  • How can lightning affect your home elevator?

    How can lightning affect your home elevator?

    EM – From 3:00 PM to 5:45 PM on July 30, 2025, Northern Vietnam recorded 81,486 lightning strikes, of which 14,529 were cloud-to-ground strikes. What potential issues could arise for elevators during such extreme weather conditions?

  • Hospital evacuation in case of fire

    Hospital evacuation in case of fire

    EM - Hospital evacuation in the case of fire is a complicated challenge because the main subjects are patients with limited mobility or those dependent on medical equipment. This article will clarify the stages of evacuation and the characteristics of different patient groups in case of an emergency in a hospital.

  • Hospital elevator design handbook: Selecting elevator size and capacity based on elevator type

    Hospital elevator design handbook: Selecting elevator size and capacity based on elevator type

    EM - With the characteristics of hospital buildings along with different function requirements for different types of elevator, each hospital elevator require a different approach in size and capacity, instead of a one size fit all solution for the entire building.

  • Hospital elevator design handbook: The difference in hospital elevator design according to Vietnam Standards and ISO 8100-30

    Hospital elevator design handbook: The difference in hospital elevator design according to Vietnam Standards and ISO 8100-30

    EM – Healthcare centers and hospitals require many types of specialized elevators, each designed for different specific purposes. As such, they also have different size and capacity requirements. However, elevator size requirements in Vietnam Standards regarding healthcare centers and hospital design has relatively simple classifications and is lacking in details.

  • Part 3: Heat, smoke, and elevator shaft ventilation

    Part 3: Heat, smoke, and elevator shaft ventilation

    EM - Over time, technical studies, practical experience, and tragic incidents have demonstrated that elevator shaft vent openings do not deliver the intended effectiveness. On the contrary, they often pose critical life safety issues in the event of a fire.

  • Part 1: Re-evaluating the ventilation of elevator shaft

    Part 1: Re-evaluating the ventilation of elevator shaft

    EM - Elevator and building standards, along with longstanding design conventions, have traditionally required the installation of a ventilation opening at the top of the elevator shaft. However, this requirement has recently been re-evaluated and determined to be inappropriate and largely ineffective.

  • Part 2: Airflow movement within the elevator shaft

    Part 2: Airflow movement within the elevator shaft

    EM - When ventilation openings are installed in the elevator shaft, they accelerate the movement of convective airflow between the interior and exterior of the building, thereby intensifying the stack effect and exerting a greater impact on the elevator’s operation.
