Bob Beyer Lecture Key Points

• In the next 5 years 75 of all the elevators will
  be MRL ( Machine room less
• MRLs will replace Hydraulic and Geared Traction
  type elevators
• MRL have lower energy costs up to 60 less than
  geared. (Only 2-3 of the total buildings
  electrical load is for the elevators)
• Machine rooms must be air-conditioned
• In office buildings above 5 floor you should have
  a dedicated service elevator (4500lbs. minimum
  size for service elevator)
• 1 service elevator for every 2 passenger
  elevators in a hotel over 15 stories.
• In the next 5 years al the signs saying Do Not
  Use The Elevator In Case Of Fire will be gone.
  Elevators are the safest way out of a building
  until the fire actually reaches the shafts (
  which are two hour rated in high rise)
