Steigenberger Hotel Hamburg lies in the very heart of the metropolis at the river Elbe in northern Germany, with its typical hanseatic architecture and a direct view of the Alsterfleet. There are shopping arcades in close proximity to this luxurious hotel. The historic council house, the center and the Speicherstadt as well as the HafenCity are very close by.
The 5-Star superior hotel has 233 Rooms on 7 Stories, 2 Restaurants, 8 conference-rooms, complete with a full-service-wellness-area with steam bath and sauna.
The hotel was built in 1992 for the Steigenberger Hotel Group. All hotel rooms as well as the spa-area are fully air-conditioned which means that roughly 130.000 m³/h are required to supply the whole building with conditioned air.
To meet the hygienic standards according to VDI 6022, the hotel’s technicians have been applying the proven filter-class F7 according to DIN EN 779:2012 within the incoming air-levels. Filter-class F7 means a very high protection against particulate matter in urban surroundings.
Since Mr. Düx has been assisting the hotel, he has set great store on impeccable operations and also to meet all the latest requirements and standards in order to provide the best possible air to the hotel guests as well as to protect the hotels facilities.
Efficient F7 particulate filters separate more than 50% of particulate matter (0,4μm particle-size) from the outside air and therefore have higher pressure losses than pocket filters of classes M5 or M6. In order to be able to run their system with an efficient particulate filter in a way that saves as much energy as possible while ensuring hygienically impeccable results, the technicians at Steigenberger Hotel have chosen the energy-efficient PM1 pocket-filter .
This new air filter has a pressure loss of merely 71Pa per year, which means a full 100Pa less than traditional F7 pocket filters. These low pressure losses with equal air quality in a modern frequency controlled facility amount to savings of over 50.000 kWh/year. The FU-regulation permanently controls the pressure loss within the system and automatically regulates the engine-frequency. Now if the pressure losses within the installed filters rise more slowly, the fans need to provide less air, using less energy.
If you consider, that one kWh costs 13 Eurocent, it becomes clear that the replacement of the filters has benefits for the Steigenberger Hotel. Steigenberger Hotel saves €12.000 per year in energy costs without further reconstruction work, just by replacing the filters!
Furthermore, it is an additional step towards Certified Green Hotel by means of reducing the greenhouse gas CO2. Certainly many hotels don’t base their decisions solely on economic savings, but also exceedingly on ecologic considerations.
Mr. Düx of Steigenberger Hotel in Hamburg is very pleased about the collaboration with filter manufacturer AFPRO. With their Eurovent certified air filters they offer the opportunity to save energy costs while reducing particulate matter in their incoming air. The in-house AFPRO calculation-program LCC clearly shows the saving opportunities by simply changing the filters.
