About Borgerskolen 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.
Progress so far:
The Høje Taastrup Kommune Living Lab is divided into two test areas: Parkskolen and Borgerskolen. Common for both test areas is that the main focus of the year 2020 was to establish a customized setup in the schools and to establish the data transfer to Center Denmark.
The FED-partner Neogrid has started the establishment of a suitable CTS-setup at Parkskolen, and getting the mixing loop in order.
The work regarding the test area at Borgerskolen started in Q4 2020. DTU Compute has set up and tested connections to sensors (temperature, CO2 etc. in classrooms, BEMS with measurements from heating systems etc.) and actuators (thermostats on radiators). After finally getting everything connected and tested, DTU has started experiments at the school. Due to the COVID19 lockdown, DTU has been able to keep the experiments running for a longer time, and the control algorithms based on the data and experience gathered during the experiments have been developed iteratively.
The next milestone for both schools is to get the data transfer to Center Denmark established. Neogrid, DTU Compute and Center Denmark have been working on the establishment in spring 2021.
