Project: Energy Metering
Recognising the impact that rising energy prices would have on them, a College embarked on an ambitious energy saving mission - to cut the College’s annual energy utilities bill from £100,000 to zero. They were looking for a solution to measure and monitor their real time energy consumption and analyse historical utilities data.
The aim of the project was to gradually reduce the College’s annual energy bill from £100,000 to zero through measuring and auditing energy use, investment in renewable energy systems, and behavioural change. Using meters to measure the mains inputs into the school and a Pulse Meter to measure the Solar PV generation, the College could then track both consumption and generation. The data collected from the meters went straight into energy management software, where the facilities team, and students, could view real-time dashboards of energy usage, along with costs and CO2 emissions. The meters also measured the electricity being sent back to the main grid. The College currently runs off of the solar energy it generates. So at times when the demand is lower than the generation, the difference is pushed back to the grid.
Combining meters and software, the college has created an energy dashboard showing the energy being created, the energy being used and the cost per hour.
The savings made from reducing the annual energy spend have funded additional teaching staff for the school, ensuring class sizes stay small and pupils can get the attention they need.
It is the ability to easily see and measure real time energy that underpinned the college’s sustainability and environmental commitment. The College have also used this as a way to involve students - raising awareness and encouraging behavioural change has played a huge part in achieving the reductions. Students get involved in the project throughout their curriculum and also as part of an after school Energy Detectives Club; where pupils use equipment to measure and monitor the energy being used, check if it is within acceptable limits and hunt down where energy waste is happening.
In the future, the college is planning to expand the system and look at the use of gas and water meters as well as starting to measure the energy use in individual rooms and areas within the college. They also aim to install wind turbines to further supplement the school’s electrical supply.
