With a view to improving energy efficiency at Reading station Network Rail have commissioned a project. There are plans to install sensors across the station to monitor real-time data on the station’s energy use. Being able to understand and improve the station’s energy peformance is due to a computer modelling platform which has developed a digital twin of the station to include a simulation of the current energy use.
With the use of existing, historical data and modelling, opportunities have been spotted that could result in approximately a 20% improvement in energy performance.
Consulting engineer Atkins, using Cardiff University’s Cumputational Urban Sustainability Platform (CUSP) are responsible for the creation of the digital twin.
WIth the use of this data and computer modelling baselines have been created showing the stations’s energy consumption and carbon emissions and CUSP has been used to map out ways of improving the station’s performance by energy efficiency measures while also explaining further changes and the potential impact this could have while making additional energy savings.
Ideas for energy saving that this technology has shown so far:-
- turning off escalators and other machinery when not in use or overnight when the station is shut
- automatically dimming lights in areas not in use
Together with the data which will be collected by the sensors at the station passenger and station-user behaviour will also be recorded in order to understand how identified energy savings might impact safety and experiences when in the station.
It is hoped that eventually the Reading station initiative will be rolled out across other stations.
