Located in Philadelphia’s dynamic Northern Liberties neighborhood, The Q Tower is a 24-unit tower with an elevated ground floor world-class restaurant. The building occupies a previously vacant lot and continues the catalytic growth that the area is currently experiencing. The building has been developed as a ‘smart’ tower, with integrated systems reactive to its inhabitants. Our collaboration with Ted Selker of the Context Aware Computing Lab at MIT Media Lab is aimed toward integrating interactive living environments, developing the tower as a ‘learning’ structure. The MIT Media lab is recognized for its work in creating environments that use sensors and artificial intelligence to create so-called virtual sensors, adaptive models of users to create keyboard-less computer scenarios. Sensor technologies will facilitate the interaction of the users with the tower as a unit: RFID controlled ‘contactless’ fast-pass access, robotic storage, smart controls, with sensors for lighting, sound, and air-conditioning all increase ease of use and energy-efficiency. The collaboration has produced a wide range of innovations in the building systems: an in-car Smart Pass allows automatic parking access, will register the delivery ‘Smart Closets,’ and give feedback to a virtual doorman. All this will make the tower a responsive structure, easy to inhabit. Each living unit has been designed to be ‘special’ to its inhabitant. Algorithmic rule sets allocate room type and variation based on programmatic relationships, transparency percentage, and change in transition angles. All possible room transitions—experienced here as potential windows—are made available as an algorithmic set. Each potential transition is considered before the optimal window subset is chosen and the next decision tree is started. All trees are looping and linked, and are therefore affected by both past and future decisions. The result is an envelope that is able to respond fluidly to both the dynamic programmatic conditions within the building and to itself, re-thinking the relationship of window and façade to allow them to be integral to one another. The FTF—or file-to-factor—method was developed so that single continuous metal sheets can be shaped by computer-driven equipment according to algorithmically generated geometries, which are generated in a parametric software. This approach permits the structures to be modeled and easily fabricated, translating into reasonable costs.As environmental concerns increase, so too must we increase our responsible use of natural resources. Q-Tower is off the grid, using geo-thermal energy, smart lighting, and cooling controls on sensors. The use of local, recycled materials—glass-asphalt, recycled aluminum—and intelligent appliances further reduces the use of energy and resources.
