Høje Taastrup Living Lab: Borgerskolen

About the school:

The school was built in 1901 and has since then been continuously expanded and renovated. The school consists of 16 buildings of different ages, grades and maintenance levels. The buildings therefore vary greatly in style and quality.

The ventilation system has also been expanded on an ongoing basis, causing problems in terms of capacity, monitoring and control.

Current indoor climate:

The school's indoor climate is closely monitored through set indoor climate meters in all of the school's classrooms. In general, it is clear that certain premises are heavily burdened by temperature fluctuations and high CO2 levels. The vast majority of rooms have problems at peak times and at extreme temperatures outside. Only a small number of premises work optimally. Many of the problems are due to the gradual expansion of the school, ventilation systems, building style and older windows.

Aim of the living lab:

  • Enhance indoor climate through IoT
  • Lowering return temperature to district heating
  • Saving heating energy in winter
  • Activating flexibility services to district heating.

Expected outcome:

  • High thermal comfort
  • 10% lower energy bill through lower district heating return temperature
  • 20% less energy use for heating

Partners involved:

  • Høje Taastrup Kommune
  • DTU Compute
  • DTU Byg
  • DTU Fotonik
  • Danfoss
