1 WIP 2017 PROJECT NAME CHALLENGE: The Tower is not only iconic and attractive, it is a highly innovative building using natural sources cleverly, preserving biodiversity and aiming to be affordable, efficient, healthy and safe. For it to be the most sustainable office high rise structures in Amsterdam this building needs to become NET ENERGY POSITIVE and NET CARBON POSITIVE. The Tower is part of a mixed use scheme with an art gallery and residential component at heart of the Knowledge Quarter of Zuidas, Amsterdam. STRATEGY: PROJECT LOCATION: Amsterdam, Netherlands TEAM: Jorge Beroiz Carlos Alba-Murillo Julia Azzoni Ekaterina Dziadkovskaia Pablo La Roche Arianne Ponce Denise Vilela Jan-Maurits Loecke OFFICE: London ID#: 137 In order to seriously protect the local environment and global climate a rethinking about buildings as such needs to take place. Inspired by nature we designed a building being like a tree that sequesters more carbon than it emits, adapts to its surrounding, responds to the climate. We developed a non-composite timber structure, which not only allows the building to store 3,500 metric tons of C02, but also adds to the speed of construction as well as to a healthier work/life environment. Together with engineers Atelier One and experts of the Cambridge University research group we looked into timber unique issues like fire, setting down, ageing timber, tempered interior climate, nodes and cross bracing. In addition to the landscaped internal atriums and open staircases promoting social interaction we developed a high performance envelope which could generate more than half a million kwh/year, maximize daylight while reducing summer solar gains and provide opportunities for natural ventilation. RESULTS/IMPACT: Not only this project introduces and develops new techniques and strategies, but by becoming the first non-composite high-rise timber structure it will be the first of its kind in the world and it could become the sustainable showcase for the client, for the city of Amsterdam and certainly for CallisonRTKL. We would be ahead of the game. The use of wood as a material has the full backing from of the planning department of Zuidas, Amsterdam. Once completed it will encourage others to create more green, sustainable, healthy buildings which not only reduces the pollution and energy consumption, in contrary, which contributes to the wellbeing of the communities and environment where is implemented.

2 This latest Tower for in Amsterdam is much more than only a contextual building responding to the masterplan and the EU s directive for new buildings to become energy neutral as much as possible by The aim is it to become the greenest and most sustainable office tower globally, a healthy building which not only reduces pollution and energy consumption, in contrary, which contributes to the wellbeing of the city, gives something back to the community. A building inspired by the nature, by the concept of the tree, which not only responds to the climate but actively cleans the air and produces oxygen, promoting biodiversity. Solar Energy plays a crucial role in this concept and by maximizing horizontal surfaces it informs the design of the building. Together with our environmental specialists and detailed energy modelling we optimized and developed the design of the skin of the building and its orientation. By positioning multi storey internal Atriums at the perimeter this Tower reveals its soul and heart towards the surrounding, rather than being an introverted fortress it becomes a building of light appearance, which engages with the community, honours the openness of the Dutch society. The aim is to give something precious back to the city by being a healthy and most innovative and successful workplace for Amsterdam, attracting young talent from everywhere, interacting with its inner life and the green calm atriums with the buzz of the. At the same time it clearly communicates its high performance energy agenda with its green roofs, solar panels and innovative climatic Atriums and once completed will become the greenest workplace of its time. The world tallest, non composite Timber structure Inspiration: External/Internal Gardens -> Dutch Polder, Dijk, Wetlands Solar Panels and Balconies -> Water, High Tide, Delta The Challenge: Achieve a positive net energy, positive net carbon office building The Big Idea: Amsterdam A building that is like a tree. A building that sequesters more carbon than it emits, storing in this case 3,500 metric tons of C02 A Building like a tree

3 Amsterdam A Building like a tree: 20 Storeys/ 91.6 m... in timber Arcadis Head Office Urban Design Legacy Inspired by Nature With its prominent location at the pedestrian Diagonal with Gustav Mahlerlaan at the end of Claude Debussylaan this building will become the most iconic new development of the new, Amsterdam Zuidas. Responding to the community and context the building envelope shifts slightly at the North to capture the most beautiful unobstructed views to the city centre Amsterdam. It addresses the prominent corner Diagonal/Mahlerlaan as well as on Ground floor level the North East Corner of the plot and sets an accent at the view axes of Claude Debussylaan. As the Dutch landscape is defined and influenced by water, its low and high tide, its ramified waterways and once in a while flooded pastures the Design is inspired by Polders and the water flowing around them. Sitting on top of the residential plinth by Rotterdam architects Powerhouse, CRTKL s tower raises 92m into the sky and would, if executed in wood, write architectural history by becoming the tallest timber structure in the world. The tower will accommodate Arcadis new headquarter at the top floors, other office tenants at lower levels, as well as a contemporary public restaurant on top of the residential roof. The building, in contrast to the mineral Plinth, is of organic language, embraced by horizontal external eyebrows, which flow around internal landscaped Atriums. The eyebrow s texture of laminated continuous PV on top is an additional reference to the flow of water. With its carefully designed proportion and details, bespoke shading devices and window transoms, the floor to floor high performance glass units and corresponding connections and nodes, this tower combines the sophisticated industrial architectural language of the early 20th century with the advanced parametric modelling, building technology and energy code of the 21st century.
