New York’s Mayor to Ban Elevator Use?

Mayor Bloomberg

Mayor Michael Bloomberg of New York is known for his stance on healthy living. While he isn’t going to outlaw elevator use, he is going to encourage New Yorkers to take the stairs. Mayor Bloomberg has been fighting obesity all three terms he has served.

This isn’t Mayor Bloomberg’s first battle with obesity and unhealthy practices. He has created a program discouraging salt consumption, passed a ban on outdoor smoking, supported a one-cent tax on sodas, and even campaigned against school bake sales. The mayor’s newest campaign is to encourage New Yorkers to skip the elevator and take the stairs.

Bloomberg wants buildings to start being designed to promote physical activity. He is fighting hard to make exercise “cool” and to get the people of New York to embrace a healthier lifestyle. Bloomberg announced that his newest executive order would require all city agencies to incorporate active design strategies when implementing major renovations or new construction. Two pieces of legislation will be sent to the city council by the mayor that will promote the use of stairs.

The first proposed bill would require building owners to give stair access to occupants and post signs near the elevators that would promote the use of the stairs. The other proposal would require access to stairways and would promote stair usage through the use of hold-open devices in at least one stairway per building.

Mayor Bloomberg is making a valiant effort to make New Yorkers healthier. He is working with the Center for Active Design to find ways to design healthier buildings, create more inviting outdoor spaces, and promote public transportation. Would you skip the elevator for the stairs?

China’s Tallest Building will have World’s Fastest Elevator

Shanghai TowerThe main structure for China’s Shanghai Tower is almost completed and will be the nation’s tallest building, for now. Skyscrapers are getting taller and taller around the world, pushing architects to create better buildings. Shanghai Tower will be the tallest building in China until Sky City is built. However, one thing that the Shanghai Tower will still have is the world’s fastest elevator.

The Shanghai Tower needed an 18 foot deep foundation that required 63 hours of non-stop work to pour. Once the massive structure is finished, it will contain more than six million square feet of office and retail space that is expected to attract an estimated 16,000 people per day. While the building will only be China’s tallest until Sky City is finished, it is still a spectacle.

The tower’s 90 by 90 foot concrete core will be surrounded by a layer of glass that will insulate the building and regulate its energy consumption. There will be atriums with ceilings high enough to house trees as tall as 10 meters. There will be 121 floors, which guests will travel between in the world’s fastest elevator. The elevator will be able to reach speeds of 40 mph, getting riders to their desired floor faster than any other commercial elevator ever built.

Shanghai Tower (2,073 feet) will be the third tallest building in the world, behind the Burj Khalifa (2,717 feet) and Sky City (2,739 feet). It will be one amazing structure that will be able to boast it has the world’s fastest elevator.

Solar Powered Elevators on their way to the U.S.

solar powered elevator

Americans may be riding in elevators running on solar power by as early as 2015. The first people to get this experience may be in the nation’s capital. A Washington, D.C. area real estate firm called Akridge is teaming up with the Switzerland based Schindler Elevator Company to bring the solar powered technology to the United States.

Solar powered elevators are already being used in Europe today. The commercial elevators powered by the sun in Europe utilize rooftop solar panels and are able to function separately from a city’s power grid. The solar panels capture energy and store it in batteries, allowing the elevators to operate at night or during a power outage.

These green elevators should be available in India and more locations in Europe by the end of the year. Schindler hopes to put the solar powered elevators into U.S. commercial buildings by 2015. The solar powered elevator is part of Schindler’s effort to create more efficient and environmentally friendly ways to move people.

Schindler continues to make strides in solar technology. They are also a partner in the Solar Impulse Project, which is developing a solar powered airplane. Renewable energy is going to be very important in the near future and Schindler is doing what they can do help prepare. Their solar powered elevators should help reduce energy consumption and make the world much greener.

Elevator and Escalator Sales Growing Worldwide

India Elevators

A recent survey found that the increase in commercial space and infrastructure development are major drivers for the growth of the elevator and escalator market in India. The development of more mega cities gives a strong anticipation for a need for more elevators and escalators.

India’s economy has shown a steady growth of five to six percent over the last two to three years, despite global recession. Because of this, the real estate market in India is booming. It is estimated that real estate projects will reach $265 billion in 2020, over $150 billion more than in 2010. High disposable India Escalatorsincomes, a young workforce, and a large base of middle-class households will help India’s economy and real estate market thrive.

It is expected that India will have 25 mega cities with populations of eight million or more with a GDP of $250 million. The country also expects to experience the creation of four mega regions by 2025, each with a population of over 15 million. All this growth equates to more commercial buildings. As the mega cities expand, the building will soar higher, creating a need for commercial size elevators and escalators.

Currently, elevator sales in India are between 40,000 and 45,000 units per year. This is a big leap from the 15,000 units per year that were being sold ten years ago. The market is not just in commercial elevators either, more than 50 percent of the elevator sales in India come from residential elevator purchases. More high rise apartments are being built to accommodate the growing population, causing the elevator market to grow and expected 15-17 percent in the next five to seven years.

How do Architects Decide how Many Elevators a Building will have?

Office Elevator

The number of elevators, along with their size and speed, that a building will have is determined by several factors. The design of the building, number of floors, usable areas of each floor, and height of each floor all factor into how many elevators are installed.

There are two main factors that determine which type of elevator system will be required. One is the population to be served and the other is passenger waiting time.

Population to be Served

First the architect needs to know the number of people the elevators will be transporting. This can be a tricky figure to calculate. They figure it out by calculating the total population of the building, which can sometimes be unknown. Once the population is estimated, they need to figure out who wants to go where and at what time. For office buildings, peak traffic time is normally the morning, lunch time, and evening. However, for an apartment building it can be completely different.

This is where traffic analysis comes in. This will help figure out peak travel numbers between various floors at various times and duration of peak travel time. Traffic Elevator Waiting Timeanalysis will also take into consideration people using other modes of transportation such as stairs or escalators. After all this data is collected, what the waiting time should be needs to be decided.

Passenger waiting Time

This is one of the most important numbers when figuring out building performance. Typically people are more impatient in an office setting than residential ones, so waiting times tend to be much higher in apartment buildings. There are standards set in place based on previous studies for what is an acceptable waiting time. Usually office buildings want to keep wait times under 20 seconds, while apartment wait times can reach up to 90 seconds. Ideally, elevators should be designed to serve a maximum number of people with minimum waiting time at the worst peak times to help disperse the population quickly. Unfortunately this is usually hard to achieve because it would mean having a large number of elevators and that is financially not always an option. Commercial elevators can be expensive, require more energy to operate, and occupy a huge floor area, decreasing the amount of usable space.

Round Trip Time

Lastly the number of elevators that will be in a building depends on the type of elevator itself. This plays a very important role in the calculation of round trip time. Round trip time is used to determine how many elevators are needed. It is the average time taken by a lift to complete one trip, from the main lobby to all the floors of the building and back, during peak traffic.
