VerticalCity Sluisbuurt V2

Due to increased demands for energy efficiency, affordability and shifting work patterns, cities will need to be denser and taller in the future. 2

VerticalCity Sluisbuurt

On a global scale we are witnessing this phenomenon as one of the best ways to accommodate a global population of 9 billion-plus people and with that an increasing demand for urban style living.

VerticalCity Sluisbuurt

The city will need more vertical density to make room for a growing population of many types of people from the well off to the less fortunate. 6

How can a clever use of higher densities relate to different demographics and create vertical communties that are smart and share more facilities?

VerticalCity Sluisbuurt

And how can Amsterdam start thinking of new models for delivering clever vertical communities through intelligent densities?

VerticalCity Sluisbuurt

The modern concept of the vertical city where a singular tower or many connected together can solve all the issues related to urban life is outdated. The new vertical city is an intelligent densities concept that makes the city part of a sharing community, integrated in the real and virtual world. Recent technologies and social innovations are allowing us to rethink the concept of the residential tower and provide more quality for less in more surprising building concepts. As the popularity of urban liv12

VerticalCity Sluisbuurt

ing grows, and the desire to be more connected to public transportation increases, stacking program as a community of vertical buildings is now a matter of necessity instead of a choice. New requirements for carbon neutrality and green environmental targets will have direct impact on where and how we live. Tall buildings that are thin, varied, intelligent, adaptive, affordable, low emission, with shared amenities and street relationships are the future of vertical communties. 13

Why is Vancouverism a successful model? Vancouver tower blocks are oriented towards the water, are part of a consistent urban fabric on small compact parcels with amenities, place high rises and low rises next to each other, and have high plinths with strong street frontages.

Why is a city like Toronto growing so incredibly fast yet still remains liveable? All of Toronto’s high-rise projects are a direct result of city and provincial planning policies designed to fight sprawl and encourage urban “intensification.” In fact, 84 per cent of recent development in Toronto has been in places – like big intersections served by public transit – that are targeted as growth areas in the city’s official plan. As a result, “we are starting to see a greater acceptability for a more intensified form of living.” Ms. Keesmaat (Toronto’s Chief Urban Planner.)

VerticalCity Sluisbuurt

What else contributes to Torontoâ&#x20AC;&#x2122;s livability? Many Toronto neighborhoods take pride in being walkable. The pace of walking, rather than other forms of transport, encourages community building by creating vibrant street life. Plinths at the bases of towers foster pleasant environments for interaction between neighbours and visitors.

How well does a vertical city like Rotterdam perform? A recent study (M.de Nijs 2015) has revealed that only 20 percent of all the 108 high-rise buildings (+65 meters) built in the Netherlands from the period 2004 to 2015 have a plinth that provides conditions for a lively street scene. In conclusion, plinths and high-rises that are part of a block outperform plinths of stand-alone towers in terms of urban vitality and liveliness.

The Rise of the Skinny Tower New York City like many cities is experiencing a boom in luxury housing projects, including a series of super-tall residential towers that are now under construction in midtown Manhattan. Much taller, and ever thinner, the new condo towers racing skyward in Midtown Manhattan are setting new standards in high rise living, including price. More money can be made from housing people in the sky than ever before. In part, this is because a building full of apartments requires far fewer elevators than an office building with its armies of workers. It casts thinner shadows and creates a more â&#x20AC;&#x2DC;transparentâ&#x20AC;&#x2122; skyline. In addition, people are willing to pay a lot more money for better views like to Central Park, and they will pay an even greater premium for an apartment that occupies an entire floor. Tall skinny buildings maximize indoor space by transferring the structural system to the exterior of the building thus making the cores thinner, with colomn free interiors. Thin towers also provide greater access to stacked shared amenities and large stacked gardens.

Define highrise in relationship to its surroundings

• The function of the plinth is to facilitate interaction with public spaces, street level and surrounding buildings. It gives the public space an urban facade and articulates entrances. • The plinth has a strong relationship with the street. • The middle part has a strong relationship with the city. It can step back 3-5 meters from the street frontage. • The top of buildings have a special function such as luxury apartments, an observation deck and other facilities and installations.

Positioning

High-rises should be positioned diagonally, away from each other â&#x20AC;˘ Tall buildings should be generously away from each other so as to allow for more sunlight, and better views through, over and between buildings.

Sunlight

Use reflective surfaces to bounce light to strategic zones

High-rises in relationship to directing sunlight • Position a high-rise design so that there is sufficient daylight and ‘skyline view’ for the area; in particular, the streets, parks, public and private outdoor space.

VerticalCity Sluisbuurt

Wind

Setbacks prevent wind hindrance at street level and between buildings

High-rises need to be designed to minimize wind hindrance on the street level • Ensure that location and orientation of high-rise buildings create better air circulation and natural ventilation • Plinth roofs and greenery help in reducing wind at street level. • Back lying facades can be used to reduce fall winds. • Provide amenities like overhangs on the building at street level for protection against bad weather conditions for pedestrians. 38

VerticalCity Sluisbuurt

High Rise Block

Highrise living needs to be integrated within an urban block with varied heights

High-rise blocks should make a good transition with low-rise buildings, parks and public spaces. • Position high-rises at corners with a plinth so that they mark the edges of the streets, parks and open spaces. • Place entrances on the street and place ‘back of house‘ facilities in order to ensure quality of public spaces and parks. • Make sure the pavement is wide enough for cyclists, pedestrians, buffer zones and green front gardens. 39
