Problem to be solved

Clayton Hotel Cardiff Lane had a history of high consumption and unaccounted for energy spikes which costed the hotel extra thousands of Euro each month. They required a solution that would help them to quickly identify and alert them to periods of excessive consumption, unplanned energy spikes as well as other areas of operational waste – to reduce kWh expenditure, energy costs and improve overall energy efficiency.

The hotel’s maintenance management department also found several energy inefficiencies eg. AC was left on in non-critical areas during off-peak times and multiple fans were manually overridden to “on”.

Clayton Hotels’ Leisure Centre was found to be one of the highest energy-consuming areas 


Sub-metered areas and appliances such as air-conditioning units, fans, pumps, electricity main (DB) were monitored by smart meters and connected to Wattics. Incoming data from monitored circuits was ready for analysis in a matter of minutes. With the Wattics platform, Clayton Hotel Cardiff Lane is able to:

  • Monitor and track energy consumption in real-time
  • Get remote access to consumption information and receive automatic data updates for all its monitored sites
  • Alert/notify facility personnel of energy spikes and abnormalities in consumption so that immediate action can be taken
  • Perform operations wastage analysis to identify areas of energy waste and opportunities for savings
  • Benchmark and compare energy consumption trends
  • Save time and money, having a unified platform through which all monitored circuits consumption data is visible. No more manual data collection.
  • Incorporate historical data to view trends over time
  • Work with an easy-to-use platform and interface to get the job done
  • Document energy analysis and savings for dissemination


• Clayton Hotels Cardiff Lane has saved hundreds of thousands in kWh and thousands of Euro in energy costs since working with the Wattics platform in 2014 (Figure 1).

• Wattics alerted Clayton Hotels Cardiff Lane to a spike in energy consumption in the first quarter of 2019 (see Figure 2), coinciding with a report from its energy supplier that its energy supply costs reached approximately €31,000
