Energy Certification of lifts

We are aware of this type of energy classification when it comes to fridges and washing machines but lifts!
Well there are now European guidelines (VDI 4707) that cover the energy efficiency of lifts.

The guidelines provide a basis that makes it possible to establish a generally comprehensible and transparent comparison of lift systems from various manufacturers without complex calculations.

What is the legal situation?

European legislation has an energy efficiency goal of 20% energy savings by 2020 compared to 2005. Buildings use 40% of the overall energy. The goal is a reduction of 30% on building energy by 2020 to help meet the overall goal.

There is a European Directive (2002/91/EC) for member states on the energy performance of buildings. Member States must set a minimal efficiency standard for buildings.

The directive is applicable for new buildings and modernisation of buildings with more than 1000m2 area. Although, it does not specifically mention lifts, lift manufacturers are taking up the challenge to reduce energy.

Bearing in mind that lifts and escalators are thought to consume 3% to 8% of the energy of buildings there is considerable scope on energy efficiency to help meet the target.

All the major lift manufacturers now have this classification on many of their products.

What can be done to save energy on existing lifts?

The answer is surprisingly simple.

All empirical evidence indicates that overall lifts use most of their energy in standby mode i.e. when not moving. This varies according to building type and can be as high as 80% of energy consumed whilst in standby mode.

What can we do to save that energy?

1. Turn off the lights! The majority of energy in standby is usually used by the lighting, so a simple timer function to turn them off when the lift is not in use saves energy.

2. Have a lift control panel with a ‘sleep’ mode. When the lift is not used the controller powers itself down as well as reducing power to many auxiliary devices on the lift.

3. Turn off the fan if there is one.

4. Counter balance the lift at less than 50% if possible.

5. Ensure optimal maintenance: well lubricated and adjusted equipment means it runs smoother with less energy expended.

What can The Lift Consultancy do to help?

If you are planning on installing new lifts we can help specify them correctly, ensuring not only do they meet the needs of your building, but do so utilising the most up to date technology in terms of energy efficiency. We can also ensure that you will get you your BREEAM credits for the lifts in your building.

A few of the simpler things listed above can be done to existing lifts at little costs e.g. timers on the lights and fan, improved maintenance. More significant energy savings can be had when coupled with upgrading equipment. We can help with specification and selection of the correct equipment to ensure you get the maximum energy savings from your replaced components or upgraded lifts.
