The University based in London SAVES 25% with Elcomponent Sub-metering
The University is a major seat of learning with over 25000 students and 2,500 full-time members of staff. It comprises four main campus locations.
With over 170 buildings from listed structures to the brand-new at the campus, energy and carbon management is a major challenge, but the university continues to score highly for green credentials. The university implemented its Carbon Management Plan in 2008, and is on target to reduce emissions by 35% via a combination of focused investment and excellent management.
Fundamental to the strategy is the implementation of a comprehensive automatic sub-metering system across all three utilities. This provides half-hour data on both tariff and sub-meters, and can be configured to drive realtime Building Energy Dashboard Displays.
This was demonstrated very clearly when a major lighting and air handling upgrade was carried out at one of the university's buildings. Initial performance was good, but a careful evaluation of the sub-meter data showed that some adjustments were needed, which once implemented resulted in a 25% drop in electricity usage. This equated to approximately 320,000 kWh over a year, or around 168 tons of CO2.
According to the Energy Manager...
"It's essential for a number of reasons that the detailed consumption data which the system provides is readily available in a clear and concise form. One of those reasons is that it is crucial for the evaluation of new energy efficient plant and equipment - of which there is much - to ensure the projected savings are being achieved."
