EnergyData is a modular web application designed to visualize buildings and their utility network usages. It features a map view with building geometry, colored by building age, and reveals detailed information about the utility usage history of each building.

The application is modularized into two parts: EnergyData-API, which is a data abstraction layer for the PostGIS database, and EnergyData-Web, which visualizes the data in a web interface. The OpenLayers library is used to provide an interactive map view with building data on top of a street map.

## Technology Stack

-   PostgreSQL Database with 3D City Database schema for building geometry & measurement data
-   PostGIS for geospatial data management & building geometry optimization
-   Java for server-side components
-   JavaScript and HTML/CSS with Bootstrap for client-side components
-   OpenLayers library for interactive map view
