Holiday Inn Express is part of the IHG (InterContinental Hotels Group PLC), their business and hotel brands span the world. As the IHG’s fastest growing hotel brand, Holiday Inn Express are the first choice for the increasing number of travellers who need a simple, engaging place to rest.
The IHG Holiday Inn Express site in Perth has 81 en-suite hotel rooms, two conference rooms and a restaurant with bar area. Hotels are a 24-hour operation and therefore use energy continuously in varying degrees, the addition of the restaurant provides further equipment such as refrigeration and extraction which provides a lot of potential for saving energy.
Based on analysis and working alongside the Perth site Manager, iESCo’s project manager identified the best installation time to cause no disruption to the business. Optimisation settings were set on the powerPerfector optimiser from the logging of the IHG building’s incoming voltage supply in order to maximise the savings. In one stroke the IHG’s site cut energy consumption, reduced costs and emissions, and protected their equipment.
The analysis compared the energy consumed by the site 34 days pre and post the installation of a powerPerfector unit. The step change in kWh was clearly identified resulting in an energy saving of 6.85%. Testing demonstrated the direct relationship between energy used in kWh and voltage – as the voltage is lowered by the powerPerfector unit from ~248V (mains) to ~225V (optimised voltages) the power drawn through the site billing meter reduced.
