DK CASE HTK – ELEXIA – Smart Sensors in Høje-Taastrup Town Hall

Høje-Taastrup Municipality has implemented smart sensors at the CityTown Hall as part of the Danish pilot in the ELEXIA project.

The Høje-Taastrup Town Hall - Copenhagen Area, Denmark

The sensors include indoor climate sensors and desk activity sensors that collect data on temperature, humidity, air quality, and workspace usage.

The aim is to send the data to a datalake, which can be accessed by tool developers to enrich their models and develop solutions for the pilot. The goal is to support smarter, more sustainable energy planning and operations.

The sensors make it possible to monitor real-time conditions and integrate user feedback into the building’s energy management. This approach supports a “human-in-the-loop” system where energy use is aligned with how the building is actually used by employees and visitors.

This user involvement is facilitated through FeedMe, an app developed by the project partner Climify. FeedMe is a user experience and engagement system designed to enhance comfort and satisfaction in indoor environments. By collecting real-time feedback from users on factors such as air quality, temperature, and overall comfort. The app not only helps maintain optimal indoor conditions but also promotes a more responsive and personalized environment.

As one of three pilots in the ELEXIA project — along with Bergen (NO) and Sines (PT) — Høje-Taastrup focuses on optimizing energy consumption in existing public buildings using data-driven tools and user engagement.

The initiative is a step towards creating more flexible and responsive energy systems in municipal facilities, based on actual usage patterns and environmental conditions.
