BU I LDI NG SOLUT IONS
— Nile City Towers
The Nile City Towers is a five stars administration building and the head quarter of the big companies Orascom, Egyptian Company for Cement and Mobinil company for mobile service. The building is composed by 2 towers with 32 floors each and 1280 offices.
The main problem was that the building contained a large number of fan coil units, so there is a high starting current by starting all the fans. The traditional solution for this problem was resizing the electric cables and changing the rating of the installed breakers to higher range, which causes more money, time and reinstallation. Therefore an intelligent solution should be found. That was a challenge to prove the benefits of KNX system. In fact, the solution was turning on the fan coil units in groups with a delay time. That means the first group starts ON. After it reaches the steady state the second group starts ON and so on. This process will be implemented automatically by the time schedule via KNX.
