions.
No change notifications
Property data and energy-label updates went unnoticed until clients asked.
Slow government APIs at scale
Large building-data volumes made live queries too slow for practical use.
Issues without solutions
Problems were flagged to clients with no recommended corrective actions.
