The Etihad Towers - a building complex in Abu Dhabi - consist of five unique towers. Ranging from 54 to 75 floors they offer a hotel, apartments and offices. The highest tower reaches a high of over 300 meters and the whole complex covers half a million square meters.
Offering a total of 884 apartments and penthouses with up to 5 bedrooms, the three spectacular residential towers provide also a wide range of fashion and relaxation amenities. With a total of 602 hotel guest rooms and serviced apartments the hotel tower stretches up over 60 floors. The state of the art office tower features a well-designed infrastructure and proficiently managed facilities.
Furthermore a wide range of shopping facilities, a four level underground car park with a capacity of over 3,000 cars, a large convention center and a grand ballroom for up to 2,200 guests are contained within this stunning complex.
The solution should be economical, easy to operate for the guest and user friendly for engineering, housekeeping and reception staff. Furthermore the system had to be integrable to the Property Management System (PMS) and Building Management System (BMS) by an open protocol. A maximum utilization of energy with less wastage and with high efficiency as well as energy saving via presence sensing instead of a card switch was required. A visualisation which covers the common area control system, current consumption and lamp operation hours was also an requirement which had to be fulfilled.
The customer required a state of the art facility with convenience access to all guest room functions in addition to a multivendor technical platform to be future proof. The common areas such as corridors, basement parking areas and lift lobbies are controlled by a lighting control system. The user interface should be simple, easy to operate and at the same time user friendly for the reception, housekeeping and engineering staff. It was required that the system shows the current consumption for each circuit and calculates the lamp operation hours.
The system detects the occupancy in the guest room and switches between energy saving and guest comfort mode. There is a huge saving (around 30%) by controlling the guest room HVAC, lighting and curtain control system. The system will change the set point and fan speed (fast cooling mode) from the reception once the guest checks in from the reception desk. The lighting control in the common area includes controlling of circuits through time schedule and occupancy.
30 % saving compared with study for conventional GRMS (Guest Room Management System).
