Costa – Stimulating Engagement with Customised Energy Analysis
Discover how high-quality data was essential for evaluating the efficiency of new equipment and accurately reporting on the energy reductions achieved across the Costa portfolio.
“I find SavenergyOnline invaluable to be able to analyse consumption based on a range of parameters such as occupancy, floor size, opening hours and even the weather. I can’t think of any information that I need that I can’t get from SavenergyOnline.”
Costa Coffee is one of the largest chain of coffee shops in the world and the fastest growing in the UK with over 1,200 stores nationwide. Part of the Whitbread Group, Costa has set challenging targets to reduce energy consumption as part of its business growth strategy and made significant progress improving the management of energy within stores.
The first step was the roll-out of Automatic Meter Reading (AMR) devices across its portfolio in 2009. Since then the energy team has achieved significant reductions in energy consumption, both through investing in energy efficient equipment when refurbishing stores and more recently by engaging with staff at store level.
Extensive, high-quality data was essential for evaluating the efficiency of new equipment and accurately reporting on the energy reductions achieved through these interventions.
In addition to acting as Costa’s chosen Data Collector and Aggregator (DC/DA), Stark was commissioned to develop a customised data solution to meet the needs of Costa Coffee and fulfil the technical requirements of their consultant. Stark provided assured and actual energy data to the consultant on a weekly basis and created historical baseline data profiles for new sites to facilitate the programme.
Step 1: Introducing Energy Efficient Equipment
The Costa energy team was able to directly access energy data through Stark’s reporting platform SavenergyOnline. The ability to monitor energy data using the range of tools available on SavenergyOnline was fundamental to successfully trialling different equipment and assessing the impact of refurbishment on a store’s energy efficiency.
Step 2: Custom Data Provision
In addition to empowering the Costa Energy team to make the best use of their data, Stark worked closely with a specialist consultant to develop an advanced and customised data export that granted detailed visibility of meter flags and data under investigation. This process ensured that Costa’s consultant had complete visibility of the data provided by Stark.
Step 3: Baselining New Stores
Much of Costa’s reporting tracked performance by comparing against historical data, which presented a problem for new sites where no historical data had been collected. A baseline yearly profile was needed to compare these sites without having to wait a year for the actual energy consumption data.
Through rigorous analysis of the impact of seasonal variation, floor size and store type on a store’s overall energy consumption, Stark’s Energy Analytics team developed an innovative model to generate the required baseline profiles. The accuracy of these modelled baselines meant employees weren’t discouraged by receiving reports with missing data or unrealistic targets.
Since 2009 the introduction of energy efficient equipment has led to a 32% reduction in energy consumption and this performance will be maintained, if not improved through engaging employees.
The energy reduction programme adopted by Costa operates using rigorous data standards to maximise employee engagement. Stark’s Energy Analytics team were able to deploy their substantial experience this data analysis to develop an innovative approach that exceeded the expectations of the customer.
