Advanced Geometry Analysis

Advanced Geometry Analysis

Federation of Korean Industries

For a building skin with complex or irregular geometry, it is critical to establish panel shapes and sizes that meet architectural requirements while being practical to fabricate, ship, erect and maintain. We optimize panelization using advanced geometry analysis tools to study multiple subdivision strategies. To define the building skin geometry itself, we write software scripts and use parametric modeling in geometry software that best fits each client’s needs. From concept studies to detailed steelwork, 3D modeling of façade joints, fabrication sequencing and erection engineering, our range of analysis capabilities can enhance the constructability of complex forms.

Skin Structural Analysis

Skin Structural Analysis

443 Greenwich Street, New York

Advanced building skins can involve concentrated forces and large deflections. Understanding and harnessing these structural behaviors is essential for properly performing building skin systems. Our 3D finite-element software tools for glazing, fabrics and skin-supporting elements enable large-deformation nonlinear analysis as well as plastic design for materials with nonlinear stress-strain behavior. Our understanding of the interplay between building skin and building structure informs our designs to provide coordinated, efficient results.

Thermal & Daylighting Analysis

Thermal & Daylighting Analysis

We evaluate the thermal performance of all types of building enclosures, from modern curtain walls to unique skins and historic systems, using a variety of analytical tools. When analysis identifies problems – such as condensation, thermal bridging and heat loss – we provide design solutions for new buildings and upgrades to existing façades. We recommend building skin options based on our in-depth knowledge of the specific performance properties of a wide range of materials. Thorough thermal and daylight analysis helps designers optimize building massing, orientation, glass selection, opening distribution and use of light shelves and shading devices.

Blast & Security Analysis

Blast & Security Analysis

Our design teams include professionals who have responded to some of the world’s worst structural failures, both natural and man-made. We apply the lessons learned to provide risk assessment services, using advanced analysis tools to assess and predict how building skin elements, such as masonry and glazing, and supporting structure may respond to loads associated with blast and other threats. We often couple these assessments with specialized studies to determine the risk of progressive collapse. Our building skin designers and structural engineers also use these powerful analytical tools to design new buildings and upgrades to existing facilities that are better able to withstand these events.
