A new boutique city centre hotel is to be constructed for the Boutique Hotel Co. in Kowloon, Hong Kong.
A brief has been given as follows.
The hotel is to be 4* equivalent with a 2-way peak 5-minute lift traffic design criteria of 12% handling capacity and average interval not to exceed 45s.
The operator has specified that room occupancy should be assumed at 1.3 persons per room.
There are 23 room floors above the main lobby where restaurant all other guest facilities are situated. Typical floor to floor distance will be 3.6m.
Each upper floor will consist of 14 standard rooms. Total room count = 322 rooms.
Each floor will therefore have a maximum population of 14 x 1.3 = 18.2 persons (say 18).
Total hotel guest population = 23 floors x 18 persons per floor = 414 persons.
The hotel operator does not want to use a lift capacity less than 1275kg for luggage handling and aesthetic reasons. Guest lifts should also have centre opening doors of minimum 1100mm width. A minimum door height of 2300m is required with a clear height to the underside of the ceiling inside the car of 2400mm.
Service lifts must accommodate a stretcher. Minimum of two are to be provided of 2000kg capacity. Service lift numbers to be 50 to 75% of guest lift numbers. A minimum clear entrance width of 1300mm is required with 2400mm high doors and 2600mm clear internal height.
