Inefficient energy performance
Good practice: Application of LED lighting fittings in an elevator car.
Good practice: Use of stainless-steel finishing to maximise illumination in car (by reflecting light). Also results in a more durable elevator car.
Select and design lift equipment that will cater to expected traffic needs with energy efficiency, as attained by proper equipment management in accordance with BS 5655-6, BS 5655-11, BS EN 81-20, SS 550 or equivalent. Adopt the energy calculation and classification for lifts in accordance with ISO 25745-2 or equivalent. For the minimum energy efficiency requirements, refer to SS 530 or equivalent. For the planning of energy efficiency of lifts and escalators, refer to VDI 4707 or equivalent.
Fulfil energy performance and verification of lifts in accordance with ISO 25745-1. Install luminaires which adhere to the maximum lighting power density for lift lobbies; i.e., 7 W/m2. Install equipment to measure energy consumption on installed equipment of lifts with reference to ISO 257545 series (refer also to SS 530 or equivalent).
Adopt the measurements of energy consumption. Implement the energy calculations and classification of escalators and moving walks in accordance with ISO 25745-3 or equivalent. Conduct regular maintenance of the equipment to ensure moving parts are sufficiently lubricated and to identify early signs of wear and tear for timely corrective action and efficient equipment usage. Perform timely modernisation to enhance performance/energy efficiency in accordance with BS 5655-6, BS 5655-11, BS 7255, BS EN 13015, SS 550 or equivalent.
Poor/compromised lighting
Burnt out elevator car lighting bulb.
Lift car should be provided with permanently fixed electric lights (no less than two lighting fittings per car to be provided). Ensure lighting intensity of at least 50 lux at floor level in accordance with BS 5655-6, BS 5655-11, BS EN 81-20, SS 550 or equivalent.
Install emergency luminaires in lift cars in accordance with SS 550, BS 5655-6, BS 5655-11, BS EN 81-20 or equivalent. Use energy efficient lighting with sensors during installation for energy efficiency.
Ensure that luminaires are protected to prevent injury of passengers from breakage; and to prevent access to live parts by passengers in accordance with BS 5655-6, BS 5655-11, BS 7255, BS EN 13015, SS 550 or equivalent.
