«The inherent relativity of group characteristics enables selection of group configurations, which facilitate optimal performance for specific buildings or building zones. Stress tests prove and demonstrate the relativity of group service qualities and group configurations, i.e. make the performance potential of groups transparent for building owners and architects.»
Groups with intelligent destination group controls facilitate:
- Optimal performance for all traffic conditions. This implies transport capacities are maximized and time-dependent service qualities minimized under all traffic conditions.
- Exact planning of optimal group configurations for specific transport capacities and time-dependent service qualities.
- Existing groups with flawed configurations will deliver their group specific optimal performance after conversion to intelligent controls.
- Traffic simulation enables confirmation of the optimal performance of intelligent groups.
- The transport capacities and time-dependent service qualities of intelligent groups are subject to contractual guarantees.
- The recorded data structures of installed groups confirm the guaranteed performance- and traffic simulation data.
- Intelligent groups with optimal configurations minimize energy consumption and space requirements.
- Intelligent groups with more and smaller cars facilitate optimizing of the number of floors served. Consequently, capital- and maintenance costs per floor served are less.
- Intelligent groups encourage in-line group configurations and groups with uneven numbers of cars. This implies additional potential for optimizing hoist way and lobby space requirements.
- Management of permitted stops enables intelligent groups to avoid short waiting times to optimize time-dependent service qualities for all passengers.
- Optimal positioning of cars in the virtual “string” of cars enhances the quality i.e. the consistency, of time-dependent service qualities.
- Groups with many small cars may idle one or more cars during light or medium traffic conditions. Reducing energy consumption and making these cars available for other services.
Each additional car of a group allows a reduction of the contract loads of all cars. Under all traffic conditions, the smaller cars make less stops because more cars imply less stops per car. Service frequencies increase, travel- and waiting times decrease. These simple rules of relativity apply for any group control system, including traditional groups. For an example, refer to chapter 5: Traditional elevator planning, page 4.
Intelligent groups with optimal configurations reduce energy consumption by at least 25 % in comparison with existing groups.
Comparisons of intelligent groups with existing groups will often reveal a much higher energy saving potential.
When the first group with intelligent groups is completed, all elevator companies will adopt intelligent group controls. The same happened during the 1980’s, when destination controls were re-introduced by the Schindler group.
