NATIONAL MUSEUM OF WORLD WRITING

The city of Songdo, built over the years as an expression of the future Smart Cities typology where quality of life is combined with the different aspects of digital infrastructure, is now facing the challenge of creating a new element of life for the city, for the citizens and the future visitors. A space that serves as a fulcrum to make the city attractive internationally, capable of opening up to new inhabitants and offering to the existing a place where cultural initiatives are crossed with the life of the community. Choosing a museum that places Writing as its theme, from its origins to highlight the importance of community history, their distinctive features and their cultural evolution over the centuries, but also its possible future transformations and its new digital and physical configurations adopted over the next few years. A theme that is then declaimed not only in its cultural but also social definition as a place of intersection and exchange between the different cultures of this new cosmopolitan city united together by a new cultural and educational space. The new museum project lies within an essential natural context for the city and for its citizens. Cyclope pathways stretching along the entire length of the park, different levels of terrain suggesting unexpected views and experiences, the water that emphasizes the natural aspect of the site, are essential elements and reinterpreted in the conceptual and spatial definition of the project.

The technological aspect that shapes the way of life and interaction of Songdo’s citizens is instead reflected in the various experiences that can be experienced within the museum space: from the increased reality to amplify the possibilities offered by the different exposures to the possibilities of the citizens to interact directly from their home to the educational initiatives offered within the museum. Finally, the social aspect: a museum space not only for cultural initiatives but as a place for relationships, leisure and entertainment for the entire community of the city. Spatially and conceptually, the new project is defined according to the dual function of exhibition space linked to Levels (0.00m-12.00m) educational spaces and social relationships. A hybrid, multifunctional, community-based, and interHall / Exhibition rooms / Educational Rooms / Offices national vision. The planned circulation is conceived as a space, link, capable of communicating different spatial aspects of the project, such as exhibition and educational space, becoming itself an area of public / social characteristics, not forgetting the total spatial fusion that it has with the ‘natural element.

The main concept we decided to develop into the project is about spatial expansion. This idea was given by the necessity to design a museum able to change with time. Functionally the constant link made by the central circulation provides the possibilty for the museum property to play with the spaces and the functions in plan, extending some of them or not depending by the necessity of the moment, creating a new symphonic multifunctionality.

The Agent based Path exploration via Quelea on Grasshopper Setup:

Agent (particle capable of own decisions)= person:

   

- Max Speed 0.6 - Max force 0.008 - Vision Radius 6m - Vision Angle 100° - PolysurfaceEnvironment=Walkable Area

{ https ://vimeo.com/2 4 7 0 9 3 0 5 4 } The applied Rules:

Definition:

100 100 100 100

Boundaries Contain Force to keep Agents away from Environment boundaries=keep them from crowding on the edges Follow Path Force to move along and stay within a specified radius of a curve=make them follow a Main Path with 5m deviation radius Wander Force that causes the agent to randomly steer in a direction that is based off of its previous direction. (produces a seemingly realistic wandering behavior, rather than steering in a completely random direction) Seek Force to steer the Agent towards the point= Trying to gather around a point, that is moving along it‘s own path during the simulation(like a follow me car)

13.8 Avoid Obstacles=Exit Area(so they don‘t run to the exit right away) 35.9 Avoid Collision to steer the Agent away from a predicted potential collision (If Avoid Obstacle doesn‘t apply) 25 100 100

And, based on 3m Radius Neighbor information Allign to steer the Agent away from a predicted potential collision. based on 1m Radius Neighbor information Seperate to steer the Agent away from a predicted potential collision. and based on 1m Radius Neighbor information with 12.5° Vision Angle View to move the Agent laterally away from any Agent that blocks its view.
