Green Elevator

In the beginning there was Archimedes, who in 236 B.C.E. hooked his famous pulleys to the top of a big wooden box and began to pull. Eureka, the elevator was born. Made of locally sourced, sustainably produced materials, his person-powered off-the-grid invention is the distant ancestor of a new crop of eco-friendly passenger elevators now courting the growing green-building market.

Some estimates project that buildings consume about 40% of the world's energy, and elevators account for between 2% and 10% of a building's energy use. The leading elevator manufacturers are rising up to get those numbers down.

What makes an elevator green? Energy consumption is key, but that's just a start. The materials, processes, and technologies that go into the manufacture of an elevator system also count. So too do the choices of interior paints, flooring, control panels, lighting, and HVAC systems. All of these elements can contribute points to a building's overall score for LEED accreditation by the U.S. Green Building Council. Here is a snapshot of how the major elevator makers are addressing these design elements.

Machine-Room-Less Technology

Introduced in the mid-1990s, machine-room-less (MRL) technology was one of the biggest advances in elevator design since they went electric a century before. Miniaturization has made it feasible to house the MRL machinery right in the elevator shaft rather than in a costly rooftop machine room. Incorporating a gearless traction design, machine room-less elevators in some cases can use up to 80% less energy than hydraulic lifts, without the expense and environmental headaches of oil-filled underground hydraulic cylinders.

Ma

KONE, Inc. (Moline, IL) introduced the first MRL elevator and places so much stock in the technology that the company discontinued manufacturing hydraulic elevators altogether. Its EcoSpace MRL elevator design incorporates a low-friction, gearless hoisting apparatus that prevents wear and reduces energy consumption by half compared to a geared system.

Regenerative Drives

Green elevators don't just stop with reducing energy consumption — some of them give back much of what they take. Regenerative drive systems recover energy that would normally be dissipated as heat and put it back into the building's electrical system. Not only does the technology produce power for lighting and air conditioning, it also saves money by reducing the need for machine-room cooling. Regenerative drives reduce power consumption during peak periods, contributing to a building's overall operational bottom line. Most of the major players offer this technology.

Control Features

It's a matter of physics: elevators without very many pass

engers aboard require more energy due to the weight differential between the elevator and its counterweight. A major goal of green elevator technology is to cut down on these light loads through precision traffic control, management of interior lighting and other energy-burning factors.

Con

Novel computerized systems help reduce the number of light-load trips while ensuring that there are enough elevators in operation to provide fast service. Schindler's systems offer an Energy Control Option (ECO) mode that switches unused elevators into standby. If waiting times become too long, the system will activate additional cabs to meet the need. ThyssenKrupp (Memphis, TN) says its Destination Dispatch system improves handling capacity by 15-30%. The system monitors and controls the amount of current delivered to the motor, ensuring the correct level to provide to keep the motor running at full speed. As a result, the motor is protected from peak over-currents, potential overload and sudden power surges.

Outside the box

Green elevator technology isn't limited to what's in the shaft. Companies include external factors in their sustainability bona fides that contribute to a lower overall carbon footprint across the elevator's life cycle while reflecting their green corporate values. Customers considering an elevator vendor can evaluate the energy-efficiency of its manufacturing facilities, service fleet management practices, remote monitoring technologies for early diagnosis of mechanical problems, and other support systems.

Elevators will never again be as eco-neutral as it was back in Archimedes' day, but it's clear that green elevator technology is on the way up.

elevator and city

The beginning of the industrial revolution in eighteenth Century declared the beginning of urbanization.　By nineteenth Century, he original land area can not match the growing population density .The rapid development of urbanization from the objective requirements of the construction sector in the intensive aspects of innovation.

Before 1852 Otis invented the safety lifting device,  buildings more than 6 floors are relatively rare.　People do not want to climb too many steps, while the hydraulic vertical lift can enhance the height of only 15 meters. Before　the elevator show up, the loft and the top floor is regarded as a grocery, laundry, or for servants and poor living.In the early stage of the elevator, its safety is not fully accepted, it only meets the needs of the people in the office area of high-rise buildings in the physical movement.Until 1920, the New York developers launched the "top floor apartment" (Penthouse) , so that the top floor or the floor with a balcony to become a rich man's patent.They can even build their own private residential elevator, blocking outsiders.

Often encounter with a stranger in such a small space, there will inevitably be some embarrassing thing to happen.So, the design of the elevator space should consider both comfort and safety.In nineteenth Century, the elevator door can not automatically open, need to switch on people own.We often seen well dressed   elevator operator in the old movie , in fact, is a kind of security.In 1887, the elevator door of automatic switch appears.The invention of automatic elevator door keep passenger away felling into the shaft cause of forgetting close the door , also let the elevator process more of a sense of security and privacy.

After years of exploration and evolution, the modern standard passenger elevator space design is recommended for each passenger to occupy an area of at least 0.19 square meters.This elevator design also can maximize the end of overweight, to ensure safety.Culture also has an impact on the elevator design.In fact, Asians have a greater degree of acceptance in crowded spaces.

With the development of technology, the height of the building is relatively easy to achieve, and the focus of the competition transferred to the elevator speed, comfort, security and creativity.Built in 1930, New York's Chrysler building, 318.9 meters high, with 77 floors, the elevator running speed is only 4.5 m / sec.By 2004, 509 meters high Taipei 101 tower , a total of 106 floors, the elevator running speed reached 16.8 m / s.

In the place with large flow of people, the escalator can effectively relieve congestion.Compared with the elevator, the electric escalator occupies more space, and the vertical speed is relatively slow.　But because of its continuous operation, there is no need to wait, making its total capacity is much higher.　

For 150 years, the elevator continue to emerge in the material, style, control systems, control systems .　There are many kinds of elevators, but the premise condition of all kinds of elevator is still in the continuous improvement of its safety performance.The elevator has also developed its own enjoyable function , and some of the elevator even become a cultural landscape.

　　

Key point to passenger elevator

Passenger elevators transformed the way we build. Buildings of just a few levels extended to skyscrapers because an elevator makes navigating multiple levels far easier for us to accomplish. In recent decades, development of the elevator has reached new heights. Today, passenger elevators are an integral part of most multi-level buildings, designed to recognize our destination and take us there safely in seconds.

Safety First

A transforming moment in the lifetime of the passenger elevator was the development of a safety brake by Elisha G. Otis in 1853. If a hoisting cable broke, this device was immediately engaged to hold the elevator in place. These days, elevators are fitted with intuitive safety features like overload sensors that prevent an elevator from responding unless excess load is removed or some passengers disembark.

Refreshing Air

Stepping into a passenger elevator we're not immediately thinking about the air we breathe. Often we're focused on our destination. Often we take the air conditioning in an elevator for granted. Without it, we would quickly notice how unbearably hot an elevator can be. Air conditioning in elevators is essential, contributing cool in summer months and warmth in winter, ensuring air is being circulated and passengers are kept comfortable.

A Quick Journey

Humans tend to be obsessed with time. We are considered tardy if we arrive late, thought of as wasteful if we spend too much time on a task. And for most of us, it's natural to want any time in a confined space like an elevator to be limited. No wonder then, that increasing the speed of passenger elevators is a constant focus of innovation, with many engineers coming up with grand plans. It is possible these days for elevators to be so fast they race through an elevator shaft at a rate of 3,313 feet per minute.

Comfort and a Smooth Ride

Elevating a passenger's level of comfort in a multi-level journey is the priority of experience designers. Introducing melodic music to passenger elevators in 1889 encouraged first-time passengers to trust elevators would keep them safe, distracting their attention and providing comfort. In today's high speed elevators, buffers in the lift shaft, improved car structure and low friction hoisting ensure a smooth ride.

Functional Finishes

Creating a dreamy experience in a passenger elevator strongly depends on lofty ideas. Once the basics of comfortable acceleration and safety are satisfied, passengers look to functional finishes and control panels that will enhance their experience in multiple journeys. Sleek glass and polished metal finishes create a great first impression and provide durable performance.

An Elevating Experience

Mostly, passenger elevators have become so much a part of our everyday lives we rarely think about how truly extraordinary is the technology that inspires their design. Elevators have inspired skyscrapers and continue to motivate designers towards more outstanding design and luxurious experience for humans intent on rising up to meet the challenges of the day.

Future elevator

The future development of the elevator is not only in terms of speed or length , but also has emerged many concept elevators beyond imagination .

In 2013, a Finland elevator company developed a super lightweight carbon fiber super rope (ultrarope).Its length is far greater than the existing elevator rope, up to 1000 meters.The development of the rope spent 9 years, the finished product will be 7 times lighter than the traditional steel wire rope, less energy consumption, and the service life is two times long than the former.The emergence of super rope is another liberation of the elevator industry.It will be used in the Saudi city of Chittagong Kingdom tower, the tower is expected to be completed in 2019, about 1600 meters high.If this skyscraper was successfully completed, 2000 meters high building is no longer a fantasy.

The intention to subvert the elevator technology company is not only this one, Germany's elevator company in 2014 announced that its future of the new elevator technology MULTI has been in development phase. They use the maglev train design principle, to get rid of the traditional traction rope, lifting wells make quick lifting elevator.  The company also claimed that the magnetic levitation system will enable the elevator to achieve horizontal transport, a number of transport tanks to form a complex circuit, more suitable for use in large population density of large urban construction.

The most ideal elevator should be able to move both horizontal and vertical direction.In this way, the form of the building will no longer be limited.What about beyond the earth?By the United States Aeronautics and Space Administration (NASA) former engineer Michael Ryan founded the elevator group company announced,it is easier to build a space elevator on the moon than on the earth, the company can build a space elevator on the moon by the available technology, and that this idea can become a reality in 2020.

In March 23, 2005, NASA announced the space elevator project has become the preferred century challenge.Russia and Japan are also not resigned to playing second fiddle.Japanese construction company Dalin group, the initial program of its space elevator, installed on the orbital station of the solar panel is responsible for providing energy for the space elevator.elevator cabin can accommodate 30 tourists, the speed of about 201 km / h, only a week or so can enter the distance of about 36 thousand kilometers of space on the ground.

If there is no elevator on the earth,human beings will be limited to on the ground.Without an elevator, the city would have no vertical space, no dense population, no more efficient resource utilization;Without elevator, there is no rising high-rise buildings, so that humans can not create a modern sense of the city and civilization.

　

Elevator history from Archimedes to Dubai Burj

Egypt Pyramid Giza group is one of the seven wonders of the world.Khufu Pyramid is the biggest and most preserved one,which is 146.6 meters high, and 230.5 meters long.It is made up of about 2000000 pieces of stone, each stone weighing 2.5 tons to 15 tons.According to multi inference, to transport such a huge amount of stone to the top of the pyramid, and finish the building in a few decades,it need more than 100 thousand human to work together.

Human society has the need of vertical transportation for a long time.In ancient Greece, Archimedes improved the lifting device with pulley and rope as the main component.He designed a drum hoist driven by the human, it is regarded as the originator of modern elevator.BC 100 years Chinese appeared shaduf and windlass they are composed of a lever, the evolution of the drawing tools, and popular in the spring and autumn period.80 BC, the gladiators and animal who ride lifting equipment very primitive from the ground up to the colosseum.

In 1203, a monastery near the French coast made a huge wheel tread.Through the rope winding in solid pillars, the donkey provides motivation to lift weight.During this period, the lifting of heavy equipment is mainly used for agricultural production and life.By eighteenth Century, the mechanical power was applied to the elevator

 The romantic Louis fifteen gives it a new function: he has built a private "flight ladder" in Palace of Versailles to meet his mistress on the high floor.

But so far, the elevator was still a fundamental safety hazard: once the cable fault, the load platform will crash.Fortunately, in 1852, the American Elisha Graves Otis solved the problem.He installed a special spring buffer at the top of the lifting platform, which was connected with the traction rope.When the elevator is suddenly falling or the spring buffer is hit, the safety device is touched by the spring force, and the guide rail is clamped.This is the world's first steam engine as a driving force, equipped with a safety device of manned lift

After the research and innovation of generations, the security system of the elevator is quite perfect right now.The safety device of the modern elevator includes the brake, the governor, the brake and the buffer, the more advanced elevator may also have the earthquake sensing device and so on.These safety facilities have been many angles to consider testing, to ensure that the elevator speed can be controlled, in order to protect the passengers in the elevator.

In fact, let the public have confidence in the safety of the elevator, it is another important contribution from Otis.In 1857, a New York Broadway department store firstly used an elevator Otis invented.The mall is only 5 floors high, the elevator running speed of 40 feet per minute.Today, the tallest building in Dubai, Harry Fatah (also known as Burj Dubai), 828 meters high, along with a total of 169 layers of underground.A total of 56 al  passengerelevators and freight elevator is running in the building , the average speed can reach 10 meters per second.

The eastern and Western culture in the elevator

20 years ago, a friend from Beijing went to Hongkong. After his return and he talked about his feelings:Hongkong is just like Beijing,has a lot small alley, but Hongkong's alleys are vertical.Vertical alley up and down, all by the elevator. Lift and democracy are the same as the good stuff, not only practical, but also can observe the vicissitudes of life.

Here is a story of taking elevator in France.Just arrived in France, a friend told me about notes of taking passenger elevator .If you are not alone in the elevator, do not forget to let the ladies go first.After the ladies went out,the gentleman would like to let each other go first,and said: "APRESVOUS"(After you).

Some time ago the "Wall Street journal" published Chinese Yuan Li’s article, talking about taking the elevator in New York.She was amazed that  no one in the elevator push the close door button,instead a lot of people will press the key to keep the door open.

A few years later, when the lady back to Beijing, found that the level of Beijing has a lot less alley, the vertical alley has been comparable with Hongkong.She is in Beijing on the first day because in the elevator just stood aside, not to close the door key and lynched.Although the same ladder that person did not say anything, but his eyes and press the action has been the key to his dissatisfaction with the very clear.She soon discovered that in Beijing, almost everyone will press the door close button after come into the elevator .One morning, when she was in the habit of opening the door keys and a young man into the elevator, and he came up and politely.But after that he just keep his hand on the key bottom.Every time after someone comes in,he press the closing bottom to close the elevator door.He didn't mean to, because he seemed to repeat as a habit.For him, there was nothing more important than saving for a few seconds.

Time is money, we can understand that.The above example is the elevator inside the action, if someone press the elevator button, waiting for you on the elevator, what would you do?Generally speaking, most people see the elevator was waiting for him, will do like to speed up the trot, not to delay the time of others.Not just case it will save time,also to show his best try.If he did not try to run,it will be regarded as a rude behavior.

So, attitude means everything.
