Energy Efficient

Is my lift energy efficient?

Technology development in the lift industry has mainly been driven by factors other than energy efficiency. Safety, travel speed, acoustic noise, ride comfort and occupied space are, traditionally, the main concerns in lift design.

However, in the last few years the demand for energy efficient products and greener buildings has grown and the lift industry has responded accordingly, presenting its customers with solutions to meet these growing demands. Energy efficient technology developments take different approaches that tackle different causes of inefficiencies in vertical transportation systems. These causes can be divided into two major groups: direct and indirect.

Direct causes are the ones that can be directly related to the equipment

Friction
Brake
Transmission
Lighting
Motor
Controller

Indirect causes are related to the operation of the equipment and are associated with user behaviour or traffic management options.

EU regulations impact indirectly on lift performance relating to the energy efficiency of new buildings, setting strict targets for carbon reduction.

Building regulations monitor the majority of energy consuming equipment with the aim of improving the buildings energy efficiency. Lifts are thought to consume between 5% and 15% of a building’s energy, more than 50% of this could simply be down to car illumination!

Typical solutions to improve the energy efficiency of your lift:

Modern variable frequency drive units
Sleep mode when not in use
Regenerative drive systems
Heat recovery from lift motor rooms
Eco efficient car lighting
Ensure optimal maintenance
Ensure well equipment is correctly set up
