Geometry in Architecture
THE MATH and application in MODERN ARCHITECTURE By Alma Zalo

The preview. Examples of Architectural designs inspired by Mathematics
The motive and/or insight behind some designs. Advantages of such designs and the added-value. Is it all about the aesthetic value?

Petronas Towers – Kuala, Malaysia
Agora Tower – Taipei ,Taiwan

The never ending illusion
Flatiron building, also Fuller building- NY, USA Ripley’s Building - Ontario

The dancing building – Prague, Czech Republic
The crooked House – Sopot, Poland

The connection with Math.
Designing such enormities is a delicate balancing act. A building not only needs to be structurally sound and aesthetically pleasing, it also has to comply with planning regulations, bow to budget constraints, optimally fit its purpose and maximize energy efficiency. The design process is a complex optimization problem. Advanced digital tools can analyze and integrate the bewildering array of constraints to find optimal solutions. Math describes the shapes of the structures to be built, the physical features that have to be understood and, as the language of computers, forms the basis for every step of the modelling process.

Incorporating technology
With the help of computers you can model aspects of a building, from its physics to its appearance. Computer models can simulate things like the way the wind blows around the building or sound waves bounce around inside it. Graphic programs can explore different mathematical surfaces and populate them with panels of different textures. The information you get from these models can be pulled together in architectural CAD tool called parametric modelling. Parametric models allow you to change a variety of geometrical features while keeping fixed those features you have decided should not change.. A design team can explore a huge range of design options in a very short period of time; change geometric features of a building and see how the change affect aerodynamic properties, can explore how complex shapes that are hard to build can be broken down into simpler ones, can quickly calculate how much material is needed to estimate the cost. The results…

Note the giant helical stair case inside The use of glass and a giant helical staircase in the interior are supposed to symbolize the transparency and the accessibility of the democratic process.

More on CAD Surfaces that can be described by mathematical equations — such as slices of cones, tori, or spheres — often form the basis of designs. This is advantageous when it comes to creating virtual models, as mathematically generated surfaces are easily represented on a computer. Rather than describing a structure by a large number of individually stored co- ordinates, you only need to store an equation. The exact shape of the surface can be controlled by varying the parameters in the equation The motive and/or insight behind some designs.

A Mathematically generated surface
z = e-a(x^2+y^2) z is the vertical axis in the 3-D coordinate system. The number a determines the shape of the surface. The first surface has a=1 The second surface a=5 The third surface has a=7.
