E.ON recently delivered bespoke solutions for Premier Inn and Beefeater operator Whitbread to help the firm, which runs a number of hotels, restaurants and coffee shops, reduce emissions and improve its energy efficiency across its property portfolio.
For the large-scale, multi-site energy management project, a range of solutions were successfully put in place, each tailored to the client’s specific needs and resulting in a significant energy use reduction.
E.ON’s challenge was to help Whitbread achieve new carbon reduction targets across its estate having reached its carbon target well ahead of schedule. The task was made tougher because Whitbread did not want its customers and guests to be negatively impacted by any new energy management strategies. The firm sought to find a solution that monitored energy consumption and provided tangible energy efficiency gains at a diverse range of sites with differing demands.
E.ON’s solutions looked at bringing an integrated approach which brought together a range of solutions that satisfied the demands of each site. In the beginning, E.ON monitored an initial 90 sites. Each had its own set of operational requirements and required various installed equipment to function optimally. Those sites were remotely connected to E.ON’s 24/7 Energy Management Centre to monitor consumption and operations. From the data captured, a tailored package was developed and delivered to each site on a case-by-case basis.
Tom Montali, Customer Accounts Director at E.ON, said: “Within the hospitality industry it is imperative that major works do not impact on the experience or comfort for guests. Whitbread needed to find a solution that delivered the energy consumption savings required whilst taking account of the different building styles and sizes as well as operational demands. With differing demands and challenges our solution was flexible enough to deliver the savings required whilst maintaining customisation for guests’ expectations.”
The result, in some cases, is energy reduction of around 35%. And some sites have delivered higher than expected energy efficiency. Currently, overall data is ahead of expectation – with a 12% average reduction – and on course to exceed the expected return on investment.
Montali adds: “The data intelligence gleaned through our systems enabled us to focus on sites with the largest potential for improvements and were designed to maximise the potential savings compared to a more traditional rollout programme.”
Having set itself a carbon target to hit by 2020, Whitbread was looking to develop an energy reduction strategy for consistency across brands and units through big data driven insight, energy efficiency capital investment and better management of energy consumption.
Combining multiple data sources including half hourly electricity and gas meters, weather impacts and existing data from building energy management systems as well as site-specific factors such as solar generation, combined heat and power plants and business information such as hotel occupancy and restaurant covers into E.ON’s data management system provided Whitbread with a new level of understanding of its estate.
Cian Hatton, Head of Energy and Environment, at Whitbread, said: “As one of the first in the hospitality industry to use remote energy management across our sites, we trialled several different energy suppliers to find a system that provided detailed feedback across multiple buildings. E.ON’s integrated approach and range of solutions spanned our entire energy strategy, from big data to investment including ongoing control and support– providing an effective hardware and software partnership.”
