The Future Build

Masdar City Case Study - Green Elevators

Efficient vertical transportation systems are vital to overall building design.  It is not simply a matter of having enough elevators they must also be energy efficient and specifying key components and system features correctly can achieve significant results.

  • Similar to most products not all elevators have the same lifespan.  However, the typical design lift of ThyssenKrupp elevators of 25 years assists in earning credit when calculating life cycle costing.
  • Power consumption in the utilization phase is typically 70% or more of the total consumption in an elevators life cycle.  Key features such as regenerative inverters and automatic light and fan control, provided by ThyssenKrupp Elevator can reduce energy consumption considerably.
  • Using light weight materials for elevator cabin interior decoration will also reduce energy use since additional energy is required to overcome the increased inertia due to heavy decoration.
  • Elevator energy use is directly proportional to passenger traffic and ThyssenKrupp can provide accurate energy models using simulation techniques to compare the relative performance of different systems. This data which includes both energy consumption and peak power requirements can be used in achieving the required building energy credits.

Working with Masdar’s supply chain team highlighted to ThyssenKrupp Elevator the benefits of Life Cycle Assessment and assisted in the selection of a number of key features and components to achieve the most energy efficient elevator solution which still met the operational and architectural design requirements.

About Estidama

The Abu Dhabi Government has taken the initiative to implement the green building code – Estidama. Estidama has launched its Pearl Rating System which aims to demonstrate the sustainability of a given development throughout its lifecycle from design to construction and operation.

The Pearl rating system is a standard to guide all contractors and architects to select the right ‘green’ material, making their projects more sustainable, and earning more ‘pearl points’ as a result.

Currently, all new projects have to be rated minimum 1 pearl point; therefore Clients, Consultants, Contractors, Architects, and Engineers are now focusing more at the environmental impact of their projects.
