...unnecessary weekend electricity and gas usage alone equated to £12,740...


Findings


The immediate challenge for CCC was to understand their current energy costs and to then implement a strategy to bring about reductions.


The task was made difficult by the historic reliance on a manual procedure that was not only slow and time consuming but inaccurate and out of date. Using the Optimal system CCC was able to collect timely, reliable and accurate data immediately, review it over the web and make informed decisions and implement immediate management changes i.e. when to switch on/off plant, lighting and power sources.


Investigation revealed plant was active when not required, electricity, gas and water was being used over weekends / bank holidays and the building’s base load was unnecessarily high. All this resulted in increased costs and carbon emissions. The extent of the unnecessary weekend electricity and gas usage alone equated to 127 MWh, £12,740 per annum. Combined with further savings through

plant optimisation and creating staff awareness with the dashboard displays these are key contributors to cost savings and carbon reductions.


...energy awareness contributed to a 26% reduction in electricity usage...


Electrical Usage


Through occupier awareness significant electricity saving have been achieved through initiatives between the building occupants, MITIE (facilities management company) and Climate Change Capital (landlord). This has resulted in an


electricity saving, year on year, of 26%. A combination of activities have contributed to this success including; energy awareness campaigns, published usage data in a non technical format through reception dashboards for occupants, improving the BMS controls and setting target reductions.


Solution


Using the Optimal Monitoring system and with reference to historic energy data, building usage profiles were established, differentiating between weekdays and weekends and then real-time ½ hourly usage measured against these profiles. The automated reports this generates are sent out to the building management team keeping them up to date and notified of any excessive usage as it happens, allowing immediate corrective measures to be taken.


Building occupants are fed real time usage data via the dashboard displays, keeping them informed and involved in the carbon reduction program and encouraging participation through this initiative and, thus, behavioural change.


“Right information, Right time,


Right people” Conclusion


In a nutshell, saving energy and utility costs and carbon is simple. It’s all about

getting the right information at the right time to the right people i.e. building managers and building occupants. Once they can see what is going on they can take corrective action to drive out and eliminate waste, cut energy cost and reduce carbon emissions. Testament to the success at Birmingham and the terrific collaboration between landlord and tenants, Tim


Mockett added “We have since put monitors in other buildings in Manchester and London but Birmingham was the pioneer; it has been our flagship investment.”
