MONITORING/METERING
CASE STUDY – O
nline real-time energy monitoring solution is the driver behind engaging buildings contractors and staff in identifying
opportunities to make energy, carbon and costs savings.
Evergrowing legislations such as the Carbon Reduction Commitment (CRC) tax and EU Emissions Trading Scheme along with financial impact on utilities it is inevitable and presents an opportunity for organisations like the NHS to reduce their buildings energy consumption.
Addressing the basics As part of the Trust’s Carbon
Management Plan which is an integral part of Sustainability Management Plan, it is understood that it is fundamental to know the buildings energy consumption by type, by seasonal patterns, the high/low demand periods to engage buildings maintenance contractors by bringing the energy consumption of the buildings into a clear and instant visibility.
The Sustainability team invested and installed ecoDriver online Real-time energy monitoring solution to monitor energy consumption LIVE by meter type “at any time and from anywhere” of their Queen’s Hospital and King George’s Hospital buildings.
actions were taken to avoid wastage. The live data and its reporting tool helped the team to identify more opportunities, plan in advance for weekends, Bank Holidays, X-Mas and New Year switch-offs. Such actions resulted in immediate savings. So far the Trust, with low/no cost initiatives saved approx. £142k in the past two years.
Getting out more Realising the immediate positive
engagement with the buildings maintenance contractors and staff, the Trust expanded this real-time monitoring system with alert notifications to other meters for example CHP, LV switchboards, boilers and individual departments.
The team has taken a progressive approach in its expansion by engaging occupants and taking financial, energy, carbon savings factors into account. The charts below show the difference in consumption patterns before and after taking actions at their largest site, Queen’s Hospital in Romford.
Finding more solutions for less
The Trust’s Sustainability team view is in the present financial climate it is difficult to fund a complete monitoring & targeting solution using multiple sub meters, especially for PFI managed sites. Our approach therefore is to start with monitoring & targeting using mainly, existing fiscal meters then building upon it by taking a progressive approach. During this process it is also helping to build relationships with the contractors

and occupants to bring both carbon and costs savings. If not noticed, savings missed are missed forever, so an instant monitoring system is a key to engage contractors by bringing it into a clear visibility to take appropriate actions.
The team has now plans to expand this tool to water management, waste and recycling, monitoring, verification and evaluation of a specific energy savings project to engage stakeholders. It is also useful in validating invoices, budgeting and EU ETS Audit compliance. The Trust also uses to engage their staff and produce recharges for their tenants. .
Quick-wins and motivation
This resulted in bringing the anomalies in energy consumption especially, during out-of-hours and holiday periods into visibility. Following queries and investigations immediate and appropriate

“the tool is simple to understand, and it has helped to bring the energy consumption patterns into a clear visibility – which prompted many questions and helped us identify opportunities” - Jason Davie,
