Grand Hotel Copenhagen (Grand Joanne) to be transformed into an energy machine

September 19, 2022

Energy Machines, on behalf of Midstar AB, is transforming Grand Hotel Copenhagen into a high-performance energy machine. The hotel will be re-launched as Grand Joanne.

The historic building, built in 1892, is undergoing a complete renovation which includes the implementation of a brand new carbon-conscious integrated energy system.

Energy system components:
2 x 120 kW Energy Machines heat pumps (pictured, in what will be the hotel's basement)
2 x 5000L/min and 1000L/min ClimateMachines air handling units

Software-based integration of the two technologies ensures the hotel’s entire cooling demand is achieved by the solution and that grid-based heat consumption will be lowered by 90%.

The project will result in significant reductions in the hotel’s operating expenses and carbon footprint. Hotel guests and staff can expect a reliably clean, comfortable, and environmentally friendly indoor environment for decades to come.
