Because they are not high and they cost a lot of electricity
Elevators changed how cities looked more than they changed lifestyles. Without elevators, there wasn't much point in building higher than 4-5 storeys, because no one wanted to walk any further up. But with elevators, it became easy to get to any level. Houses could be built higher and hold more people. Cities could grow in population w/o becoming bigger on the ground. Also, earlier the good apartments were the low ones, maybe one storey off the street. With the elevator, the good apartments were the ones up high. Less road noise and smells, less risk of burglary.
Larger less frequent grain elevators.
Walk instead of driving; climb stairs instead of taking elevators or escalators. Eat less.
To exit a building filled with smoke, stay low to the ground where the air is clearer and less toxic. Use your hands to feel for the nearest exit, and avoid using elevators. If possible, cover your mouth and nose with a cloth to reduce smoke inhalation. If you encounter a door, check it with the back of your hand for heat before opening, and proceed with caution.
You don't, Elevators have a weight limit so they don't break and kill people. Besides, there are so many elevators that would have to change and im pretty sure no one want's to pay for that.
One positive of Thyssenkrupp passenger elevators is that they are eco-friendly. The energy generated by the braking of the elevator is converted into electricity. It is then fed back into the power supply system. Thyssenkrupp elevators also use energy-efficient LED lighting which use less energy and last longer.

Thermal insulation for windows helps to improve energy efficiency in a building by reducing heat transfer between the inside and outside. This means that in cold weather, less heat escapes through the windows, and in hot weather, less heat enters the building. As a result, the building requires less heating and cooling, leading to lower energy consumption and cost.
