The 2014 EcoBuild exhibition at London’s Excel centre opened this week and an egg-shaped plywood pavilion designed for OnGreening’s stand at the event is showcasing the work of Ramboll Computational Design (RCD).
OnGreening is a new web-based platform devoted to the research and profiling of green building technologies. The organisation required a pavilion and lecture theatre that would make them stand out from the crowd at the world’s largest event for sustainable design at the ExCel centre in London.
The look of the structure is intended to echo Ongreening’s goal of capturing and filtering the world’s knowledge of green data. The pavilion has already attracted a lot of attention.
The pavilion’s egg-like geometry was generated using form-finding techniques pioneered on previous RCD projects. The structure itself is unique in that it uses thin 6.5mm birch plywood timber laths which are bent into shape, creating a so-called ‘bending active’ structure which is incredibly stiff and acts like a monocoque, enabling the shell to carry most of the stresses.
The timber laths are aligned along geodesic lines between pre-seeded generation points set out using a parametric model. The primary geodesic members are restrained by secondary laths of the same narrow and thin profile of plywood with a simple bolted connection. This method allowed the use of straight and short length pieces of timber, making it more practical to purchase and build compared with other similar looking structures.
Further details about OnGreening and their work are available on their website.
The KREOD (formerly known as Dpod) pavilion, located at the North Greenwich Olympic site, has now been completed – a significant event as it marks the culmination of a challenging design and fabrication process.
KREOD is a sustainable, portable, demountable and multi-functional indoor or outdoor exhibition space that will be installed in multiple locations within London. The project is led by Pavilion Architecture with its organic form inspired by nature, resembling a seed.
KREOD will sits on castors allowing the structure to be moved and rearranged into different forms and spaces to create a versatile event space with practical considerations for transportation, storage, disassembly and reassembly.
The structure, which has taken some time to come to fruition, is made up of three reciprocal timber gridshells that implement a number of geometrical optimisation and fabrication algorithms that have not been previously applied to a real structure. The form is a creative response to the need for a building that can be easily erected and subsequently demounted by hand, uses Kebony timber – a previously untried material – of a given size and limited thickness, and had to be delivered within a strict budget.
Using digital technology to its fullest, KREOD has been delivered in a collaborative manner with each member of the design team understanding the innovative work and challenges of the other contributors and designing accordingly.
KREOD will be launched and unveiled to the media today at its current site, adjacent to the North Greenwich Arena in East London, where it will remain for six weeks before being moved to its next site.
The creators of Trada’s pavilion structure for Expo 2012 will be speaking about the inspiration, design and modelling of the freeform planar mesh plywood shell on 25th/26th September.
