BREEAM: the Environmental Assessment Method for Buildings Around the World

Stannah passenger lifts, escalators and moving walkways can generate BREEAM credits which can help the building achieve the best rating possible. Stannah come under the energy section, with the aim to recognise and encourage the specification of energy-efficient transportation systems. More information can be found on the BREEAM website.

By using our platform lifts rather than a conventional lift, the BREEAM count requirement is reduced by two credits, allowing for the whole project score to be recalculated.

Stannah’s passenger lifts, escalators and moving walkways can help you towards your BREEAM rating, contributing up to 2 BREEAM credits by complying to the following:

One credit

1. Where either lifts, escalators or moving walks (transportation types) are required:
1. An analysis of the transportation demand and usage patterns for the building has been carried out by the design team to determine the optimum number and size of lifts (including counter-balancing ratio), escalators and/or moving walks.
2. The energy consumption has been estimated for one of the following: 
1. At least two types of system (for each transportation type required) or
2. An arrangement of systems (e.g. for lifts, hydraulic, traction, MRL) or
3. A system strategy which is ‘fit for purpose’ (scheduling)
3. The lift/escalator/moving walk system/strategy with the lowest energy consumption is specified.

Two credits

2. Criteria 1 is achieved.
3. For lifts, of the following energy-efficient features the three that offer the greatest potential energy savings are specified:
1. The lifts operate in a stand-by condition during off-peak periods. For example the power side of the lift controller and other operating equipment such as lift car lighting, user displays and ventilation fans switch off when the lift has been idle for a prescribed length of time.
2. The lift car uses energy-efficient lighting and display lighting i.e. an average lamp efficacy, across all fittings in the car, of >55 lamp lumens/ circuit watt and lighting switches off after the lift has been idle for a prescribed length of time.
3. The lift uses a drive controller capable of variable-speed, variable-voltage, variable-frequency (VVVF) control of the drive motor.
4. The lift has a regenerative drive unit so that any energy generated by a traction lift (due to running up loaded to less than the counterbalancing ratio or running down loaded to more than the counter balancing ratio) or by a hydraulic lift (due to running down) is returned back to the electricity utility supplier or used elsewhere in the building.
4. For escalators and/or moving walks, each escalator and/or moving walk complies with EITHER of the following:
1. It is fitted with a load sensing device that synchronises motor output to passenger demand through a variable speed drive. OR
2. It is fitted with a passenger sensing device for automated operation (auto walk), so the escalator operates in stand-by mode when there is no passenger demand.

For advice on your lift selection, please contact our customer service team and we will be happy to advise further. We are also able to provide energy consumption figures post installation.
